A DSP based MPEG-2 video decoder for HDTV or multichannel SDTV

This paper describes a DSP based MPEG-2 video decoding software. The proposed decoder is able to reconstruct with full quality, in real-time, a sequence in HDTV format (corresponding to a subset of the MP@HL configuration) or up to three SDTV sequences (corresponding to the MP@ML configuration). The developed implementation is based on single DSP, reducing the cost and enabling an easy upgrading of the system with new capabilities. The chosen device is the high performance TMS320C64x DSP by Texas Instruments. The target applications are the transcoding devices, video servers and all professional digital video equipments.
