This application report describes the implementation of the MPEG-2 video decoder on the TMS320C62x DSP. The MPEG-2 video standard specifies the decompression and coded representation for entertainment-quality digital video, and is widely used in different digital video systems including DVB, DTV, DVD, DSS, etc. The decoder software implements all the MPEG-2 main-profile-at-main-level functionality, and conforms to the eXpressDSPE Algorithm Standard (xDAIS) to enhance reusability. This report describes different aspects of the decoder software, including algorithm overview, coding guidelines, decoder APIs, memory requirement, and performance.
