Output Formatter
The Output Formatter of the decoder part contains the ITU 656 8 bit / 10 bit formatter for the expansion port (X-Port) data
output (XPD[7:0], XRH, XRV) including the selection of the reference signals for the RT port (RTCO, RTS0 and RTS1)
and the expansion port (XRH, XRV and XDQ) (for a detailed description see Section 9.4.1) as well as the control circuitry
for the signals needed for the internal paths to the scaler and data slicer part.
This control circuitry requests decoded video data (Y-C
-C
4 : 2 : 2) or raw data from the combfilter decoder output to
user controlled by the line control registers LCR2 to LCR24 (see also Chapter 16; subaddresses 41H to 57H).
Each of the registers LCR2 to LCR23 defines a data type to be decoded in the associated line; i.e.: the VBI data type
can be set independently for each of the lines. Therefore LCR2 to LCR23 refer to line numbers. The selection in LCR24
values is valid for the rest of the corresponding field. The upper nibble of each of the 23 LCR registers 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 VOFF8 to VOFF0, located in subaddresses 5BH (bit 4) and 5AH (bits 7 to 0), FOFF subaddress 5BH
(bit D7) and VEP subaddress 5BH (bit D5). The recommended values are VOFF[8:0] = 03H for 50 Hz sources (with
FOFF = 0) and VOFF[8:0] = 06H for 60 Hz sources (with FOFF = 1), to accommodate line number conventions as used
for PAL, SECAM and NTSC standards; see Tables 7 to 10.
N
ote
: The line counting scheme for 60 Hz standards, with VOFF = 0x06, as mentioned in Fig.23, table 7 and table 8,
leads the VBI slicer to take the old field ID as reference for it’s field processing. For consistent ID interpretation the VOFF
value need to be set to 0x03.
