    In order to transmit the HDTV signal in 6 MHz, the four United States digital HDTV proponents, the DigiCipher, DSC-HDTV, ADTV and ATVA-P systems, are reducing the video data rate of HDTV to 15-17 Mb/s, a compression ratio of approximately 60-70 times. The high compression dictates that channel coding be used to avoid block errors and multiframe error propagation. High efficiency in channel utiliza... View full abstract»

    The roles that digital high-definition television (HDTV) compression techniques play in HDTV applications, such as digital HDTV terrestrial broadcasting, are discussed. Images can be encoded intraframe and/or interframe, depending on the requirement of compression rate and the picture quality. Using source coding, redundancy in the spatial and temporal domains can be greatly reduced while preservi... View full abstract»

    The three key elements of the advanced digital television (ADTV) system are described. These elements are source coding based on MPEG++ data compression, channel coding based on a prioritized data transport, and modulation techniques based on spectrally shaped QAM. The performance of the ADTV system is discussed View full abstract»

    In the United States, consideration is underway to provide for the terrestrial emission of high-definition television (HDTV) signals in the existing VHF/UHF allocations. Analyses show that it may be necessary to reduce cochannel spacings to a minimum of 160 km if the vast majority of existing terrestrial broadcasters are to be accommodated with an HDTV service in addition to their NTSC capability....
