# AWS::MediaPackageV2::Channel MultiviewConfiguration
<a name="aws-properties-mediapackagev2-channel-multiviewconfiguration"></a>

The multiview configuration for a channel. A multiview channel composites video from several source channels into a single tiled output stream. Players receive one standard HLS or DASH stream instead of several separate streams. This setting is required when `InputType` is `MULTIVIEW`, and can't be set for any other input type.
