Not sure I agree, I think its worse than that:
1920pixels * 1080lines * 30 frames/sec * 20bits/sample in YUV
=> 1.244Gbps
Also, if you want to encode live material you have bigger problems. encoders have
pipeline delay but this must be limited, usually to a few hundred millisecods.
This means you can only decompose the stream into a few frames which you can
run on seperate cpus. Spatial decomposition of the frames helps too but this is
much more difficult to do well - i.e. to ensure you cannot see the joins.
