TL;DR: A brief technical overview of key coding techniques in AV1 is provided along with preliminary compression performance comparison against VP9 and HEVC.
Journal ArticleDOI
An Overview of Coding Tools in AV1: the First Video Codec from the Alliance for Open Media
Yue Chen,Debargha Mukherjee,Jingning Han,Adrian Grange,Yaowu Xu,Sarah Parker,Cheng Chen,Hui Su,Urvang Joshi,Ching-Han Chiang,Yunqing Wang,Paul Wilkins,Jim Bankoski,Luc Trudeau,Nathan E. Egge,Jean-Marc Valin,Thomas Davies,Steinar Midtskogen,Andrey Norkin,Peter de Rivaz,Zoe Liu +20 more
TL;DR: A technical overview of key coding techniques in AV1 is provided and the coding performance gains are validated by video compression tests performed with the libaom AV1 encoder against the libvpx VP9 encoder.
Proceedings ArticleDOI
An overview of new video coding tools under consideration for VP10: the successor to VP9
Debargha Mukherjee,Hui Su,James Bankoski,Alexander Jay Converse,Jingning Han,Zoe Liu,Yaowu Xu +6 more
TL;DR: A set of new experimental coding tools have already been added to baseline VP9 to achieve modest coding gains over a large enough test set, and this paper provides a technical overview of these coding tools.
Proceedings ArticleDOI
Novel inter and intra prediction tools under consideration for the emerging AV1 video codec
Urvang Joshi,Debargha Mukherjee,Jingning Han,Yue Chen,Sarah Parker,Hui Su,Angie Chiang,Yaowu Xu,Zoe Liu,Yunqing Wang,Jim Bankoski,Chen Wang,Emil Keyder +12 more
TL;DR: New tools in AV1 are described that improve the prediction of pixel blocks before transforms, quantization and entropy coding are invoked and improve intra, inter and combined inter-intra prediction.
Proceedings ArticleDOI
Efficient AV1 Video Coding Using a Multi-layer Framework
TL;DR: A new coding tool is presented that extends the total number of reference frames in both forward and backward prediction directions and a multi-layer framework is described, which suggests the encoder design and places different reference frames within one Golden Frame (GF) group to different layers.
