Terminal, cache server and method and apparatus for acquiring video slices

Abstract

The invention discloses a terminal, a cache server and a method and apparatus for acquiring video slices, relating to the technical field of information and reducing the time delay for playing the video slices. The method includes, firstly, according to the triggering condition of an acquired video slice, determining the video slice that a terminal needs to acquire as an Nth video slice of a video file, acquiring the video index information of the video file from a cache server, determining the downloading address of the Nth video slice according to the download rate of the terminal and the video index information, sending a request message for acquiring the video slice to the cache server, wherein the request message for acquiring the video slice includes the downloading address of the Nth video slice, and at the end, receiving the Nth video slice returned by the cache server. According to the method, the source-returning probability of the cache server can be effectively reduced, and the time for the terminal to obtain the video slice is reduced.

Description

technical field [0001] The present invention relates to the field of information technology, and in particular, to a terminal, a cache server, and a method and device for acquiring video slices. Background technique [0002] The HyperText Transfer Protocol Streaming (full name in English: HyperText Transfer Protocol Streaming, English abbreviation: HTTP Streaming) protocol is a streaming media transmission protocol based on the Hypertext Transfer Protocol. And can generate video index information and video segments, so that the video file can be played smoothly, wherein the video index information includes: main file information and sub-file information. Wherein, the main file information includes download addresses of sub-file information of different bit rates corresponding to the video file, and the sub-file information includes download addresses of different video segments of the video file under the bit rate. [0003] At present, a method for obtaining video segments,...

Problems solved by technology

[0004] However, when obtaining video fragments through the existing technology, the terminal requests the video fragment from the cache server. Since the video fragment may not be stored in the cache server, it needs to request and obtain the video fragment from the source station, and then obtain the video fragment. The received video fragments are sent to the terminal, which increases the time for the terminal to obtain the video fragments, resulting in a longer delay for the terminal to play the video fragments
