摘要

AV1是一种新兴的开源和免版税视频压缩格式,由开放媒体联盟(AOMedia)行业联盟于2018年初共同开发并最终确定。AV1开发的主要目标是在保持实际解码复杂性和硬件可行性的同时,实现比最先进的编解码器更大的压缩增益。本文简要介绍了AV1中关键编码技术的技术概况,并与VP9和HEVC进行了初步的压缩性能比较。

An Overview of Core Coding Tools in the AV1 Video Codec
AV1 is an emerging open-source and royalty-free video compression format, which is jointly developed and finalized in early 2018 by the Alliance for Open Media (AOMedia) industry consortium. The main goal of AV1 development is to achieve substantial compression gain over state-of-the-art codecs while maintaining practical decoding complexity and hardware feasibility. This paper provides a brief technical overview of key coding techniques in AV1 along with preliminary compression performance comparison against VP9 and HEVC.
