What Is a Video Decoder?
A video decoder is a device or software designed to convert digitized video data into its original analog form.
Integrated into devices like DVD players, smartphones, and televisions, video decoders play a crucial role in restoring video data to its original state. They achieve this by executing the reverse algorithm used during encoding. For instance, an MPEG-2 Decoder decompresses video data previously compressed by an MPEG-2 Encoder, restoring it to its original format.
Video decoders are characterized by their ability to convert digitized video data back into analog signals and are available in various types. The performance of a video decoder significantly impacts the quality of the video output.
