METHOD AND APPARATUS TO MARK AND IDENTIFY STEREOSCOPIC VIDEO FRAMES

摘要

A method and apparatus for encoding or tagging a video frame provides a way to indicate, to a receiver, for example, whether the video content is 3-D content or 2-D content. A method and apparatus for decoding an encoded or tagged video frame provides a way, for a receiver, for example, to determine whether the video content is 3-D content or 2-D content. 3-D video data may be encoded by replacing lines of at least one video frame with a specific color or pattern. When a decoder detects the presence of the colored or patterned lines in an image frame, it may interpret them as an indicator that 3-D video data is present.
