Digital Program Distribution

The Cisco D9854-I Advanced Program Receiver offers Asynchronous Serial Interface (ASI) transport output and MPEGoIP output (a licensed option). They provide a number of output modes and can carry a decrypted program 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 tuning. 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 alternate 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.
