AV1 and VVC Video Codecs: Literature Overview and Some ViTech Contributions
Language: Portuguese
Date: October 27th / 11h00 – 12h00
Abstract
This talk focuses on the state-of-the-art AOMedia Video 1 (AV1) format and Versatile Video Coding (VVC) standard. These codecs introduced several novel coding techniques compared to their predecessors to improve coding efficiency at the cost of a significant computational cost. The main novelties of these encoders are presented in this talk, including their novel partitioning schemes and encoding tools. Then, the main works in the literature targeting system-level solutions featuring complexity reduction and/or dedicated hardware designs for AV1 and VVC are discussed. Finally, some contributions of the Video Technology research group (ViTech) from the Federal University of Pelotas (UFPel) are also presented, including novel architectures targeting AV1 tools and novel complexity reduction solutions targeting VVC.
