The Meridian Lossless Packing logo The Advanced Resolution logo. Meridian Lossless Packing, also known as Packed PCM (PPCM), [citation needed] is a lossless compression technique for PCM audio data developed by Meridian Audio, Ltd. MLP is the standard lossless compression method for DVD-Audio content [1] (often advertised with the Advanced Resolution logo) and typically provides about 1.5:1 ...
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]
Audio file icons of various formats. An audio file format is a file format for storing digital audio data on a computer system. The bit layout of the audio data (excluding metadata) is called the audio coding format and can be uncompressed, or compressed to reduce the file size, often using lossy compression.
The MQA system is a three-part process applied to digital audio music recordings consisting of 1) modifying and controlling the end-to-end digital filter response; [1] 2) preparing the audio for transfer to a smartphone or audio device using a lossy audio compression format with authentication; and 3) decompressing the recording for playback.

The reference implementation is released under the LGPL 2.1 and currently available in version 2.0 (as of 12/2020) [8] FFmpeg codecs – Codecs in the libavcodec library from the FFmpeg project (FFV1, Snow, MPEG-1, MPEG-2, MPEG-4 part 2, MSMPEG-4, WMV2, SVQ1, MJPEG, HuffYUV and others). Decoders in the libavcodec (H.264, SVQ3, WMV3, VP3, Theora ...
As such, the user normally does not have a H.264 file, but instead has a video file, which is an MP4 container of H.264-encoded video, normally alongside AAC-encoded audio. Multimedia container formats can contain one of several different video coding formats; for example, the MP4 container format can contain video coding formats such as MPEG-2 ...
Below is a list of broadcast video formats.. 24p is a progressive scan format and is now widely adopted by those planning on transferring a video signal to film. Film and video makers use 24p even if they are not going to transfer their productions to film, simply because of the on-screen "look" of the (low) frame rate, which matches native film.
MPEG-2 Part 3 also defines additional bit rates and sampling rates for MPEG-1 Audio Layers I, II, and III. [12] This extension is known as MPEG-2 LSF (low sampling frequencies), since the new sampling rates are one-half multiples (16, 22.05 and 24 kHz) of the sampling rates defined in MPEG-1 (32, 44.1 and 48 kHz).
