A Practical Integration of Key MPEG-2 Technologies

MPEG-2 is the premier coding scheme used widely in Digital Television Broadcasting. As a flexible compression scheme, MPEG-2 can be potentially and effectively used at every stage in the broadcast system. In acquisition, Betacam SX can be used as an MPEG-2 camcorder with a simple stream converter. An optical disk camcorder with an MPEG-2 Intra-frame encoder is currently being developed. In contribution/distribution, a narrow band channel requires high efficiency in compression. 4:2:2 long GOP is predominantly used in this application. — What would be the compression scheme of choice in the broadcast studio? The SMPTE/EBU Task Force has recommended 50Mbps Intra-frame coding and this is expected to become an ITU-R Recommendation shortly. The 50Mbps Intra-frame compression schemes based on MPEG-2 and DV are both believed to be applicable for high quality applications. — With MPEG-2 50M Intra-frame compression, the link which has been missing from broadcast studio stage now provides seamless interconnectivity. A full MPEG-2 compliant broadcast chain can now be created. — The paper will focus on MPEG-2 implementation of the broadcast chain as a whole. An instance of a practical MPEG-2 compliant broadcast system is considered with supplementary explanation of the essential MPEG-2 technologies, such as transcoding, splicing, and SDTI CP interfaces. $B!H (Jhistory Data $B!I (J, which is a form of $B!H (Jmetadata $B!I (J from t forms of Metadata.
