    Most professional FM radio transmitters are capable of accepting baseband signals from 40 Hz to 100 kHz. Stereo programme transmissions require a base bandwidth up to 53 kHz, which leaves a potential capacity for other baseband signals in the range 53 to 100 kHz. In the United States this capacity has been exploited for some years, and various systems are in operation under the generic title of Su... View full abstract»

  • Fixed, adaptive, and motion compensated interpolation of interlaced TV pictures

    Publication Year: 1988, Page(s):220 - 223
    Cited by:  Papers (5)  |  Patents (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (308 KB)

    All current broadcast TV systems make use of interlace to reduce the bandwidth required. However this makes it difficult to perform processes such as freeze frame, slow motion, picture geometry manipulation, standard conversion and display up-conversion. These would prefer to treat each field separately, but each field contains only half of the TV lines. The ability to perform good interpolation o... View full abstract»

    The authors show how the transmission/display standards can be expected to evolve for satellite broadcasting based on the MAC standard. Furthermore, the possibilities for evolution of the studio standard through to an HDTV standard of 1250/50/2:1 or 1250/50/1:1 are considered. Such evolution of both studio and display standards is made possible by the combination of the MAC system for use in satel... View full abstract»

    The HDTV European approach is based on a high definition 1250/50/1 standard using progressive scanning. The interest for such a standard is very understandable since progressive scanning facilitates greatly video signal processing and improves final subjective aspect of picture. But, these advantages are counter-balanced by some drawbacks such as very high video bandwidth and very high speed proce... View full abstract»
