SAA7118 Datasheet, PDF (148/169 Pages) NXP Semiconductors – Multistandard video decoder with adaptive comb filter and component video input

Philips Semiconductors
Multistandard video decoder with adaptive
comb filter and component video input
Preliminary specification
SAA7118
Table 110 Task handling control; register set A [90H[2:0]] and B [C0H[2:0]]
X = don’t care.
EVENT HANDLER CONTROL
Event handler triggers immediately after finishing a task
Event handler triggers with next V-sync
Event handler triggers with field ID = 0
Event handler triggers with field ID = 1
If active task is finished, handling is taken over by the next task
Active task is repeated once, before handling is taken over by the next task

SCALER INPUT FORMAT AND CONFIGURATION SOURCE
SELECTION
Only if XRQT[83H[2]] = 1: scaler input source reacts on
SAA7118 request
Scaler input source is a continuous data stream, which cannot
be interrupted (must be logic 1, if SAA7118 decoder part is
source of scaler or XRQT[83H[2]] = 0)
Scaler input source is data from decoder, data type is
provided according to Table 15
Scaler input source is Y-C_B-C_R data from 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_B-C_R, if
no 16-bit outputs are 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 Fig.43
SAV/EAV code bit D5 (V) and V-gate are inverted
