The sink terminal is set to: present the received business content.

The terminal in the system may be a user device, for example, a mobile phone, a computer, a sound system, a TV, or the like. The terminal can be used only as a source terminal, or only as a sink terminal, or as both a source terminal and a sink terminal.

The content server in this system is usually a third-party server that provides business content. In the system, the service content management method in the multi-device environment includes: the source terminal sends a service request message carrying the service identification information; after the content server learns the service request message, provides the service content corresponding to the service identification information for the one or more sink terminals. ; and the sink terminal presents the received business content.

The service identification information refers to information that is unique and can identify a service content and a service content acquisition address.

The system implements a terminal to control the presentation of service content of other terminals, and is applicable to a multi-device system, improving the system's capabilities and improving the user experience.

The system will be described in detail below by way of examples.

Embodiment 1

As shown in Figure 2, the system also includes a control device. The control device is a management server or gateway (eg, set-top box, home gateway) or a user-controlled terminal (eg, computer, mobile phone, TV, etc.). The above system units are logical units, which can be located on the same physical entity during actual deployment. For example, one server acts as a management device and a content server. When the control device is a gateway or a user master device, the terminal can connect to the control device through Bluetooth, WIFI (Wireless Fidelity) or wired communication; when the control device is a server, the terminal can pass WIFI, wired broadband or Connect the control device by means of mobile communication.

The source terminal is configured to: send a service request message carrying the service identification information to the management device; the control device is configured to: receive the service request message from the source terminal and forward the message to the content server, receive the service content from the content server, and send the service to the preset target terminal. Content, wherein the preset target terminal includes one or more sink terminals;

The content server is configured to: obtain a service request message from the management device, and send the service content corresponding to the service identification information to the control device;

The sink terminal is set to: present the received business content.

In this embodiment, the service content management method in the multi-device environment includes: the source terminal sends a service request message to the control device, where the service request message carries the service identification information; the control device receives the service request message and forwards the message to the content server; After learning the business request message, The service content corresponding to the service identifier information is sent to the control device; and the control device sends the service content to the preset target terminal, where the preset target terminal includes one or more sink terminals.

The preset target terminal may be only a sink terminal, and may also include a sink terminal and a source terminal. When the target terminal is included in the source terminal, the source terminal and the sink terminal can synchronously present the received service content. The control device stores information of the preset target terminal. For example, the system includes N terminals, and the management device sends the service content to the fixed M terminals regardless of which service request message is sent, and M is less than or equal to N. For example, the system includes N terminals, and the control device receives the service request message of the first terminal, sends the service content to the set K terminals, and after receiving the service request message of the second terminal, the set J is received. The terminal sends the service content, K and J are both less than N, and so on, corresponding to each terminal has a set of target terminals. The user can modify the configuration information of the preset target terminal according to the requirements.

After the management device sends the service content to one or more of the sink terminals, the information of the service content may also be sent to the source terminal or other sink terminal in the form of a notification message.

The following is explained by several specific examples.

Example one

The system includes a first terminal, a second terminal, a management device, and a content server. The user discovers a certain video program (for example, a live TV program) through the first terminal (for example, a mobile phone), and needs to be presented on the second terminal (for example, a TV). The implementation method includes the following steps:

Step 1. After the video program is found by the mobile phone, the service request (presentation request) message carrying the service identifier of the video program is sent to the control device.

Step 2: The control device sends the service request message of the program to the content server, and obtains the service content (video service content) from the content server.

Step 3: The management device delivers the service content to the TV according to the terminal specified by the configuration information (here, the second terminal).

If the configuration information in the management device is not configured with the second terminal, the mobile phone may change the configuration information in the management device when the service request message is sent to the management device, and add the second terminal as the presentation device.

Step 4. The TV presents the received business content.

The mobile phone can also configure the rendering device as its own in the configuration information of the management device. Watch the same video program simultaneously on your phone and TV.

As shown in FIG. 3, the multi-terminal presentation of the service sub-content is also supported in this embodiment. When the business content contains multiple split sub-contents, it can also be configured to present different sub-contents on different terminals. The sub-content included in the business content includes one or more of the following contents: video content, audio content, image content, text content, and online interactive information content, etc.; the control device is further configured to: send different sub-contents in the business content To the default target terminal.

Example two

The system includes a first terminal, a second terminal, a first device, a second device, a management device, and a content server. The user discovers an online interactive video service through the first terminal (mobile phone), but sends the video signal to the second terminal (TV), and sends the audio signal to the first device (high-quality audio device). The online interaction information is presented on the second device (computer) to give the user a better experience. The implementation method includes the following steps:

Step 1: After the online interactive video program is found by the mobile phone, the service request message carrying the service identifier of the program is sent to the control device and the presentation device is configured.

The management device stores device information (TV) for presenting video and user-presented device information (high-quality audio device) and device information (computer) for presenting interactive information, for example, device name/ID and its address, user The configuration information can be modified at any time.

Step 2. The control device sends a service request message to the content server, and obtains the service content from the content server.

Step 3: The control device sends the program video signal to the TV according to the preset target terminal (TV, high-quality audio and computer) specified by the configuration information, sends the audio signal to the high-quality audio device, and sends the interaction information to computer.

Step 4. The TV presents a program video signal, the high quality audio device presents an audio signal, and the computer displays interactive information.

For the interactive information transmitted in both directions, the computer sends the uplink message to the control device, and the control device forwards it to the content server to complete the interaction. The compatibility of different terminal support formats is also supported in this embodiment. The control device is further configured to: obtain a service content in a different format from the content server, where the service content in different formats corresponds to a format supported by different preset target terminals; or the service content obtained from the content server is converted and generated to correspond to different presets. The business content of the format supported by the target terminal; the control device is also set to:

In this embodiment, different terminals are also supported to present service content starting from different service time points. The control device is further configured to: for each preset target terminal, respectively send the service content starting from the time point corresponding to the corresponding time shift information.

The time shift information of the preset target terminal may be preset information saved in the control device, and the information may be fixed or modified and reset by the user. The time shift information of the preset target terminal may also be information carried when the terminal sends a service request message to the control device, and indicates time shift information of each preset target terminal.

For example, in a system including a first terminal, a second terminal, and a third terminal, for a non-live broadcast video program, the saved information in the control device includes different time shift information of the second terminal and the third terminal (ie, When the first terminal sends a service request message to the management device, the time shift information of the second terminal and the third terminal is specified in the message. For example, when the second device continues to present the current program, the third device can present the section n before or after 10 minutes.

The embodiment also supports the function of synchronizing service content to other terminals in the process in which the service content has been presented on one or more terminals.

The source terminal or the sink terminal is further configured to: send a presentation device synchronization request message to the management device when the terminal that is presenting the service content presents the service content;

The control device is further configured to: after receiving the presentation device synchronization request message, send the service content to the synchronization target terminal.

When the management device sends the service content to the synchronization target terminal, the service content is sent to the synchronization target terminal by using the time point when the device synchronization request message is received. The synchronization target terminal is a source terminal or a sink terminal. In this solution, the synchronization target terminal can be determined in the following two ways. In the first manner, the control device stores the information of the preset synchronization target terminal, and the information may be fixed or modified and reset by the user. Manner 2: The presence device or the sink device sends the presence device synchronization request message carrying the information of the synchronization target terminal.

For example, the second terminal is presenting a service content, the first terminal sends a presentation device synchronization request message to the management device, and the preset synchronization target terminal saved in the control device is the third terminal, and the management device sends the service to the third device. The content, so as to realize the process of presenting the service content by the second terminal, the third device is synchronized with the presentation of the second device.

For example, the second terminal is presenting a service content, and the first terminal sends a presentation device synchronization request message to the management device, and in the message, the synchronization target terminal is the third terminal, and the management device sends the service content to the third device. Therefore, in the process of presenting the service content by the second terminal, the presentation of the third device and the second device is synchronized.

The control device is further configured to: after receiving the presentation device synchronization request message, obtain the service content that meets the support format of the synchronization target terminal from the content server, and then send the content to the synchronization target terminal, or

In this embodiment, the function of displaying the service content between different terminals in the process of the service content being presented on the terminal is also supported. Different from the above synchronization process, in the present presentation switching function, the terminal that performs service content presentation before the control device controls the handover stops the presentation of the service content in the handover process.

The source terminal or the sink terminal is further configured to: send a presentation device switching request message to the management device when the terminal that is presenting the service content presents the service content;

The control device is further configured to: after receiving the presentation device switching request message, stop sending the service content to the terminal that is presenting the service content, and send the service content to the handover target terminal.

The handover target terminal is a source terminal or a sink terminal. In this solution, the handover target terminal can be determined in the following two ways. In the first mode, the control device stores the information of the preset switching target terminal, and the information may be fixed or modified and reset by the user. Manner 2: The device switching request message sent by the source terminal or the sink terminal carries the information of the handover target terminal. When the management device sends the service content to the handover target terminal, the service content may be sent from the starting point of the service content, and the subsequent service content that starts with the corresponding service time shift point may be stopped, according to different services. .

The control device is further configured to: after receiving the presentation device switching request message, obtain the service content that meets the support format of the handover target terminal from the content server, and then send the service content to the handover target terminal, or convert the service content into the support format of the handover target terminal. Send to the handover target terminal. Example three

The system includes a first terminal, a second terminal, a third terminal, a management device, and a content server. The user is presenting a certain video program through the first terminal (for example, a mobile phone), and needs to switch to the second terminal (for example, a TV) and the third terminal (for example, an IPAD) for presentation. The implementation method includes the following steps: 1. The mobile phone stops presenting the video program, and sends a service request message carrying the service identifier of the program to the control device.

Step 2: The control device sends the service request message of the program to the content server, and obtains the service content from the content server.

If the mobile phone also obtains the service content through the management device before, and the user wants to switch to other terminals and continue to watch, step 2 can be skipped without re-applying to the content server. The management device stops sending service content to the mobile phone and directly delivers the service content to the new device.

Step 3: The control device sends the service content to the TV and the IPAD according to the terminal specified by the configuration information (here, the second terminal and the third terminal).

Step 4. The TV and the IPAD simultaneously present the received service content.

It is clear that TV and IPAD can simultaneously present the same business content.

When the rendering device performs switching (for example, switching from a large-screen TV to a small-screen mobile phone), the management device can re-apply the business content (for example, a business content suitable for the mobile phone display format) to the content server according to the information of the switching target terminal. Or, the format conversion of the service content (for example, converting the service content conforming to the TV format into the service content of the mobile phone format), and then transmitting the converted service content to the handover target terminal. The content adaptation according to the terminal can be implemented by using related technologies, and details are not described herein again. Embodiment 2
