Throughout this article, we concentrate on the transcoding of block-based video coding
schemes that use hybrid discrete cosine transform (DCT) and motion compensation (MC). In …

Many of the forthcoming video services and multimedia applications are expected to use
preencoded video for storage and transmission. Video transcoding is intended to provide …

This paper discusses the problem of transcoding H. 263-based video streams. Two different
models for transcoding are examined, rate reduction and resolution reduction. Results show …

In transcoding, simply reusing the motion vectors extracted from an incoming video bit
stream may not result in the best quality. In this paper, we show that the incoming motion …

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

Transcoding is a key technique for reducing the bit rate of a previously compressed video
signal. A high transcoding ratio may result in an unacceptable picture quality when the full …

In multimedia applications, it is often necessary to adapt the bit rates of the coded video bit
streams to the available bandwidths of various communication channels. Because different …

In order to cater to the diversity of terminals and networks, efficient, and flexible adaptation of
multimedia content in the delivery path to end consumers is required. To this end, it is …

This paper presents the different issue of video streaming algorithms without compromising
the video quality in the distributed environment. Our theme of this research is to manage the …
