Abstract
In TV stations, progressive scanning and HDTV system are used recently. However, standard TV receiver is still used mainly at home. We suppose a broadcast system which use 480p format at source picture and 480i format at receiver. At first, we discuss about suitable coding for the supposed system, and show that progressive picture coding has advantages. Then, we propose efficient method that reject redundant of picture information for 480i picture decoding. Finally, we compare the efficiency of proposed method to MPEG-2 interlaced picture coding.
