发明名称 System and method for electronically recording and playing back video images.
摘要 <p>Apparatus and method for encoding and recording electronic image information signals in a manner whereby luminance signals for odd field lines are recorded in association respectively with chrominance signals alternately selected from both the even field lines and the odd field lines and luminance signals for even field lines are recorded in association respectively with the remaining chrominance signals alternately selected from both the even field lines and the odd field lines. Chrominance samples recorded in this manner are spaced only two field lines apart thereby allowing the chrominance signals to be interpolated by a playback device specially configured to provide for increased vertical chrominance resolution. Chrominance samples recorded in this manner may also be played back with a conventional playback device, which does not provide the increased vertical chrominance resolution while such a specially configured playback device can play back chrominance samples recorded in standard format without providing the increased vertical chrominance resolution.</p>
