Motion Re-estimation for MPEG-2 to MPEG-4 Simple Profile Transcoding
Since its emerging in mid 90’s, MPEG-2 [1] has been widely accepted by the digital video industry. There have been huge amount of video content stored in MPEG-2 format. MPEG4 [2] is the latest video coding standard out of MEPG targeted at network video applications. The Simple Profile (SP) of MPEG-4 is often used in practical applications. Thus, it is often necessary to perform MPEG-2 to MPEG-4...
متن کاملScalable module-based architecture for MPEG-4 BMA motion estimation
In this paper, we present a scalable module-based architecture for block matching motion estimation algorithm of MPEG-4. The basic module comprises one set of processing elements based on one-dimensional systolic array architecture. To support various applications, modules of processing elements can be configured to form the processing element array to meet the requirements, such as variable bl...
متن کاملMPEG-4 to MPEG-2 HDTV Network Video Transcoding
Much to the surprise of many cable operators, the industry's MPEG-4 era appears to have abruptly begun. Due to HBO's startling June announcement that it will begin beaming all 26 of its HBO and Cinemax multiplex channels in HDTV using the far more bandwidth-efficient video compression format, MSOs suddenly face the daunting challenge of figuring out how to carry all that MPEG-4 programming from...
متن کاملB-frame Transcoding in H.264 to MPEG-2 Transcoders
In this paper we review fast transcoding techniques for H.264/MPEG-2 B pictures. B pictures are a bidirectional prediction mode used by the H.264/AVC and MPEG-2 video compression standards. B pictures allow motion estimation (ME) to be performed using both backward and forward reference frames. This type of inter-prediction is highly effective but also highly complex making reduced complexity m...
متن کاملH.264/AVC to MPEG-2 Video Transcoding Architecture
Video transcoding is assuming an important role in modern video communication systems in order to allow interoperability between different equipment and standards. So far most effort has been spent in transcoding from older standards to the most recent ones. However, as new standards reach higher levels of compression efficiency, the diversity of bitstream formats also increases. In this paper ...
