a) A distribution scheme involving transmission of signals directly from satellites to homes. It does not carry the burden of terrestrial broadcasting’s restricted bandwidth and regulations and so is thought by many to be an ideal mechanism for the introduction of high base bandwidth ATV. DBS is the most effect delivery mechanism for reaching most rural areas; it is relatively poor in urban areas and in mountainous terrain, particularly in the north. Depending on the frequency band used, it can be affected by factors such as rain. b) Multiple television channel programming service that is transmitted direct from high powered satellites, directly to a home receiving dish.
