Video data (ie mobile TV shows).

The above sharing can occur during a call in a circuit domain. That is, when in two terminals When either party needs to make a call in the circuit domain, it will not affect the sharing of mobile TV programs.

The implementation of the technical solution will be further described in detail below with reference to the accompanying drawings:

FIG. 1 is a schematic diagram of a system corresponding to a usage scenario of the present invention, including a TV program center, an IP network service server, a mobile TV base station, a mobile network base station supporting packet services, and a terminal. The TV program center is connected to the mobile TV base station through the mobile TV network, and the mobile TV base station delivers the mobile TV program to the terminal A having the mobile TV function. The IP network service server is connected to the mobile network base station supporting the packet service through the mobile communication network, and the mobile network base station serves the terminal B under it, and the terminal can be a terminal without a mobile TV function. In other embodiments, it is of course also possible to share on both terminals having mobile TV functions.

Mobile TV sharing in this article includes video sharing and audio sharing.

Figure 2 is a schematic diagram of the structure of the terminal module. There is a terminal A with mobile TV function and a terminal B without mobile TV function, but both terminals support video and audio sharing functions.

The terminal with mobile TV function includes a mobile TV processing module and an audio and video sharing function module, wherein:

The mobile phone television processing module comprises an audio and video data processing module and a mobile phone television signal receiving and decoding module, which are mainly used for normally receiving and playing mobile TV programs; the mobile phone television processing module can also send the decoded mobile TV program data to the mobile phone television program. Audio and video sharing function module (can be completed by mobile TV signal receiving and decoding module);

The audio and video sharing function module is configured to establish a voice and video sharing session with another terminal, and send the collected mobile TV program data to the peer mobile phone, including: a media collection module and a control processing module, and the media collection The module is mainly used for collecting decoded mobile TV program data (including audio and/or video); the control processing module is mainly used for signaling interaction with the opposite mobile phone, and for transmitting the collected mobile TV program data to Another terminal.

The set may be actively sent by the mobile phone television signal receiving and decoding module to the media collection module, or may be actively acquired by the media collection module from the mobile phone television signal receiving and decoding module, or driven from the audio and video device of the terminal. Obtained in the module. The terminal without mobile TV function, in order to realize the sharing of mobile TV, includes at least an audio and video sharing function module, which is used for establishing a voice and video sharing session, and receiving and playing a mobile TV program, wherein: a media playing module and a control processing module are included. The media playing module is mainly used for playing the received mobile TV program data; the control processing module is mainly used for signaling interaction with the opposite mobile phone, and is responsible for receiving the mobile TV program data sent by the opposite end.

The division of the above modules is merely an illustration of a method for providing mobile phone program sharing, and is not a limitation on the apparatus for implementing the method. Modules can be combined or re-partitioned as needed.

As shown in FIG. 2, in order to achieve the effect of the present invention, on the mobile phone supporting the mobile TV function, an interface exists between the audio video data processing module and the media collection module, and when the sharing is started, the former sends the audio and/or video data. Give the latter.

The control processing modules of the two mobile phones communicate through IP/SIP (Session Initiation Protocol), including establishing a shared audio and video session and transmitting media data under the control of the network service server.

Sharing of TV shows can also occur during a call.

The mobile TV program sharing signaling process is shown in Figure 3, including:

Step 301: The user selects a television program, and the UE1 receives and plays the mobile TV program according to a normal process;

Further, the receiving and playing of the mobile TV program is completed by the mobile TV module in the UE1. Specifically, the UE 1 receives a television program (audio and video) data stream and plays a television program using an external device such as a speaker/headphone or a display screen.

Step 302: The user of the UE1 wants to share the mobile TV program with the user of the UE2, that is, the UE2 user shares the same TV program through the mobile phone, and then sends a sharing command to the UE1 through the menu or the function button, and the UE1 sends the message to the UE2. INVITE (invitation) message, initiate a session establishment request (ie, audio and video sharing request), the INVITE message passes through the IP/SIP core network (or may also pass through the network service server), and arrives at another mobile phone UE2 supporting mobile TV sharing;

During the session establishment process of audio and video sharing, SIP signaling messages are all via the IP/SIP core network. (Or can also pass through the network business server), passed between the two phones.

Step 303: The UE2 responds to the 183 SESSION PROGRESS message to the UE1. In other embodiments, the step 303 may not be performed.

Step 304, UE2 responds to the 180 RING (ringing) message to UE1;

Step 305: After the UE2 user agrees to start video sharing, the UE2 responds to the 200 OK to the UE1. In step 306, the UE1 responds to the ACK message.

In the above process, the television program (audio video) data stream is still received by UE1.

After the completion of the step 306, the session is successfully established. In the session establishment process, the media packet (media packet) format and the media report are completed between the UE1 and the UE2 according to the SIP protocol and the Session Description Protocol (SDP) protocol. The address transmitted by the text is negotiated with the port, etc. After the negotiation is completed, a media message transmission connection such as a UDP (User Datagram Protocol) connection can be established. The above SDP protocol is a protocol used by the message body of the SIP message, that is, the protocol negotiated by the UE1 and the UE2 media, and the message body can use other protocols within the scope permitted by the protocol.

Step 307: The UE1 sends the received television program (audio and video media data message) to the UE2 through the media message transmission connection, and after receiving the television program, the UE2 plays the television program, so that two mobile phones simultaneously watch the same television program. .

When the UE2 user intends to end watching the mobile TV through mobile TV program sharing, the following process can be performed:

Step 310, UE2 sends a BYE message to UE1;

Step 311: The UE1 ends the mobile TV program sharing in response to the 200 OK message.

After the mobile TV program sharing is over, UE1 stops sending mobile TV programs (audio and video data streams) to UE2, but UE1 can continue to receive and play mobile TV programs.

In the above process, sharing can occur during a call in a circuit domain.

In the above embodiment, the core network is applicable to the 3GPP IMS domain, the 3GPP2 MMD domain, and other branches. The SIP/IP core network is suitable for GPRS/EDGE, CDMA, WCDMA, LTE, WiFi, WiMAX, etc. The terminal can be a combination of one or more of the above wireless systems, and the mobile TV supported by the terminal can be CMMB. , MBMS, DVB-H and other methods.
