Default [Q] Trying to control Sony Bravia SmartTV

Hi!
Trawling through Google led me to a thread on this forum: ( http://forum.xda-developers.com/show...2091564&page=2 ), which mentions that a json command sent to a certain address on the TV will return a list of possible commands. I hope to figure out how I can use those commands with an Android app that I bought for creating custom remotes.
First, I need to figure out a simple way of sending the JSON command to the TV over my LAN, though. Would someone kindly suggest an easy method that will allow me to do this using my Android phone or my windows laptop?
Any suggestions or advice would be helpful. Thanks in advance!
