Streaming media playing method and system, server and client

Abstract

The invention discloses a streaming media playing method and system, a server and a client, and relates to the technical field of communication. The streaming media playing method comprises the stepsof encrypting a media fragment index file requested by a client and sending the encrypted media fragment index file and a secret key to the client; decrypting the encrypted media fragment index file based on the secret key by the client so as to obtain the media fragment index file; and downloading the media fragment file based on the media fragment index file and playing the media fragment file by the client. According to the streaming media playing method and system, the server and the client, as the media fragment index file URL is subjected to real-time encryption, an illegal user can be prevented from stealing an m3u8 index file; as the text content of the media fragment index file is subjected to integral encryption and decryption, the number of encryptions and decryptions for each small fragment can be reduced efficiently, the safety of the program content can be fully guaranteed, the system encryption and decryption burden can be reduced, and the performance and efficiency canbe improved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a streaming media playing method, system, server and client. Background technique [0002] Adaptive streaming media technology is a new streaming media technology emerging on the Internet in recent years, represented by Http Live Streaming (HLS for short) proposed by Apple, which can better adapt to various network environments and improve playback quality. HLS divides the video source content into multiple pieces of content with a certain length of time through the encoder, and each piece of content is set according to one or more bit rates (the bit rate is from low to high, which means that the video quality is from poor to high). to good) to encode to generate the corresponding fragments, and generate an index file in m3u8 format at the same time, recording different bit rates and the duration, file name, URL address and other information of each fragment content...

AI Technical Summary

Problems solved by technology

However, the current streaming media playback has the following disadvantages: the m3u8 index file itself is not encrypted, and the program information is easily stolen illegally when it is transmitted in plain text; an HLS program usually contains hundreds of segments, and the server needs to Encrypting and decrypting the URL address of the chip, the calculation overhead is relatively large, which affects the overall performance and efficiency of the system
