Abstract
The disclosure provides a video decoding method and a video decoding device. An initial stream is received. In a first flow cycle, entropy decoding is performed on a plurality of first frames in parallel according to the initial stream by a plurality of entropy decoders of a plurality of processing cores, so as to generate a plurality of first decoded streams respectively corresponding to the first frames. In the first flow cycle, a second decoded stream is decoded by a plurality of coding tree unit decoders of the processing cores, so as to reconstruct a second frame.

A video decoding method, comprising:
- receiving an initial stream, wherein the initial stream comprises a stream of a plurality of first frames and a stream of a second frame;
- in a first flow cycle, performing entropy decoding on the stream of the first frames in parallel by a plurality of entropy decoders of a plurality of processing cores to generate a plurality of first decoded streams respectively corresponding to the first frames;
- and
- in the first flow cycle, decoding a second decoded stream by a plurality of coding tree unit decoders of the plurality of processing cores to reconstruct the second frame, wherein the second decoded stream is generated by performing entropy decoding on the stream of the second frame.
A video decoding device, comprising:
- a memory recording an initial stream, wherein the initial stream comprises a stream of a plurality of first frames and a stream of a second frame;
- a plurality of processing cores, wherein each of the processing cores comprises an entropy decoder and a coding tree unit decoder;
- a plurality of the entropy decoders coupled to the memory;
- and
- a plurality of the coding tree unit decoders coupled to the memory,
- wherein in a first flow cycle, the entropy decoders perform entropy decoding on the stream of the first frames in parallel to generate a plurality of first decoded streams respectively corresponding to the first frames, and
- in the first flow cycle, the coding tree unit decoders decode a second decoded stream to reconstruct the second frame, wherein the second decoded stream is generated by performing entropy decoding on the stream of the second frame.
