Abstract
A decoder adapted to generate an intermediate decoded version of a video frame from an encoded version of the video frame, determine either an amount of high frequency basis functions or coefficients below a quantization threshold for at least one block of the video frame, and generate a final decoded version of the video frame based at least in part on the intermediate decoded version of the video frame and the determined amount(s) for the one or more blocks of the video frame, is disclosed. In various embodiments, the decoder may be incorporated as a part of a video system.
Claims30
A method comprising:
- generating an intermediate decoded version of a video frame from an encoded version of the video frame;
- determining either an amount of high frequency basis function or coefficients below a quantization threshold for at least one block of the video frame;
- and
- generating a final decoded version of the video frame based at least in part on the intermediate decoded version of the video frame and the determined amount(s) for the one or more blocks of the video frame.
A decoder comprising
- means for generating an intermediate decoded version of a video frame from an encoded version of the video frame;
- means for determining either an amount of high frequency basis function or coefficients below a quantization threshold for at least one block of the video frame;
- and
- means for generating a final decoded version of the video frame based at least in part on the intermediate decoded version of the video frame and the determined amount(s) for the one or more blocks of the video frame.
A system comprising:
- a receiver adapted to receive an encoded version of a video frame;
- and
- a decoder coupled to the receiver, and adapted to
- generate an intermediate decoded version of the video frame from the encoded version of the video frame,
- determine either an amount of high frequency basis function or coefficients below a quantization threshold for at least one block of the video frame, and
- generate a final decoded version of the video frame based at least in part on the intermediate decoded version of the video frame and the determined amount(s) for the one or more blocks of the video frame.
