Description

The PowerVu Model D9858 Advanced Receiver Transcoder provides the ability to deliver MPEG-4 HD services to MPEG-2 CATV headends. The Model D9858 receiver extends the distribution options for MPEG-4 AVC HD from solely MPEG-4 environments to existing MPEG-2 networks. Support for simultaneous dual-channel decryption and transcoding provides the advantage of density for locations requiring more then just a single channel. The D9858 can be utilized to provide a down-converted Standard Definition MPEG-2 program instead of one or both of the available HD transcoded programs. Video and two audio outputs are available for analog down-conversion for one of the decrypted incoming MPEG-4 HD programs.

Digital Program Distribution

The ASI and MPEGoIP transport outputs are individually configurable and provide the capability of carrying up to two decrypted transcoded programs for digital tier distribution. This helps the compressed video programs to be efficiently distributed to subscribers equipped with digital set-top boxes. Digital audio passthrough is synchronized to the transcoded program output. Compliant PSI/SI regeneration provides integration into a digital tier distribution network for two transcoded programs.

Digital Program Mapping

Digital Program Mapping allows programmers to "transparently" substitute programs at the uplink. It maintains predictable and compliant transport output during service replacement, Network Information Table (NIT) retune, channel changes, including force tunes. This feature remaps the PID information from the primary service to an alternate service allowing downstream devices to continue to operate without headend operator intervention. This helps ensure availability of alternate programming in the digital tier.

Digital Ad-insertion

Digital Program Insertion (DPI) information is available along with the video and audio PIDs (Packet Identifiers) for external ad insertion in compressed digital format on both transcoded programs.
