Input is Y-C
Input is Y-C
Chroma is provided every line, default
Chroma is provided every 2nd line
Chroma is provided every 3rd line
Chroma is provided every 4th line
Rising edge of XRV input and decoder V123 is vertical reference
Falling edge of XRV input and decoder V123 is vertical reference
XRV is a V-sync or V gate signal
XRV is a frame sync, V pulses are generated internally on both edges of
FS input
X port field ID is state of XRH at reference edge on XRV (defined by
XFDV)
Field ID (decoder and X port field ID) is inverted
Reference edge for field detection is falling edge of XRV
Reference edge for field detection is rising edge of XRV
PC-CODEC
input stream must contain dummy chroma bytes.
