Firstly the paper reports experimental results proving that Cascaded Pixel Domain Transcoder (CPDT) is extremely inefficient when used for AVC/H.264 bitstream transcoding aimed at bitrate reduction not exceeding 30% of primary bitrate. In the paper, proposed is a transcoder that exploits structured truncation of bitsream and an algorithm for such truncation(More)
The paper deals with transcoding of AVC/H.264 bitstreams where some bitrate reduction is required. For single-layer bitstreams, often Cascaded Pixel Domain Transcoders (CPDT) are used unaware of the fact that such transcoders are complex and very inefficient when used for bitrate reduction not exceeding 30% of the primary bitrate. In order to avoid these(More)
