I quote from the "Operating Guide for 50VS69A 55VS69A and 62VS69A", "Your Hitachi brand digital television (the 'DTV') uses certain open source operating system software (the 'OS Software') distributed pursuant to GNU GENERAL PUBLIC LICENSE Version 2 and GNU LESSER GENERAL PUBLIC LICENSE Version 2.1, each as defined and published by the Free Software Foundation, Inc."
Among the list of software used are: Linux Kernal, busybox, dhcpdcd, ifupdow, net-tool, iptables, libstdc++5, glibc, libposixtime. Following this list it goes on to mention that if you would like to request a copy of the Source Code Modifications from HITACHI, please send an email to the following address: firstname.lastname@example.org. Following that, there is, in full, a copy of the GPLv2 and the GLGPLv2.1. That almost brought a tear of joy to my eye.
This TV has a serial port though I've yet to attempt to see if there is a console on it yet.
Anyway, I am posting this because I was amazed that after doing some Google searches it seems there is no mention of this on the web, nor is there a mention of it on Hitachi's site. I figured
If I find anything exceptionally cool once I finally try the serial port I shall return to post my findings. If anyone else discovers or does something cool with this TV I would love to know about it."
