3Dvideoihin

3Dvideoihin is a term used to describe a hypothetical or fictional approach to storing and rendering stereoscopic 3D video content. In this concept, each frame carries two main data streams: a color image and a corresponding depth map or disparity field, enabling virtual viewpoint rendering beyond the fixed camera positions.

Encoding and rendering: The format envisions metadata describing camera geometry, baseline, and convergence, allowing a renderer to synthesize left and right views or to project the scene for head-mounted displays. Color and depth streams may be compressed separately or jointly; compatibility with existing codecs (H.264/HEVC) and container formats (such as MP4 or MKV) is pursued to facilitate distribution.

History and status: The idea has appeared in speculative and academic writings and demos but is not a widely standardized format. Several proprietary implementations exist as part of research pipelines or entertainment projects; interoperability between devices and software remains limited.

Applications and limitations: Potential uses include home entertainment on 3D-capable displays, streaming to VR headsets, and telepresence. Limitations include higher data requirements, the need for depth accuracy, the absence of universal standards, and the potential for latency in real-time rendering.
