Abstract

The invention discloses a video decoding method which comprises the steps that a converting unit and a prediction unit obtained after video compression bitstream decoding are converted into M * M residual blocks and M * M prediction blocks respectively, wherein M is equal to 16 or 8 or 4, a video compression bitstream comprises one of an HEVC bitstream, a VP9 bitstream and an AVS2.0 bitstream; according to the residual blocks and the prediction blocks, reestablished image blocks are obtained; and the reestablished image blocks are subjected to filtering, and decoding reestablished images are obtained. The invention further discloses a video decoder. Module development of the multi-protocol video decoder is lowered, and the area and the power consumption of the video decoder are lowered.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a video decoding method and a video decoder. Background technique [0002] Video compression technology is widely used in Internet, TV broadcasting, storage media and communication and other fields. Since the MPEG (Motion Pictures Experts Group) standard was established in 1993, after years of inheritance and development, a large number of video compression formats coexist. So far, a commercial video decoder needs to support at least a dozen video compression formats, such as MPEG-1, MPEG-2, MPEG-4, H.263, H.264, H.265, Real8, Real9, VC1 , AVSP2, VP8, VP9 and DIVX etc. This has brought serious challenges to the video decoder, especially the rise of smart devices, which has put forward strict requirements on the area and power consumption of the hardware video decoder. [0003] Protocols before 2013, such as (MPEG-1, MPEG-2, MPEG-4, H.263, H.264, Real8, Real9, VC1, AVSP2, VP8, V...
