Compared with the prior art (live broadcast software needs to be installed and the like), the video live broadcast method is simpler and faster to operate, and therefore user experience is improved.
Preferably, the corresponding video information is transmitted or received in a VOLTE manner.
The Voice over Long-Term Evolution (VoLTE) means a high-speed wireless communication standard for mobile phones and data terminals. It is based on an IP (internet protocol) multimedia subsystem (IMS) network, and uses profiles tailored to the Control plane (Control plane) and Media plane (Media plane) of voice services as data streams on LTE (long term evolution) for transmission in LTE data carrying networks without the need to maintain and rely on traditional circuit switched voice networks. The voice and data capacity of VoLTE is large.
Namely, a high-quality communication service is established on the 4G data link, because the communication bandwidth is remarkably improved, the voice definition is greatly improved, and simultaneously, the video call (ViLTE) can be carried.
ViLTE (Video over LTE) is an extension of VoLTE, which enhances voice services; whereas VoLTE is a prerequisite for deployment of ViLTE.
The video live broadcast method has ViLTE service capability, the video providing mode is more direct, application does not need to be installed, websites do not need to be input, the operation is simpler and faster, and therefore user experience is improved.
In addition, voLTE is used as a convenient channel of videos and can be used for realizing live video broadcast through cooperative control. The live video herein initially refers to live webvideo. The VoLTE channel has strong real-time performance and high stability, so that the transmission of video information is more stable.
Preferably, in S2411, if the user identity is a live broadcast, receiving the video information from the user side.
And S2412, processing the video information.
S2413, sending the processed video information to a playing end of the viewer.
If the user is determined to be the live broadcast, the video stream from the mobile phone is received firstly, then the video stream is processed correspondingly, and finally the video stream is prepared to be distributed to the viewers subsequently.
Preferably, in another case, S2421, if the identity of the user is the viewer, determining whether the live telecast requested by the viewer is in an activated state according to the requested live telecast number.
And S2422, if the live broadcast room requested by the viewer is in the activated state, sending video information to a playing end of the viewer.
In other words, this is for the live broadcast, and if it is determined that the user is the viewer, the video information is sent to the playing end of the viewer.
