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 ...

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 ...

IEEE Transactions on Broadcasting, 1981
The transmitter of a video codec system is designed and realized in ECL hardware. This video codec system is capable of carrying one commercial NTSC color television channel with a program audio channel at a rate of 42.9 Mb/s. The transmitter interfaces with a DPCM processor.

Subjective and Objective Video Codec Evaluation
2011 15th Panhellenic Conference on Informatics, 2011This paper describes the methodology and the results of the objective and subjective evaluation of four codecs: AVC/H.264, VC-1, MPEG-4 Visual, and MPEG-2. The standard -- based evaluation procedure has been applied on three video sequences and produced 576 file versions and interesting benchmarking results.

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.

Dirac was started off by British Broadcasting Corp. (BBC) in 2003 as an experimental video coding system based on wavelet technology, which is different from that used in the main proprietary/standard video compression systems. Over the years, Dirac has grown out of its initial development and it is now on offer as an advanced royalty-free video coding
