Abstract:
1. A method for transmitting digital video data having a plurality of data blocks, the method including: encoding a video data block to a coded data block, wherein the encoding comprises: forming a prediction block associated with the video data block; calculating a residual block by subtracting the prediction block from the video data block; transforming the residual block; quantizing the transformed residual block; and forming the coded data block by encoding the quantized transformed residual block utilizing entropy coding; converting the coded data block to a transcoded data block incorporating the prediction block and the residual block associated with the video data block, wherein the converting comprises: decoding the coded data block into the quantized transformed residual block; forming the prediction block corresponding to the video data block; transforming and quantizing the prediction block; summing the quantized transformed residual and the quantized transformed prediction blocks; and generating the transcoded data block by encoding the summation; and transmitting the transcoded data block as part of an encoded bitstream to a decoder for decoding; and adjusting a ratio of the transcoded data blocks and the coded data blocks in the bitstream.
