Abstract

The invention discloses a mode decision circuit in video coding, which comprises three parallel processing circuits, and is characterized in that when a first processing circuit carries out coding mode decision on four 4*4 units to obtain a first RDO value, a second processing circuit carries out coding mode decision on 8*8 units to obtain a second RDO value; a first comparison circuit comparing the first RDO value and the second RDO value to preserve the coding mode of the minimum value; a third processing circuit performs coding mode decision on the 16*16 unit to obtain a third RDO value; the second comparison circuit obtains a fourth RDO value according to the coding modes of the four 8*8 units stored by the first comparison circuit, and compares the fourth RDO value with the third RDO value to store the coding mode of the minimum value; the third processing single path performs coding mode decision on the 32*32 unit to obtain a fifth RDO value; and the third comparison circuit obtains a sixth RDO value according to the coding modes of the four 16*16 units stored by the second comparison circuit, and compares the sixth RDO value with the fifth RDO value to take the coding mode with the minimum value as a 32*32 coding mode, so that the aim of meeting the real-time processing requirement is fulfilled.

Description

technical field [0001] The invention relates to the technical field of video coding, in particular to a mode decision circuit in video coding. Background technique [0002] In video coding standards (such as AVS2, HEVC, etc.), generally support multiple coding mode divisions, such as CU (Coding Unit, coding unit), PU (Prediction Unit, prediction unit) and other coding mode divisions, and video coding standards support The size range of CU / PU is 4x4, 8x8, 16x16, 32x32 and 64x64. [0003] At present, in order to obtain the optimal division mode, by introducing the MD (Mode Decision, mode decision) module in the video encoder, the MD module selects the optimal coding mode division through the RDO (Rate Distortion Optimization, rate-distortion optimization) process, for the best encoding quality and performance. [0004] However, when the MD module executes the RDO process, it performs the RDO process in a serial manner for the division and size of various coding modes, and af...
