Scaler input format and configuration
source selection
Only if XRQT[83h[2]] = 1: scaler input source
reacts on SAA7114 request
Scaler input source is a continuous data
stream, which cannot be interrupted (must be
logic 1, if SAA7114 decoder part is source of
scaler or XRQT[83h[2]] = 0)
Scaler input source is data from decoder, data
type is provided according to
Scaler input source is Y-C
X port
Scaler input source is raw digital CVBS from
selected analog channel, for backward
compatibility only, further use is not
recommended
Scaler input source is raw digital CVBS (or
16-bit Y + C
active) from X port
SAV/EAV code bits D6 and D5 (F and V) may
change between SAV and EAV
SAV/EAV code bits D6 and D5 (F and V) are
synchronized to scalers output line start
SAV/EAV code bit D5 (V) and V gate on
pin IGPV as generated by the internal
processing; see
SAV/EAV code bit D5 (V) and V gate are
inverted
Scaler input format and configuration format control
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
X = don’t care.
X = don’t care.
FSC2 and FSC1 only to be used if X port input source does not provide chroma information for every input
line. X port input stream must contain dummy chroma bytes.
