Dekodeerimisseadmete, often referred to as decoders, are electronic devices or software programs that translate coded information into a more understandable or usable format. This process of decoding is the inverse of encoding, where data is transformed into a specific format for transmission, storage, or security.

In the realm of digital television, decoders are essential for receiving and displaying broadcast signals. These devices interpret compressed video and audio streams, such as those found in DVB (Digital Video Broadcasting) or ATSC (Advanced Television Systems Committee) standards, and convert them into signals that a television can process. Without a decoder, a digital television would not be able to display programming.

Beyond television, decoders play a crucial role in various communication technologies. For instance, in telecommunications, modems (modulator-demodulator) use decoders to interpret incoming analog signals and convert them back into digital data. Similarly, in computer networking, decoders are used to translate encoded network packets into usable data streams.

In the context of data compression, decoders are paired with encoders to reconstruct original files from compressed versions. Algorithms like JPEG for images or MP3 for audio rely on both encoding and decoding processes. Security systems also utilize decoders, particularly in cryptography, where they are used to decrypt encrypted messages or data, making them accessible to authorized users. The specific design and function of a decoder are highly dependent on the encoding method it is intended to reverse.
