Video data transmission method and system

Abstract

The invention discloses a video data transmission method. The method comprises the following steps: receiving a client request for transmitting a video clip, wherein the request carries a network bandwidth parameter; regulating the video data size of the video clip according to the network bandwidth, so that the video data size matches the detected network bandwidth parameter; and transmitting the regulated video clip to the client. The invention also provides a video data transmission system, which comprises a client and a video server, wherein the client transmits a request for distributing the video clip and provides the network bandwidth information to the video server; and the video server regulates the video data size of the video clip according to the network bandwidth information so that the video data size matches the network bandwidth parameter, and transmits the regulated video clip to the client. The invention can transmits video data after self-adapting to the network bandwidth, thereby maximally ensuring the fluent playing of the video. In addition, in the distribution process, partial contents in a video file is transmitted each time, thereby simplifying the file management.

Description

technical field [0001] The invention relates to the technical field of network communication and multimedia, in particular to a video data transmission method and system.

Problems solved by technology

[0005] Although the above-mentioned several protocols and the specific methods of utilizing these protocols solve the purpose of reducing traffic and adaptive bandwidth in practice, they also bring some disadvantages at the same time, such as low efficiency, and the need to prepare multiple video clip files and multiple copies. A copy of the video (fragment) file; management is inconvenient, and multiple video clip files and their copies need to be managed synchronously; it is not suitable for the current content delivery network (CDN, Content Delivery Network) architecture
