eneral Video Coding (MPEG-5) will contain new video coding specifications.
- Part 1 – Essential Video Coding will specify a video codec with two layers. The first layer will provide a significant improvement over AVC but significantly less than HEVC and the second layer will provide a significant improvement over HEVC but significantly less than to VVC.
- Part 2 – Low Complexity Video Coding Enhancements will specify a data stream structure defined by two component streams, a base stream decodable by a hardware decoder, and an enhancement stream suitable for software processing implementation with sustainable power consumption. The enhancement stream will provide new features such as compression capability extension to existing codecs, lower encoding and decoding complexity, for on demand and live streaming applications. Figure 61 sketches an LCEVC decoder.
