Multi Video Index



The first video module within an encoder card should use the multi_video_idx of 1



Subsequent video modules should increment in value from 1 (i.e. 2, 3, etc.)



This range should be the same for all encoder module types, regardless of video encoder type (e.g. MPEG2, H264).



Legacy encoder configuration should not change

TS Bit rate overheads for the Video Processor in nCC



When the TS rate is changed on the output of the Video Processor, there is a small period of disruption. As the nCC

dynamically allocated this rate depending on component rates, a compromise solution is that the nCC configures each

multicast by default from a Video Processor at 20 MBit/s TS rate. This has a safety feature in case the TS rate required is

greater than this value then the dynamic update takes precedence.

NOTE : In large systems it may be necessary to reduce the TS rate due to input TS rate limits in the Multiplexers.

Multi-VCM Operation & Redundancy



The Video Processor spare must have sufficient duplicate VCMs to switch the entire chassis



The Video Processor in R2AFD1 supports inter-chassis redundancy only

– Redundant VCM must be in spare chassis, not same chassis

Redundancy Steps:

Chassis Failure



Entire Chassis switches all VCMs simultaneously

Single VCM failure (detected by loss of TS detected by MUX)



nCC begins switch



If second VCM failure detected then entire chassis switches

Transport Stream Output
