This is a project to bring evangelistic videos to mission hospitals. This project, which is called TVs4Jesus, shows any mp4 video to TVs placed around a mission hospital, in waiting rooms and
wards. The system also makes the video/audio available for viewing over Wi-Fi for the patients mobile devices. The hospitals have the opportunity to play whatever content they want.
Please visit this website for more information.
I realize that this idea could be used in other locations.
