MPEG DECODER PROVIDING MULTIPLE STANDARD OUTPUT SIGNALS
A video decoder compliant with the Advanced Television Systems Standard (ATSC) includes circuitry which, when the decoder is operated in a first mode, decodes a Main Profile, High Level (MP@HL) image to produce a high-definition video output signal and decodes a Main Profile, Main Level (MP@ML) sign...

| description | A video decoder compliant with the Advanced Television Systems Standard (ATSC) includes circuitry which, when the decoder is operated in a first mode, decodes a Main Profile, High Level (MP@HL) image to produce a high-definition video output signal and decodes a Main Profile, Main Level (MP@ML) signal to produce a standard definition video signal. In addition, when the decoder is operated in a second mode, circuitry is used which generates a standard definition image from the MP@HL signal. The video decoder includes a frequency-domain filter to reduce the resolution of the MP@HL signal when the decoder is operated in the second mode.
L'invention concerne un décodeur vidéo conforme aux normes ATSC (Advanced Television Systems Standard), comprenant un ensemble de circuits qui, lorsque le décodeur fonctionne selon un premier mode, décode une image "MP@HL" (main profile, high level) afin de produire un signal de sortie vidéo haute définition, et décode également un signal "MP@ML" (main profile, main level) afin de produire un signal vidéo de définition standard. En outre, lorsque le décodeur fonctionne selon un second mode, l'ensemble de circuits produit une image de définition standard à partir du signal "MP@HL". Le décodeur vidéo comprend un filtre dans le domaine fréquentiel, permettant de diminuer la résolution dudit signal "MP@HL" lorsque le décodeur fonctionne selon le second mode. |
