摘要： An apparatus (200) for receiving a digital terrestrial broadcast television signal in combination with another signal from another source includes a modular housing (400) enclosing a radio frequency tuner (211) for receiving the digital terrestrial broadcast television signals and a consumer premise component (320). The consumer premise component (320) includes an external housing (310) enclosing a tuner (210) to receive the other signal and a modular port (330) to accept the modular housing. The modular housing (340) is disposable in the modular port (330). A diplexer (212) can be externally mounted to the apparatus (200). The diplexer (212) includes an input (147) to accept a combined radio frequency signal that includes the other signal and the digital terrestrial broadcast television signal; a first output (142) to couple to the tuner (210); and a second output (143) to couple to the removable radio frequency tuner (211). The diplexer (212) filters the combined radio frequency signal to select the other signal and couple the other signal to the first output (142) and filters the combined radio frequency signal to select the digital terrestrial broadcast television signal and couple it to the second output (143). The other signals include a cable television signal, a satellite television signal, and/or a high definition satellite television signal. The modular housing includes power connections (431) that are relatively shorter in length than the ground connections (432) so that during removal of the removable radio frequency tuner (340) the power connections (431) decouple from the consumer premise component (320) before the ground connections (432) and during insertion the ground connections (432) make contact before the power connections.
