Description
General Instrument DSR4400 INTL 1550 MPEG2 Digital Satellite Receiver 081193-001
The General Instrument DSR4400 INTL 1550 is a professional-grade MPEG-2 Integrated Receiver/Decoder (IRD) designed for cable television headend and satellite distribution applications. It receives L-Band satellite signals and decodes MPEG-2 compressed digital video and audio, supporting DigiCipher conditional access and decryption. Built in the United States by General Instrument's Cable/Home Communications division, it is housed in a 2U rackmount chassis suitable for headend equipment racks.

Applications
The DSR4400 was designed for professional cable television and satellite headend facilities, where it served as the receive-and-decode endpoint for DigiCipher-encrypted MPEG-2 digital satellite programming. General Instrument's DigiCipher technology was one of the foundational conditional access systems used in North American digital cable and satellite distribution in the mid-to-late 1990s — it was the precursor technology to what became the DCII (DigiCipher II) standard widely deployed by cable operators. Units like the DSR4400 were rack-mounted in headend equipment rooms and used to pull down individual programming channels from C-band or Ku-band satellite transponders, decode the MPEG-2 stream, and feed baseband audio and video to modulators or other downstream headend gear. The INTL 1550 variant supports international power input (120–240VAC), making it suitable for headend deployments outside North America as well. Today these units are sought by vintage broadcast collectors, satellite hobbyists, and facilities maintaining legacy headend infrastructure.
This General Instrument DSR4400 INTL 1550 MPEG2 Digital Satellite Receiver has been inspected and is in good used condition. The chassis, front panel, and controls show normal wear consistent with prior rack deployment. The LCD display, navigation keypad, and status LEDs are all present and intact.
