We conducted a case study of an h264 decoder design that demonstrates our tmoc scheme provides a significant reduction in chip area and power overhead for online checkers at the cost of increased. Abstract: we present two case studies of different architectures for h264 video decoder the objective of this case study is to show the design methodology that can maximize the flexibility of video decoder first, h264 is designed based on configurable processor the configurable processor was. Unlike mpeg-2, in h264/avc, multiple frames can be used for reference, the reference frames can be located either in past or future arbitrarily in display order, the hrd also specifies a model of the decoded picture buffer management to ensure that excessive memory capacity is not needed in a decoder to store the pictures used as references. This case study is modeled after an actual customer request for design assistance in the gaming industry because of the high number of hd ip cameras in a dense deployment, hundreds of cameras within the maximum distance of 100 meters for ethernet, it may be practical to implement a physically isolated lan infrastructure for transporting.
