The final part of the case for H.264 by Mark Harraway, UK Country Manager
Q. H.264 may prove unsatisfactory in situations where low latency is important. Is there any truth in this?
Again, I would have to say it depends on which manufacturer you are using. Latency is a function of the network – available bandwidth vs amount of traffic generated. As we have already said, using H.264 should improve network latency as you are reducing the bandwidth on the network by pushing the work to the edge device. If the concern is image delay (perhaps moving one’s hand in front of a camera and then seeing this on the screen), the issue comes down again to the truism that you get what you pay for. Higher build standard encoders or cameras will give quicker response times as they have faster processors and the manufacturers are likely to have implemented the profile better. Again this can all be adjusted in the individual codec settings.
