  2. Audio codec - Wikipedia

    en.wikipedia.org/wiki/Audio_codec

    This can effectively reduce the storage space and the bandwidth required for transmission of the stored audio file. Most software codecs are implemented as libraries which interface to one or more multimedia players. Most modern audio compression algorithms are based on modified discrete cosine transform (MDCT) coding and linear predictive ...

  3. Audio coding format - Wikipedia

    en.wikipedia.org/wiki/Audio_coding_format

    An audio coding format [1] (or sometimes audio compression format) is a content representation format for storage or transmission of digital audio (such as in digital television, digital radio and in audio and video files). Examples of audio coding formats include MP3, AAC, Vorbis, FLAC, and Opus.

  4. List of open-source codecs - Wikipedia

    en.wikipedia.org/wiki/List_of_open-source_codecs

    This is a listing of open-source codecs—that is, open-source software implementations of audio or video coding formats, audio codecs and video codecs respectively. Many of the codecs listed implement media formats that are restricted by patents and are hence not open formats.

    en.wikipedia.org/wiki/Comparison_of_video_codecs

    Each compression specification defines various mechanisms by which raw video (in essence, a sequence of full-resolution uncompressed digital images) can be reduced in size, from simple bit compression (like Lempel-Ziv-Welch) to psycho-visual and motion summarization, and how the output is stored as a bit stream. So long as the encoder component ...

  6. Video coding format - Wikipedia

    en.wikipedia.org/wiki/Video_coding_format

    A video coding format [a] (or sometimes video compression format) is a content representation format of digital video content, such as in a data file or bitstream. It typically uses a standardized video compression algorithm, most commonly based on discrete cosine transform (DCT) coding and motion compensation .

    M2TS supports Digital 3D as multiple files in a specific file structure for encoding stereoscopic video: MVC stereoscopic data is in .ssif files in the /BDMV/STREAM/SSIF/ directory and require a respective base .m2ts file. Digital 3D in QTFF and ASF is possible, but not standard. MP4 only supports Digital 3D at the video format level. [44]

  9. Data compression - Wikipedia

    en.wikipedia.org/wiki/Data_compression

    Video compression algorithms attempt to reduce redundancy and store information more compactly. Most video compression formats and codecs exploit both spatial and temporal redundancy (e.g. through difference coding with motion compensation). Similarities can be encoded by only storing differences between e.g. temporally adjacent frames (inter ...
