Typical DISH Network HD Transcoder System Overview
The LG HCS7720 DISH Network HD transcoder represents a single-program MPEG-4 to
MPEG-2 HDTV solution for commercial and institutional MATV systems (hotels, hospitals,
etc.).
A typical DISH Network HD Transcoder System includes:
• One HCS7720 DISH Network HD transcoder card for each HD program offered in the
facility’s MATV system.
• A CodePlus series card frame (Example: HCS6150R) specied for the HCS7720.
• A DISH Network 3-LNB dish antenna system, required for MPEG-4 support and reception. *
• A DISH Network ViP 222k satellite receiver for each transcoder card. (Note that ViP 222
satellite receivers are not supported with HCS7720 transcoder cards.) *
• A QAM or VSB modulator with ASI input for each transcoder or an LG CodePlus series
HCS6320 MUX/MOD feature card. Multiplexers can be used in front of the modulator if
multiple programs are desired and 256-QAM is used. *
• (For each modulator, if applicable) An upconverter compatible with digital modulation. *
• A 19-inch rack for mounting. *
• Miscellaneous cables and installation hardware (see also setup information on page 6). *
The integrated elements of the DISH Network HD Transcoder System:
• Receive a selected HD program from DISH Network service.
• Transcode the received digital video and audio stream to an MPEG-2 compatible transport
stream.
• Encrypt the transcoded digital data stream.
• Modulate the stream in QAM or VSB.
• Upconvert the modulated, encrypted transport stream to an RF channel.
A Pro:Idiom compatible television with a QAM/VSB tuner is required to view premium HD
content. The HCS7720 converts the DISH Network encryption to Pro:Idiom encryption; thus,
a proper session ID must be set at the TV in order for Pro:Idiom decryption to be enabled.
LG’s Pay-Per-View (PPV) partners can set up this session through their interface. LG’s
Free-To-Guest (FTG) Mode of operation also enables Pro:Idiom decryption.
Note: The RF output from the Transcoder System can be combined with other channels in
the site’s distribution grid.

System Setup
Typical HCS7720 System Installation
(see also Typical Setup Flow Charts on page 14)
1. Verify that the ViP 222k satellite receiver is set up and functioning (i.e., check that the
ViP 222k is connected to an NTSC monitor [for tuning purposes], that it is powered up,
that initialization is complete, and that the NTSC monitor is displaying the default channel
properly—refer to the ViP 222k documentation).
Note: 720p display resolution is required for standard HCS7720 operation.
Before you continue, use the ViP 222k menu system (Setup > HDTV Setup > TV
Type) to ensure the resolution is set to 720p.
2. Make sure the ViP 222k is in Single Mode, and then tune the receiver to the desired
MPEG-4 HD channel using the controls on the front panel or the IR remote control.
3. Connect the supplied CAT5E shielded cable between the X-PORT LINK port on the
HCS7720 and the ETHERNET port on the ViP 222k. Then, connect the supplied HDMI
cable between the HDMI IN port on the HCS7720 and the HDMI (Out) port on the ViP 222k.
Note: Once you make the connections between the ViP 222k and the HCS7720, ViP 222k
remote control functionality will be disabled by default. If required, you can enable remote
control functionality using the “Enable/Disable RC Functions” option described on page 23
(under “Satellite Receiver Menu Commands”). It is also possible to set/change the satellite
receiver channel via the HCS7720 Satellite Receiver Menu.
4. Perform one of the following per your installation:
• If the HCS7720 will be used with an external modulator and upconverter, connect a 75
ohm BNC-to-BNC coaxial cable between ASI OUT on the HCS7720 and ASI IN on the
modulator. Then, continue with step 5.
Note: The BNC cable must be less than 30 feet (9.2 meters) in length.
• If the HCS7720 will be used with an HCS6320 MUX/MOD feature card (internal modulator
and upconverter functionality), the cable to the ASI OUT port will not be required. Refer to
the HCS6320 CodePlus™ Series MUX/MOD Feature Card Installation & Setup Guide
for further instruction before you continue this setup procedure.
5. For an installation with an external modulator and upconverter: Connect an RF coaxial
cable between IF OUT on the modulator and IF IN on the upconverter, and then check the
modulator and upconverter for correct settings (QAM type, channel number, etc.).
6. Repeat steps 1 to 5 for each of the ViP 222k/transcoder pairs.
7. Plug in the power to the CodePlus card frame containing the newly installed HCS7720
card(s). The green STATUS LED will blink approximately once every second while the
HCS7720 card boots up. The boot-up process for an HCS7720 may take up to two
minutes, and there is no ASI output (if applicable) during boot-up.
When the boot-up is complete, both the green STATUS LED and the amber LED at the
base of the X-PORT LINK connector will be lit continuously.

Command >
Install a Pro:Idiom Key
The Pro:Idiom encrypter built into the HCS7720 contains a default encryption key. When first
installed, the HCS7720 will use this key to encrypt content. This command enables you to
change the encryption key, if necessary.
Note: In order for a Pro:Idiom encrypted channel to be displayed, the receiver
must contain a Pro:Idiom decrypter, and the receiver must be congured to allow
decryption of the desired channel.
Note: The process of updating the encryption key will synchronize the decryption
key in any receiver tuned to this card’s output. If the target receiver is turned off or
viewing a different card, the synchronization will not occur, and the output will be
scrambled. Ensure that all encrypters and decrypters in a system are synchronized
to the same key.
1. Confirm the directory location of the Pro:Idiom key (.hex) file.
2. Connect a PC to the HCS7720 Service Port, and access the Main Menu as described on
the previous page.
3. At the Main Menu Command > prompt, type the menu command that corresponds to the
Install PI Key option and press Enter.
4. At the Setup PI key. Continue (y/n)? prompt, type y and press Enter to
continue.
5. The system will request a key file. Transfer the new Pro:Idiom key file using Xmodem
protocol.
For example, in HyperTerminal, select Transfer and then Send File.... In the Send File
window, enter or select the appropriate Pro:Idiom key file in the Filename field, and select
Xmodem in the Protocol field.
The system will print out the result of the update process. Note that the new key will be stored
in non-volatile storage regardless of process results.

TFTP Transfer
The HCS7720 must be connected to an IP network for a TFTP transfer. TFTP transfer
also requires that you set up a TFTP server on the PC. The TFTP server must be on
subnet 192.168.0.x, where x can be any number between 0 and 255, except 200.
a) Connect an Ethernet cable between the HCS7720 X-Port Link and the PC. For this
purpose, you can disconnect the satellite receiver end of the ViP 222k/HCS7720
Ethernet cable, and connect it to the PC.
b) Make sure the firmware update files are available on the same machine as the TFTP
server. Then, set up the TFTP server, and point to the directory in which the firmware
update files are located.
Note the name of the configuration file; you will need it to initiate the transfer.
c) At the menu > prompt, type 2 and press Enter to select the TFTP Transfer option.

View MUX Bitrate Data
Bitrate data is useful for system monitoring and troubleshooting purposes. Use the following
procedure to view MUX bitrate data.
1. Connect a PC to the HCS7720 Service Port, and access the Main Menu as described on
page 15.
2. At the Main Menu Command > prompt, type the menu command that corresponds to the
Read MUX Bitrates option and press Enter.
MUX bitrate data is displayed in millions of bits per second (Mbit/s), for example:
HDMI Input Bitrate: 14.120 Mbit/s (raw 14.120 Mbit/s)
Ethernet Input Bitrate: 0 (raw 9.210 Mbit/s)
Data Output Bitrate: 16.881 Mbit/s
Total Output Bitrate: 19.396 Mbit/s
The bitrate output data indicates the following:
• HDMI Input Bitrate: The data bitrate of the HDMI input. A low or zero value indicates an
HDMI input malfunction.
• Ethernet Input Bitrate: The data bitrate of the Ethernet input. The rst value will be zero,
and the raw value should be non-zero. A raw value of zero indicates an Ethernet input
malfunction.
• Data Output Bitrate: The non-null data bitrate output on the ASI port (if applicable).
If the HDMI Input bitrate is non-zero, a Data Output bitrate of zero indicates an indeterminate
error. In this case, refer to the troubleshooting information in this document, and troubleshoot
the satellite STB and/or the transcoder card.
• Total Output Bitrate: Under standard operating conditions, this value should be nominally
19.396 Mbit/s. If the bitrate differs from this value by more than 1%, troubleshoot the satellite
STB and/or the transcoder card (see troubleshooting information in this document), and then
if necessary, verify that the card frame chassis is properly installed.
