Abstract

The disclosure discloses a method, an apparatus and a system for transmitting multimedia data by bluetooth and real-time playing, wherein the method includes: a bluetooth apparatus at a transmitting terminal encodes multimedia files to be transmitted, and converts them into stream media files; the bluetooth apparatus at the transmitting terminal transmits the stream media files to a bluetooth apparatus at a receiving terminal through an Object Push Profile (OPP); the bluetooth apparatus at the receiving terminal plays the received stream media files. It is because the bluetooth apparatus at the transmitting terminal transmits the stream media files through the OPP and the bluetooth apparatus at the receiving terminal receives and plays them, and then the waiting time for playing is reduced. It is solved the problem in the prior art that audio or video playing can be carried out only after the completion of the transmission by bluetooth and the waiting time is longer.

the step of playing the received stream media files comprises;

putting the received stream media files into a buffer of the bluetooth apparatus at the receiving terminal by the bluetooth apparatus at the receiving terminal; and

taking out the stream media files from the buffer of the bluetooth apparatus at the receiving terminal and playing them by the bluetooth apparatus at the receiving terminal.

3. The method according to claim 2, further comprising:

when time for the bluetooth apparatus at the receiving terminal to store the stream media files in the buffer of the bluetooth apparatus at the receiving terminal reaches a threshold, prompting a user whether to play the stream media files, and taking out the stream media files from the buffer of the bluetooth apparatus at the receiving terminal to play when the user selects to play;

prompting the user whether to store the stream media files by the bluetooth apparatus at the receiving terminal when transmission of the stream media files is completed.

4. The method according to claim 3, wherein when a size of the stream media files stored in the buffer of the bluetooth apparatus at the receiving terminal reaches a threshold, the bluetooth apparatus at the receiving terminal prompts the user whether to play the stream media files, and clear data stored in the buffer of the bluetooth apparatus at the receiving terminal when the user selects not to play and following stream media files are transmitted abnormally;

and

the bluetooth apparatus at the transmitting terminal clears data stored in the buffer of the bluetooth apparatus at the transmitting terminal and stops encoding when determining there is a transmission abnormity.

5. The method according to claim 4, further comprising:

prompting the user whether to store the stream media files or whether to store and play the stream media files by the bluetooth apparatus at the receiving terminal when the user selects not to play and the transmission of the stream media files is completed.

6. The method according to claim 3, further comprising:

clearing data stored in the buffer of the bluetooth apparatus at the receiving terminal and stopping playing them by the bluetooth apparatus at the receiving terminal, when the bluetooth apparatus at the receiving terminal determines following stream media files have a transmission abnormality during playing the stream media files;

clearing data stored in the buffer of the bluetooth apparatus at the transmitting terminal and stopping encoding by the bluetooth apparatus at the transmitting terminal when the bluetooth apparatus at the transmitting terminal determines the stream media files have a transmission abnormity.

7. A bluetooth apparatus at a transmitting terminal, comprising an encoder and a bluetooth module at the transmitting terminal, wherein

the encoder is configured to encode multimedia files to be transmitted and convert them into stream media files;

and

the bluetooth module at the transmitting terminal is configured to transmit the stream media files to a bluetooth apparatus at a receiving terminal through an Object Push Profile (OPP).
