ümberkodeerimine

Ümberkodeerimine, often translated as re-encoding or transcoding, refers to the process of converting data from one format or encoding to another. This can apply to various types of information, including text, audio, video, and software. The primary purpose of re-encoding is to make data compatible with different systems, applications, or standards, or to optimize it for specific uses.

In the context of text, re-encoding typically involves changing character encoding schemes, such as converting from ASCII to UTF-8 or from a legacy encoding to a modern standard. This ensures that text characters are displayed correctly across different platforms and languages. For audio and video, re-encoding involves converting the file from one codec to another (e.g., from AVI to MP4, or from MP3 to AAC). This is often done to reduce file size, improve streaming performance, or ensure playback on specific devices. Software re-encoding might involve adapting a program to run on a different operating system or hardware architecture.

The process of re-encoding can sometimes lead to a loss of data quality, especially with lossy compression formats for audio and video. However, when done with appropriate settings or for lossless formats, the integrity of the original data can be preserved. Re-encoding is a fundamental operation in digital media management, data migration, and ensuring interoperability between diverse technological environments.
