What is the latency? Are there differences between different 2.4 gigahertz systems? Or is this kind of like across the bank, kind of the same delay?

No, I think it's different because the codecs in use are different.

So what is the processing power in your device, which means what is the energy consumption, what is the running time, so everything based here on energy.

But it's mostly 40 milliseconds.

So that's two frames, let's say, which is...

Not always audible because the cameras also have a latency between getting light on the sensor and writing a file onto the SD card, S by S card.

And of course, if you have a camera who knows the system, because the camera and the manufacturer of the radio mic are the same, so the receiver can tell the camera over metadata, I have 43 milliseconds delay, then the camera can... write the files or can write in the files at a delay of 42 milliseconds and then still in sync, which is not working if you have a camera which gives you a digital output for a monitor or if you are on set because the camera writing this on file in time and that is lip sync.

So why should a camera operator care about a meeting of regulators?
