Go to video-storm.com and look at their IRUSB dongle. I use one to control an Amazon Fire TV Cube and one to control a nVidia Shield. It is not obvious from the name of the device, but it will accept TCP/IP commands sent to the device over the network. I control both of these devices in my home theater using only TCP/IP. I am not sure if it will work with the Android-based Sony TV but I am sure their tech staff will know
