    Publication Year: 1996, Page(s):298 - 303
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (704 KB)

    This paper looks at the prospects for niche/thematic channels as the pay TV industry shapes up to digital. It suggests there is a breed of channels, dubbed `independents', that can add value, variety, depth and originality to digital services and channel bouquets, much as currently happens in the world of published consumer magazines. However, such independent TV services have struggled to find di... View full abstract»

    The paper describes a study undertaken to assess the data requirements of the three different frame types of MPEG-2; `I' frames, `P' frames and `B' frames. There are many ways that a combination of these three frame types can be configured to make up a group-of-pictures (GOP) and the intention of this paper is to provide a basis upon which different GOP sequences can be compared. For example: in a... View full abstract»
