3.1 8VSB/QAM Receiver – Option 8701A
This card will receive a TS that is demodulated from an 8VSB signal or it will demodulate
a QAM64B or QAM256B RF input. With an 8VSB input, the card will tune to channels 2
– 69. With a QAM input, the card will tune to channels 2 – 134 in three cable frequency
bands (FCC, IRC, and HRC). The MRD 3187B will show a valid input if the following
conditions are met: the receiver equalizer and the FEC are locked. If the RF level is
lower than the “Low Warning Setting” or the MER is lower than the “Low MER Warning
Setting”, the red “Error” LED will illuminate on the front panel and there will be an error
recorded in the Error List.
3.2 Serial Transport Stream I/O (DVB-ASI/SMPTE 310M) –
Option 8702
This card will receive a TS from either a DVB-ASI input or a SMPTE 310M input. Only
one format may be selected at a time. For an ASI input, the bitrate of the TS must be
between 1.5 Mb/s and 160 Mb/s. For a SMPTE 310M input, the bitrate of the TS must be
19.392658 Mb/s. The selected input format will also be the output format. The 8702 card
can also be used as a TS output for any of the other input cards.
3.3 High Bit Rate ASI Input – Option 8703
This card will receive, up to a 160 Mb/s MPTS on ASI. This card is equipped with a
passive loop-through to allow the TS to be passed through the card without altering the
stream. The loop-through on this card cannot be used to output a TS from a different
input card. When the loop-through output is not in use it should be terminated with a 75
Ohm terminator.
3.4 Video Output (2 SD-SDI, 1 Composite) – Option
8704A/8704B
A standard definition video output card. It provides two mirrored serial digital (SMPTE
259M) outputs and one composite NTSC & PAL output. Four pairs of audio can be
embedded into the serial output on group 1 and 2. Closed captioning found within the
transport (608/708B) can be embedded into the serial video output. NTSC closed
caption, detected in the transport stream, can be inserted on line 21.
3.5 Video Output (2 HD-SDI, 1 RGBHV/YPbPr) – Option
8705/8705A
A high definition video output card. It provides two mirrored serial digital (SMPTE 292M)
outputs and one analog component video output (RGBHV or YPbPr). Four pairs of audio
can be embedded into the serial output on group 1 and 2. Closed captioning found within
the transport (608/708B) can be embedded into the serial video output.
3.6 Video Output (1 RGBHV/YPbPr, 1 Composite) – Option
8706A
An analog only video output card that can output either high definition or standard
definition formats. Two outputs are on the card: one BNC for composite (NTSC & PAL)
and one 15-pin D-sub for component (RGBHV or YPbPr). The card outputs an SD or HD
signal, one at a time. Closed caption (NTSC), detected in the transport stream, can be
inserted on line 21 of the composite (NTSC video) output.
3.7 Audio Output (Dolby E, AES Digital, Analog) – Option
8707A
This card allows the output of both Digital-AES and analog audio. Each digital audio
output can be set to either Raw or PCM. In Raw, the compressed audio for the selected
PID is passed through to the digital output. Typically this setting is used to pass-through
