Use cases and requirements for virtual and real fusion coding in metaverse applications
- Abstract
- Metaverse is an emerging research and application field with the combination of multiple technologies including digital twin, Internet of Things (IoT), digital assets, multimodal data fusion and artificial intelligence generated content (AIGC). Users need immersive experience such as playback of camera-captured 3D scenes with 6DoF of viewer position and orientation. The current video coding standard is optimized by 2D videos and the coding efficiency may not be enough. Therefore, the metaverse applications need an efficient virtual and real coding technology to support low-delay and immersive experience for users. The virtual and real coding technology can support affordable coded bit rate and high coding efficiency for immersive videos, omnidirectional videos, as well as the source content with high quality depth information. The interaction between digital human and users, online meetings, gaming, sports viewing can be the use cases benefiting from this coding technology. This Technical Specification provides the related requirements, reference model of application system and use cases of the virtual and real fusion coding in metaverse applications.
