Video transcoding, due to its high practical values for a wide range of networked video
applications, has become an active research topic. We outline the technical issues and …

A transcoder architecture that provides the lowest possible complexity with a small error, eg,
for converting an MPEG-2 bitstream into an MPEG-4 bitstream. The transcoder reads header …

From the Publisher: Compressed Video Communications addresses the compression and
transmission of coded video streams over mobile IP networks. By analysing a broad …

Methods and apparatus for performing 2: 1 downscaling on video data are provided. At least
one input matrix of NXN (eg, N= 16) Discrete Cosine Transform (DCT) coefficients is formed …

A novel fully comprehensive mobile video communications system is proposed. The system
exploits the useful rate management features of video transcoders and combines them with …

The H. 264 standard achieves much higher coding efficiency than the MPEG-2 standard,
due to its improved inter-and intra-prediction modes at the expense of higher computational …

Recent developments have given birth to H. 264/AVC: a video coding standard offering
better bandwidth to video quality ratios than previous standards (such as H. 263, MPEG-2 …

This paper presents a novel macroblock mode decision algorithm for inter-frame prediction
based on machine learning techniques to be used as part of a very low complexity MPEG-2 …

Third generation mobile communication systems will provide more advanced types of
interactive and distribution services, and video is one of the most prominent applications for …
