Abstract: A digital augmentation system, in conjunction with extended definition television (EDTV), such as advanced compatible television (ACTV), that delivers full HDTV resolution of 675 lines per picture height (l/ph) horizontally and 800 l/ph vertically is described. At the heart of the system is a subband encoder using quadrature mirror filters (QMF) and a statistical encoder to digitally reduce the data rate requirement by a factor of 20 to 1. The system was simulated on the computer using high-detail motion sequences as test images. It is suitable for transmission over any digital link of approximately 20 Mbit/sec data rate. Results from recent experiments on improving the system's strength are also reported.
