Method and system for pulldown processing for 3D video

摘要

A video processing device may perform pulldown when generating an output video stream that corresponds to received input 3D video stream. The pulldown may be performed based on determined native characteristics of the received input 3D video stream and display parameters corresponding to display device used for presenting the generated output video stream. The native characteristics of the received input 3D video stream may comprise film mode, which may be used to determine capture frame rate. The display parameters may comprise scan mode and/or display frame rate. A left view or a right view frame in every group of frames in the input 3D video stream comprising two consecutive left view frames and corresponding two consecutive right view frames may be duplicated when the input 3D video stream comprises a film mode with 24 fps capture frame rate and the display device uses 60 Hz progressive scanning.
