afspilning

Afspilning is the Danish term for playback, the process of reproducing audio, video, or other media from a stored or transmitted source so it can be experienced by an end user. In digital systems, afspilning is enabled by a combination of software players, hardware decoders, and rendering components that convert compressed data into audible sound and visible frames.

There are two broad categories: local playback and streaming playback. Local playback uses media files stored on a device, which are decoded and rendered by a media player. Streaming playback retrieves data over a network and renders it as it is received, potentially using adaptive streaming to adjust quality based on network conditions.

Key technical aspects include decoding via codecs, timing and synchronization of audio and video, and buffering to mitigate network or processing delays. Playback systems also manage sample rate, bit depth, frame rate, and color spaces to ensure accurate reproduction of media content.

User controls such as play, pause, stop, seek, and volume influence the experience, as do metadata handling (titles, artists, subtitles) and accessibility features. Digital rights management and licensing considerations may also affect what can be played and how it is accessed.

Afspilning is a central function in consumer electronics, computers, and mobile applications, with ongoing advances in latency, energy efficiency, and coordinated playback across devices.
