2.14.2. Sliced VBI Data
The sliced data mode is enabled with bit[1] of FP-RAM
0x138 (vbimode). This mode uses the integrated data
slicer and delivers decoded data samples to the output
ports.
The data slicer provides data packets of a constant size
(filled with dummy bytes). The data packets have a de-
fault size of 64 bytes. To reduce the data rate for text sys-
tems with a smaller number of data bytes, the packet
size can be reduced via FP-RAM 0x139.
During lines within the VBI-window, specified by the user
settings in the corresponding Load-Table, the VPX inter-
nally multiplexes the data slicer packets onto the lumi-
nance and chrominance outputs. Since in the 8-bit out-
put modes (ITU-R656, BStream), the values 0, 254 and
255 are protected, each slicer sample is separated into
two nibbles for transmission. Table 2
–
13 shows the im-
plemented data formats.
In each path, one nibble is transmitted twice. The LSB
is inverted for odd parity. This assures that the values 0
and 255 will not occur (for the detection of embedded
syncs). In the mode with embedded timing event codes,
chrominance data will be limited additionally. No signifi-
cant information will be lost since only bit[0] and bit[1] will
be modified. Figure 2
–
39 shows the timing of data and
reference signals in this mode.

The splitting described above can be disabled by setting
bit[6] in the
‘
format_select
’
register. In this case, the
sliced samples will be transmitted in the luminance path
only. To avoid modification of valid data, the limitation of
luminance data in the 8-bit output modes should be sup-
pressed with bit[8] in the same register (note that lumi-
nance codes will not be protected).
