Decoder output formatter
The output interface block of the decoder part contains the
ITU 656formatterfortheexpansionportdataoutputXPD7
to XPD0 (for a detailed description see Section 9.4.1) and
the control circuit for the signals needed for the internal
paths to the scaler and data slicer part. It also controls the
selection of the reference signals for the RT port (RTCO,
RTS0 and RTS1) and the expansion port (XRH, XRV
and XDQ).
The generation of the decoder data type control signals
SET_RAW and SET VBI is also done within this block.
These signals are decoded from the requested data type
for the scaler input and/or the data slicer, selectable by the
control registers LCR2 to LCR24 (see also Chapter 15;
subaddresses 41H to 57H).
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 VOFF8 to VOFF0, located in
subaddresses 5BH (bit D4) and 5AH (bits D7 to D0) and
FOFF subaddress 5BH (bit D7). 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 5 to 8.
