Abstract
The present disclosure relates to an information processing apparatus and an information processing method which are capable of reducing consumption of standby power of an HDMI-CEC support device. An AV amplifier which is an HDMI-CEC support device and serves as an HDMI repeater transmits a polling signal to a television receiver which is an HDMI-CEC support device and serves as an HDMI sink based on the premise that it is connected via an HDMI cable at predetermined time intervals, and the AV amplifier is regarded as being connected via the HDMI cable as long as an ACK is received. Then, after the HDMI cable is removed, no ACK is returned to the AV amplifier, the HDMI cable is regarded as being removed accordingly, and thus an operation of a CPU of the AV amplifier is stopped, whereby power saving is achieved. The present disclosure can be applied to an HDMI-CEC support device.
