JSTx is used for displaying overlay graphics and text on top of a Philips television, changing channels, receiving remote control keys and changing television display modes. It is a command line utility to execute jointSPACE commands on a device that supports the jointSPACE protocol for Philips televisions (see http://jointspace.sourceforge.net for details on jointSPACE, which is based on DirectFB).
It is used in various home automation/internet-of-things projects.
There are three versions: 0.23 for 2009/2010 Philips televisions (xxx5 en xxx4 series), 0.24 for 2011-2012 televisions (xxx6-xxx7) and 0.24_2013 for 2013-2014 televisions (xxx8-xxx9 (only non-Android)). New Android sets (2014+) do not come with Jointspace and are not supported. It works on Linux operating systems. A Raspberry-Pi version is also available.

Genious tool, I just spent the last three days modifying it for a 2010 TV model, which does *NOT* react to h**p://tv_ip:1925 and added code to be aware of the current channel. Channel switching is faster than before, as "Ok" button is sent after channel number. And - finally - I can again skip commercials (return to current channel in 2/4/6mins). JSTx is constantly running on Windows7x64 as a proxy with invisible OSD, works nicely! Thx a lot!
Cool tool - especially for making very easy interactions with PC scripts through your Philips TV&Remote control.
