Does the DTV system support services other than entertainment programming?
Yes. Broadcasters, if they so choose, are able to transmit-in addition to entertainment programming-a variety of information through the data bitstream to enhance TV programs or to provide entirely new services. For example, TV programs can be broadcast with a variety of languages and captions, and sports programs can be broadcast so that the individual viewer can call up player statistics, game scores, or other information. Broadcasters could also, for example, transmit to your television an entire edition of a newspaper, sports information, computer software, telephone directories, stock market updates, interactive educational material, or any other information that can be translated into digital bits. The ATSC DTV system is a 19.4 Mb/s pipeline that can be used for the delivery of a wide variety of digital services.
