I've been contacted about doing a live show. It will be my first. They are asking about the wireless video solutions I own. The video needs to be broadcast quality, and I'm certain my Modulus/Hermes cannot provide that. I'm pretty sure even the best Modulus, or even Canatrans with a diversity tuner wouldn't provide that with complete reliability. Is microwave the only real wireless solution to get broadcast quality? What is involved in setting up the equipment? Does it require an entire van to receive the signal, or are there more portable solutions?

As always, thanks very much for the help,

I recently worked at the Melbourne Cup horse racing and for the Steadicam the production provided us
D-Link Cameras. Not too sure how they work except to say they transmit a fairly decent picture which the TD can handle the same way as if you had a triax cable back to the OB truck. We were outside and the system was pretty much line of sight from the recievers antenna and covered the area we were in pretty well. However it radomly did still drop out or the colours would change. Luckily it never did at the wrong time. Either a minute before we were going on or a second or three after they cut out of us.

The only problem with this system was that there is a delay in the link. So if what you are shooting has alot of dialogue that requires lip syncing this system may not be good for you.

We were mainly shooting horses and their riders walking around the mounting yard so there was no need for syncing. When we needed to shoot presentations or the national anthem we had to swap to a different camera with a cable, so there was no sync loss.

Hope this helps a bit at least.

Yup, D-cam is very popular. http://www.gigawave.com and http://www.dcam.tv - rental is a few hundred a day, so not too pricy either.

if they are going to take your wireless signal to air, your best bet is a 2.4GHZ system or microwave. these are costly options for the operator. why cant the production rent this beast?

wireless links are unstable, line of sight or not. dependig on the envorinment, you could disrupt or interfere with other wireless equipment. a site survey is your best bet to see whats going on before you break down and look for solutions...

I advice to make sure that PRODUCTION takes care of any broadcast quality transmission equipment.
This is something they must garantee in its' performance, not the operator. Also, there are many systems out their, each with their own problems and handling issues. Why would you want to take that on your responsibility?
Of course, you and them have to make sure it works with your rig, so you might have to supply some simple stuff like attachments, but not more.

And if you would do this on a regular/daily/weekly basis you might discuss further with the production, but not for incidental occasions.
