A couple of weeks ago, I was contacted through the blog by Tony Perez, longtime staff member at Calvary Chapel in Las Vegas. He asked if I could help their team to control their Roland V-60HD switcher through a stream deck using Companion.
God has given me a heart and passion to be a resource for other churches, so I jumped right in and started reading the TCP protocol specification for their video switcher. The protocol was simple enough, basically just a telnet protocol to send parameters with a terminating character to designate the end of the command.
I had to take a sick day recently to take care of one of my kids who had an ear infection, so while he was resting, I sat down and prototyped a module for Companion to control their video switcher.
Tony and I then set a time to talk on the phone and do a TeamViewer session, and after doing some slight debugging, we had it working!
The protocol is pretty straightforward. For example, with this command:
The switcher will perform a cut between the current on-air source and the preview source. “\u0002” is the ASCII control code “02H” which tells the switcher that a command code is coming. “CUT” is the command , and the semicolon terminates the command.
We were able to implement every video-related operation and some of the system operations that seemed necessary to control remotely from a Stream Deck.
So, with just a few short hours of work, now his team can control their Roland V-60HD video switcher from anywhere on their network! This will be a great help and add to their flexibility.
This was a fun project to get to help with, especially since I had not ever seen or used this particular video switcher before, and I was able to help a ministry on the other side of the country.
