A sound recording apparatus is provided which is HDMI-connected to a camera and another device, which outputs a video image signal from the camera to the other device without processing, and which outputs to the other device, without degradation, an audio signal recorded separately from the camera. A sound recording apparatus is HDMI-connected to a camera and a backup image recording apparatus. The sound recording apparatus includes an HDMI receiver that receives an HDMI signal transmitted from the HDMI-connected camera, a controller that embeds an audio signal which is input from a microphone which is connected to the apparatus in an audio channel portion of the HDMI single, and an HDMI transmitter that outputs to the backup image recording apparatus the video image signal included in the HDMI signal and the audio signal embedded by the controller.

Camera-connection-type sound recording apparatus

There is provided a camera link recorder capable of recording sounds by a clock signal synchronized with a clock signal of a camera. A recorder is linked to a camera by means of an HDMI cable, and others. An HDMI receiver of the recorder reproduces an LRCK signal, which is an audio clock signal of a camera, from the HDMI signal, and outputs the LRCK signal. A CPU outputs a clock signal, which is generated from the LRCK signal when a frequency of the LRCK signal corresponds to a predetermined frequency of an audio CODEC, as a master clock signal to the audio CODEC. In other case, the clock signal generated from the internal clock signal CLK is output as a master clock signal to the audio CODEC.

Camera link recorder

A DVD recorder system having a sleep state. When a predetermined period of a non-operation state has elapsed, a key controller switches the state of a power source circuit to interrupt voltage supply, thereby causing the system to shift to the sleep state. In this state, when a signal is input from the video input terminal, the key controller controls the power source circuit to turn ON, thereby causing the system to shift to the normal state. After recovery to the normal state, a DVD processor provides instructions to a DVD drive in accordance with recording conditions which are prestored in an EEPROM, and supplies an input video signal to the DVD drive so as to start recording. Also, when a medium is inserted in the DVD drive, the key controller detects an insertion signal to control the power source circuit to turn ON, thereby causing the system to return to the normal state.
