The RVU protocol is an Application Layer protocol, that combines the pre-existing Digital Living Network Alliance standards and a new Remote User Interface protocol, which works similar to Remote Desktop Protocol. The RVU RUI protocol is intended to allow an RVU-enabled client, such as a TV, to receive a pixel-accurate display of the user interface available on an RVU server.
RVU, combined with DLNA's ability to transmit media across a home network, allows for the entire user experience of a media server to be transmitted to an RVU client, makes the user interface available via the RUI protocol while all processing is being done by the server software and plug-ins happen at the host computer; only the user interface is streamed to the client devices. The protocol is primarily intended to operate over a home network. The RVU protocol has been developed with a focus on passing broadcast video coming from a multichannel video programming distributor through a residential gateway or dedicated media server to other consumer electronic devices in the home. However the protocol has much broader applications than just this.
