例如，監視組裝生產線的攝像機能把視頻數據饋送到萬能服務器的數據庫，該數據庫能探測出異常，如缺陷，並能觸發糾錯動作，從而以較低的成本改進了產品的質量。Reed - solomon codes have advantage of correcting bursting error and random error together, especially to the former. because its correcting capability amounts to the utmost correcting capability of block correcting codes, rs codes are widely used in telecom technology and data storage system
Reed - solomon （ rs ）碼具有同時糾正突發錯誤和隨機錯誤的能力，且糾正突發錯誤更為有效，其糾錯能力達到了分組糾錯碼的極限，因而被廣泛地應用於數據通信和數據存儲系統的差錯控制中。The proposed md mesh - based motion coding methodis then combined with the pairwise correlating transform, and acomplete md video coding scheme is proposed. further measures are takento reduce the mismatch between the encoder and decoder that occurs whenonly one description is received and the decoder reconstruction isdifferent from the encoder. the performance of the proposed scheme isevaluated using computer simulations, and the results show, compared toreibman s md transform coding mdtc method, the proposed schemeachieves better redundancy rate distortion performance
數據重傳必然會引起延遲，因而在需要很短延遲的應用中是行不通的，如雙向無線通信同時在以廣播方式進行數據傳輸時也是行不通的當有大量突發錯誤時，糾錯碼如分組糾錯碼block code及卷積碼convolutional code無法在不產生額外延遲及需要額外運算的前提下對數據提供足夠的保護而錯誤掩蔽的性能則受接收到數據與丟失數據之間的殘留相關性大小的影響。Then the designation and actualization of a data recorder that would be used in a fighter was introduced in details. also the means used to make the recorder more reliable as well as some features for the sake of anti - jamming and self - correction were depicted. the following part is about the fast programmable flash read - only - memory including its usage and features
