METHOD AND SYSTEM FOR TRANSMITTING OVER A VIDEO INTERFACE AND FOR COMPOSITING 3D VIDEO AND 3D OVERLAYS

摘要

A system of transferring of three dimensional (3D) image data for compositing and displaying is described. The information stream comprising video information and overlay information, the video information comprising at least a 2D video stream and 3D video information for enabling rendering of the video information in 3D, the overlay information comprising at least a 2D overlay stream and 3D overlay information for enabling rendering of the overlay information in 3D. In the system according to the invention, the compositing of video plane takes place in the display device instead of the playback device. The system comprises a playback device adapted for transmitting over the video interface a sequence of frames, the sequence of frames comprising units, each unit corresponding to decompressed video information and decompressed overlay information intended to be composited and displayed as a 3D image, and a display device adapted for receiving over the video interface the sequence of frames and extracting the 3D video information and the 3D overlay information from the units and compositing the units into 3D frames and displaying the 3D frames.
