DSP Submodules
Media Processor
(DSP 4PAC)
Submodule
The Media Processor, or DSP 4PAC submodule is a high performance, program-
mable platform for the video headend platform. Software is licensable from
TANDBERG Television to give the Media Processor a wide range of functionality,
including MPEG-2 to MPEG-4 AVC Transcoding. Because it is programmable,
the Media Processor’s functionality can be changed as your requirements change.
As multi-function devices, 4PACs or Media Processors can do transcoding or tran-
srating. When they do transcoding, the 4 DSPs work cooperatively, and provide
ONE channel of transcoding, or, one transcoder input and one transcoder output
ports. When configured to do transrating, they can provide multiple transrator
input and output ports. The number of ports they provide depends on the config-
uration of the Media (DSP 4PAC) Processor:
•
If configured for High, it is one service per DSP, and a 4PAC will provide 4 transrator input /
output ports.
•
If configured for Medium, it is two services per DSP, and a 4PAC will provide 8 transrator
input / output ports.
•
If configured for Low, it is three services per DSP, and a 4PAC will provide 12 transrator input
/ output ports.
