Abstract
This paper presents a method for interlaced image sequence coding for digital TV. The interlaced nature of the CCIR 601 format, which is the current standard for digital TV, is a serious drawback in most digital video codecs. In order to obtain a more efficient compression, we propose to process only the fields of one parity instead of processing the frames resulting from interlaced to progressive format change. The fields of the other parity are predicted using spatial interpolation based on the corresponding decoded fields, and the prediction error is also 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.
