DSP-based multi-format video decoding engine for media adapter applications

There are four major components in a generic digital home framework: media center; set-top box; media adapter; portable viewer. We present a DSP-based multi-format video decoding engine for realizing the media adapter application. By choosing a powerful DSP core and designing an efficient and configurable software engine, the proposed solution is believed to possess both low-cost and high-flexibility. In our current implementation, the media adapter can decode various types of video formats, such as MPEG-1/2/4, H.264/AVC baseline, WMV 7/8/9 and DivX 3/4/5. In our simulation, videos up to SD resolution can be decoded seamlessly.
