A method and device for streaming media on demand based on cloud storage

Abstract

The invention discloses a streaming media on-demand method and device based on cloud storage: RJ-FAC receives a streaming media file on-demand request, which carries a streaming media file ID and on-demand parameters; RJ-FAC reads the corresponding request from a database according to the streaming media file ID The descriptive information of all file fragments in the system, and search for the descriptive information of the target file fragments according to the on-demand parameters; RJ‑FAC reads the storage information of all corresponding file fragments from the FLR according to the streaming media file ID, and performs fragmentation according to the target files According to the description information of the target file, RJ‑FAC searches for the storage information of the target file segment; RJ‑FAC reads the data of the target file segment from the FAS according to the found storage information of the target file segment. Through the present invention, under the condition that the network bandwidth and system resources on the network side are limited, fast jumping of streaming media on demand can be realized.

Description

technical field [0001] The invention relates to computer network technology, in particular to a cloud storage-based streaming media on-demand method and device. Background technique [0002] With the integration of telecommunication services and Internet services, audio and video audiovisual services are becoming more and more popular, service forms are also diverse, and content information is also growing explosively. Due to changes in user requirements, the number of multimedia information files has increased rapidly, and at the same time, the file size has also increased by hundreds or even thousands of times in the past. In response, more and more multimedia files are stored in cloud storage systems such as distributed file systems. [0003] On the other hand, the streaming media playback system is one of the main forms of Internet multimedia applications, and it is a system for real-time download and playback through the network. With the continuous improvement of the...

Problems solved by technology

[0004] Generally, in order to accurately calculate the exact position of the part to be jumped to in the streaming media information, the streaming media on-demand jump service requires the terminal to go through a lot of calculations and interact with the streaming media server multiple times, and the streaming media server needs to read a large number of caches. Completed, if the network status is not good, there are too many concurrent access users, the file is too large, etc., it will cause multiple cache waits

This makes the user wait for a long time to jump, which brings a bad user experience to the user; at the same time, when performing the jump in online playback, it needs to interact with the server multiple times, which wastes system resources on the network side

[0005] Therefore, limited by the processing capabilities of network bandwidth and system resources on the network side, new challenges are posed to whether terminal players such as PCs and mobile phones can also achieve fast jumps during online playback.
