Paper Abstract

A method for interlaced image sequence coding for digital TV is presented. In order to obtain a more efficient compression, only the fields of one parity are compressed instead of compressing the frames resulting from interlaced to progressive format change. The fields of the other parity are predicted using spatio-temporal interpolation based on the corresponding decoded fields, and the prediction error is coded and transmitted. In this way, the decoder can reconstruct the odd and even parity fields with a reduced transmission cost. Experimental results, where the proposed interlaced coding method is applied to Gabor-like wavelet transform coding of MPEG2 image sequences, show a very good performance of the proposed scheme.
