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) specified 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.
