Streaming media refers to the simultaneous transmission of video, audio, and data from a source to a destination, where it can be received as a continuous, real-time stream. Here, the source refers to the server-side application, while the destination, or receiver, refers to the client-side application.
A key characteristic of streaming media is its time sensitivity, which is essential for applications with high real-time requirements, making them inextricably linked to streaming media. The implementation of streaming media primarily depends on improvements in network bandwidth and compression algorithms. With advancements in network protocols, network infrastructure, and compression technologies, the implementation of streaming media has become increasingly easier.
The streaming process generally works as follows: After a user selects a streaming service, the web browser and web server exchange control information using HTTP/TCP to retrieve the real-time data to be transmitted from the raw data. Then, the web browser on the client machine starts the A/V Helper program, using HTTP to retrieve relevant parameters from the web server to initialize the Helper program. These parameters may include directory information, the encoding type of the A/V data, or the server address related to A/V retrieval. The process is the same when using a high-definition video SDI encoder.
Streaming requires a suitable transport protocol. Because TCP incurs significant overhead, it is not well-suited for transmitting real-time data. In streaming implementations, HTTP/TCP is typically used to transmit control information, while RTP/UDP is used to transmit real-time audio data.
The rapid development and widespread adoption of the Internet have provided a strong market impetus for the development of streaming media services, which are also becoming increasingly popular. Streaming media capture card technology has been used in various Internet information services, including multimedia news releases, online live streaming, online advertising, e-commerce, video-on-demand (VOD), distance education, telemedicine, remote monitoring, internet radio, real-time video conferencing, large screens, and company information dissemination.
