Abstract
When film is transmitted by television, the same frame of film is used to generate both interlace television fields. This results in the information carried by the second field being temporally displaced from the original by 20 ms. This displacement gives rise to judder and double image artifacts in the received image. To overcome these defects the intermediate fields are generated from the original film frames by double sided motion compensated interpolation wherein the motion information is calculated using double sided block matching. The invention may be applied either in a television receiver or video signal decoder or in the television studio before the television signal is transmitted.
