Low Complexity Enhancement Video Coding
Low Complexity Enhancement Video Coding (LCEVC) is a standard for video compression that is defined by MPEG under the designation MPEG-5, Part 2. It specifies a data stream structure defined by two component streams, a base stream that can be decoded by a hardware decoder and an extension stream that is suitable for implementing software processing with sustainable power consumption. The enhancement stream offers new functions such as expanding the compression capability of existing codecs, reducing coding and decoding complexity for video-on-demand and live streaming applications.
Time schedule
The definition is planned for early to mid-2020. The final adoption of the standard should take place in October 2020.
motivation
The technical advancement of streaming is advancing rapidly, but it always takes a relatively long time until hardware solutions for new compression methods are available. Software solutions, on the other hand, are more flexible, but programming for the classic CPU quickly reaches its performance limits when processing video data. LCEVC aims to solve this problem by combining the advantages of both systems.
