5 Set the transcode manual GOP format value (User GOP). The transcoder
attempts to reuse information from the encoded bit stream to improve the video
quality of the transcoded stream. Amongst others, if the incoming GOP structure
is similar to that of an MPEG-2, it will reuse the frame allocations from the
incoming stream as long as GOP Control is set to I Frame Sync. If the
downstream transcoder does not support altering GOP structures, set the GOP
Control setting to User GOP (MN). This will also require the setting of the GOP
structure which is given as two numbers, where the first is the length of the GOP
and the second is the number of B-pictures per sub-GOP. The supported GOP
structures are 1.0, 12.2, 15.2, 24.2 and 30.2.

6 Enable or disable the 3:2 Pulldown.
7 Select the SD transcode channel Output Aspect Ratio. The options are 4:3 and
7 Select the SD transcode channel Output Aspect Ratio. The options are 4:3 and
16:9 (wide aspect ratio). The default is 4:3. Set it to the corresponding value.
8 Set the SD transcode channel Aspect Ratio Conversion. This is the conversion
that the transcoder will perform on the output signal for the picture to be
displayed correctly (i.e., to correspond to the aspect ratio of your TV) on your
TV, based on your selection. The options are: Auto, None, 16:9 L/B (letter box),
4:3 CCO, 14:9, 4:3 P/B (pillar box), 16:9 SCALE, or Auto AFD (Auto setting using
Active Format Descriptor). The default is set to Auto.
