2results about How to "Reduce codec complexity" patented technology

The embodiment of the invention provides a video encoding and decoding method and device, a computer readable medium and electronic equipment. The video decoding method comprises the following steps: determining a plurality of pixel regions in a current frame based on a preset pixel region size, wherein each pixel region comprises at least one pixel; determining a skipped area in the current frame according to whether each pixel area is processed in a skipped mode or not; and generating reconstruction data corresponding to the current block according to the position relationship between the current block to be decoded and the skipping region. According to the technical scheme of the embodiment of the invention, the coding and decoding efficiency can be improved, and the coding and decoding complexity can be reduced.

The application provides an audio encoding and decoding method, device, equipment, medium and program product; wherein the audio encoding method comprises: decomposing an audio signal to obtain a low-frequency sub-band signal and a high-frequency sub-band signal; performing multi-level feature extraction processing based on the low-frequency sub-band signal and the high-frequency sub-band signal to obtain sub-band signal features corresponding to multiple levels respectively; performing quantization processing on the sub-band signal features corresponding to each level to obtain index values of the sub-band signal features; performing encoding processing on the index values of the sub-band signal features to obtain code streams corresponding to the levels; and configuring corresponding transmission priorities for the code streams corresponding to the multiple levels respectively; wherein the transmission priority is positively correlated with a decoding quality index of the code stream corresponding to the level. The application can be flexibly applied to different network bandwidth application scenarios, and the efficiency and quality of audio encoding and decoding are improved.
