Video Decoder Mode
– The
Video Decoder Mode
parameter defines the mode of the analog
interface. The analog interface can be TV, DVD or VCR.
The available options are:
❑
TV
– Expects to have a stable and jitter-free video input signal. Thus, the required TBC
(time-base corrector) algorithm is less aggressive. (Default)
❑
DVD
– Expects to have a stable and jitter-free video input signal but the video input may
have some signals added by DVD to prevent recording on VTRs. This mode cleans the
video input signal from the DVD signals.
❑
VCR
– Expects to have low quality video signal (synchronization time is jittery). Thus, the
TBC algorithm invoked is the most aggressive.
■
NTSC Setup
– The
NTSC Setup
parameter enables the NTSC setup level option. It refers to the
black level of the analog video signal.
NOTE:
Setup level is relevant only for NTSC format.
The available options are:
❑
On
– Black level is higher than Blank level. (Default)
❑
Off
– Black level is equal to Blank level.
■
Color Coring
– The
Color Coring
parameter decreases the color error near the black level.
The available options are:
❑
Disable (Default)
❑
Level 1
❑
Level 2
❑
Level 3
■
Y/C Delay
– The
Y/C Delay
parameter controls the chrominance and luminance delay,
measured in pixels. The parameter displays the current delay value and enables the selection of
the Y to C delay for the component video (active only when the component input interface is
provided).
Luminance-to-chrominance delay inequality is the difference between the time it takes the
chrominance portions of the signal to pass through the system and the time it takes the
luminance portion of the signal to pass through the system. Picture effects caused by
luminance-to-chrominance delay errors include color smearing or bleeding, particularly at
image edges.
The available options are:
❑
No Delay (Default)
❑
+0.5 pixel
❑
-0.5 pixel
