I've been reading thru the External Control Guide (http://sdkdocs.roku.com/display/sdkdoc/ ... trol+Guide). I'm looking for ways to control a Roku thru the network to always make sure it's launched into a specific app playing a live video stream. It will be attached to a public TV and act as a digital signage system.
One concern would be how to monitor the system remotely, to make sure the video is being played out. The complicated solution is to have the app ping some web service periodically, and when it stops pinging, that means the video stopped play out and to re-launch the channel remotely.
I'm looking to see if I could ping the Roku instead, by sending it an input query and getting some response back. However, the external control guide doesn't make any mention of getting a response from input commands sent to the app.
Does anyone know if that's possible, or have some suggestions for what I'm trying to accomplish?
