Preliminary specication
PAL/NTSC/SECAM video decoder with adaptive PAL/NTSC
comb lter, VBI-data slicer and high performance scaler
SAA7114H
Table 108 Vertical input window length; register set A (9AH[7:0]; 9BH[3:0]) and B (CAH[7:0]; CBH[3:0])
Note
1. For trigger condition: STRC[1:0]90H[1:0] = 00; YO + YS > (number of input lines per field
2), will result in field
dropping. Other trigger conditions: YS > (number of input lines per field
2), will result in field dropping.

SUBADDRESSES 9CH TO 9FH
Table 109 Horizontal output window length; register set A (9CH[7:0]; 9DH[3:0]) and B (CCH[7:0]; CDH[3:0])
Notes
1. Reference for counting are luminance samples.
2. If the desired output length is greater than the number of scaled output pixels, the last scaled pixel is repeated.
Table 110 Vertical output window length; register set A (9EH[7:0]; 9FH[3:0]) and B (CEH[7:0]; CFH[3:0])
Note
1. If the desired output length is greater than the number of scaled output lines, the processing is cut.
