Problems solved by technology

Due to the use of streaming media servers, this method is as expensive to implement as the previous method
In addition, the above two methods are usually limited by the type of protocol supported, and the client also needs to support the same protocol
This limits the widespread use of dynamic image webcasting technology

Embodiment Construction

[0015] Embodiments of the present invention will now be described with reference to the drawings, in which like reference numerals represent like elements.

[0016] The implementation of the method is based on the system architecture composed of the server end and the client end. The hardware part of the server includes: a TV tuner (tuner), a camera or video camera, and an ordinary X86 personal computer. Connect the TV tuner (tuner), camera or camcorder to the common X86 personal computer host. The function of the TV tuner is to provide standard TV reception functions. The function of the camera or video camera is to monitor or capture images of people or objects within its shooting range. The X86 personal computer mainframe is selected because the memory and CPU can be easily replaced according to the video output format and video quality required by the user, which increases the flexibility of hardware selection. In this way, the present invention can encode the real-time...

Abstract

The invention discloses a file-based video live webcasting method. The method mainly comprises the following steps: when a request which is sent through hypertext transfer protocol (HTTP) by a browser is a request for watching a channel or a video on a device and the request content is legal, a coder on server end performs coded output to a video device or a record file, CGI executable program orscript transmits the message of URL of a playlist file containing the information of each coded output file, the browser analyzes the message, when the analysis result is the URL address of the codedoutput file, the browser embeds a player plug-in to one page, prepares to play the coded output file and sends a file-sending request for sending the coded output file; and a Web server sends the coded output file according to the file-sending request, and the player plug-in plays the coded output file. The method uses the standard Web server and utilizes HTTP for data transmission, thus the costfor realizing the method is lower and the communication process is not limited by protocol.

Description

technical field [0001] The present invention relates to dynamic image network live broadcasting technology, be specifically related to the dynamic image that changes in real time captured by equipment such as TV tuner (tuner), monitoring camera, video camera, or the dynamic image that is preserved by recording file such as DVD broadcasts live on the network method. Background technique [0002] The rapid development and popularization of the Internet has provided a strong market driving force for the development of streaming media services, and streaming media services are becoming increasingly popular. At present, streaming media technology is widely used in all aspects of Internet information services such as multimedia news release, online live broadcast, online advertising, e-commerce, video on demand, distance education, telemedicine, Internet radio, and real-time video conferencing. The application of streaming media technology has brought revolutionary changes to net...
