Title: Two-way communication system utilizing small C-band antenna for downlink and L-band for uplink
Inventor: LUSIGNAN BRUCE B
IPC: H01Q21/28
Filed: 1998-02-21
Granted: 2000-10-01
Abstract: A low data rate L-band transmitter and antenna is combined with a high data rate C-band receiver and antenna to link to a C-band transmitter and an L-band receiver on a geosynchronous orbiting satellite. This combination provides a surprising number of applications. The L-band and C-band equipment is located within the same hub station, which receives incoming signals from L-band receivers and transmits data to the C-band input data ports. The ""land"" side of the equipment is connected to data banks in the hub, to fiber or microwave links to the city networks, or to other satellite links to foreign destinations. The data stream coming down with the DVB signals carries packets used to manage responses solicited from remote users. This data stream received from the C-band DVB data stream enables each user periodically to originate a data request. The data request is transmitted at the indicated time by the user's L-band transmitter. This is received back at the hub station and interpreted by the processor. For small data packets the message will be returned through the DVB data stream with a packet addressed to the user. Voice to the user is time division multiplexed on the DVB channel, and is single channel per carrier on the L-band. Each 5 MHZ DVB channel can carry about 500 10 kbit/sec cellular digital voice channels. The receive antenna comprises a three parabolic dish design receiving vertical and horizontal polarizations from the satellite. The L-band transmit antenna is wire Y agi antenna-either one or two antennas mounted between the circles. The L-band uses the structure of the C-band antenna to point it at the targeted satellite.

Abstract: A device and method of transforming the color space signal which transforms the digital YCbCr luminiance-chrominance color space signal into digital RGB color space signal. The device gets the linear combination including the preset item and the compensation item according to the standard transformation program including four initial chrominance color items. Among which, a preset code generator produces a preset transformation code such that the preset transformation code corresponds to the first chrominance color space signal at first time sequence and corresponds to the second chrominance color space signal at second time sequence; and a compensation code generator produces a compensation transformation code that corresponds to the first chrominance color space signal at the first time sequence and to the second chrominance color space signal at the second time sequence. The preset transformation code from preset code generator and the compensation transformation code from compensation code generator are the transformation value of the preset item and the compensation item, respectively. Linear combination is used on them to get the transformation value of initial chrominance color item. The transformation value of the initial chrominance color is combined with luminiance color space signal based on a standard transformation program to get the RGB color space signal. So this device and method of transforming color space only uses the multiplier or look-up tables in the preset code generator and the compensation code generator, which enables it to reduce the cost with a simplified structure.
