Abstract:
1. A method for constructing a frozen picture to be displayed on a display device in a video data decoding system, the method comprising the steps of: receiving video data to be spatially and temporally reconstructed in the decoding system; first determining whether a descriptor of the video data for indicating types of source material from which the video data has originated is in error; second determining whether the descriptor indicates progressive or non-progressive; sending a frame picture of the video data to display, for constructing a frozen picture when the descriptor is not in error in the first determining step and the descriptor indicates progressive in the second determining step; and sending one of a plurality of field pictures of the video data to display, for constructing a frozen picture when the descriptor is in error in the first determining step or the descriptor indicates non-progressive in the second determining step.
