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 …

One of the fundamental challenges in deploying multimedia systems, such as telemedicine,
education, space endeavors, marketing, crisis management, transportation, and military, is …

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 …

In this work, transcoding of pre-encoded MPEG-1, 2 video into lower bit rates is realized
through altering the coding algorithm into H. 261/H. 263 standards with lower spatio …

MPEG-2 bitstream into an MPEG-4 bitstream. The transcoder reads header information from
an input bitstream and provides a corresponding header in the new format for the output …

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 …

With the advances of the digital information revolution and the societal changes they have
prompted, it has become critical to facilitate secure management of content usage and …

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