[1] The number of valid bytes per line can be less for the sliced data format if standard not recognized (wrong
standard or poor input signal).
For each LCR value from 2 to 23 the data type can be programmed individually. LCR2 to
LCR23 refer to line numbers. The selection in LCR24 values is valid for the rest of the
corresponding field. The upper nibble contains the value for field 1 (odd), the lower nibble
for field 2 (even). The relationship between LCR values and line numbers can be adjusted
via VOFF[8:0] (located in subaddresses 5Bh, bit 4 and 5Ah, bits 7 to 0). The
recommended values are 07h for 50 Hz sources and 0Ah for 60 Hz sources, to
accommodate line number conventions as used for PAL, SECAM and NTSC standards
(see Table 11, Table 12, Table 13 and Table 14).
Some details about data types:
• Active video (data type 15) component YUV 4 : 2 : 2 signal, 720 active pixels per line.
Format and nominal levels are given in Figure 23 and Table 16.
• Test line (data type 6), is similar to decoded YUV data as in active video, with two
exceptions:
– vertical filter (chrominance comb filter for NTSC standards, PAL-phase-error
correction) within the chrominance processing is disabled
– peaking and chrominance trap are bypassed within the luminance processing, if
I2C-bus bit VBLB is set. This data type is defined for future enhancements; it could
be activated for lines containing standard test signals within the vertical blanking
period; currently the most sources do not contain test lines.
This data type is available only in lines with VREF = 0 (I2C-bus detail section,
see Table 46). Format and nominal levels are given in Figure 23 and Table 16.
• Raw samples (data type 7) oversampled CVBS-signal for Intercast applications; the
data rate is 27 MHz. The horizontal range is programmable via HSB7 to HSB0, HSS7
to HSS0 and HDEL1 and HDEL0 (see I2C-bus section subaddresses 06h, 07h and
10h and Table 34, Table 35 and Table 47). Format and nominal levels are given in
Figure 24 and Table 18.
• Sliced data (various standards, data types 0 to 5 and 8 to 14). The format is given in
Table 20.
