Abstract

The disclosure discloses a method for sharing audio and/or video. The method includes the steps that: a first terminal writes audio and/or video from an audio-video providing module into a cache space according to a play request of a second terminal, and transmits the audio and/or video stored in the cache space to the second terminal.

The disclosure further discloses a system for sharing the audio and/or video. With the disclosure, a video conference of a mobile terminal can be displayed at a digital home network terminal in real time, so that the video content can be displayed through the digital terminal that does not support video conferences. Moreover, when a user gets home, a mobile phone terminal involved in the video conference can conveniently switch the images to a television terminal, thus not needing to be held by the user. Therefore, user experience is improved.

Claims

1. A method of sharing audio and/or video, comprising:

writing, by a first terminal, audio and/or video from an audio-video providing module into a cache space, according to a play request of a second terminal, and transmitting the audio and/or video stored in the cache space to the second terminal.

2. The method according to claim 1, wherein the step of writing the audio and video from the audio-video providing module into the cache space by the first terminal comprises:

synchronizing, by the first terminal, the audio-video according to time stamp information in a code stream of an audio and video Real-time Transport Protocol (RTP), and writing the synchronized audio-video into the cache space frame by frame.

3. The method according to claim 1, wherein the step of writing the audio and/or video from the audio-video providing module into the cache space by the first terminal comprises:

when the cache space is full, stopping writing data into the cache space by the first terminal; and

when the cache space is not full, continuing writing the data into the cache space by the first terminal.

4. The method according to claim 1, wherein the step of transmitting the audio and/or video stored in the cache space to the second terminal by the first terminal comprises:

stopping transmitting the audio and/or video stored in the cache space to the second terminal, when the first terminal determines that an occupied space of the cache space is no greater than a set threshold, until the occupied space of the cache space is greater than the set threshold, and then continuing transmitting the audio and/or video stored in the cache space to the second terminal.

5. The method according to claim 1, wherein the first terminal is a mobile terminal, the second terminal is a home digital terminal, and the audio-video providing module is a video conference server.

11. The method according to claim 2, wherein the step of transmitting the audio and/or video stored in the cache space to the second terminal by the first terminal comprises:

stopping transmitting the audio and/or video stored in the cache space to the second terminal, when the first terminal determines that an occupied space of the cache space is no greater than a set threshold, until the occupied space of the cache space is greater than the set threshold, and then continuing transmitting the audio and/or video stored in the cache space to the second terminal.

12. The method according to claim 3, wherein the step of transmitting the audio and/or video stored in the cache space to the second terminal by the first terminal comprises:

stopping transmitting the audio and/or video stored in the cache space to the second terminal, when the first terminal determines that an occupied space of the cache space is no greater than a set threshold, until the occupied space of the cache space is greater than the set threshold, and then continuing transmitting the audio and/or video stored in the cache space to the second terminal.

13. The method according to claim 2, wherein the first terminal is a mobile terminal, the second terminal is a home digital terminal, and the audio-video providing module is a video conference server.

14. The method according to claim 3, wherein the first terminal is a mobile terminal, the second terminal is a home digital terminal, and the audio-video providing module is a video conference server.

6. A system for sharing audio and/or video, comprising a first terminal, a second terminal and an audio-video providing module, wherein

the first terminal is configured to write audio and/or video from the audio-video providing module into a cache space according to a play request of the second terminal, and to transmit the audio and/or video stored in the cache space to the second terminal.

7. The system according to claim 6, wherein the first terminal writing the audio and video from the audio-video providing module into the cache space comprises:

the first terminal synchronizing the audio-video according to time stamp information in a code stream of an audio and video Real-time Transport Protocol (RTP), and writing the synchronized audio-video into the cache space frame by frame.

8. The system according to claim 6, wherein the first terminal writing the audio and/or video from the audio-video providing module into the cache space comprises:

when the cache space is full, the first terminal stopping writing data into the cache space; and

when the cache space is not full, the first terminal continuing writing the data into the cache space.

9. The system according to claim 6, wherein the first terminal transmitting the audio and/or video stored in the cache space to the second terminal comprises:

the first terminal stopping transmitting the audio and/or video stored in the cache space to the second terminal, when the first terminal determines that an occupied space of the cache space is no greater than a set threshold, until the occupied space of the cache space is greater than the set threshold, and then continuing transmitting the audio and/or video stored in the cache space to the second terminal.

10. The system according to claim 6, wherein the first terminal is a mobile terminal, the second terminal is a home digital terminal, and the audio-video providing module is a video conference server.

15. The system according to claim 7, wherein the first terminal transmitting the audio and/or video stored in the cache space to the second terminal comprises:

the first terminal stopping transmitting the audio and/or video stored in the cache space to the second terminal, when the first terminal determines that an occupied space of the cache space is no greater than a set threshold, until the occupied space of the cache space is greater than the set threshold, and then continuing transmitting the audio and/or video stored in the cache space to the second terminal.

16. The system according to claim 8, wherein the first terminal transmitting the audio and/or video stored in the cache space to the second terminal comprises:

the first terminal stopping transmitting the audio and/or video stored in the cache space to the second terminal, when the first terminal determines that an occupied space of the cache space is no greater than a set threshold, until the occupied space of the cache space is greater than the set threshold, and then continuing transmitting the audio and/or video stored in the cache space to the second terminal.

17. The system according to claim 7, wherein the first terminal is a mobile terminal, the second terminal is a home digital terminal, and the audio-video providing module is a video conference server.

18. The system according to claim 8, wherein the first terminal is a mobile terminal, the second terminal is a home digital terminal, and the audio-video providing module is a video conference server.
