<p>Apparatus for encoding a high definition multiplexed analog components television signal by decimating predetermined samples for transmission comprises separate processing paths (Figs. 17 and 18) for luminance and chrominance component signals respectively. The separately processed luminance and chrominance components signals are multiplexed into a composite signal for transmission via a skew-symmetric filter portion (1710) shared by both processing paths. A complementary skew-symmetric filter portion (1901) to the filter portion of the encoder apparatus is associated with a decoder coupled to a high definition television receiver. Predetermined samples are diagonally filtered and horizontal resolution information folded into the signal. Vertical resolution is improved through scan conversion at the receiver.</p> |
