meet the Lum and Chroma goals. With Fixed Q mode, bytes/field can
increase beyond the system bandwidth, causing interference with other
channels.
- Bytes per Field is the target compression rate. Not every field requires the
target rate, it is simply the average rate the Disk Recorder tries. The higher
the rate, the better the picture detail. The actual
bytes/field depends on the
picture complexity, Min Lum Q , and Max Chroma . The algorithm
dynamically changes Min Lum Q and Max Chroma to make the field size
meet the target unless Fixed Q is selected.

Setting up the Signal Routing
Signal routing determines which physical input and output connections are
used by a panel. A crosspoint method is used to assign the physical connections
to the TimeDelay software panels.
Signal routing must be set up to obtain video input and output.
NOTE: The Controller for each channel must be set up before
assigning the crosspoints. Follow the instructions for “Configuring
a Controller” on page 268.
There are three steps:
• Setting video crosspoints.
• Setting up timecode.
• Assigning timecode crosspoints.
