This page outlines how to decode four HD (1920x1080) videos simultaneously. This feature is currently only supported on XC4055, XTx45, XTx44, and XTx43 models and requires BOS 7.0.x or newer.
# Series 5 Players
While both Series 4 and 5 players use hardware to decode video, you don’t have to preallocate resources on Series 5 players. To play four videos, for example, just open four video players.
`GetDecoderMode()` will always return `1` on a Series 5 player, even though the player can play back multiple videos, so it’s not useful for Series 5 players. The player will decode slowly rather than failing if you request too many resources.
# Series 4 Players
## Decoder Setting
To achieve quad-HD decode, you will need to allocate video players to decoders manually using the `SetDecoderMode()` method, which is available on the [roVideoMode](docId\:QQ734nQz0hCwNI0uNSdMP) BrightScript object or [BSVideoMode](docId\:chWN7k3a18M3yEUkIs7qN) JavaScript object. If all the decoders are set to decode HD, there will be enough HD-capable video players available for quad-HD.
## Video Requirements
The video-encoding requirements for video files on all decoders are H.265 or H.264 at 1920x1080 resolution and any frame rate up to 60p.
## XT3/4 Decoder Example (JavaScript)
The following JavaScript example uses the *BSVideoMode.SetDecoderMode()* method to allocate resources for quad-HD decode. This method allows the video decoders to decode multiple HD files, and when the HTML plays, it will use whichever decoder is free.
```javascript
function setDecoders()
{
var videomode = new BSVideoMode();
videomode.SetDecoderMode(videomode.decoderModeList[0].decoderName, "HD", 1, "Decoder1", false);
videomode.SetDecoderMode(videomode.decoderModeList[1].decoderName, "HD", 1, "Decoder2", false);
}
```
The decoder name is allocated automatically and does not need to be specified, so the HTML is simple:
