4. MY TRANSMISSION IS ROBUST OVER DISTANCE, BUT VIDEO QUALITY IS NOT AS GOOD
AS I'D LIKE.
Assuming the RF transmission is good, and can support high video bit rates, another factor
affecting perceived video quality is the delay (latency) setting.
Low delay modes present the images in the fastest possible time to the receiver, but quality
will be lower than in a higher delay setting where the picture can be processed more accurately.
If there are no other fixed wired cameras on the shot showing the same action, higher delay
settings should be used for best quality.
5. I DON'T SEEM TO BE ABLE TO COVER MUCH DISTANCE WITH MY HEROCAST.
Not only are the transmitter RF parameters discussed above influential on the distance your
transmitter will work, but equally important are the placement of the receive infrastructure
and the number of receive points. This subject is beyond the scope of this user manual and
should be discussed with your receiver installer.
6. IS THERE AN EASY WAY TO SUMMARISE THE WAY TO GET THE BEST OUT OF MY
SYSTEM?
Read all of the above discussion on the effects of RF and video parameters. A summary of
each parameter can be shown with this diagram, affecting the available bit rate vs. robustness,
and quality:
