SAF7118
Multistandard video decoder with adaptive comb filter
Workaround
:
It should be avoided to use the detected odd/even information whenever it cannot be
assured that the input signal is of stable time base.
19.6 Issue 6: Slicing of MOJI VBI data leads to unexpected results
Background (how it should work)
:
SAF7118 incorporates a versatile VBI data slicer, for various data types, including MOJI.
The sliced data is provided as video stream at the image port. The entire VBI data packet
counts 56 bytes, including the leading SAV and trailing EAV sequence. The detailed
values for SAV and EAV codes depend on odd/even field identification and on some
programmable device settings. SAV is followed by an internal 4-byte header, indicating
actual data type and line number in byte IDI1 and IDI2, among other status information.
The data packet is closed by an EAV sequence, preceded by byte count and check sum
byte. To maintain a constant and fix length of the VBI data packets, the remaining space
between actual sliced data and check sum is filled up with stuffing bytes of value A0.
For MOJI data standard (35 sliced data bytes are generated), there should be no general
difference in data handling compared to e.g. WST625.
Anomaly description
:
Under certain conditions, erroneous and meaningless bytes are inserted between internal
header and actual sliced data. These faulty bytes are mostly logic 0, but can be different
values, too (see
Figure 99
).
The problem might also occur with VBI data standards of similar data rate, e.g. NABTS.
