the Dolby AC-3 compressed digital signal. When the digital audio output is set to PCM,
two-channel linear coded PCM AES/EBU audio is output to the digital output. The
analog output provides two-channel (L, R) decoded analog audio from the selected
audio processor. The two audio processors on the decoder board, feeding the two digital
outputs, can process or decode Dolby AC-3, MPEG Layer 1, or MPEG Layer 2 formats.
The audio processor will self-sense which type of audio is in the TS. The 8707A also has
a Dolby E parsing feature.
3.8 Video Output (2 HD/SD-SDI, 1 RGBHV/YPbPr/Composite) –
Option 8708
A versatile video output card. It provides two user selectable serial digital (SMPTE
259M, or SMPTE 292M) outputs and one component RGBHV or YPbPr/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.
3.9 Dual Input DVB-S/DVB-S2 Receiver – Option 8710/8710A
This card will input a satellite L-band (950 MHz – 2150 MHz) signal for demodulation of
KU-band or C-band DVB-S QPSK signals or DVB-S2 QPSK/8PSK signals. The symbol
rate ranges from 1 MSym/s to 45 MSym/s for DVB-S and 1-30 MSym/s for DVB-S2. This
card does not provide any power to the dish LNB. The “Input” LED will only illuminate if
the card detects frequency, symbol rate, FEC lock (Carrier Lock), and TS sync (Sync
Lock). The card provides A and B inputs, which may be independently configured, but
only one may be active at a time.
3.10 Dual Input ASM Receiver – Option 8711
This card will input a satellite L-band (950 MHz – 2150 MHz) signal for demodulation of
KU-band, C-band, or X-band DVB-QPSK, 8PSK, or Adv-QPSK signals. All these modes
are available using Turbo Coded forward error correction. The DVB-QPSK mode also
supports legacy DVB FEC. The symbol rate ranges from 0.256 MSym/s to 30 MSym/s
for all modulation types. This card does not provide any power to the dish LNB. The
“Input” LED will only illuminate if the card detects frequency, symbol rate, FEC lock
(Carrier Lock), and TS sync (Sync Lock). The card provides A and B inputs, which may
be independently configured, but only one may be active at a time.
3.11 Video Output (2 HD/SD-SDI, 1 RGBHV/YPbPr/Comp) –
Option 8712
A versatile video output card. It provides two user selectable serial digital (SMPTE
259M, or SMPTE 292M) outputs and one component RGBHV or YPbPr/Composite
NTSC & PAL output. Eight pairs of audio can be embedded into the serial output on
group 1, 2, 3 and 4. 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.
Note: This card requires the 8733 decoder board.
3.12 GPIO Module – Option 8713
This module is considered a global unit option. In other words, the inputs and outputs of
a single installed module can be accessed by functions associated with general system
features, or RDS specific features in any unit configuration. Only one GPIO module can
be installed in a unit.
3.13 Dual Input COFDM Receiver – Option 8715
This card will input a (49 – 861 MHz) COFDM signal for use in electronic news gathering
(U.S.) or any COFDM Terrestrial Broadcast (DVB-T, European) applications. The card
