Abstract

Embodiments of the present invention relate to a method for content sharing, where the method includes: receiving a content share request, establishing a share session with a receiving terminal, and sharing session content, which is played on a first initiating terminal, with the receiving terminal; and receiving a state notification about transferring the played session content from the first initiating terminal to a second initiating terminal, and according to the state notification, ending the share session or continuing to share the session content continuously played on the second initiating terminal. According to the embodiments of the present invention, CoD content watched on the initiating terminal can be shared, and when transfer occurs between display terminals of the content share initiator, a content share AS can perceive the transfer, and continuity of the share session can be ensured. The present invention further relates to a device for content sharing.

First claim

What is claimed is:

1. A method for content sharing, comprising:
receiving a content share request, establishing a share session with a receiving terminal to share session content played on a first initiating terminal with the receiving terminal;
receiving a state notification about transferring the played session content from the first initiating terminal to a second initiating terminal, the state notification indicating whether to end the share session or continue to share the session content which is played on the second initiating terminal and, according to the state notification, ending the share session or continuing to share the session content, which is played on the second initiating terminal, with the receiving terminal; and
transferring the played session content from the second initiating terminal to a third initiating terminal that previously shared the session content played by the first initiating terminal when the state notification indicates continuing to share the session content.

2. The method according to claim 1 , wherein the receiving a content share request, establishing a share session with a receiving terminal to share session content, which is played on a first initiating terminal, with the receiving terminal comprise:
receiving the content share request, and subscribing to, from an IPTV control device, information of the content played on the first initiating terminal;
forwarding the share request to the receiving terminal to request to establish the share session; and
accessing, according to the information of the content played on the first initiating terminal, which is sent by the IPTV control device, the session content played on the first initiating terminal, and forwarding, to the receiving terminal through the share session, the session content played on the first initiating terminal.

3. The method according to claim 1 , wherein the state notification indicates ending the share session; and
the according to the state notification, ending the share session or continuing to share the session content, which is played on the second initiating terminal, with the receiving terminal comprises:
ending the share session according to the indication ending the share session.

4. The method according to claim 1 , wherein the state notification indicates continuing to share the session content played on the second initiating terminal; and
the according to the state notification, ending the share session or continuing to share the session content played on the second initiating terminal comprises:
continuing to share, with the receiving terminal according to the indication continuing to share the session content played on the second initiating terminal, the session content played on the second initiating terminal.

5. The method according to claim 4 , wherein the continuing to share, with the receiving terminal according to the indication information for continuing to share the session content played on the second initiating terminal, the session content played on the second initiating terminal comprises:
subscribing to, from the IPTV control device, information of the content played on the second initiating terminal; and
accessing, according to the information of the content played on the second initiating terminal, which is sent by the IPTV control device, the session content played on the second initiating terminal, and forwarding, to the receiving terminal through the share session, the session content played on the second initiating terminal.

6. The method according to claim 1 , wherein the state notification is a SIP REFER message which is extended to indicate ending share or continuing to share the session content played on the second initiating terminal.

7. A system for content sharing, comprising:
a content share application server, configured to receive a content share request, establish a share session with a receiving terminal to share session content, which is played on a first initiating terminal, with the receiving terminal;
an Internet Protocol Television control device, configured to transfer the session content, which is played on the first initiating terminal, to a second initiating terminal for playing, and send a state notification about transferring the played session content from the first initiating terminal to the second initiating terminal, the state notification indicating whether to end the share session or continue to share the session content which is played on the second initiating terminal; wherein
the content share application server is further configured to receive the state notification about transferring the played session content from the first initiating terminal to the second initiating terminal, and according to the state notification, end the share session or continue to share the session content, which is continuously played on the second initiating terminal, with the receiving terminal; and
the Internet Protocol Television control device is further configured to transfer the played session content from the second initiating terminal to a third initiating terminal that previously shared the session content played by the first initiating terminal when the state notification indicates continuing to share the session content.

8. The system according to claim 7 , wherein the Internet Protocol Television control device comprises:
a receiver, configured to receive a request message for transferring the played session content from the first initiating terminal to the second initiating terminal;
a transferor, configured to receive the request message sent by the receiver, and transfer the session content, which is played on the first initiating terminal, to the second initiating terminal for playing; and
a sender, configured to send, to the content share application server, the state notification about transferring the played session content from the first initiating terminal to the second initiating terminal.

9. The system for content sharing according to claim 8 , wherein the receiver is specifically configured to receive the request message which comes from the first initiating terminal and is used for transferring the played session content from the first initiating terminal to the second initiating terminal.

10. The system for content sharing according to claim 8 , wherein the content share application server is further configured to send, to the Internet Protocol Television control device, a subscription request for subscribing to a state of the content played on the first initiating terminal; and
the sender is further configured to send, to the content share application server according to the subscription request of the content share application server, information of the content played on the first initiating terminal, so that the content share application server establishes the share session with the receiving terminal according to the information of the content played on the first initiating terminal and shares the session content, which is played on the first initiating terminal, with the receiving terminal.

11. The system for content sharing according to claim 8 , wherein the request message received by the receiver indicates ending the share session;
the sender is specifically configured to send, to the content share application server, the state notification indicating ending the share session; and
the content share application server is configured to end the share session with the receiving terminal according to the state notification indicating ending the share session.

12. The system for content sharing according to claim 8 , wherein the request message received by the receiver indicates
