The term codec is also used as a generic name for a videoconferencing unit. A receiving device then runs the signal through a video decompressor, then a digital-to-analog converter for analog display. The second generation (HEOS HS2) supports the following file formats and extensions: Note: Files protected by DRM such as Apple’s Fairplay DRM are not supported. A video camera's analog-to-digital converter converts its analog signals into digital signals, which are then passed through a video compressor for digital transmission or storage. Another possible reason is that the audio codec is unsupported. Codecs are used in videoconferencing, streaming media and video editing applications. The most likely reason you see a can't open file, unsupported audio codec, or unsupported video format' error is because your current media player doesn’t support the codec of your video file. In practice, however, "codec" is sometimes used loosely to refer to formats.Ī codec encodes a data stream or signal for transmission, storage or encryption, or decodes it for playback or editing. A codec should not be confused with a coding or compression format or standard – a format is a document, a way of storing data, while a codec is a program which can read or write such files. The word codec is a portmanteau of "coder-decoder" or, less commonly, "compressor-decompressor".
