Embodiment 1

[0025] Such as figure 1 As shown, it is a schematic flowchart of a method for sending and playing multimedia data in Embodiment 1 of the present invention, and the method includes the following steps:

[0026] Step 101: When playing multimedia, the source terminal reads multimedia data from the playing buffer.

[0027] It should be noted that the source terminal in the first embodiment is a data sending terminal with the function of creating a mobile TV channel and selecting and setting a mobile TV transmission method according to the created mobile TV channel to send multimedia data. The terminal can be a computer loaded with the above functions, MP4, TV, smart phone, CMMB (China Mobile Multimedia Broadcasting) terminal, TDCMMB terminal and other terminals in various forms.

[0028] Specifically, the multimedia data played by the source terminal may be TV broadcast programs, streaming media programs or locally stored audio and video multimedia data obtained by the source ter...

Embodiment 2

[0055] Such as figure 2 As shown, it is a schematic structural diagram of a terminal for sending multimedia data in Embodiment 2 of the present invention, and the terminal includes: a multimedia playing module 11 , a data reading module 12 and a data sending module 13 .

[0056] The multimedia playing module 11 is used for playing multimedia; specifically, the played multimedia data may be TV broadcast programs, streaming media programs or locally stored audio and video multimedia data obtained from the network side.

[0057] Specifically, when playing multimedia, the multimedia playing module 11 needs to use the decoding capability of the multimedia player to send the decoded audio and video multimedia data to the playing buffer, and play them sequentially according to the synchronization mechanism.

[0058] The data reading module 12 is used to read multimedia data from the playback buffer; specifically, the data reading module 12 can read the multimedia data in the playbac...

Embodiment 3

[0067] Such as image 3 As shown, it is a schematic structural diagram of a terminal for receiving and playing multimedia data in Embodiment 3 of the present invention, and the terminal includes: a data receiving module 21 and a multimedia playing module 22 .

[0068] The data receiving module 21 is used to receive the multimedia data according to the set mobile phone TV transmission mode; specifically, the data receiving module 21 scans in real time, searches transmission parameters such as transmission frequency points set by the source terminal, The multimedia data sent by the source terminal is received.

[0069] The multimedia playing module 22 is used for playing the received multimedia data; specifically, the multimedia playing module 22 is used for correspondingly demodulating, demultiplexing, decoding, etc. the received multimedia data After the operation, the multimedia data is played.

[0070] It should be noted that the terminal functions described in Embodiment ...

Abstract

The invention discloses a multimedia data transmitting method and device and a multimedia data processing system. When a source terminal conducts multimedia playing, multimedia data are read from a playing buffering area, and the read multimedia data are sent out to be received and played by a destination terminal according to a set mobile television transmission mode. By means of the scheme, any multimedia resource played by the source terminal can be sent to the destination terminal through the set mobile television transmission mode, the multimedia resource can be shared by the destination terminal, and the effects that sharable audio / video resources are expanded and audio / video transmission scenes are effectively expanded are achieved.

Description

technical field [0001] The invention relates to the field of multimedia technology, in particular to a method, device and multimedia data processing system for sending multimedia data. Background technique [0002] At present, as the number of mobile users continues to increase, the popularity of smart phones among mobile users is getting higher and higher, and the scale of smart terminals with mobile TV receiving functions is getting larger and larger. The business demand for using smart terminals to receive and play multimedia resources is also growing. [0003] Taking the mobile TV service as an example, at present, smart terminals mainly receive and play mobile TV audio and video program data in the following ways to complete the mobile TV service: [0004] The smart terminal initiates a mobile TV service request to the base station as the source of the audio and video program data, and the base station responds to the mobile TV service request, compresses the audio and...
