2016 Data Compression Conference (DCC), 2016
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.

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 ...

Superresolution-Enabled Video CODEC
2020 54th Asilomar Conference on Signals, Systems, and Computers, 2020Video compression forms a critical bandwidth management tool for streaming video applications. Lossy compression techniques such as MPEG-4 currently predominate but remain distortion limited. In this work, a complementary approach is employed whereby a frame is cast as logical sum of spectra associated with objects and edge-contours bordering objects ...

A scalable video codec for layered video streaming
Real-Time Imaging, 2004A wavelet-based video codec that performs layering of encoded bit streams to support layered scalable video streaming is presented in this paper. The proposed codec can generate separate bit streams comprising different cumulative layers. A new sorting algorithm is incorporated to produce spatial and temporal resolution scalable bit streams, and a ...

An improved framework of distributed video codec
2011 18th International Conference on Telecommunications, 2011Recently, distributed video coding (DVC) has become a hot research topic, as its low complexity encoder and high complixty decoder can suit for many emerging applications. However, the practical performance gap between DVC and traditional video coding is still large and need more research about it.
