Abstract

The invention discloses an end-to-end mobile phone real-time video transmission method based on the virtual private network. The end-to-end mobile phone real-time video transmission method based on the virtual private network aims to achieve real-time video capture and transmission services among multiple mobile phones at any time and at any place. A server of the virtual private network is mainly used for connecting mobile phone terminals or computers of different network segment IPs to the same virtual local area network, distributes an IP address to each terminal, and provides a communication tunnel specially used for video transmission. The mobile phone terminals or computers have requirements for real-time videos of a mobile capture end according to requirements, the mobile capture end receives the requirements of client ends and then begins to collect information of local videos, the information is coded and then sent to the playing client ends after being packaged, and the playing client ends carry out local playing after receiving the video data. The end-to-end mobile phone real-time video transmission method based on the virtual private network beaks through the limitation of immobility of traditional video monitoring, achieves mobile monitoring of mobile phones, can serve as a practical system of live broadcast, and has certain safety and practicability.

Description

[0001] technical field [0002] The invention belongs to the field of mobile video collection and transmission, and relates to an end-to-end real-time video transmission method. [0003] Background technique [0004] With the development of modern science and technology, especially the increasing development of computer network technology, mobile communication technology, and streaming media technology, the functions of smart phones are becoming more and more abundant. Phones, faster processing speed, and larger memory have made smart phones an indispensable part of people's lives. Basically, the work that can be done by traditional computers can also be realized on smart terminals. Coupled with the development of streaming media video transmission technology and the support of most of today's smart mobile terminals for this technology, it is possible to use mobile phones to send and receive streaming media data. [0005] In recent years, with the decrease of the price of ...
