Input Source
Select either CVBS (composite analog) or SDI (serial digital) for the input source.
Track Arming
The Image Server records video, audio and closed caption information as separate files that
comprise a clip. Video is always recorded; select the additional sources you wish to record.
For certain video material such as keys or wallpaper, no audio is needed. For analog audio
recording, a choice of zero or two audio channels is available. With digital audio, a choice of
zero, two, or four channels is available. Since the Image Server records 24-bit uncompressed
PCM, a worthwhile savings of disk-space can be achieved by turning off audio tracks when
they are not needed.
Audio Sample Rate Conversion
The Image Server always records audio at 48 kHz. Select Sample Rate Conversion to convert
off-speed digital audio sources to the Image Server’s 48 kHz internal clock rate.
Use Sample Rate Conversion with any 48K signal that is not referenced to either the same
source as genlock, or the digital outputs of the Image Server.
