Abstract

The invention is applicable to the technical field of communication, and provides a multimedia data sharing method and device. A terminal is provided with a wifi module which supports a direct connection protocol. The method comprises the following steps: a detection request message is sent; a detection reply message and a connection request message are received; whether a connection reply message is sent to a second terminal is decided according to the received detection reply message and the connection request message; when the connection reply message is sent, master-slave connection is established with the second terminal for operational capacity negotiation, and point-to-point session connection is established for multimedia data transmission. According to the multimedia data sharing method and device, the wifi module which supports the direct connection protocol is used, by means of extending the detection request message and the other messages in a P2P extension package, the master-slave connection is established with the second terminal for operational capacity negotiation, the point-to-point session connection is established for multimedia data transmission, and therefore transmission and sharing of multimedia files can be realized with no need for support from a router and too much cost.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a method and device for sharing multimedia data. Background technique [0002] With the popularity of smart phones, smart TVs and smart watches, file and multimedia file sharing has become a trend. In the prior art, the sharing of multimedia data must be supported by routers, and multimedia sharing cannot be directly realized. The patent with the publication number CN103259861A is For example, this patent discloses a method and system for recording and watching network video. This patent utilizes a router to download and save network video files provided by a network video server. The network terminal on the LAN side uses the files in the router memory to watch and download the video. Then for network terminal users to watch and use the idle computing resources of the router to record network video, which does not occupy the computing resources of the network te...
