    Publication Year: 1992, Page(s):10/1 - 10/5
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (348 KB)

    Studies on video compression for TV and HDTV applications have been carried out at the Research Centre of Radiotelevisione Italiana (RAI) since 1986. With the work accomplished in the framework of the European project EU 256, a contribution has been provided in the standardization activities of CMTT and ETSI for a codec to transmit conventional definition TV at 34 and 45 Mbit/s. The adopted video ... View full abstract»

  • 34 Mbit/s video codecs for distribution

    Publication Year: 1992, Page(s):9/1 - 9/6

    Advances in compression technology allied to parallel developments in digital processing and storage have led to the development of video codecs capable of providing subjectively excellent picture quality at comparatively modest data rates. The author describes a 34 Mbit/s codec and its associated monitoring and control arrangements that will be used by British Telecom for a particular broadcast q... View full abstract»

    Significant technological advances in low bit-rate video codecs and digital communications have opened up new opportunities for the broadcasting industry. The author describes an application that exploits these technologies to provide a relatively low-cost and highly mobile means of sending video material from remote locations back to the production studio. The application described has been devel... View full abstract»

  • Post production applications of video compression in broadcasting

    Publication Year: 1992, Page(s):5/1 - 528

    The author discusses how compression techniques can be applied to benefit production and post production in the broadcast industry. The author believes that it is in the area of storage that bit rate reduction offers distinct advantages in the broadcast studio environment. He discusses the benefits which bit rate reduction will bring to the digital VTR and also potentially to the digital disc reco... View full abstract»

  • Video compression techniques

    Publication Year: 1992, Page(s):2/1 - 214
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (612 KB)

    The author discusses video compression techniques with particular emphasis on the discrete cosine transform. The approach taken for the description of the principles is one of numerical example, to illustrate the underlying simplicity of the DCT coding approaches by the avoidance of a rigorous mathematical treatment. Another redundancy reduction technique, that of sub-band coding, is briefly menti... View full abstract»

    The Nordic HD-DIVINE (digital video narrowband emission) project has developed a prototype system for digital terrestrial HDTV, comprising an HDTV image codec, which compresses an HDTV signal down to 24 Mbit/s, and a radio modem based on the COFDM (coded orthogonal FDM) principle. The HDTV codec uses a very advanced method for the estimation and compression of motion vectors, and is optimised espe... View full abstract»

  • Data reduction for VTRs

    Publication Year: 1992, Page(s):3/1 - 3/9
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (352 KB)

    The author describes some simple aspects of information theory as applied to television signals and the reduction of data therein. He then explains the advantages of using data reduction in video tap recorders, particularly in HDTV, and why it has now become feasible to do so. A method of data reduction (using DCT and variable length coding) which has gained favour is briefly described, together w... View full abstract»
