Introduction
1DSR-4800 Operating Manual
CHAPTER 1
INTRODUCTION
General Instrument DSR-4800 digital satellite receivers are integrated
receiver/decoders (IRD) designed for broadcast networks, cable systems and
other commercial satellite operations. They are simple to use as they allow the
program provider to perform many of the complex setup tasks. The receivers can
then receive these instructions from the satellite as part of the downloaded digital
signal. They can be configured to your exact needs using the front panel menus.
WHAT ARE VIRTUAL CHANNELS?
It is important to understand how virtual channels work before using the
front panel menus.
When you manually tune to a transponder and select a programmer’s VCT
number and channel designation, the receiver will download the VCTs
available on that transponder. For example, a programmer may have one
VCT for his consumer network and a different VCT for his commercial
customers. You can accept several VCTs in memory. When you download
more tables, the table that is not used for the longest period of time is
discarded first. The number of VCTs retained depends upon table size, but
there is typically room for five or more commercial network tables.
The DigiCipher®II network and its VCT can be limited to part of one
transponder, one entire transponder, many transponders on one satellite or
many transponders on several satellites. The units have four antenna satellite
input ports that can connect to antennas aimed at two different satellites.
Since the VCTs include satellite and transponder (frequency) information,
the receiver will change satellite and transponder as needed when the virtual
channel on the front panel is changed. The receiver will give an error
message on the front panel LCD if the VCTs prompt it to change to a
satellite/transponder that it cannot find on the input ports.
At most, each virtual channel has only one video data stream. Some virtual
channels have audio or data-only services. The virtual channel may have
many audio elements, and they are selected by language: English (stereo
implied) and French-Portuguese (mono-mono) are just a sample of the 256
possibilities. The IRDs have enough memory to accept a download of 64
languages in a network. In the case of mono-mono (French-Portuguese for
example), the left output is the first mono (French), and the right output is the
second mono (Portuguese). If you specify a language that is not available, the
audio defaults to the first in the VCT list–usually selected by the programmer
because it matches the video lip movements.

CHAPTER 2
THE DSR-4800 SERIES
The General Instrument DSR-4800 series of digital satellite receivers
includes the DSR-4800, DSR-4810 and the DSR-4850. The aforementioned
products are hereinafter referred to as “unit.”
DSR integrated receiver/decoders are designed for broadcasters and other
professional, contribution-quality commercial satellite operations. They can
be very simple to use as they allow the program provider to perform many of
the complex setup tasks. The receivers can receive instructions from the
satellite as part of the downloaded digital signal, or you can configure it to
your exact needs using the extensive front panel menus.
All units contain the following key features:
,The microprocessors and memory built into each unit decodes and
decompresses the MPEG-2 video, audio, data and other information in
the signal. This significantly decreases the amount of information to be
transmitted thereby reducing bandwidth requirements. Broadcasters and
programmers can transmit on one carrier any number of channels,
limited only by the material transmitted and their particular network
needs.
,Delivery of the best possible video and audio quality by using forward
error correction (FEC) techniques that make allowances for poor signal
quality. FEC determines which information is corrupted, then corrects it.
As a result, the digital signal remains clear until the signal quality
degrades to a level where FEC can no longer restore the information.
This threshold is below an analog receivers’ ability to provide
recognizable video.
,Based on MPEG-2 standards, we use virtual channel mapping to select
the desired video, audio and other data streams out of the overall
transmission.
,Virtual channel information can be determined over the satellite at any
time, allowing for dynamic changes in the network without requiring you
to reconfigure the receiver.
,Automatically handles fixed, limited-statistical and full-statistical
multiplexing to provide the best video performance.
,For audio compression, we use the Dolby®Digital compression
techniques chosen by the North American Grand Alliance for High
Definition Television and for the newest digital videodisk systems. The

The DSR-4800 Series
3DSR-4800 Operating Manual
receiver automatically adjusts to the compression rate used for the audio.
In the DVB mode, the unit is capable of processing DVB Musicam
audio.
,Non-volatile memory to indefinitely recall the operating configuration
when power fluctuates, is interrupted or removed altogether.
,Security features, including General Instrument’s proven security
system. Even though the unit does not require a TvPass™ Card to
operate with security, in the unlikely event that the code is compromised,
security can be renewed by simply inserting a card with a new code into
the receiver.
,A low profile, single rack unit design – only 1.75” EIA rack space.
,Able to process and provide the broadcast engineer with a 4:2:2 Studio
Profile @ Main Level digital video output from a DigiCipher®II or DVB
signal.
,The front panel display and edit/select control are formatted to provide
optimum resolution, execution and the most effective display of
information necessary for operation.
,Controllable or status monitored via either of two separate data interfaces
or by way of satellite network control.
,The unit’s EIA232/485 rear panel control interface can be configured to
directly plug and play with your existing network control system.
,A complete set of extended commands allow for remote control of all the
receiver’s additional controls and functions.
,Ability for network monitoring and control via a 10Base-T Ethernet
connection.
,All units offer output of ASI, digital video (i.e., SMPTE259 with
embedded four-channel audio), digital audio, analog video, analog audio,
VBI lines and closed caption.
THE DSR-4800
The General Instrument DSR-4800 receives both HD and SD signals. Both
HD and SD streams are reprocessed to the Digital Video Broadcast
Asynchronous Serial Interface format at 270 Mbps. The ASI signal is output
through a BNC connector.
SD transport streams can be processed at 4:2:2 P/ML and 4:2:0 MP/ML
decompression.
The unit receives QPSK modulated signals at L-band frequencies of 950 to
2150 MHz through one of four input ports.

The DSR-4800 Series
DSR-4800 Operating Manual 4
The DSR-4800 performs demodulation and FEC decoding of all standard
DigiCipher®II symbol and convolutional coding rates, at information rates
up to 40.46 Mbps. It also performs demodulation and FEC decoding of all
standard DVB convolutional coding rates, at information rates of 3.25–45
Msps. Within the resulting transport stream, a single DigiCipher®II service
designated by the user can be decrypted.
The DSR-4800 will automatically tune to of four L-band inputs based on the
Virtual Channel Tables sent from the UCS. The unit will use the Virtual
Channel Tables for tuning between services.
THE DSR-4801
The General Instrument DSR-4801 is a more economical version of the full-
featured DSR-4800 designed for the studio monitoring, video processing and
satellite turnaround markets requiring 4:2:2 digital video output.
DSR-4801 receives both HD and SD signals. SD transport streams can be
processed at 4:2:2 P/ML and 4:2:0 MP/ML decompression.
The unit receives QPSK modulated signals at L-band frequencies of 950 to
2150 MHz through one of four input ports.
The DSR-4801 performs demodulation and FEC decoding of all standard
DigiCipher®II symbol and convolutional coding rates, at information rates
up to 40.46 Mbps. It also performs demodulation and FEC decoding of all
standard DVB convolutional coding rates, at information rates of 3.25–45
Mbps. Within the resulting transport stream, a single DigiCipher®II service
designated by the user can be decrypted.
The DSR-4801 will automatically tune to of four L-band inputs based on the
Virtual Channel Tables sent from the UCS. The unit will use the Virtual
Channel Tables for tuning between services.
The lack of a full-feature VBI board, ASI output and Ethernet control
distinguishes it from the DSR-4850.
THE DSR-4810
The General Instrument DSR-4810 includes all features of the DSR-4800
with the addition of video synchronization capability across multiple DSR-
4810 units. The unit will accept a primary and secondary video input
reference and synchronize the output audio and video to one of those
references. It will also provide a video output reference for other units to use
as a synchronization reference.

The DSR-4800 Series
5DSR-4800 Operating Manual
THE DSR-4850
The General Instrument DSR-4850 includes all features of the DSR-4800
with the following variance: An ASI input option has been installed in place
of the satellite QPSK tuner allowing the DSR-4850 to function as a decoder.
The DSR-4850 receives the MPEG-2 transport stream in DVB ASI format
through a BNC connector to an ASI input module. Once the ASI transport
stream is received either from a DSR-4800 or DSR-4810 unit, multiple DSR-
4850 units can be looped together.
DCII HD transport streams are processed to decrypt a service selected by the
user. The resulting transport stream is output in ASI format.
SD transport streams are processed to extract, decrypt and decompress a
service selected by the user.
The DSR-4850 will use the Virtual Channel Tables from the UCS for tuning
between common services.
