Abstract:
1. A method for video processing, the method comprising: in a video processing system: separating each frame of a progressive video stream into an even-indexed line picture and an odd-indexed line picture; generating first and second interlaced video sequences from the progressive video stream by: combining even-indexed lines of the even-indexed line picture obtained from a frame of the progressive video stream with odd-indexed lines of the odd-indexed line picture obtained from an adjacent frame of the progressive video sequence stream to form a picture in a first interlaced video sequence, the first interlaced video sequence comprising a plurality of pictures; and combining odd-indexed lines of the even-indexed line picture obtained from the frame of the progressive video stream with even-indexed lines of the odd-indexed line picture obtained from the adjacent frame of the progressive video stream to form a picture in a second interlaced video sequence, the second interlaced video sequence comprising a plurality of pictures; and transmitting said generated first and second interlaced sequences to a decoder for restoration of the progressive video stream for display in progressive format.
