Note: Bandwidth requirements for J2K-encoded video depends on the actual picture; the upper limit can be defined in the V__line settings (Settings –> TX Stream –> J2K):

 

Please note that the bitrate is the total bitrate including audio and VANC data. If you add more audio channels, but do not increase the overall bitrate, the bitrate capacity for video decreases.
