The RVU protocol (RVU) is a communications protocol, built substantially upon the pre-existing Digital Living Network Alliance (DLNA) standards. The RVU protocol is intended to solve the problems inherent in viewing live or recorded digital media remotely across a Home network. For example, a RVU compliant TV will be able to view music, photos & videos from an RVU compliant media server. The RVU protocol specifically can deal with the passing of 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. The RVU protocol also includes a RUI technology that allows an RVU compliant media server to fully control the user experience on an RVU compliant client device.

Overview

The RVU Protocol was defined to solve the problem of how to provide a consistent television user interface throughout the home, without requiring the use of a dedicated set-top box for each television. The RVU Protocol is a communications protocol which runs on a service provider supplied server device and multiple client devices. RVU uses open standards (including DLNA and UPnP) which are already in use in the consumer electronics field.

The clients can consist of various manufacturer-branded TVs, BluRay players or other client devices. The server generates the user guide and other data and sends this for the client to display. In this way the clients can be low complexity or "thin" client devices, while still providing a full user interface experience to the user. Once an RVU compliant device is connected to an RVU server, the TV viewer can watch the same or different content from any room of the home. Viewers can access the same prerecorded or live content from the server via the client device as if a set-top box were present, with the same user guide experience.

RVU supports networking on existing home infrastructure, but is agnostic to the transport mechanism and can work on wireless technologies such as 802.11 or wired technologies such as Ethernet or MoCA.

RVU supports a Remote User Interface (RUI) that allows user interactions such as trick play (e.g., pause and rewind) and the running of interactive applications.

History

The RVU Protocol specification V1.0 was released on 3rd December 2009.

Specification

The RVU Protocol specification V1.0 is currently ratified by the board and available to members for implementation.

The specification is in large part dependent on the DLNA specification.

The specification uses DTCP/IP as "link protection" for copyright-protected commercial content between one device to another.[1]

Certification

RVU certification Devices will be subject to certification by the [[[RVU Alliance]]]. Certification procedures are under development by the [[[RVU Alliance]]].
