Nokia details VVC multiview streaming with independent subpictures

Key Takeaways

• Nokia describes a single-player multiview model where the player fetches selected camera feeds and combines them into one video bitstream for a single decoder.
• Each camera feed is encoded independently with a dedicated VVC encoder, then merged as independent subpictures into a conforming VVC bitstream.
• The blog says VVC needs only high-level parameter-set changes for merging, while HEVC tile merging can require rewriting coded video data such as slice headers.
• Nokia cites the VVC packaging format in MP4 files and its merge base track feature as a way to implement multiview without parsing or writing VVC syntax.
• The same VVC approach is listed for picture-in-picture replacement, cloud-based multi-point video mixing, viewport-dependent 360-degree streaming, and stereoscopic 3D video.
