Grass Valley 8964ENC v.1.2.2 - Manual (Page 21)

8964ENC/-FS — Instruction Manual 21
Configuration
Also available with the 8964ENC-FS are the following freeze controls (one
must be selected from the five choices):
• AutoBlue – when AutoBlue is enabled on a channel, the output will
automatically freeze to a blue screen when the input signal is lost on
that channel.
• AutoFreeze – when AutoFreeze is enabled on a channel, the output will
automatically freeze on the last valid field when the input signal is lost
on that channel.
• Field 1 – manually freeze the output signal on field 1 of the last frame.
• Field 2 – manually freeze the output signal on field 2 of the last frame.
• Frame – manually freeze the output signal on the last frame.
Note A field freeze provides less resolution and no motion artifacts in the output.
In frame mode, the resolution is higher since both fields are present, but the
presentation of the two fields can cause motion artifacts.
Picture Enhancer Controls
The Picture Enhancer feature is standard on the 8964ENC and 8964ENC-FS
modules. This feature allows separate picture enhancement control on each
channel output.
Use the following controls for bypassing or disabling picture enhancement:
• Bypass – the Picture Enhancer circuitry can be bypassed to decrease the
amount of delay in the module if required.
• Disable – the Picture Enhancer process can be disabled, still routing the
signal through the Picture Enhancement circuitry.
When Picture enhancement is enabled, the following controls are available:
• Split screen – split the output screen to view the original video on the
left and the enhanced video on the right.
• Detail level – set the amount of picture enhancement detail based on the
split screen comparison.
• Overshoot protection – set the amount of clipping looking at a wave-
form monitor.
