Realtidsstrømming

Realtidsstrømming, often referred to as live streaming, is a technology that allows for the transmission of video and audio content over the internet in real-time. Unlike traditional video playback, which requires a file to be downloaded in its entirety before viewing, realtidsstrømming delivers data incrementally, enabling viewers to watch content as it is being created. This process involves capturing the audio and video, encoding it into a digital format, and then transmitting it over a network to viewers.

The technology is widely used for a variety of purposes. Live events, such as sports broadcasts, concerts, and news coverage, are a primary application, allowing audiences to experience events as they happen. Online gaming platforms utilize realtidsstrømming for players to broadcast their gameplay to others, fostering communities and entertainment. Social media platforms also incorporate live streaming features, enabling individuals to share moments and interact with followers in real-time. Educational institutions and businesses use it for webinars, online lectures, and virtual meetings.

Key components of realtidsstrømming include the capture device (camera, microphone), an encoder to compress the data, a streaming server to distribute the content, and a player on the viewer's device to decode and display the stream. Latency, the delay between the original event and its appearance on the viewer's screen, is a critical factor, with lower latency being desirable for interactive experiences. Various protocols, such as RTMP and HLS, are employed to manage the transmission of data efficiently. The popularity of realtidsstrømming has grown significantly with advancements in internet speeds and mobile technology.
