Device for controlling power supplied to a satellite broadcast receiver
in a television
摘要:
A method and apparatus for controlling electrical power to a satellite broadcast receiver forming a part of a television device. The television device receives a command receiving a command (e.g. from a remote controller) to turn off electrical power. The television device determines if broadcast satellite recording is currently being executed, for example by an external VTR connected to an output port of the television device. If broadcast satellite recording is being executed, power is turned off power to a portion of the television device while retaining electrical power to the satellite broadcast receiver. If broadcast satellite recording is not being executed, power is turned off to the broadcast satellite receiver also.
