Abstract

The invention discloses a video coding framework based on an HEVC standard. On the premise that the HEVC standard is satisfied, modes (coding complexity cost model and coding distortion cost model) are adopted to quantitatively calculate candidate coding modes and coding parameters and ergodic picking over is performed, which avoids a mass of and complex processes of ergodic picking over and improves the coding rate-distortion performance. The method provided by the invention can improve the research result of the HEVE video coding performance, further improve the video coding performance and realize more efficient HEVC video coding strategy.

Description

Technical field: [0001] The invention belongs to the field of video coding and processing, and in particular relates to a video coding implementation framework based on the HEVC standard. Background technique: [0002] Under the requirements of high-definition (1080P) and ultra-high-definition (2K, 4K) video coding technologies such as H.264, the data rate generated by the coding increases sharply, which brings huge challenges to the storage and network transmission of video data. Shock, the existing coding technology has been difficult to adapt. Therefore, it is imperative to propose a coding technique with better compression ratio. To solve this problem, the JCT-VC (Joint Collaborative Team on Video Coding) working group has developed a new generation of video compression standard HEVC (High Efficiency Video Coding) with higher compression efficiency. Compared with the existing coding standard H.264 / AVC, HEVC can save about 50% of the coding bit rate when the objective q...
