Title (EN) A DIVERSITY CONTROLLER FOR A VIDEO RECEIVER
(FR) DISPOSITIF DE COMMANDE EN DIVERSITE POUR UN RECEPTEUR VIDEO
Abstract:
(EN) A diversity controller (5) for a video receiver (10) includes a beamforming network (3) that combines received video signals at two or more antennae to provide a plurality of antennae combination signals. A high speed RF switch (4) is responsive to a received signal quality measure for asynchronously coupling one of the plurality of antennae combination signals to the video receiver.
(FR) La présente invention concerne un dispositif de commande en diversité pour un récepteur vidéo, comprenant un réseau de formation de faisceaux qui combine des signaux vidéo reçus sur au moins deux antennes afin d'obtenir plusieurs signaux d'antennes combinés. Un commutateur RF grande vitesse réagit à la mesure de la qualité d'un signal reçu pour coupler de manière asynchrone l'un des multiples signaux d'antennes combinés au récepteur vidéo.
