Multimedia applications of self-synchronizing T-codes

Abstract

The convergence of multimedia applications, which include such diverse sources as video, audio and computer data, places harsh demands on the communications process. Source coding is an important step in the communications process. A good source-coding scheme is characterized by its high efficiency in removing redundancy inherent in the information source. It should also ensure data integrity and be suitable for different data types. Codeword synchronization is an important aspect of any data communications system, whether it is a wireline or wireless system. Traditionally, block codes are used for source coding to reduce uncertainties in synchronization. The authors propose the application of minimal sync-delay T-codes for information source coding. The aim is to facilitate widespread deployment of efficient codes that also have intrinsically strong synchronizing performance.
