• 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.
