Product data sheet
Table 8:
The generation of the H-bit and consequently the timing of SAV/EAV corresponds to the
selected data format. H = 0 during active data region. For all data formats excluding data
type 7 (raw data), the length of the active data region is 1440 LLC. For the
Y-C
contains valid data; see
The sliced data stream (various standards, data types 0 to 5 and 8 to 14; see
contains also invalid cycles marked as 00h.
The length of the raw data region (data type 7) is programmable via HSB7 to HSB0 and
HSS7 to HSS0 (subaddresses 06h and 07h; see
During horizontal blanking period between EAV and SAV the ITU-blanking code sequence
‘-80-10-80-10-...’ is transmitted.
The position of the F-bit is constant according to ITU-R BT 656; see
The V-bit can be generated in four different ways (see
OFTS1 and OFTS0 (subaddress 10h, bits 7 and 6), VRLN (subaddress 10h, bit 3) and
LCR2 to LCR24 (subaddresses 41h to 57h).
F and V bits change synchronously with the EAV code.
