    "abstract": "In considering the issues for successful implementation of Digital Terrestrial Television Broadcasting, we can draw on a foundation of NTL's experience as the provider of the NTL 2000 digital video compression system world-wide, and over five years of study on the SPECTRE project in the United Kingdom. SPECTRE is concerned with all aspects of Digital Television including the low-bit rate video coding, modulation, frequency planning, and perhaps most important, practical field trials. The work was initiated under the Independent Broadcasting Authority, but since the IBA was abolished in 1990, it has been carried out by NTL, under contract from the Independent Television Commission in the UK.",
