comb filter, VBI data slicer and high performance scaler
SAA7114
In Tables 13 and 14 PHO is a usable common phase
offset.
It should be noted that the equations of Fig.30 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
1
2
line phase shift (PHO + 16) that can be
skipped. This case is listed in Table 14.
The SAA7114 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 8.3.1.3)
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 8.3.1.3), other combinations may also be
possible, but the basic equations are the same.
