Note: This equipment has been tested and found to comply with the limits for a Class A digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in a commercial environment. This
equipment generates, uses and can radiate radio frequency energy and, if not installed and used in
accordance with the instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference in which case
the user will be required to correct the interference at his own expense. This digital apparatus does not
exceed the Class A limits of radio noise emissions from digital apparatus set out in the Radio
Interference Regulations of the Canadian Department of Communications.
MULTIPLEVOLTAGEEQUIPMENT:
The power cord included with your unit is for use with standard 125V AC supplies. If it is necessary to
operate the product in the U.S.A. with a 220V AC supply, then a UL-Listed power cord must be used and
the internal power supply jumper must be set. For countries outside the U.S.A. it is required to use a
power cord that complies with the electrical standards established by that country.

8. Accessories and Location: DO NOT place this product on an unstable cart, stand, tripod, bracket or
table. The product may fall causing serious injury and serious damage to the product. Use only with a
cart, stand, tripod, bracket or table that is recommended by the manufacturer or sold with the product.
Any mounting of the product should follow the manufacture’s instructions and should use a mounting
accessory recommended by the manufacturer.
9. Ventilation: DO NOT block or obstruct slots or openings in the equipment chassis. These openings
provide ventilation, ensure reliable operation of the equipment and protect it from overheating.
10. Environment: NEVER place this equipment near or over a radiator or heat register.
DO NOT operate this equipment in an area where proper ventilation is not provided.
11. Power Sources: ONLY operate this product from the type of power sources indicated in this manual
or on the appropriate marking label.
12. Grounding or Polarization: This product may be equipped with a polarized AC line plug (i.e., a
plug having one blade wider than the other). This plug will fit into the power outlet only one way. If
you are unable to fully insert the plug into the outlet, try reversing the plug. If the plug should still
fail to fit, contact an electrician to replace the obsolete outlet. This is a safety feature, DO NOT
attempt to defeat the purpose of this safety feature.
13. Power Cord Protection: Route power cords so that they are not likely to be walked on or pinched
by items placed on or against them. Pay particular attention to cords at plugs, outlets and the point
where they exit from the product.
14. Outdoor Antenna Grounding: If an outside antenna or cable system is to be connected to the
product, be sure the antenna or cable system is grounded as to provide some protection against
voltage surges and build-up static charges.
Section 810 of the National Electrical Code, ANSI/NFPA No. 70 provides information with respect to
proper grounding of the lead-in wire to an antenna discharge unit, size of grounding conductor,
location of antenna discharge unit, connection to grounding electrodes and requirements to grounding
electrodes.

Important Safeguards
DSR-4810 Operating Manual, Rev. B (4/09/00) v
15. Lightning: For added protection for this product during a lightning storm, or when the product is left

Introduction

CHAPTER 1
INTRODUCTIONINTRODUCTION
General Instrument DSR-4810 digital satellite receiver is an integrated
receiver/decoder (IRD) designed for broadcast networks and other commercial
satellite operations. It is simple to use as it allows the program provider to
perform many of the complex setup tasks. The receiver can then receive these
instructions from the satellite as part of the downloaded digital signal. It can be
configured to your exact needs using the front panel menus.
THE DSR-4810
The General Instrument DSR-4810 is hereinafter referred to as “unit.”
The General Instrument DSR-4810 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-4810 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 unit 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.
DSR-4810 has video synchronization capability across multiple DSR-4810
units. It 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.

Introduction
DSR-4810 Operating Manual, Rev. B (4/09/00) 2
KEY FEATURES
Each unit contains 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.
,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
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 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.
,Ability for network monitoring and control via a 10Base-T Ethernet
connection.Offer output of ASI, digital video (i.e., SMPTE259 with
embedded four-channel audio), digital audio, analog video, analog audio,
VBI lines and closed captionWHAT ARE VIRTUAL CHANNELS?
