An Internet-based secure video conferencing system and method

Abstract

A secure video conferencing system and method based on the Internet. The system includes a video sending equipment terminal, a server and a video receiving equipment terminal. The video sending equipment terminal collects audio data, video data and text data, and converts the audio data into audio in WAV format. data, convert the video data into YUV format video data, encode and encrypt it, encapsulate and transmit it to the server, and transmit the text data directly to the server through the Socket socket protocol; the server stores audio data, video data and text data, and at the same time Transmit it to the video receiving equipment terminal for playback; the video receiving equipment terminal synchronously decapsulates the audio data and video data, decodes and decrypts them, and plays the decoded audio data and video data synchronously, and at the same time, the text data is show.

Description

technical field [0001] The invention belongs to the security application field of multimedia technology, and in particular relates to an Internet-based security video conferencing system and method. Background technique [0002] With the rapid development of Internet technology, multimedia technology, especially video technology, is widely used in real life. With the advancement of digital technology, many European countries began to study digital TV technology at the end of the 20th century. With the rapid development of digital TV technology and the widespread popularity of the Internet around the world, various digital video compression coding standards have emerged as the times require. . In 1993, the introduction of the MPEG-4 standard, a low-bit-rate, high-quality audio and video compression coding scheme, further promoted the development of network video technology. In 2003, H.264, a digital video coding standard released by the joint video group of ITU-T Video Codi...

AI Technical Summary

Problems solved by technology

There are three main reasons for this phenomenon: First, domestic video communication has been occupied by instant messaging software such as QQ, and the video conferencing system lacks the concept of interaction and community, and its functions are relatively simple and one-sided; With expensive hardware cost as technical support, however, the most ideal hardware cost in daily life is only PC and camera, so unless there is an urgent need, the existing video conferencing system wants to enter the market and be popularized in the family and personal fields In addition, the existing video conferencing system has many hidden dangers in terms of security, and the effective way to improve the security of the system is to sacrifice the increase in transmission bandwidth, so as to achieve the goal of increasing the complexity of encryption, and according to According to the statistics of the average connection speed of the global network in the fourth quarter of 2011, the average connection speed of mainland my country ranks only 90th in the world, and the scheme of improving system security at the expense of bandwidth is fundamental in my country's existing network environment. Therefore, building a system that can provide a community-oriented safe video conference for the public is of great significance to the development and promotion of video conference systems in my country
