RTSP
Android (and Xibo) support RTSP streams in a Region using the Local Video module.
Unless the site already has a streaming server, most customers that want a solution using TV invest in a PC with a TV card which runs VLC to publish a RTSP stream in the correct codec/container for Android. In some cases RTSP streams are available from TV providers that can be played on Android.
Local Video can be the path to a video stored on the device or the path to a on-line stream.
It is important to note that when using Local Video to play an on-line stream, should that stream become unavailable then the Layout will be prematurely ended and marked as invalid until it next plays.
