Abstract
During sleep mode, a power-source control section stops the power supply to a tuner, a demodulation section, an AV-data processing section and a microcomputer, and delivers a power supply only to a standby tuner. The standby tuner receives a start signal which is transmitted from a head end, using a frequency except a specific frequency which is received by the tuner, and outputs a power-supply instruction signal according to the start signal. The power-source control section executes a power supply to the tuner, the demodulation section, the AV-data processing section and the microcomputer, in response to the power-supply instruction signal.
