Abstract:
A home networked controller device leverages discovery and control services to improve interoperability between devices that share multimedia content by re-serving the content wrapped in a remote user interface to enable client devices that have the capability to play the content but that require a remote user interface to be present.

Description:
I. FIELD OF THE INVENTION 
     The present application pertains generally to home network controllers with remote user interface wrapper of discovered multimedia content. 
     II. BACKGROUND OF THE INVENTION 
     Home network discovery and control is encapsulated in a variety of standards such as Zeroconf, universal plug-n-play (UPnP), and Airplay. UPnP is an example of a technology that offers a very flexible architecture for managing connectivity of devices that share remote user interfaces and multimedia in the home. Digital living network architecture (DLNA) standardizes this by adding media formats and specific transport protocols to the basic UPnP devices. As understood herein, however, complexity arises when trying to combine the following two opposing scenarios. One is when a content server expects content selection to be part of a remote user interface that is delivered along with the multimedia playback functionality to the client. In this case, the client need only discover and connect to the remote user interface service for the content to be made available. In contrast, the situation may arise in which an application with its own user interface resides on the client that discovers the selection of available content from available services on the home network and presents them to the user. Complexity arises when a content server delivers some of its content bundled together with a remote user interface and some of it is expected to be discovered independently by clients. As a consequence, the user of the client device is potentially faced with navigating through their devices menu system to switch applications to search and playback the different content sources in their home. In addition, each multimedia capable application may have diverse capabilities that lead to frustration when content that is played one way, e.g., through the remote user interface, doesn&#39;t work when played another way, e.g., through independent media player application. 
     SUMMARY OF THE INVENTION 
     Present principles recognize that ideally, the client user experience should be unified through one approach. 
     Accordingly, a controller has a processor and a computer readable storage medium accessible to the processor and bearing instructions executable by the processor to configure the processor to adapt different sources of content to a client device on a network through a single user interface (UI) provided by the controller to the client device to transparently enable the client device to also receive content for playback that was initially presented without a remote UI. 
     The controller may be embodied by the client device or may be physically separate from the client device. The controller processor may also transform multimedia content into content which is wrapped in the remote UI such that multimedia content is embedded in the remote UI. The controller combines discovery functionality for discovering multimedia content with remote UI serving device functionality so that playback of the multimedia content is achieved on client service applications that only handle multimedia content offered as part of a remote UI. In example implementations, the remote UI is a discoverable web browser with audio video (AV) playback. The server may provide the remote UI in one example, whereas in another example the server provides no remote UI and provides only AV content, and the controller stores the remote UI, discovers the AV content on the server, and wraps a content list representing the content in the remote UI prior to providing the remote UI to the client device. The content list may be derived by the controller from the content discovered on the server by the controller. 
     In another aspect, a controller includes a processor and a computer readable storage medium accessible to the processor to configure the processor to execute discovery of a server of audio video (AV) content and a client device configured to play the AV content. The server does not source a remote user interface (UI) to the client device. The controller processor discovers AV content on the server and then provides, in a remote UI at the controller, a list of AV content on the server. The controller delivers the remote UI with the content list wrapped therein to the client device. 
     The details of the present invention, both as to its structure and operation, can best be understood in reference to the accompanying drawings, in which like reference numerals refer to like parts, and in which:

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring initially to  FIG. 1 , a system is shown, generally designated  10 , which includes a controller  12  according to present principles communicating in a local network such as a home network using, e.g., DLNA, with one or more client devices  14  such as TVs and one or more multimedia servers  16 , which may be established by any appropriate serving device such as a disk player, personal video recorder, and the like. 
     The controller  12  includes one or more processors  18  accessing one or more computer readable storage media  20  such as disk-based or solid state storage to cause the processor  18  to execute logic described herein. The controller  12  also includes one or more network interfaces  22  such as wired or wireless modems, Ethernet ports, universal serial bus (USB) ports, Bluetooth transceivers, etc. to support communication in the network among the devices. 
     The server  16  includes one or more processors  24  accessing one or more computer readable storage media  26  such as disk-based or solid state storage to cause the processor  24  to execute logic described herein. The server  16  also includes one or more network interfaces  28  such as wired or wireless modems, Ethernet ports, universal serial bus (USB) ports, Bluetooth transceivers, etc. to support communication in the network among the devices. 
     The client device  14  includes one or more processors  30  accessing one or more computer readable storage media  32  such as disk-based or solid state storage to cause the processor  30  to execute logic described herein. The client  14  also includes one or more network interfaces  34  such as wired or wireless modems, Ethernet ports, universal serial bus (USB) ports, Bluetooth transceivers, etc. to support communication in the network among the devices. Typically, the client device  14  outputs video on a display  36  and outputs audio on speakers  38 . The client device may be a TV, a game console, a laptop or slate computer, a home theater system, or other client device that typically establishes a “sink” for playing high definition multimedia interface (HDMI) content received from a HDMI source such as the server  16 . Note that while the figures herein show separate client devices  14 , controller  12 , and server  16 , the controller  12  in some embodiments may be embodied in the client device  14  or the server  16 . 
     According to present principles, the controller  12  adapts different sources of content to the devices  14  and services on the network and manages these through a single user interface provided by the controller with the specific aim of transparently enabling clients with remote user interface capability to also receive content for playback that was initially presented without a remote user interface. The controller may be embodied in a remote device such as a tablet computer or smartphone, or as mentioned above it could be part of the client device  14 . 
     According to present principles, multimedia such as audio-video content is transformed by the controller  12  into content which is wrapped in a remote user interface (UI). In other words, multimedia content is embedded in a remote UI. In so doing, the functionality provided by a control point, such as an UPnP control point, for discovering multimedia content is uniquely combined with the functionality offered by a remote UI serving device so that playback can be achieved on client service applications that only handle multimedia content offered as part of a remote UI. 
     An example is a discoverable web browser with audio video (AV) playback. In this case, the AV is enabled in the browser through elements of a remote UI service (e.g., the browser application) that is served to it. 
       FIG. 2  illustrates the case where device discovery is executed using, e.g., UPnP, in which the server  16  has only discoverable AV, which is discovered by the controller  12  in step (1), not a remote UI. Accordingly, the controller  12  acts as the source of the remote UI in which is wrapped the content list, which is then delivered to the client (step 2). The content list is presented in the remote UI at the client device at step (3). The AV is pulled by the client  14  from the server  16  in step (4). The controller application can optionally also act as the device remote control for user input where the control is either through the network (using UPnP processInput actions for instance) or through infrared, Bluetooth and other wireless technologies. 
     In some examples embodiments of this is the home network connected TV use case. This includes but is not limited to interoperability in the DLNA ecosystem of devices and services, recognizing that the trend for future TV content and services to be delivered through home networks is to leverage the ubiquity and preference of supporting HTML5 user agents (e.g., browsers) on clients. HTML5 user agents offer video playback though a HTMLVideo element that is enabled by an application that runs on it. 
     The controller  12  described above solves the complexity issue by leveraging the fact that if the HTML5 user agent on the client  14  can be standardized to include playback of DLNA content, and if all content can be presented through a remote user interface, then the client need support one application and thus provide a single seamless user experience to access all the content in the home. In addition, when the remote user interface that wraps the content is based in HTML5 many different skins and presentation techniques are possible to allow user experiences to evolve and improve quickly, since HTML, CSS and JavaScript are the familiar tools of the manifold web development communities. 
     While the particular HOME NETWORK CONTROLLER WITH REMOTE USER INTERFACE WRAPPER OF DISCOVERED MULTIMEDIA CONTENT is herein shown and described in detail, it is to be understood that the subject matter which is encompassed by the present invention is limited only by the claims.
