Instruction manual

• Two video outputs. One for primary video and one for OSD video. Outputs either 525-

line NTSC/PAL M or 625-line PAL video formats, automatically matching based on the

programmer's input format. (No conversion is done between 525-line and 625-line

video.)

• VBI reinsertion on lines 10-22 supports data services such as North American

Broadcast Teletext, SID/AMOL I and II, and Closed Caption.

• Bypass video and audio inputs enable connections of analog signals to pass through the

unit and switch on or off when an alarm is triggered.

• Audio output consists of two stereo pairs. When the programmer provides multiple

audio choices, the audio pair can be selected. Programmers can tag audio channels with

a language so the receiver selects the audio material based on the specified language.

• MPEG-2 video and Dolby

Digital/MPEG-2 Layer I audio are employed for video

decode/decompression and audio compression respectively.

• Asynchronous Serial Interface (ASI) and Gig-E output for digital transport stream

output. Both can be configured to display a consistent PID mapping, regardless of

service input.

• Support for GigE Digital Storage Medium Command and Control (DSMCC)

• ASI input that decrypts and decodes the selected service.

• Ethernet Port for SNMP control and/or IP data pass through.

• DTMF output and relay control of tape machines and other ad insertion equipment.

• Four Form-C relays used for fault alarm indication or uplink control.

• Memory to recall the operating configuration when power sags or is removed.

• Security features include Motorola Mobility DigiCipher

II security technology. The DSR-

4550 does not require a TVPass

card to operate with security. In the unlikely event that

the code is broken, security can be renewed by inserting a card with a new code into the

receiver. Programmers may also utilize fingerprinting techniques to aid in piracy control.

• A two line, 40-character front panel with a time-out backlit Liquid Crystal Display (LCD).

• The DigiCipher II system allows for retune events in which a programmer sends

over-the-satellite messages to specified receivers to change the service they output for a

specified time period, then return to a specified service. During a retune event, the user

is locked out from editing this menu to ensure that the receiver does not get lost when

returning from the retune event.

• Isochronous data output.

• Disaster Recovery for L-Band signal loss.
