PROBLEM TO BE SOLVED: To provide an efficient method and apparatus for delivering an additional layer in an image of 15% to 30% of the bandwidth of a video stream.SOLUTION: A method includes the steps of: accepting first and second stereoscopic eye frame line images; determining a coarse image shift between the first and second images; determining an accurate image shift in accordance with the coarse image shift; forwarding one of the first and second images; and forwarding data corresponding to the accurate image shift and metadata for further processing. The method further includes the steps of: receiving a transmitted first full stereoscopic eye frame line image; obtaining a difference between the first and second images; subtracting the difference from the first image; storing the second stereoscopic eye frame line image; obtaining a shift line value from metadata included in the first full stereoscopic eye frame line image; and shifting the second stereoscopic eye frame line image to its original position in accordance with the shift value. |
