Title
(EN) METHOD AND DEVICE FOR TV RECEIVING AND INTERNET TRANSRECEIVING ON A SATELLITE ANTENNA
(FR) PROCEDE ET DISPOSITIF DE RECEPTION TV ET D'EMISSION-RECEPTION INTERNET SUR UNE ANTENNE SATELLITE
Abstract
(EN)
A device for receiving satellite signals, associated to a parabolic dish (2) suitable for reflecting to a corresponding focus a first signal (25) at a first frequency and a second signal (35) at a second frequency. The device comprises a first feed (7,8) arranged near the focus suitable for transducing the first signal and transmitting it to a first receiver (9), a second feed (40,40a,40b) arranged near the focus suitable for transducing the second signal (35,35a,35b) and transmitting it to a second receiver. The first frequency is dedicated to TV channels and the second frequency is at a band different from the first frequency and is dedicated to internet transmissions. The feeds can be of double reflection type, comprising a reflecting plate (7) that directs signals already reflected from the parabolic dish (2) towards a tubular wave guide (8) co-axial to the parabolic dish as well as towards a dipole (40) that constitutes the second feed. This way a simultaneous TV receiving and internet transreceiving on a same satellite antenna can be effected on a same satellite antenna using a single feed device.
(FR)
L'invention concerne un dispositif pour recevoir des signaux satellites, associé à une antenne parabolique (2), pouvant réfléchir, vers un foyer correspondant, un premier signal (25) à une première fréquence et un deuxième signal (35) à une deuxième fréquence. Ce dispositif comprend une première alimentation (7,8) placée à proximité du foyer, pouvant convertir le premier signal et le transmettre à un premier récepteur (9), une deuxième alimentation (40,40a, 40b) placée à proximité du foyer, pouvant convertir le deuxième signal (35,35a, 35b) et le transmettre un deuxième récepteur. La première fréquence est affectée aux canaux TV et la deuxième fréquence se trouve dans une bande différente de la première fréquence et est affectée aux transmissions Internet. Les alimentations peuvent être du type à double réflexion, comprenant une plaque réfléchissante (7) qui dirige les signaux déjà réfléchis par l'antenne parabolique (2) vers un guide d'ondes tubulaire (8) coaxial à l'antenne parabolique et vers une antenne dipôle (40) qui constitue la deuxième alimentation. Ainsi, une réception TV et une émission-réception Internet peuvent être effectuées simultanément sur une même antenne satellite au moyen d'un seul dispositif d'alimentation.
