# streaming/stream-hdmi-in/stream-hdmi-in-then-decode-and-display-on-hdmi-out/brightscript-and-html
2+
This script creates a multicast stream from the HDMI input on a BrightSign player.
3+
Any device or PC on the local network that can accept a UDP stream can receive and play this stream.
4+
In addition, the script decodes the stream and plays it back on the local HDMI output.
5+
The encoding is done in BrightScript, and the decoding is done in HTML.
6+
This sample illustrates how to tune to a multicast stream in HTML.
7+
To run this sample, put all files in this folder on an SD card, insert it in a BrightSign player, and reboot.
8+
9+
Notes:
10+
- This requires a BrightSign model that has an HDMI input
11+
- You can only stream non-encrypted content. If you attempt to stream, for example, the output of a DVD player, it will be disallowed
