| Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
| Basis of Presentation and Summary of Critical Accounting Policies | Basis of Presentation and Summary of Critical Accounting Policies In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments (consisting of normal recurring adjustments) necessary to fairly present our financial position, results of operations and cash flows for the periods presented. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts therein. Due to the inherent uncertainty involved in making estimates, actual results in future periods may differ from those estimates. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted. The balance sheet at April 28, 2012 has been derived from the audited financial statements at that date, but it does not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. These financial statements should be read in conjunction with our financial statements and notes thereto for the year ended April 28, 2012, which are contained in our Annual Report on Form 10-K previously filed with the Securities and Exchange Commission. The results of operations for the interim periods presented are not necessarily indicative of results that may be expected for any other interim period or for the full fiscal year. Recent Accounting Pronouncements In June 2011, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income. The ASU amends guidance for the presentation of comprehensive income. The amended guidance requires an entity to present components of net income and other comprehensive income in one continuous statement, referred to as the statement of comprehensive income, or in two separate, but consecutive statements. The previous option to report other comprehensive income and its components in the statement of shareholders’ equity has been eliminated. Although the new guidance changes the presentation of comprehensive income, there are no changes to the components that are recognized in net income or other comprehensive income under existing guidance. In the first quarter of fiscal 2013, we revised our presentation of comprehensive income to conform to the guidance in this ASU. In September 2011, the FASB issued ASU No. 2011-08, Intangibles – Goodwill and Other (Topic 350): Testing Goodwill for Impairment. Under this new standard, entities testing goodwill for impairment now have an option of performing a qualitative assessment before having to calculate the fair value of a reporting unit. If an entity determines, on the basis of qualitative factors, that it is more-likely-than-not that the fair value of the reporting unit is less than the carrying amount, the existing quantitative impairment test is required. Otherwise, no further impairment testing is required. This ASU will be effective for impairment tests after April 29, 2012. The adoption of this standard is not expected to have a material impact on our consolidated results of operations or financial condition, as this ASU impacts the analysis to be performed. In July 2012, the FASB issued ASU 2012-02, Intangibles - Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment. The amended guidance gives entities the option to perform a qualitative impairment assessment to determine whether it is more likely than not that an indefinite lived intangible asset is impaired. An entity must identify and evaluate changes in economic, industry and entity-specific events and circumstances that could affect the significant inputs used to determine the fair value of an indefinite-lived intangible asset and whether it is more-likely-than-not that the fair value exceeds its carrying amount. ASU 2012-02 is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012 with early adoption permitted. The adoption of this amended guidance is not expected to have a material impact on our consolidated results of operations or financial condition. |

| Earnings Per Share [Abstract] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Earnings Per Share EPS | Earnings Per Share (“EPS”) Basic EPS is computed by dividing income (loss) attributable to common shareholders by the weighted average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that would occur if securities or other obligations to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then share in our earnings. The following is a reconciliation of the income and common share amounts used in the calculation of basic and diluted EPS for the three months ended July 28, 2012 and July 30, 2011:
Options outstanding to purchase 3,133 shares of common stock with a weighted average exercise price of $14.11 for the three months ended July 28, 2012 and 1,658 shares of common stock with a weighted average exercise price of $19.07 for the three months ended July 30, 2011 were not included in the computation of diluted earnings per share because the effects would be anti-dilutive. |

| Goodwill | Goodwill The changes in the carrying amount of goodwill related to each reportable segment for the three months ended July 28, 2012 were as follows:
We perform an analysis of goodwill on an annual basis as of the first business day of our third quarter of each year and more frequently if circumstances warrant. We last performed this analysis as of October 30, 2011. The result of that analysis indicated that no goodwill impairment existed as of that date. We face a number of risks to our business which can adversely impact cash flows in each of our business units and cause a significant decline in the fair values of each business unit. This decline could lead to an impairment of goodwill in some or all of our business units. Certain events, such as a worsening trend of orders and sales without a corresponding way to preserve future cash flows or a significant decline on our stock price, could cause a further impairment in goodwill. |

| Segment Disclosure | Segment Disclosure We have organized our business into five business units which meet the definition of reportable segments under Accounting Standards Codification ("ASC") 280-10, Segment Reporting: the Commercial segment, the Live Events segment, the Schools and Theatres segment, the Transportation segment, and the International segment. These segments are based on the type of customer and geography. Our Commercial segment primarily consists of sales of our video, Galaxy®, Fuelight™ and Valo™ product lines to resellers (primarily sign companies), outdoor advertisers, national retailers, quick-serve restaurants, casinos and petroleum retailers. Our Live Events segment primarily consists of sales of integrated scoring and video display systems to college and professional sports facilities and convention centers and sales of our mobile display technology to video rental organizations and other live events type venues. Our Schools and Theatres segment primarily consists of sales of scoring systems, Galaxy® displays and video display systems to primary and secondary education facilities and sales of our Vortek® automated rigging systems for theatre applications. Our Transportation segment primarily consists of sales of our Vanguard® and Galaxy® product lines to governmental transportation departments, airlines and other transportation related customers. Our International segment consists of sales of all product lines outside the United States and Canada. Segment reports present results through contribution margin, which is comprised of gross profit less selling costs. Segment profit excludes general and administration expense, product development expense, interest income and expense, non-operating income and income tax expense. Assets are not allocated to the segments. Depreciation and amortization, excluding that portion related to non-allocated costs, are allocated to each segment based on various financial measures. In general, segments follow the same accounting policies as those described in Note 1 of our Annual Report on Form 10-K. Unabsorbed costs of domestic field sales and services infrastructure, including most field administrative staff, are allocated to the Commercial, Live Events, and Schools and Theatres segments based on cost of sales. Shared manufacturing, building and utilities and procurement costs are allocated based on payroll dollars, square footage and various other financial measures. We do not maintain information on sales by products, therefore, disclosure of such information is not practical. The following table sets forth certain financial information for each of our five operating segments for the periods indicated:
No single geographic area comprises a material amount of net sales or long-lived assets net of accumulated depreciation other than the United States. The following table presents information about net sales and long-lived assets in the United States and elsewhere:
We are not economically dependent on a limited number of customers for the sale of our products and services because we have numerous customers world-wide. We are not economically dependent on a limited number of suppliers for our inventory items because we have numerous suppliers world-wide. |

| Commitments and Contingencies Disclosure [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Commitments and Contingencies | Commitments and Contingencies Litigation: We are involved in various claims and legal actions arising in the ordinary course of business. In the opinion of management, based upon consultation with legal counsel, the ultimate disposition of these matters, taken as a whole, will not have a material adverse effect on our consolidated financial statements. Guarantees: In connection with the sale of equipment to various customers, we have entered into contractual arrangements whereby we agreed to repurchase equipment at the end of the lease term at a fixed price. Our total obligations under these fixed price arrangements were $1,285 as of July 28, 2012 and April 28, 2012. We have recognized a guarantee liability in accrued expenses for the amount of $185 in accordance with the provisions of ASC 460, Guarantees, in connection with these arrangements. Warranties: We offer a standard parts coverage warranty for periods varying from one to five years for all of our products. We also offer additional types of warranties that include on-site labor, routine maintenance and event support. In addition, the terms of warranties on some installations can vary from one to ten years. The specific terms and conditions of these warranties vary primarily depending on the type of the product sold. We estimate the costs that may be incurred under the warranty obligations and record a liability in the amount of such estimated costs at the time the revenue is recognized. Factors that affect our estimate of the cost of our warranty obligations include historical experience and expectations of future conditions. We periodically assess the adequacy of our recorded warranty reserves and, to the extent that we experience any changes in warranty claim activity or costs associated with servicing those claims, our warranty obligation is adjusted accordingly. Changes in our warranty liability for the three months ended July 28, 2012 consisted of the following:
Performance guarantees: We have entered into standby letter of credit agreements, bank guarantees and surety bonds with financial institutions relating to the guarantee of future performance on contracts, primarily construction type contracts. As of July 28, 2012, we had outstanding letters of credit agreements, bank guarantees and surety bonds in the amount of $4,193 and $25,916, respectively. Performance guarantees are issued to certain customers to guarantee the operation and installation of the equipment and our ability to complete a contract. These performance guarantees have various terms, which are generally less than one year. Leases: We lease vehicles and office space for various sales and service locations throughout the world, including manufacturing space in the United States and China and various equipment. Some of these leases, including the lease for manufacturing facilities in Sioux Falls, South Dakota, include provisions for extensions or purchase. The lease for the facilities in Sioux Falls, South Dakota can be extended for an additional three years past its current term, which ends December 31, 2016, and it contains an option to purchase the property subject to the lease from January 1, 2015 to December 31, 2016 for $8,400, which approximates fair value. If the lease is extended, the purchase option increases to $8,600 for the year ending December 31, 2017 and $8,800 for the year ending December 31, 2018. Rental expense for operating leases was $718 and $856 for the three months ended July 28, 2012 and July 30, 2011, respectively. Future minimum payments under noncancelable operating leases, excluding executory costs such as management and maintenance fees, with initial or remaining terms of one year or more consisted of the following at July 28, 2012:
Purchase commitments: From time to time, we commit to purchase inventory, advertising, and various other products and services over periods that extend beyond a year. As of July 28, 2012, we were obligated under the following conditional and unconditional purchase commitments, which included $1,000 in conditional purchase commitments.
Allowance for doubtful accounts: During the first quarter of fiscal 2013, we became aware of circumstances that could cause an increase in our allowance for doubtful accounts in an amount between $0 and $2,500. These circumstances arise out of a contract for which payment by our customer is dependent on funding from a local government entity that is not under any legal obligation to pay our customer. |

| Income Taxes | Income Taxes We are subject to U.S. Federal income tax as well as the income taxes of multiple state jurisdictions. As a result of the completion of examinations by the Internal Revenue Service on prior years and the expiration of statutes of limitations, fiscal years 2009, 2010, 2011 and 2012 are the only years remaining open under statutes of limitations. Certain subsidiaries are also subject to income tax in several foreign jurisdictions which have open tax years varying by jurisdiction beginning in fiscal 2004. As of July 28, 2012, we had $452 of unrecognized tax benefits that would affect our effective tax rate if recognized. We recognize interest and penalties related to income tax matters in income tax expense. |

| Fair Value Disclosures [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Fair Value Measurement | Fair Value Measurement ASC 820, Fair Value Measurements and Disclosures, defines fair value as the price that would be received to sell an asset or paid to transfer the liability (an exit price) in an orderly transaction between market participants at the measurement date. It also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The fair value hierarchy within ASC 820 distinguishes between the following three levels of inputs that may be utilized when measuring fair value. Level 1 - Quoted prices in active markets for identical assets or liabilities. Level 2 - Observable inputs other than quoted prices included within Level 1 for the assets or liability, either directly or indirectly (for example, quoted market prices for similar assets and liabilities in active markets or quoted market prices for identical assets or liabilities in markets not considered to be active, inputs other than quoted prices that are observable for the asset or liability, or market-corroborated input.) Level 3 - Unobservable inputs supported by little or no market activity based on our own assumptions used to measure assets and liabilities. The fair values for fixed-rate contracts receivable are estimated using discounted cash flow analysis based on interest rates currently being offered for contracts with similar terms to customers with similar credit quality. The carrying amounts reported on our consolidated balance sheets for contracts receivable approximate fair value and have been categorized as a Level 2 fair value measurement. The carrying amounts reported for variable rate long-term marketing obligations approximate fair value. Fair values for fixed-rate long-term marketing obligations are estimated using a discounted cash flow calculation that applies interest rates currently being offered for debt with similar terms and underlying collateral. The total carrying value of long-term marketing obligations reported on our consolidated balance sheets approximates fair value and have been categorized as a Level 2 fair value measurement. The following table sets forth by level within the fair value hierarchy our financial assets and liabilities that were accounted for at fair value on a recurring basis at July 28, 2012 and April 28, 2012 according to the valuation techniques we used to determine their fair values. There have been no transfers of assets or liabilities among the fair value hierarchies presented.
The following methods and assumptions were used to estimate the fair value of each class of financial instrument. There have been no changes in the valuation techniques used by us to value our financial instruments. Cash and cash equivalents: Consists of cash on hand in bank deposits and highly liquid investments, primarily money market accounts. The fair value was measured using quoted market prices in active markets. The carrying amount approximates fair value. Restricted cash: Consists of cash and cash equivalents that are held in bank deposit accounts to secure issuances of foreign bank guarantees. The fair value of cash equivalents was measured using quoted market prices in active markets. The carrying amount approximates fair value. Certificates of deposit: Consists of time deposit accounts with original maturities of less than three years and various yields. The fair value of these securities was measured based on valuations observed in less active markets than Level 1 investments from a third party financial institution. The carrying amount approximates fair value. U.S. Government securities: Consists of U.S. Government treasury bills, notes, and bonds with original maturities of less than three years and various yields. The fair value of these securities was measured using quoted market prices in active markets. U.S. Government sponsored entities: Consist of Fannie Mae and Federal Home Loan Bank investment grade debt securities that trade with sufficient frequency and volume to enable us to obtain pricing information on an ongoing basis. The fair value of these securities was measured based on valuations observed in less active markets than Level 1 investments. The contractual maturities of these investments vary from one month to three years. Municipal obligations: Consist of investment grade municipal bonds that trade with sufficient frequency and volume to enable us to obtain pricing information on an ongoing basis. The contractual maturities of these investments vary from two to three years. The fair value of these bonds was measured based on valuations observed in less active markets than Level 1 investments. Derivatives – currency forward contracts: Consists of currency forward contracts that trade with sufficient frequency and volume to enable us to obtain pricing information on an ongoing basis. The fair value of these securities was measured based on valuation from a third party bank. See Note 11 for more information regarding our derivatives. The fair value measurement standard also applies to certain non-financial assets and liabilities that are measured at fair value on a nonrecurring basis. For example, certain long-lived assets such as goodwill, intangible assets and property, plant and equipment are measured at fair value in connection with business combinations or when an impairment is recognized and the related assets are written down to fair value. We did not make any material business combinations or recognize significant impairment losses during the first three months of fiscal 2013 or in all of fiscal 2012. |

| Marketable Securities | Marketable Securities We have a cash management program which provides for the investment of cash balances not used in current operations. We classify our investments in marketable securities as available-for-sale in accordance with the provisions of ASU 320, Investments – Debt and Equity Securities. Marketable securities classified as available-for-sale are reported at fair value with unrealized gains or losses, net of tax, reported in other comprehensive income (loss). Unrealized losses considered to be “other-than-temporary” are recognized currently in earnings. The cost of securities sold is based on the specific identification method. Where quoted market prices are not available, we use the market price of similar types of securities that are traded in the market to estimate fair value. As of July 28, 2012 and April 28, 2012, our available-for-sale securities consisted of the following:
Realized gains or losses on investments are recorded in our consolidated statements of operations within other expense, net. Upon the sale of a security classified as available-for-sale, the security’s specific unrealized gain (loss) is reclassified out of "accumulated other comprehensive (loss) income” into earnings based on the specific identification method. In the three months ended July 28, 2012 and July 30, 2011, the reclassifications from accumulated other comprehensive (loss) income to net assets were immaterial. Realized gains and losses on sales and maturities of investments were immaterial in the three months ended July 28, 2012 and July 30, 2011. All available-for-sale securities are classified as current assets, as they are readily available to support our current operating needs. The contractual maturities of available-for-sale debt securities as of July 28, 2012 were as follows:

| Receivables [Abstract] | |
| Receivables | Receivables We sell our products throughout the United States and in certain foreign countries on credit terms that we establish for each customer. On the sale of certain products, we have the ability to file a contractor’s lien against the product installed as collateral and to file claims against surety bonds to protect our interest in receivables. Foreign sales are at times secured by irrevocable letters of credit or bank guarantees. Accounts receivable are reported net of an allowance for doubtful accounts of $2,117 and $2,398 at July 28, 2012 and April 28, 2012, respectively. We make estimates regarding the collectability of our accounts receivable, long-term receivables, costs and estimated earnings in excess of billings and other receivables. In evaluating the adequacy of our allowance for doubtful accounts, we analyze specific balances, customer creditworthiness, changes in customer payment cycles, and current economic trends. If the financial condition of any customer was to deteriorate, resulting in an impairment of its ability to make payments, additional allowances may be required. We charge off receivables at such time as it is determined that collection will not occur. Charge offs of receivables and our allowance for doubtful accounts related to financing receivables are not material to our financial results. In connection with certain sales transactions, we have entered into sales contracts with installment payments exceeding six months and sales type leases. The present value of these contracts and leases is recorded as a receivable as the revenue is recognized in accordance with generally accepted accounting principles, and profit is recognized to the extent that the present value is in excess of cost. We generally retain a security interest in the equipment or in the cash flow generated by the equipment until the contract is paid. The present value of long-term contracts and lease receivables, including accrued interest and current maturities, was $19,365 and $18,452 as of July 28, 2012 and April 28, 2012, respectively. Contract and lease receivables bearing annual interest rates of 5.8 to 10.0 percent are due in varying annual installments through May 2023. The face amount of long-term receivables was $19,585 as of July 28, 2012 and $21,494 as of April 28, 2012. Included in accounts receivable as of July 28, 2012 and April 28, 2012 was $341 and $783, respectively, of retainage on construction-type contracts, all of which is expected to be collected in one year. |

| Derivative Instruments and Hedging Activities Disclosure [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Derivative Financial Instruments | Derivative Financial Instruments We utilize derivative financial instruments to manage the economic impact of fluctuations in currency exchange rates on those transactions that are denominated in currencies other than our functional currency, which is the U.S. dollar. We enter into currency forward contracts to manage these economic risks. We account for all derivatives on the balance sheet as an asset or liability measured at fair value, and changes in fair values are recognized in earnings unless specific hedge accounting criteria are met for cash flow or net investment hedges. If such hedge accounting criteria are met, the change is deferred in shareholders’ equity as a component of accumulated other comprehensive income. The deferred items are recognized in the statement of operations in the period the derivative contract is settled. As of July 28, 2012 and April 28, 2012, we had not designated any of our derivative instruments as accounting hedges, and thus recorded the changes in fair value in the other expense, net. The foreign currency exchange contracts in aggregated notional amounts in place to exchange United States Dollars at July 28, 2012 and April 28, 2012 were as follows:
As of July 28, 2012 and April 28, 2012, there was a net liability of $253 and $95, respectively, representing the fair value of foreign currency exchange forward contracts, which was determined using Level 2 inputs from a third party bank. |

| Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
| Recently Issued Accounting Pronouncements | Recent Accounting Pronouncements In June 2011, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income. The ASU amends guidance for the presentation of comprehensive income. The amended guidance requires an entity to present components of net income and other comprehensive income in one continuous statement, referred to as the statement of comprehensive income, or in two separate, but consecutive statements. The previous option to report other comprehensive income and its components in the statement of shareholders’ equity has been eliminated. Although the new guidance changes the presentation of comprehensive income, there are no changes to the components that are recognized in net income or other comprehensive income under existing guidance. In the first quarter of fiscal 2013, we revised our presentation of comprehensive income to conform to the guidance in this ASU. In September 2011, the FASB issued ASU No. 2011-08, Intangibles – Goodwill and Other (Topic 350): Testing Goodwill for Impairment. Under this new standard, entities testing goodwill for impairment now have an option of performing a qualitative assessment before having to calculate the fair value of a reporting unit. If an entity determines, on the basis of qualitative factors, that it is more-likely-than-not that the fair value of the reporting unit is less than the carrying amount, the existing quantitative impairment test is required. Otherwise, no further impairment testing is required. This ASU will be effective for impairment tests after April 29, 2012. The adoption of this standard is not expected to have a material impact on our consolidated results of operations or financial condition, as this ASU impacts the analysis to be performed. In July 2012, the FASB issued ASU 2012-02, Intangibles - Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment. The amended guidance gives entities the option to perform a qualitative impairment assessment to determine whether it is more likely than not that an indefinite lived intangible asset is impaired. An entity must identify and evaluate changes in economic, industry and entity-specific events and circumstances that could affect the significant inputs used to determine the fair value of an indefinite-lived intangible asset and whether it is more-likely-than-not that the fair value exceeds its carrying amount. ASU 2012-02 is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012 with early adoption permitted. The adoption of this amended guidance is not expected to have a material impact on our consolidated results of operations or financial condition. |

This element represents the portion of the balance sheet assertion valued at fair value by the entity whether such amount is presented as a separate caption or as a parenthetical disclosure. Additionally, this element may be used in connection with the fair value disclosures required in the footnote disclosures to the financial statements. The element may be used in both the balance sheet and disclosure in the same submission. This item represents Available-for-sale Securities which consist of all investments in certain debt and equity securities neither classified as trading or held-to-maturity securities. A debt security represents a creditor relationship with an enterprise. Debt securities include, among other items, US Treasury securities, US government securities, municipal securities, corporate bonds, convertible debt, commercial paper, and all securitized debt instruments. An equity security represents an ownership interest in an enterprise or the right to acquire or dispose of an ownership interest in an enterprise at fixed or determinable prices. Equity securities include, among other things, common stock, certain preferred stock, warrant rights, call options, and put options, but do not include convertible debt. An entity may opt to provide the reader with additional narrative text to better understand the nature of investments in debt and equity securities which are categorized as Available-for-sale.

This element represents the portion of the balance sheet assertion valued at fair value by the entity whether such amount is presented as a separate caption or as a parenthetical disclosure. Additionally, this element may be used in connection with the fair value disclosures required in the footnote disclosures to the financial statements. The element may be used in both the balance sheet and disclosure in the same submission. This item includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the Company may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Reference 1: http://www.xbrl.org/2003/role/presentationRef
