Pass Second Audio: if this box is checked, a secondary audio PID is passed though the
transcoder if present. Secondary audio can only be passed from input to output;
transcoding is not available.
•
Program Name: this setting controls how the program name is handled through the
transcoder. The options are:
o
Pass-through: if this option is selected, the program name is retained through the
transcoding process, as long as the input program contains a valid name. If the
input program does not have a name (i.e., no SDT or VCT), then there will be no
name for the transcoded program.
o
Override: if this option is selected, the incoming program name is ignored, and a
new program name can be assigned to the transcoded content. New fields become
available:
Program Name: enter the desired program name.
Provider Name: enter the desired provider name.
Service Type: this configures the service type, as per ETSI EN 300 468
section 6.2.32. It is recommended to leave this setting on auto-select,
which directs the BBG-1090-TRX-MPEG to choose the appropriate
service type depending on the compression standard and bit rate.
Otherwise, the following types can be selected:
•
digital television service: used for MPEG-2 SD.
•
MPEG-2 HD digital television service: used for MPEG-2 HD.
•
advanced codec SD digital television service: used for H.264 SD.
•
advanced codec HD digital television service: used for H.264
HD.
•
Interlace Mode: this control selects the output interlace mode. It has the following
options:
o
Auto: automatically set the interlace mode.
o
Interlaced: convert the content to interlaced mode.
o
Progressive: convert the content to progressive mode.
If the Interlaced or Progressive modes are selected, the Output Frame Rate setting
(see below) is forced to Custom Frame Rate, and the actual output frame rate must be
specified.
•
MBAFF: this parameter controls the use of the H.264 MacroBlock-Adaptive
Frame/Field coding tool. This tool allows a single frame to be encoded partially in
progressive mode and partially in interlaced mode, depending on the content. Use of this
tool improves video quality for interlaced content; however, some low-end decoders may
not support it. The following options are available:
o
Auto: automatically set the MBAFF mode.
