## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application is a continuation of International Application No. PCT/CN2013/086394, filed on Nov. 1, 2013, which claims priority to Chinese Patent Application No. 201210444015.8, filed on Nov. 8, 2012, both of which are hereby incorporated by reference in their entireties.


TECHNICAL FIELD
The present invention relates to the field of communications, and in particular, to a method for processing media content, a control point, a media server, and a media renderer in the field of communications.
BACKGROUND
With development of digital homes and digitization of consumer electronics (CE) products themselves, increasing digital entertainment devices and home electronic appliances are emerging in homes. Connecting these home area network devices in a wired or wireless mode to form a home area network to implement functions such as content sharing and mutual control, is a digital home area network concept that the industry is conceiving and striving to realize.
To implement interworking and control of various home devices, increasing home area network devices support Universal Plug and Play (UPnP), and therefore, the home area network devices may also be referred to as UPnP devices. In a UPnP system, a user controls a home device by using a control point (CP) in the home area network. The CP uses a UPnP protocol, and may read status information of a UPnP device in the home area network by invoking a related control command (Action) of the UPnP device, and control the UPnP device to execute a corresponding operation.
To implement media content sharing between various devices in the home, the UPnP Forum establishes an audio/video (AV) standard. The AV standard defines a media server used to provide AV media resources, and a media renderer used to perform decoding and play media from the media server. The Digital Living Network Alliance (DLNA) cites the UPnP AV standard, and defines device types such as a digital media server (DMS), a digital media renderer (DMR), and a digital media player (DMP).
The DLNA Authentication Task Force (Task Force) is studying a standard for client authentication with a server. The Task Force is studying how to solve an authentication requirement of a commercial video profile (CVP), so as to achieve an objective of allowing the CVP client to play paid content that is acquired from a CVP server (for example, a set top box) and provided by an operator.
Currently, a DLNA authentication technology provides only a 2-box scenario, that is, a scenario in which a CP and a media renderer are located in a same device. In this scenario, after performing authentication with an authentication server, the CP obtains a token, which indicates that the media renderer is authorized. For a 3-box scenario, that is, a CP and a media renderer are not located in a same device; after performing authentication with an authentication server, the CP obtains a token, which only indicates that the CP is authorized. However, other media renderers are not authenticated, and authorization thereof is unknown.
Therefore, if a user wants to push target media content to other media renderers for playing, on the one hand, when the user selects to push the target media content to the other media renderers, the user does not know which media renderers are authorized to play; and on the other hand, because the other media renderers are not authenticated, it is possible that the selected media renderer cannot play the target media content selected by the user.

DETAILED DESCRIPTION
The following clearly and completely describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. The described embodiments are a part rather than all of the embodiments of the present invention. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
FIG. 1 shows a schematic flowchart of a method 100 for processing media content according to an embodiment of the present invention. The method 100, for example, may be executed by a CP. As shown in FIG. 1, the method 100 includes the following steps.
S110. Send a control command to a media renderer in a home area network, where the control command is used to instruct the media renderer in the home area network to request authentication with an authentication server.
S120. Determine a first content list, where the first content list includes media content items that can be played by media renderers authenticated by the authentication server.
S130. Display the first content list to a user.
S140. Send, according to target media content that the user selects to play from the first content list and a target media renderer that the user selects for playing the target media content, a uniform resource identifier of the target media content to the target media renderer, so that the target media renderer acquires and plays the target media content.
A CP may send a control command to a media renderer in a home area network, to trigger the media renderer to perform authentication with an authentication server. The CP may thereby determine a first content list including media content items that can be played by authenticated media renderers, and thereby may display the first content list to a user; after the user selects target media content to be played from the first content list, and the user selects a target media renderer for playing the target media content, the CP may send a uniform resource identifier of the target media content to the target media renderer, so that the target media renderer may acquire and play the target media content.
Therefore, with the method for processing media content according to the embodiment of the present invention, a content list displayed to a user includes media content items that can be played by media renderers authenticated by an authentication server, so that media content selected by the user can be played by the authenticated media renderers. In this way, it can be avoided that a media renderer selected by the user is not authorized to play or not capable of playing the media content.
It should be understood that in the embodiment of the present invention, only an application scenario in the home area network is used as an example for description, and each device in the home area network performs communication based on a UPnP protocol; however, the present invention is not limited thereto. For example, each device in the home area network may perform communication based on communication methods of various communication systems.
It should also be understood that the communication systems, for example, include a global system for mobile communications (GSM) system, a code division multiple access (CDMA) system, a wideband code division multiple access (WCDMA) system, a general packet radio service (GPRS) system, a long term evolution (LTE) system, an LTE frequency division duplex (FDD) system, an LTE time division duplex (TDD) system, a universal mobile telecommunication system (UMTS), a worldwide interoperability for microwave access (WiMAX) communication system.
It should also be understood that in the embodiment of the present invention, the CP and the media renderer may belong to a same device, that is, the CP is the media renderer; certainly, the CP and the media renderer may also belong to different devices, but the present invention is not limited thereto. Similarly, in the embodiment of the present invention, the authentication server and a media server may be located in a same device, and may also belong to different devices; however, the present invention is not limited thereto.
In S110, the CP may send a control command to a media renderer in the home area network, where the control command is used to instruct the media renderer in the home area network to request authentication with the authentication server, so that the media renderer is triggered to perform authentication.
In the embodiment of the present invention, the CP may send the control command to all media renderers in the home area network, to trigger all the media renderers to perform authentication; the CP may also trigger only a part of the media renderers in the home area network to perform authentication. In another aspect, all the media renderers receiving the control command sent by the CP may perform authentication with the authentication server, or only a part of the media renderers perform authentication with the authentication server; however, the present invention is not limited thereto.
For example, the CP may send a Hypertext Transfer Protocol (HTTP) based UPnP control command to a media renderer. For example, the CP sends a StartAuthentiction( ) command to the media renderer, to trigger the media renderer to perform authentication with the authentication server; the media renderer may establish a transport layer security (TLS) connection to the authentication server, and use a certificate for mutual authentication. The authenticated media renderer receives a token sent by the authentication server, where the token may include authentication status information of the media renderer, for example, authentication or authorization information; in addition, the authentication server records information of the authenticated media renderer, for example, records identity and capability information of the authenticated media renderer.
In S120, the CP determines the first content list, where the first content list may include media content items that can be played by media renderers authenticated by the authentication server. That is, the media content items included in the first content list may be played by at least one authenticated media renderer.
In the embodiment of the present invention, optionally, the media content items included in the first content list indicate media content items that the authenticated media renderers are authorized to play, or indicate media content items that the authenticated media renderers are authorized to play and capable of playing.
In the embodiment of the present invention, optionally, the first content list further includes media content items that can be played by the CP. Similarly, the media content items that can be played by the CP may indicate media content items that the CP is authorized to play, or may indicate media content items that the CP is authorized to play and capable of playing. Processing procedures in different cases are hereinafter described with reference to specific examples. For brevity, no further description is provided herein.
In S130, the CP may display the first control list to the user.
For example, the CP may determine, in a user interface (UI) list, a proper electronic program guide (EPG) UI, and display it to the user. The EPG UI includes the first content list. The content items in the first content list may include resolution and format information of the media content, for example, high definition (HD)/H.264 and standard definition (SD)/H.264.
It should be understood that in the embodiment of the present invention, the CP may use a method of a remote user interface (RUI) to display the determined EPG UI to the user; the CP may also use a method of a content directory service (CDS) to display the EPG UI; certainly, the CP may also use other methods to display the first content list to the user, but the embodiment of the present invention is not limited thereto.
In S140, the CP may send, according to the target media content that the user selects to play from the first content list and the target media renderer that the user selects for playing the target media content, the uniform resource identifier (URI) of the target media content to the target media renderer, so that the target media renderer acquires and plays the target media content.
In the embodiment of the present invention, when the media content items included in the first content list indicate media content items that the authenticated media renderers are authorized to play and capable of playing, for example, after the user selects a “Play” or “Play to” button in a specific content item in the first content list, the CP may match the media renderers that are capable of playing target media content corresponding to the content item with media renderers that are in an online state, and display media renderers that are capable of playing the target media content and are still in the online state (that is, finally effective media renderers) to the user, so that the user can further select the target media renderer for playing the target media content.
It should be understood that in the embodiment of the present invention, when the media content items included in the first content list indicate media content items that the authenticated media renderers are authorized to play, the CP further needs to match capabilities of the media renderers, to determine media renderers that not only are authorized to play and capable of playing the target media content but also are in the online state, so that a media renderer finally selected by the user can play the target media content.
In the embodiment of the present invention, the user may select, from the finally effective media renderers displayed by the CP, a target media renderer for playing the target media content, and after the user determines the target media renderer, the CP sends the URI of the target media content to the target media renderer, for example, the CP may send setAVTransportURI( ) and Play( ) instructions to the target media renderer. Thereby, the target media renderer establishes a security connection to the media server, for example, a TLS connection, and the target media renderer requests the target media content from the media server according to the received URI of the target media content. The media server checks the token of the target media renderer, and after determining that the target media renderer is effective, may send the target media content to the target media renderer. In this way, the target media renderer may play the target media content selected by the user, and a case in which the media renderer is not authorized to play the target media content or the media renderer is not capable of playing the target media content and the like does not occur.
Therefore, with the method for processing media content according to the embodiment of the present invention, a content list displayed to a user includes media content items that can be played by media renderers authenticated by an authentication server, so that media content selected by the user can be played by the authenticated media renderers. In this way, it can be avoided that a media renderer selected by the user is not authorized to play or not capable of playing the media content, and therefore user experience can be improved.
A method for determining a first content list by the CP is hereinafter described in detail with reference to FIG. 2 to FIG. 6.
As shown in FIG. 2, the determining a first content list in S120 in FIG. 1 includes the following steps.
S121. Acquire identity information of the media renderers authenticated by the authentication server and a second content list including all or a part of media content items on a media server.
S122. Acquire, according to the identity information, capability information of the media renderers authenticated by the authentication server.
S123. Determine the first content list according to the capability information and the second content list.
For example, the first content list may be determined according to the capability information and by matching the second content list.
In S121, the CP may acquire the identity information of the media renderers authenticated by the authentication server from the media server, or the CP may also acquire authentication status information of each media renderer from the media renderer, and thereby acquire the identity information of the media renderers authenticated by the authentication server. Detailed descriptions are provided hereinafter with reference to FIG. 5 and FIG. 6 separately. It should be understood that the CP may also use other methods to acquire the identity information of the media renderers authenticated by the authentication server; however, the embodiment of the present invention is not limited thereto.
It should also be understood that the CP may acquire the identity information of all the media renderers authenticated by the authentication server, or may also acquire the identity information of only a part of the media renderers authenticated by the authentication server; however, the embodiment of the present invention is not limited thereto.
In S121, the CP may acquire the second content list from the media server, where the second content list may include all the media content items on the media server, or may include only a part of the media content items on the media server; however, the embodiment of the present invention is not limited thereto.
For example, the CP may send a getUI https request to the media server; after the media server determines an identity of the CP, the media server may send a UI list to the CP, where the user interface list may include all or a part of UIs that the CP is compatible with, and the UI may include a list of all or a part of media content on the media server.
In S122, the CP may request, according to the identity information of the media renderers authenticated by the authentication server, the capability information thereof from the media renderers authenticated by the authentication server.
For example, after acquiring identity information of a media renderer authenticated by the authentication server, the CP may send a getProtocolInfo( )instruction to the media renderer authenticated by the authentication server, and the media renderer receiving the instruction (that is, the media renderer authenticated by the authentication server) may return its capability information to the CP, where the capability information of the media renderer, for example, may include a media format and a transmission protocol.
In S123, the CP may determine, according to the capability information of the media renderers authenticated by the authentication server and by matching the second content list, media content items that can be played by the media renderers authenticated by the authentication server, among the media content items included in the second content list, and thereby may determine the first content list.
For example, the CP may filter the second content list by matching media formats supported by the media renderers with format information included in the media content items, and thereby determine the first content list. It should be understood that the CP may also use other parameters to perform a matching operation; however, the embodiment of the present invention is not limited thereto.
It should be understood that in each embodiment of the present invention, when the first content list further includes media content items that can be played by the CP, the CP further needs to match the second content list with reference to capability information of the CP, to determine the first content list including the media content items that can be played by the CP and/or the media renderers authenticated by the authentication server.
Therefore, with the method for processing media content according to the embodiment of the present invention, a content list displayed to a user includes media content items that can be played by media renderers authenticated by an authentication server, so that media content selected by the user can be played by the authenticated media renderers. In this way, it can be avoided that a media renderer selected by the user is not authorized to play or not capable of playing the media content.
FIG. 3 shows another schematic flowchart of a method for determining a first content list according to an embodiment of the present invention. As shown in FIG. 3, the determining a first content list in S120 in FIG. 1 includes the following steps.
S124. Send a first list request to a media server.
S125. Receive the first content list that is sent by the media server according to the first list request, where the first content list includes media content items that can be played by at least one media renderer among all the media renderers authenticated by the authentication server.
For example, the CP may request the first content list from the media server; the media server may determine the first content list according to the request of the CP, and identity information and capability information, recorded or acquired by the media server, of the media renderers authenticated by the authentication server, and by matching media content items on the media server, where the first content list may include media content items that can be played by at least one media renderer among all the media renderers authenticated by the authentication server.
It should be understood that in the embodiment of the present invention, if the media server does not record the identity information and/or capability information of the media renderers authenticated by the authentication server, or the media server cannot acquire the identity information and/or capability information of the media renderers authenticated by the authentication server, when the CP requests the first content list from the media server, the request may carry the identity information and/or capability information of all or part of the media renderers authenticated by the authentication server.
FIG. 4 shows still another schematic flowchart of a method for determining a first content list according to an embodiment of the present invention. As shown in FIG. 4, the determining a first content list in S120 in FIG. 1 includes the following steps.
S126. Acquire identity information of the media renderers authenticated by the authentication server.
S127. Send a second list request to a media server according to the identity information, where the second list request includes identity information of specified media renderers authenticated by the authentication server.
S128. Receive the first content list that is sent by the media server according to the second list request, where the first content list includes media content items that can be played by at least one media renderer among the specified media renderers authenticated by the authentication server.
The CP may acquire the identity information of the media renderers authenticated by the authentication server from the media server, or the CP may also acquire authentication status information of each media renderer from the media renderer, and thereby acquire the identity information of the media renderers authenticated by the authentication server. Detailed descriptions are provided hereinafter with reference to FIG. 5 and FIG. 6 separately. The second list request sent by the CP to the media server may include the identity information of the specified media renderers authenticated by the authentication server, and may further include other information, such as capability information, of the specified media renderers authenticated by the authentication server, so that the media server may determine the first content list including media content items that can be played by at least one media renderer among the specified media renderers authenticated by the authentication server.
Similarly, it should be understood that in the embodiment of the present invention, when the first content list further includes media content items that can be played by the CP, the media server further needs to determine, with reference to capability information of the CP, the first content list including the media content items that can be played by the CP and/or the media renderers authenticated by the authentication server. It should also be understood that if the media server does not record the capability information of the CP, the second list request sent by the CP to the media server may carry the capability information of the CP, or the media server may acquire the capability information of the CP by using other methods; however, the embodiment of the present invention is not limited thereto.
In the embodiment of the present invention, when the media server determines the first content list and sends it to the CP, if a method of an RUI is used to display the first content list to the user, the media server may directly annotate, in the first content list, identity (ID) information of corresponding media renderers capable of playing the media content, so that when the user selects the target media content to be played, the CP may display names and identities of these media renderers to the user directly according to the information of the corresponding media renderers capable of playing in the first content list. That is, in the embodiment of the present invention, optionally, the first content list includes the identity information of the media renderers that are capable of playing the media content items and are authenticated by the authentication server.
In the embodiment of the present invention, optionally, content descriptions of the media content items in the first content list include the identity information of the media renderers that are capable of playing the media content items and are authenticated by the authentication server. For example, when a method of a CDS is used to display the first content list to the user, the media server may match the information of the media renderers authenticated by the authentication server with content information in the CDS, to match the content items that can be played by the media renderers authenticated by the authentication server. For each content item, if a media renderer capable of playing the content item, namely, an effective media renderer (each content item may be corresponding to one or more effective media renderers) exists, the media server may add these effective media renderers as a new attribute element of the content item to a content description of the content item, that is, the media server may directly annotate, in the content description of the media content item in the first content list, the identity information of the media renderers that are capable of playing the media content item and are authenticated by the authentication server.
For example, the CDS may be extended, and an attribute element named possibleMediaRenderer is added to a content description in the CDS, where possibleMediaRenderer indicates a media renderer that is capable of playing the content and is authenticated by the authentication server. An example thereof is as follows.

S1211. Send an identification request to the media server.
S1212. Receive an identification reply that is sent by the media server according to the identification request, where the identification reply includes the identity information of the media renderers authenticated by the authentication server.
For example, the CP may send a request named getAutenticatedMR( ) to the media server, to request the identity information of the media renderers authenticated by the authentication server and recorded by the media server; after receiving the identification request, the media server may send the identity information of the recorded media renderers authenticated by the authentication server to the CP, and therefore the CP may acquire the identity information of these media renderers.
It should be understood that in each embodiment of the present invention, terms “request”, “reply”, “response”, and the like only represent a carrier that carries information or content, for example, a message, and are not limited to specific names. In addition, the term “reply” or “response” is not limited to a response or a reply to a “request”, and may represent only some information or content, or represent a carrier of some information or content, for example, a message; however, the embodiment of the present information is not limited thereto.
