D9859 Advanced Receiver Transcoder

The Cisco D9859 Advanced Receiver Transcoder extends the distribution op tions for
MPEG-4 Advanced Video Coding (AVC) high definition from solely MPEG-4
environments to existing MPEG-2 networks. Support for up to eight simultaneous
high-definition or standard-definition (SD) channels of decryption and transcoding
provides the advantage of density for locations requiring more than just a single
channel. The D9859 can provide up to 8 down-converted MPEG-2 standard
definition programs or MPEG-2 high-definition transcoded programs. Video and
two audio outputs are available for analog down-conversion for one of the
decrypted incoming MPEG-4 high-definition programs.

Digital Program Distribution

The Asynchronous Serial Interface (ASI) and MPEG over IP (MPEGoIP) transport
outputs are individually configurable and provide the capability of carrying up to
eight 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 program-specific information and service
information (PSI/SI) regeneration provides integration into a digital tier distribution
network for eight transcoded programs.
