摘要:
An apparatus, method, and system are described for transmitting a television program signal. A portion of a local frequency spectrum may be determined to be free, or relatively unused. A user selection of a television program or broadcast programming channel may be received from a program lineup in an electronic programming guide. The selected program may be selected from a gateway, translated, and transmitted over the portion of the frequency spectrum determined to be free. The translation may include converting a signal from the gateway into a National Television Systems Committee (NTSC) signal or a mobile TV signal.
