MPEG-D is a group of standards for audio coding formally known as ISO / IEC 23003 - MPEG audio technologies, published since 2007. [1][2][3][4] MPEG-D consists of four parts: MPEG-D Part 1: MPEG Surround [5] (a.k.a. Spatial Audio Coding [6]) MPEG-D Part 2: Spatial Audio Object Coding (SAOC) [7] MPEG-D Part 3: Unified speech and audio coding [8]

MPEG-V outlines an architecture and specifies associated information representations to enable interoperability between virtual worlds (e.g., digital content provider of a virtual world, gaming, simulation), and between real and virtual worlds ( e.g., …

動態影像專家小組 （英語： Moving Picture Experts Group，簡稱 MPEG） [1] 為一源自國際標準化組織 (ISO) 與國際電工委員會 (IEC) 等國際組織的工作小組，成立於1988年，有超過300名專家一起制定影音壓縮及傳輸的規格標準。 MPEG的官方正式命名為ISO/IEC JTC 1/SC 29/WG 11 – Coding of moving pictures and audio (ISO/IEC Joint Technical Committee 1, Subcommittee 29, Working Group 11)。 該小組開發的第一個標準，為MPEG-1，是以大約1.5 Mbit/s的位元速率對 …

MPEG formats are used in various multimedia systems. The most well known older MPEG media formats typically use MPEG-1, MPEG-2, and MPEG-4 AVC media coding and MPEG-2 systems transport streams and program streams. Newer systems typically use the MPEG base media file format and dynamic streaming (a.k.a. MPEG-DASH).

The MPEG-D USAC standard (ISO/IEC 23003-3) defines the Extended High Efficiency AAC profile, which contains all of the tools of the HE-AAC v2 profile plus the mono/stereo capabilities of the Baseline USAC profile.

2024年3月25日 · MPEG-4包括视频编码（MPEG-4 Video）、音频编码（MPEG-4 Audio）以及相关的多媒体对象编码、场景描述和交互性等技术。 它支持低比特率和高压缩效率，适用于多媒体流媒体、视频通话和互联网视频等应用。

A universal dynamic range control standard that supports loudness normalization that is bitrate efficient representation of dynamically compressed versions of an audio signal. To specify how uncompressed (PCM samples) audio data can be stored.

2019年5月18日 · The official title of MPEG-D is MPEG audio technologies. Unlike MPEG-C, MPEG-D parts 1, 2 and 3 actually specify audio codecs that are not generic as MPEG-1, MPEG-2 and MPEG-4 but intended to address specific application targets. MPEG-D is composed of 5 parts, the first 4 of which are

2022年7月28日 · MPEG-D DRC（Dynamic Range Control，动态范围控制）技术可以让听者能够控制音频水平。 它可以作为每种 MPEG 音频编码技术的后处理器使用，并在播放时修改解码信号的动态范围。

This is the home page of MPEG, the group that develops standards for coded representation of digital audio, video, 3D Graphics and genomic data. Since its establishment in 1988, the group has produced standards that help industry offer end users an …
