DYNAMIC CODE RATE SWITCHING METHOD, SERVER AND SYSTEM

摘要

Disclosed is a dynamic code rate switching method, comprising the following steps: a server acquires a downloading code rate of a current video fragment of a program in a server selected to download by a video playing terminal; according to the downloading code rate, dynamically adjusting the code rate of the next video fragment in the server required to download by the video playing terminal; and splicing the beginning of the next video fragment required to download by the video playing terminal and the tail of the current video fragment at the server, and generating a spliced video file for the video playing terminal to download progressively and play. Also disclosed are a server and system for dynamic code rate switching. The present invention can dynamically switch the code rate without requiring the video playing terminal and the server supporting the same dynamic code rate switching technique, thus greatly improving the compatibility between the server and various video playing terminals.
