Patent number: 9307189Abstract: 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.Type: GrantFiled: May 11, 2012Date of Patent: April 5, 2016Assignee: PIONEER DIGITAL DESIGN AND MANUFACTURING CORPORATIONInventors: Yasuhiro Rin, Takeshi Hashimoto, Yoshiyuki Shimizu, Satoshi Saitoh, Shinichiro Kinoshita, Tomoo Nishigaki
