D9824 Advanced Multi Decryption Receiver
The D9824 Multi Decryption Receiver is designed for satellite content distribution
applications requiring Digital Video Broadcasting - Satellite (DVB-S) and Digital
Video Broadcasting - Satellite - Second Generation (DVB-S2) reception capabilities
with advanced digital outputs for digital tier program distribution. A built-in
decoder can decode an MPEG-2 or MPEG-4 Advanced Video Coding (AVC) high
definition (HD) program is also available for analog. By supporting decryption of up
to 32 Cisco PowerVu

Digital Program Distribution
The Asynchronous Serial Interface (ASI) transport output provides a number of
output modes and can carry decrypted programs for digital tier distribution. This
capability helps ensure that compressed video programs are efficiently distributed to
households equipped with digital set-top boxes.

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) retuning, and 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 with the video and audio
PIDs for external advertisement insertion in a compressed digital format.
