Cisco D9858-1 Advanced Receiver Transcoder

Product Overview

The Cisco® D9858-1 Advanced Receiver Transcoder (Figure 1) can deliver MPEG-4 high definition (HD) services
to MPEG-2 cable television (CATV) headends. The D9858-1 extends the distribution options for MPEG-4
Advanced Video Coding (AVC) HD from solely MPEG-4 environments to existing MPEG-2 networks. Like the
award-winning Cisco D9858 Advanced Receiver Transcoder, the D9858-1can be used as a single-channel
receiver for applications that require less density. It can also be used to provide a down-converted standard
definition (SD) MPEG-2 program instead of the HD transcoded program, using either manual or Active Format
Descriptor (AFD) control of the aspect ratio conversion. Video and two audio outputs are available for analog
down-conversion of the decrypted incoming MPEG-4 HD program.

Digital Program Distribution

The Asynchronous Serial Interface (ASI) and MPEGoIP transport outputs are individually configurable and can
carry a decrypted transcoded program for digital tier distribution. This helps distribute the compressed video
programs efficiently to subscribers equipped with digital set-top boxes. Digital audio pass-through 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 a transcoded program.

Digital Program Mapping

Digital Program Mapping allows programmers to substitute programs at the uplink. It maintains predictable and
compliant transport output during service replacement, network information table (NIT) retuning, channel changes,
including forced tunings. This feature remaps the packet identifier (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 alternative programming in the digital tier.

Digital Advertisement Insertion

Digital program insertion (DPI) information is available along with the video and audio PIDs for external
advertisement insertion in compressed digital format on the transcoded program.
