<p>PROBLEM TO BE SOLVED: To prevent a double voice output of the loudspeaker of a video camera and a loudspeaker connected to a computer when fetching voice from the video camera into the computer. SOLUTION: A switch 42 is closed by the reproducing operation of a user and video/audio information from a video camera 10 is impressed through an interface 40 and the switch 42 to a signal decoding circuit 48 and reproduced. A voice signal analytic circuit 44 analyzes the presence/absence of voice in a received signal and according to the analyzed result of the analytic circuit 44, when there are voice data, a mute mode managing circuit 54 makes a mute command generating circuit 56 generate a mute command. This command is transmitted from the interface 40 to the camera 10. According to this command, a command analytic circuit 30 of the camera 10 controls a mute circuit 24 and mutes the voice output of a loudspeaker 26.</p> |
