Abstract
An information processing apparatus including a baseband signal manager, a determining unit, and a power supply controller is connected to one or more apparatus via an interface. The interface includes a signal channel for transmitting baseband signals and a control channel for bidirectionally transmitting control signals. The baseband signal manager transmits a baseband signal sent from a first apparatus to a second apparatus as-is when the information processing apparatus is in a standby power state. The determining unit determines the power state of the second apparatus on the basis of a control signal sent from the second apparatus. When it is determined by the determining unit that the second apparatus is not powered on, the power supply controller suspends power supply to the baseband signal manager.
