The system operates with a signal transmission/reception apparatus such as a receive antenna, or a coaxial system or the like, while the antenna is receiving information signals and it operates by injecting a low power pseudo-noise digital signal into the antenna and detecting reflected energy, the magnitude of which depends on the condition of the antenna. The reflected signal is processed and compared with the original test signal to produce a digital number representing the condition of the antenna. The digital number is compared with a table of numbers in a processor to determine the condition of the antenna.

System for testing signal transmission/reception apparatus

The disclosure is of a system and method of detecting or identifying a received TV program by forming a database of identifying digital bits for a plurality of programs, processing a TV program by modulating the luminance of pairs of lines of the program and reconstituting the program with said modulated line pairs and the other components of a TV program signal. The reconstituted program is transmitted to a location at which it is decoded to recover the digital identifying bits and comparing such bits with bits in the database to identify the transmitted program.

System and method for identifying a television program

A communication system comprising a plurality of transceivers each being connected to selected ones of data inputs and at least one unidirectional antenna, each of the transceivers having a first transmitter coupled to the unidirectional antenna transmitting first signals at a first frequency to others of the plurality of transceivers according to a predetermined protocol and a first receiver coupled to the unidirectional antenna receiving second signals at a second frequency from others of the plurality of transceivers according to the predetermined protocol, the first and second frequencies being different; and a relay having an omnidirectional antenna in focused communication with the unidirectional antennas of the plurality of transceivers, a second receiver coupled to the omnidirectional antenna to receive the first signals according to the predetermined protocol and a second transmitter coupled to the second receiver and the omnidirectional antenna to convert the first signals to the second signals and to transmit the second signals to the others of the plurality of transceivers according to the predetermined protocol, each of the first and second signals including digital data combined with a pseudo-random spreading code having N bits common to all of the plurality of transceivers where N equals a predetermined number greater than two.
