Relay apparatus controlling signal channel selection

摘要

A relay apparatus (10) is provided with: an image output unit (11); switches (SWa, SWb); a control unit (16) for controlling switches; and an obtaining unit (16) for obtaining a first CEC address associated with the relay apparatus if the relay apparatus is connected to an output apparatus (30). The control unit controls switches to select a signal channel connecting a first signal transmitting device (14) and a storage apparatus (20) if the first CEC address and a reproduction command are received. After connecting the relay apparatus and a unit (40), the control unit controls switches to select the signal channel connecting the first signal transmitting device and a second signal transmitting device (15) if the unit is in a video output state, and controls switches to select the signal channel connecting the first signal transmitting device and the image output unit if the unit is in a standby state.

1. A relay apparatus comprising:
a first signal transmitting device compliant with a high-definition multimedia interface (HDMI) standard for an interface; a second signal transmitting device compliant with another standard which is different from the HDMI standard; a storage apparatus; an image output unit configured to output a predetermined image; a switch configured to switch between a signal channel connecting the first signal transmitting device and the storage apparatus, a signal channel connecting the first signal transmitting device and the image output unit, and a signal channel connecting the first signal transmitting device and the second signal transmitting device; a control unit configured to control the switch; and an obtaining unit configured to obtain a first consumer electronic control (CEC) address which is a CEC address associated with said relay apparatus when said relay apparatus and an output apparatus are connected to each other via the first signal transmitting device, wherein the control unit controls the switch to select the signal channel connecting the first signal transmitting device and the storage apparatus when the first CEC address outputted from the output apparatus and a reproduction command are received, the obtaining unit obtains a second CEC address which is a CEC address associated with a unit compliant with the another standard when said relay apparatus is connected to the unit via the second signal transmitting device, and the control unit controls the switch to select the signal channel connecting the first signal transmitting device and the second signal transmitting device when the unit is in a video output state, and controls the switch to select the signal channel connecting the first signal transmitting device and the image output unit when the unit is in a standby state.
