S5D2650 Data Sheet
SCHCMP[3:0] value. The SCH signal changes every video line. The SCH for line 260 is held for the entire vertical
blanking period. By using the SCH signal for the same line from each field, proper field identification can be
determined. Figure 8 shows field identification values for SCHCMP[3:0]=0. It is important to note that the SCH
value is only valid for video signals that have a constant sync tip to color burst relationship. This is not the case with
consumer VCRs.
