Hi Ian,
Thank you very much for your valuable insights!
I have been using Cypress Technology's CIR-03 and CIR-12 (
https://www.cypress.com.tw/en/Product/Video/Extenders/CIR-03,
https://www.cypress.com.tw/en/Product/Video/Extenders/CIR-12) to control the power on/off of TVs on stage, and they have worked well so far. However, since the remote control operation is manual, as the number of TVs and cues increases, it becomes very labor-intensive, and the operators were struggling. When I came across the IP2IR-P, I thought that if I could incorporate infrared control into QLab's cue list and trigger it with the Go button, it would greatly increase flexibility and make show control much smoother and more convenient.
For devices with RS-232C or LAN ports that can be controlled, I am already doing that myself. In particular, recent projectors from Epson and Panasonic often have Art-Net control implemented, which allows for more detailed control compared to RS-232C or PJLink, and this has been very helpful.
Most consumer TVs, like those typically found in households, do not have serial ports, but they do have LAN ports. So, perhaps it is not impossible to directly control them via QLab with Wake-on-LAN or input switching (though I doubt this would be covered in the manual, haha). I would also like to test this separately from the IP2IR-P. Thanks again!
Best,
Tommy
