MPEG-I Audio seeks to provide an immersive virtual audio and visual experience to users wearing a head-mounted visual display (HMD) with audio headphones, or using loudspeakers. The user’s view and perception of the virtual reality environment (VR) is responsive to user motion (i.e. position and orientation), where the user is free to move around in […]

In October 2020, MPEG completed development of its ISO/IEC 23090-9 Geometry-based Point Cloud Compression (G‑PCC) standard. G‑PCC addresses lossless and lossy coding of time-varying 3D point clouds with associated attributes such as colour and material properties. This technology is particularly suitable for sparse point clouds. ISO/IEC 23090-5 Video-based Point Cloud Compression (V‑PCC), which was completed

MPEG has issued a Call for Proposals (CfP) on Dynamic Mesh Coding, and expects to evaluate responses to this call in April 2022. A dynamic mesh sequence may require a large amount of data since it may consist of a significant amount of information changing in time. Therefore, efficient coding technologies are required to store

ISO/IEC 23001-11 specifies metadata (Green Metadata) that facilitates the reduction of energy usage during media consumption. The metadata enable means for (a) reducing decoder power consumption, (b) reducing display power consumption, (c) media selection for the joint decoder and display power reduction, and (d) quality recovery after low-power encoding. The third edition, which is currently

In July 2020, MPEG completed its development of a Video-based Point Cloud Compression (V-PCC) standard. V-PCC addresses lossless and lossy coding of 3D point clouds with associated attributes such as colors and reflectance. Point clouds are typically represented by extremely large amounts of data, which is a significant barrier for mass market applications. However, the

With the increasing complexity and sophistication of media services and the incurred media processing, offloading complex media processing operations to the cloud/network is becoming critically important in order to keep receiver hardware simple and power consumption low. Network-based Media Processing (“NBMP”, ISO/IEC 23090-8) addresses advanced media processing use cases such as network stitching for virtual reality

MPEG Scene Description will enable the creation of 6DoF experiences based on MPEG media. The Scene Description is usually a graph that describes the 3D space as a scene that includes audio and visual objects in that scene. The 3D objects are defined using MPEG media like still pictures, 2D videos, point clouds, light fields,

Haptics provide an additional layer of entertainment and sensory immersion beyond audio and visual media. The user experience and enjoyment of media content can be significantly enhanced by adding haptics to audio/video content, whether in ISO Base Media File Format (ISOBMFF) files or in media streams such as ATSC 3.0 broadcasts, streaming games, and mobile
