Abstract

A method, system and mobile terminal for implementing multimedia playing are described, which includes that a mobile terminal sends multimedia stream data to be played to another-end mobile terminal via a connection established based on NFC technology, and the mobile terminal and the another-end mobile terminal decode the multimedia stream data to be played, and respectively play corresponding parts of the decoded multimedia stream data in accordance with the respective part playing mode. In this way, two mobile terminals can respectively playing part of a multimedia image based on NFC technology, a multimedia image can be clearly amplified and displayed via the splicing of mobile terminal screens, thereby helping a user quickly solve the problem that a mobile terminal screen is small and not good for amplifying and displaying the multimedia image.

First claim

What is claimed is:

1. A method for implementing multimedia playing, comprising:
sending, by a local mobile terminal, multimedia stream data to be played to another-end mobile terminal via a connection established based on Near Field Communication (NFC) technology;
decoding, by the local mobile terminal and the another-end mobile terminal, the multimedia stream data to be played, and respectively playing corresponding parts of the decoded multimedia stream data in accordance with part playing modes respectively set by the local mobile terminal and the another-end mobile terminal; and
achieving, by the local mobile terminal and the another-end mobile terminal, multimedia playing synchronization according to a synchronization mechanism, wherein the achieving, by the local mobile terminal and the another-end mobile terminal, multimedia playing synchronization according to a synchronization mechanism comprises: receiving a time label of multimedia stream data currently played by the another-end mobile terminal, acquiring a time label of multimedia stream data currently played by the local mobile terminal, comparing the two time labels to determine whether a time difference exists, and if the time difference exists, performing playing time calibration on multimedia stream data played by the local mobile terminal according to the time difference; or,
receiving a time label of multimedia stream data currently played by the local mobile terminal, acquiring a time label of multimedia stream data currently played by the another-end mobile terminal, comparing the two time labels to determine whether a time difference exists, and if the time difference exists, performing playing time calibration on multimedia stream data played by the another-end mobile terminal according to the time difference.

2. The method according to claim 1 , further comprising: before the multimedia stream data to be played is sent, establishing, by the local mobile terminal and the another-end mobile terminal, the connection through the NFC technology.

3. The method according to claim 1 , further comprising: before the multimedia stream data to be played is sent, respectively setting, by the local mobile terminal and the another-end mobile terminal, the part playing modes according to user input.

4. The method according to claim 1 , wherein the multimedia stream data consists of reference frames and non-reference frames, and the decoding, by the local mobile terminal and the another-end mobile terminal comprises:
decoding reference frames completely; and
decoding non-reference frames partially, and
wherein the decoding non-reference frames partially, comprises:
decoding, by the local mobile terminal, macro-blocks within a range of a to-be-played by the local mobile terminal according to the part playing modes in reference frames; and
decoding, by the another-end mobile terminal, macro-blocks within a range of a to-be-played by the another-end mobile terminal according to the part playing modes in reference frames.

5. A system for implementing multimedia playing, comprising:
a local mobile terminal, configured to send multimedia stream data to be played to a another-end mobile terminal via a connection established based on Near Field Communication (NFC) technology, decode the multimedia stream data to be played and play a corresponding part of the decoded multimedia stream data in accordance with a part playing mode set by the local mobile terminal; and
another-end mobile terminal, configured to receive multimedia stream data sent by the local mobile terminal, decode the received multimedia stream data and play a corresponding decoded part of the received multimedia stream data in accordance with a part playing mode set by the another-end mobile terminal;
wherein when the local mobile terminal implements a synchronous playing mechanism, the local mobile terminal is further configured to achieve multimedia playing synchronization with the another-end mobile terminal based on a synchronization mechanism by receiving a time label of multimedia stream data currently played by the another-end mobile terminal, acquiring a time label of multimedia stream data currently played by the local mobile terminal, comparing the two time labels to determine whether a time difference exists, and if the time difference exists, performing playing time calibration on multimedia stream data played by the local mobile terminal according to the time difference; or
when the another-end mobile terminal implements a synchronous playing mechanism, the another-end mobile terminal is further configured to achieve multimedia playing synchronization with the local mobile terminal based on a synchronization mechanism by receiving a time label of multimedia stream data currently played by the local mobile terminal, acquiring a time label of multimedia stream data currently played by the another-end mobile terminal, comparing the two time labels to determine whether a time difference exists, and if the time difference exists, performing playing time calibration on multimedia stream data played by the another-end mobile terminal according to the time difference.

6. The system according to claim 5 , wherein the local mobile terminal is further configured to set own part playing mode according to user input;
the another-end mobile terminal is further configured to set own part playing mode according to user input.

7. The system according to claim 5 , wherein the multimedia stream data consists of reference frames and non-reference frames,
the local mobile terminal is further configured to decode reference frames completely and decode non-reference frames partially, wherein decoding, non-reference frames partially, comprises: decoding macro-blocks within a range of a to-be-played by the local mobile terminal according to the part playing modes in reference frames; and
the another-end mobile terminal is further configured to decode reference frames completely, and decode non-reference frames partially, wherein decoding non-reference frames partially, comprises: decoding macro-blocks within a range of a to-be-played by the another-end mobile terminal according to the part playing modes in reference frames.

8. A mobile terminal for implementing multimedia playing, comprising:
a decoding module configured to decode multimedia stream data to be played;
a playing module configured to play a corresponding decoded part of the multimedia stream data in accordance with a part playing mode set by the mobile terminal;
a sending module configured to send multimedia stream data to be played to another-end mobile terminal via a connection established based on Near Field Communication (NFC) technology; or
a receiving module, configured to receive to-be-played multimedia stream data sent by another-end mobile terminal via a connection established based on Near Field Communication (NFC) technology; and
a synchronization module configured to achieve multimedia playing synchronization with the another-end mobile terminal according to a synchronization mechanism, wherein the synchronization module comprises: a monitoring and management module, configured to receive a time label of multimedia stream data currently played by the another mobile terminal, to acquire a time label of multimedia stream data currently played by the mobile terminal, to compare the two time labels to determine whether a time difference exists, and to, if the time difference exists, trigger a time management module to perform playing time calibration on multimedia stream data played by the mobile terminal according to the time difference; the time management module, configured to perform playing time calibration on the multimedia stream data played by the mobile terminal
