What are the characteristics of streaming media?

Features of streaming media: 1. The content is mainly time-continuous media data, such as audio, video, animation, multimedia, etc.; 2. The content can be transmitted using streaming technology without conversion; 3. It has Strong real-time and interactivity; 4. The startup delay is greatly shortened, shortening the user's waiting time (the user does not have to wait until all the content is downloaded to the hard disk to start browsing, and can start watching after a period of startup delay) ); 5. The requirements for system cache capacity are greatly reduced.

Streaming media (streaming media), multimedia data is continuously sent to the client by the streaming media provider, and the client does not need to download the entire multimedia data locally to start playing multimedia.

Streaming media refers to a technology and process that compresses a series of media data, sends the data in segments over the Internet, and instantly transmits audio and video on the Internet for viewing. This technology allows data packets to be sent like running water. ; If this technology is not used, the entire media file must be downloaded before use. Streaming transmission can transmit live videos or videos pre-stored on the server. When a viewer watches these video files, the video data is played by specific playback software immediately after being sent to the viewer's computer.

Features of streaming media:

(1). The content is mainly time-continuous media data (audio, video, animation, multimedia, etc.).

(2). Content can be transmitted using streaming technology without conversion.

(3). It has strong real-time and interactivity.

(4). The startup delay is greatly shortened, shortening the user's waiting time; users do not need to wait until all content is downloaded to the hard disk to start browsing, but can start watching after a period of startup delay.

(5). The requirements for system cache capacity are greatly reduced.

The Internet is an asynchronous transmission based on packet transmission. Data is decomposed into many packets for transmission. Since each packet may choose a different route, the time delay to reach the user's computer will be different. In The client needs a caching system to compensate for the effects of delay and jitter and to ensure the order of data packet transmission. During the playback of streaming media files, since all files no longer need to be downloaded to the cache, the requirements for caching are very low.

The streaming media system includes the following five aspects:

• (1) Encoding tool: used to create, capture and edit multimedia data , forming a streaming media format.

• (2) Streaming media data.

• (3) Server: Stores and controls streaming media data.

• (4) Network: A network suitable for multimedia transmission protocols and even real-time transmission protocols.

• (5) Player: for clients to browse streaming media files.

Some of these 5 parts are required by the server, and some are required by the client, and different streaming media standards and solutions from different companies will differ in some aspects. .
