Embodiment Construction
[0056] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0057] figure 1 It is a flowchart of a video data transmission method provided by an embodiment of the present invention, see figure 1 , the example includes:
[0058] 101: The second communication device receives a video call request sent by the first communication device, where the video call request carries media capability information of the first communication device;
[0059] Wherein, both the first communication device and the second communication device may be devices with communication capabilities.
[0060] The media capability information of the first communication device includes at least an audio call frequency. Further, the media capability information of the first communication device may further include an audio call ...

The invention discloses a video data transmission method, device and communication equipment, belonging to the field of terminals. The method includes: the second communication device receives a video call request sent by the first communication device; judging whether the media capability information of the first communication device matches the media capability information of the second communication device; when the second When the media capability information of the communication device does not match the media capability information of the first communication device, and the media capability information of the second communication device and the media capability information of the first communication device contain the same audio call frequency, create a session description Protocol SDP response message, sending the SDP response message to the first communication device, so that the first communication device and the second communication device transmit video data. The invention enables video data to be transmitted between the first communication device and the second communication device by constructing an SDP response message.
Description
technical field [0001] The present invention relates to the field of terminals, in particular to a video data transmission method, device and communication equipment. Background technique [0002] With the development of terminal data services, there are more and more packet domain data services. Video calls are one of the typical packet domain data services. How to ensure the normal transmission of video data has become the focus of the industry. [0003] In the prior art, when A calls B, A sends a video call request to B, and the video call request carries A's media capability information, and the media capability information includes A's audio call frequency and video call frequency, when When B receives the video call request sent by A, it matches A's media capability information according to B's media capability information. When B's media capability information and A's media capability information contain the same audio call frequency, B's media capability information ...
