Chapter 1 Introduction

D9858 Advanced Receiver Transcoder

The D9858 Advanced Receiver Transcoder provides the ability to deliver MPEG-4
high definition (HD) services to MPEG-2 cable television (CATV) head-ends. The
D9858 transcoder extends the distribution options for MPEG-4 Advanced Video
Coding (AVC) HD from solely MPEG-4 environments to existing MPEG-2 networks.
Support for simultaneous dual-channel transcoding provides density for locations
requiring more than just a single channel. The D9858 can be used to provide a down-
converted standard definition (SD) MPEG-2 program instead of one or both of the
available HD transcoded programs. A video and two audio monitoring outputs are
available for analog down-conversion for one of the decrypted incoming MPEG-4
HD programs.

Digital Cable/Telco Program Distribution

The Asynchronous Serial Interface (ASI) and MPEGoIP transport outputs are
individually configurable and can carry up to two decrypted transcoded programs
for digital tier distribution. This helps distribute the compressed video programs
efficiently to subscribers equipped with digital set -top boxes. Digital Program
Insertion (DPI) information is also be available along with the video and audio PIDs
(Packet Identifiers) for external ad insertion in compressed digital format. Digital
audio passthrough is synchronized to the transcoded program output. Compliant
Program Specific Information (PSI) and Service Information (SI) regeneration
provide integration into a digital tier distribution network for two transcoded
programs.
