Embodiment Construction

[0017] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0018] figure 1 The flowchart of the streaming media encryption method of the first embodiment provided by the present invention, such as figure 1 As shown, the method includes:

[0019] Step 101, the client selects at least one content segment according to at least one streaming media file provided by the server, and sends an authorization request to the server, at least one streaming media file includes at least one content segment;

[0020] The so-called streaming media refers to media formats played on the Internet / Intranet in a streaming manner, such as audio, video or multimedia files. The user does not need to download the entire file before playing the streaming media, but only stores the beginning part of the content in the memory, and caches the data packets in the computer so that the media data can be out...

Abstract

The invention relates to a streaming media encryption method. The method comprises the followings: a client selects at least one content fragment according to at least one streaming media file provided by a server and sends an authorization request to the server, and the at least one content segment is included in the at least one streaming media file; the server generates playing permission information according to the received authorization request, and sends the playing permission information to the client; the client sends a playing request to the server according to the received playing permission information; the server encrypts the at least one selected content fragment according to the playing request and the encrypted content fragment is sent to the client. The method improves the flexibility and playing efficiency of playing streaming files, and avoids the problem of speed decreasing as the internal space of the server is overused, thereby accelerating the processing speed of the server.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a streaming media encryption method. Background technique [0002] Streaming media technology is a multimedia online playback technology that has emerged in recent years. This technology uses streaming to transmit and apply multimedia on the network. When playing streaming media, the client plays while downloading, and the player does not have to wait until the entire file is downloaded locally before starting to play, but plays while downloading. The player opens up a buffer area of ​​a suitable size on the client side, and starts decoding and playing after there is enough data in the buffer area. The waiting time is saved, and the multimedia data is not directly downloaded to the local hard disk, but directly stored in the memory, and is immediately deleted by the player after playing. At present, with the increasing development of communication technology, the applicat...
