Zusammenfassung: | A composite television broadcast receiver is provided to make cable connection easy by receiving satellite broadcasting signals, a ground wave broadcasting signal and a cable broadcasting signal via a single cable. A filter unit(200) allows a plurality of satellite broadcasting signals and a ground wave broadcasting signal received via a single cable(CA) to pass by different frequency bands set in advance. A low-noise amplification unit(300) amplifies the broadcasting signals applied from the filter unit by a preliminarily set degree. A distribution circuit(400) distributes the broadcasting signals amplified by the low-noise amplification unit to a plurality of tuner modules(600). A buffer amplification unit(500) amplifies the broadcasting signals distributed by the distribution circuit and outputs them to the tuner modules. A satellite antenna selection unit(100) selects one of satellite antennas. An RF(Radio Frequency) modulation unit(700) modulates a base band signal. |
