Next-Generation Video Compression Techniques

MPEG is working on requirements for a new video codec, expected to be completed by 2020. The future-generation codec is anticipated to provide a 50 percent bitrate reduction compared with HEVC Main profile for the same perceptual quality. While this is sufficient for certain use cases, it may justify a future video coding standard for other use cases that require bitrate reductions higher than 50 percent. This paper will look at the target applications for the new video codec that include 8K, VR in 3DoF and 6DoF, the state of IP networks. This paper will present how new techniques can be used to reach a factor four compression efficiency vs. HEVC by 2020 using the next-generation MPEG codec. This is possible by leveraging new techniques such as content-aware encoding, elastic encoding, machine learning techniques, and pre- and post-processing pairing that uses metadata to signal how to post process video after decoding.
