Abstract
A method decodes a video encoded as a compressed bitstream including frames constructed as blocks. The bitstream is variable length decoded and inverse quantized to determine motion vectors and DCT coefficients of the blocks of the bitstream. The DCT coefficients are then inverse discrete cosine transformed. A low-resolution block is generated for each reconstructed block, and the reconstructed blocks are motion compensated with the low-resolution blocks to decode the video.
Claims13
A method for decoding a video encoded as a compressed bitstream encoded as a plurality of blocks, comprising:
- variable length decoding and inverse quantizing the bitstream to determine motion vectors and DCT coefficients of the blocks of the bitstream;
- inverse discrete cosine transforming the DCT coefficients;
- generating, for each reconstructed block, a low-resolution block;
- and
- motion compensating the reconstructed blocks with the low-resolution blocks to decode the video.
