SAF7118
Multistandard video decoder with adaptive comb filter
In
Table 13
and
Table 14
PHO is a usable common phase offset.
It should be noted that the equations of
Figure 40
produce an interpolated output, also for
the unscaled case, as the geometrical reference position for all conversions is the position
of the first line of the lower field; see
Table 13
.
If there is no need for UP-LO and LO-UP conversion and the input field ID is the reference
for the back-end operation, then it is UP-LO = UP-UP and LO-UP = LO-LO and the

phase shift (PHO + 16) that can be skipped. This case is listed in
Table 14
.
The SAF7118 supports 4 phase offset registers per task and component (luminance and
chrominance). The value of 20h represents a phase shift of one line.
The registers are assigned to the following events; e.g. subaddresses B8h to BBh:
B8h: 00 = input field ID 0, task status bit D0 (toggle status; see
Section 8.4.1.3
)
B9h: 01 = input field ID 0, task status bit D1
BAh: 10 = input field ID 1, task status bit D0
BBh: 11 = input field ID 1, task status bit D1
Depending on the input signal (interlaced or non-interlaced) and the task processing
50 Hz or field reduced processing with one or two tasks (see examples in
Section 8.4.1.3
), other combinations may also be possible, but the basic equations are the
same.
