Image Server 2000
Figure 19: Channel 1 Input Configuration Window
Input Source
Select either CVBS (composite analog), or SDI (serial digital) for the input source.
Track Arming
The Image Server 2000 records video, audio and closed caption information as separate files
that comprise a clip. Video is always recorded; select the additional sources you want to
record.
For certain video material such as keys, wallpaper, etc., no audio may be 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 may be made. Since the Image Server records 24-bit
uncompressed PCM, a worthwhile saving of disk-space can be achieved by turning off audio
track assignments when making video clips that do not require audio.
Audio Sample Rate Conversion
The Image Server always records audio at 48 kHz. Select Sample Rate Conversion to convert
off-rate digital audio sources to the 48 kHz sample clock rate used by the Image Server.
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.
