A Programmable and Scalable Architecture for Real Time Audio and Video Processing

Current Real Time Audio Video Processing demands flexible architectures and programmability in order to better match the application. — According to these requirements a fully programmable system, which extensively uses DSP technology, is presented. It is based on a VME bus structure and implements a scalable architecture. — Through extendible modular layers the computational power can be progressively increased and easily managed to perform different tasks. These features are particularly suited for implementing algorithms which are specified for different levels of quality/complexity like in the present MPEG2 standard (from MP@ML to HP@HL) [3]. — The software programmability of the system also enable to further improve and refine the current algorithm implementation without any hardware change. — The system has been developed within the framework of the EUREKA 1187 – ADTT project to allow, in particular, real time experimentation of Audio Video Non Broadcast Applications like Electronic Movie and Video Communication for professional environments.
