Abstract :
A compatible coding scheme for, interlaced HDTV is proposed. It provides a standard definition signal and a second channel containing the additional information required to reach the HD resolution. The global scheme is of the pyramidal type: the standard TV signal is obtained by downsampling the HDTV signal. The former is then coded, decoded, and upsampled. It is used to predict the HD signal, and the prediction error is coded in a second channel. In each channel, motion-compensated hybrid discrete cosine transform (DCT), coding is used, and the DCT is taken within the frame
