The Thor video codec is being developed by Cisco with the intention to use only royalty-free coding tools. The video codec is based on the well-known block-based hybrid video coding approach, but with some significant changes compared to existing standards such as AVC/H.264 and HEVC/H.265.

2012 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2012
Video content is routinely acquired and distributed in digital format. Therefore, it is customary to have the content encoded multiple times. In this paper we consider a processing chain of two coding steps and we propose a method that aims at identifying the type of codec used in the first step, by analyzing its coding-based footprints.

QoE Assessment of Video Codecs for Video Streaming over 5G Networks
World Symposium Communication Engineering, 2020Nowadays, the need for more efficient video compression algorithms is growing, due to the increasing consumption of video content in higher resolutions. Thus, it is obvious that video compression technologies play a key role in the distribution of video ...

An architecture for the universal video codec
ICASSP '86. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005Several video codec applications are currently considered and there is a danger that digitisation will lead to more incompatibilities than experienced in the analogue era. A video codec architecture is thus proposed having the property to accomodate a wide range of coding algorithms (hybrid scheme), to operate on a wide bitrate range (by means of an ...
