Patent number: 8446533Abstract: In an AV system in which a television apparatus and a recorder are individually connected to an AV amplifier through an HDMI, in the case where sound is output from the AV amplifier, if insertion of headphones into the television apparatus is detected, control information to switch the destination of the audio data is transmitted from the television apparatus to the AV amplifier. The AV amplifier switches the destination of the audio data that is input from the recorder from a speaker output section to the television apparatus in accordance with the control information. Thus, even if the headphones are inserted into the television apparatus while the AV amplifier is outputting sound reproduced by the recorder, the sound can be output from the headphones.Type: GrantFiled: August 27, 2009Date of Patent: May 21, 2013Assignee: Canon Kabushiki KaishaInventors: Yasushi Shikata, Takashi Yamamoto, Tomoyasu Yoshikawa, Katsuhiro Ito, Tomoki Kuroda, Kiyohiro Uemura, Masaki Tamura, Masatsugu Sasaki, Kinshirou Suzawa
