Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0022] exist figure 1 In the flow chart of the first preferred embodiment of the video-on-demand method based on the local area network shown in the present invention, the video-on-demand method based on the local area network starts at step 100, proceeds to step 101 after step 100, and the server sends The fixed ports of all clients in the local area network send data packets based on the UDP protocol; then, to the next step 102, the set client obtains the IP address of the server through the data packet, and sends a feedback packet to the IP address ; Then, to next step 103, the server establish...

Abstract

The invention relates to a LAN (Local Area Network) based video-on-demand method, comprising the following steps of: S1, sending data packets based on UDP (User Datagram Protocol) protocol to fixed ports of all the clients in the LAN at set intervals by a server; S2, acquiring IP address of the server by virtue of the data packets by a set client, and sending a feedback data packet to the IP address; S3, establishing connection based on TCP (Transmission Control Protocol) protocol between the server and the client according to the feedback data packet by the server; and S4, playing video content on the server by virtue of the connected based on TCP protocol by the client used for playing videos. The invention also relates to a LAN based video-on-demand system. In the LAN based video-on-demand method and system provided by the invention, the connection between the client and the server is based on the UDP protocol, connection speed is fast, and a user of the client can watch the videos with no need of knowing IP of the server.

Description

technical field [0001] The invention relates to the field of network video-on-demand, more specifically, to a local area network-based video-on-demand method and system. Background technique [0002] With the progress and development of society, people are more and more keen on online video on demand, especially in small LANs such as Internet cafes or communities, so that there can be sufficient broadband to ensure that users can enjoy high-quality audio-visual film and television programs, but now The video on demand generally uses the client to input the IP of the server, and the client connects to the server to realize the transmission of video files between the client and the server. In this way, if the IP of the server is changed or the user of the client forgets the IP of the server, the The connection between the client and the server cannot be realized, which affects people watching videos. Contents of the invention [0003] The technical problem to be solved by t...
