Abstract

A system (100) for providing broadcasting services is disclosed. The system includes a digital channel database (101) for storing a program from a broadcaster; a computer network (105) for accessing and distributing the program as a data stream; a tower controller (109) for receiving the program data stream from the computer network; and at least one transmitter selected by the tower controller (109) to receive the data stream and to broadcast the program to end-user receivers (119, 121, 123).
