An Overview of the DTTB Model

Recent advances in communication technology have brought digital transmission of television services from the realm of a future possibility to a near-term practical reality. The commonly held view is that the application of digital technology to the television sciences will provide higher picture and sound quality than conventional terrestrial television transmission and, at the same time, increase the efficiency of spectrum utilization by allowing multiple program services to be broadcast in current single-program channels. For digital services to be successful, there must be a consensus on standards in areas such as source and channel coding, modulation methods, content identification, and error protection and correction. A model of a digital terrestrial television broadcast (DTTB) system was developed by the International Telecommunications Union (ITU) Radio-communications Task Group 11/3 on Digital Terrestrial Television Broadcasting (DTTB) as a means of analyzing the system requirements. The model developed by the Task Group is described.
