CAMERA LINK RECORDER

摘要

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.

主权项

1. A camera link recorder comprising:
an HDMI receiver for receiving an audio clock signal of a camera according to an HDMI signal transmitted from the HDMI-linked camera; a signal processing section for subjecting an input audio signal to digital conversion and encoding and storing the signal; and a control section for supplying the audio clock signal as a master clock signal of the signal processing section when the audio clock signal generated by the HDMI receiver is at a predetermined frequency corresponding to the signal processing section, and for supplying an internal clock signal as the master clock signal of the signal processing section when there is not the audio clock signal or when the audio clock signal is not at a predetermined frequency corresponding to the signal processing section.
