Embodiment 1

[0039] This embodiment is based on streaming transmission, and the streaming transmission mode is first introduced below.

[0040] The process of streaming is generally as follows:

[0041] 1. After the user selects a streaming media service, the Web browser and the Web server use HTTP / TCP to exchange control information, so as to retrieve the real-time data that needs to be transmitted from the original information;

[0042] 2. The web browser starts the audio and video client program, and uses HTTP to retrieve relevant parameters from the web server to initialize the audio and video client program. These parameters may include directory information, the encoding type of audio and video data or the server address related to audio and video retrieval;

[0043] 3. The audio and video client program and the audio and video server run the real-time streaming protocol to exchange control information required for audio and video transmission. The real-time streaming protocol provid...

Embodiment 2

[0058] Based on the above-mentioned first embodiment, this embodiment provides a preferred recording method, which can set recording permissions for local users, and only authenticated users can locally record the played content, which facilitates user management.

[0059] refer to figure 2 , which is a flowchart of a method for recording streaming media according to Embodiment 2 of the present invention.

[0060] Step 201, receiving streaming media packets in real time;

[0061] Step 202, verify whether the local has the recording authority, if yes, go to Step 203; if not, go to Step 204;

[0062] Based on the needs of some practical applications, this function of recording the played content locally is not open to all clients. The audio and video server sets the recording permission for each client, and the client can obtain this permission only if it meets certain conditions (such as a VIP customer or a paying customer). The way that the audio and video server sets the ...

Embodiment 3

[0073] refer to image 3 , is a structural diagram of a network player with a recording function according to the third embodiment of the present invention.

[0074] The network player mainly includes:

[0075] The data receiving module 31 is used for receiving streaming media data packets in real time;

[0076] The cache module 32 is used to cache all received streaming media packets in the form of fragmented files locally;

[0077] The file synthesizing module 33 is used for synthesizing fragmented files into a complete streaming media file and storing it in a local storage medium.

[0078] Wherein, the data receiving module 31 receives data packets from the streaming media server in real time; the local storage medium usually refers to storage media such as hard disks; the file synthesis module 33 can synthesize the fragmented files according to the timestamps in the fragmented files for a complete streaming file.

[0079] The player may also include:

[0080] The play...
