Apparatus for dynamically adjusting video decoding complexity, and associated method
First Claim
1. An apparatus for dynamically adjusting video decoding complexity, the apparatus comprising:
- a decoding resolution control circuit configured to dynamically determine, based on system capability of the apparatus and a target frame rate of a plurality of frames, whether at least one portion of the plurality of frames is to be decoded in accordance with a predetermined resolution differing from any intended resolution of the plurality of frames; and
an adaptive spatial resolution decoder circuit configured to decode the at least one portion of the plurality of frames according to the predetermined resolution by partially omitting encoded data of the at least one portion of the plurality of frames.

Abstract
An apparatus for dynamically adjusting video decoding complexity includes a decoding resolution control circuit and an adaptive spatial resolution decoder. The decoding resolution control circuit is arranged to dynamically determine whether at least one portion of multiple frames should be decoded in accordance with a specific resolution differing from an original resolution of the frames. In addition, the adaptive spatial resolution decoder is arranged to decode the frames according to whether the at least one portion of the frames should be decoded in accordance with the specific resolution. In particular, the apparatus further includes a system capability analyzing circuit arranged to analyze system capability of at least a portion of the apparatus, in order to generate analyzing results for being sent to the decoding resolution control circuit. An associated method is also provided.
