Paper Abstract

Since the approval of the H.261 standard many compatible video codecs have been announced. These hardware systems are not versatile since they are generally based on proprietary chip sets specifically designed for that application. In this paper we describe an implementation of a H.261 compatible video codec based on a digital signal processor (DSP). Since most of the coding tasks are performed by the DSP, the system can be easily programmed by the user to implement other algorithms. When the system is programmed for the H.261 algorithm, it is capable of encoding and decoding 15 Hz QCIF bit streams.
