| A System and Method for H.264 To MPEG-2 Video Transcoding 
Description The H.264 to MPEG-2 transcoder enables applications and services that can leverage the high compression efficiency of H.264 for network distribution and the existing MPEG-2 infrastructure for decoding at the receiver. H.264 video can be used to distribute video at lower bitrates and hence lower costs. Since virtually all the digital TVs and set-top-boxes today use MPEG-2, the video is then transcoded to MPEG-2 and played on a set-top-box at home (receiver). The complexity of the transcoder can be reduced by utilizing the information gathered during the H.264 decoding stage. The invention is novel in that it reduces the complexity of MPEG-2 encoding by leveraging the information from the H.264 decoding stage. The MB mode, motion vector search range, and motion vector search window are dynamically determined to reduce the encoding complexity. Potential Applications - IPTV
- Digital Cable
- DVR/TiVo
State of Technology Development and Commercialization The algorithms have been developed and validated through experimental evaluation. MPEG-2 and H.264 reference software from the MPEG committee was used for validation.
