Abstract: An antenna assembly for use particularly where relatively rapid deployment and/or disassembly of the same is required thereby making the same available to be used at a location quickly. The assembly includes a hub to which are movably mounted a bracket for attachment of an antenna, which may comprise a plurality of parts, and support legs which are movable between in use and storage positions. First and second adjustments for the azimuth and elevation of the antenna are provided for use when the antenna, bracket and support legs are in the in-use position.

Abstract: There is provided an apparatus and a method for the receipt and processing of data signals carried in a plurality of predefined frequency bands and allowing a frequency band required at an instant of time to be selected from the predefined frequency bands from which data is to be retrieved. Passing the data signals from the wanted band to a transmitter and/or receiver including first and second mixing means to process the data signals, typically using in-phase and quadrative data feeds to create a predefined representation of the wanted frequency band, to provide an output for receipt by at least one broadcast data receiver and at least the transmitter and/or receiver is provided as part of an integrated circuit rather than as separate connected components.

Abstract: The invention relates to a system, apparatus and method for the distribution of digital data signals, which are received at a receiving means, to be sent to a plurality of locations downstream therefrom, in an efficient manner. The received data is received in a first format such as an RF format with a plurality of different components and is then changed in format, in one embodiment to an optical format. The data path is also split to allow a plurality of data paths to be defined which allow the data to be transmitted along the plurality of data paths to each of the downstream locations.

Abstract: The invention relates to a system and method for the distribution and processing of data, for video and/or audio and most typically HDMI, IF and/or stored data, via a cable connection system to a plurality of sets of processing apparatus at a location such as a domestic or commercial premises. The method and apparatus allow the distribution of the HDMI data to be achieved in a robust and reliable manner via a plurality of diplexer apparatus.

Abstract: Apparatus and a system is provided to allow the distribution of received data to a number of data processing apparatus and to make selected portions of the data available to each of the data processing apparatus in response to a user selection. The network includes the use of first and further data processing components which can be provided as integrated circuits and which therefore do not require the use of conventional electromechanical switching apparatus.

Abstract: An apparatus has an antenna configured to receive transmitted digital data, wherein the data comprises circular polarity (CP) and linear polarity (LP) format signals. The apparatus also has a waveguide coupled to the antenna and configured to propagate: 1) a first component of the CP format signal which is received; 2) a second component of the CP format signal which is received, said second component being substantially orthogonal to said first component; and 3) the LP format signal which is received. The apparatus further has one or more phase adjusters configured to allow adjustment to be made to match a phase of the first and second components of the CP format signal. The apparatus also has one or more amplitude adjusters configured to allow adjustments to be made to match an amplitude of the first and second components of the CP format signal.

Abstract: A waveguide for use in apparatus for receiving transmitted data signals is provided. The waveguide includes first, second and third channels with the received data entering the first channel and components of the received data, signals being selectively deflected from the first channel into the second or third channels. The form of the components depends on whether the data signals have circular or linear polarity. The components leave the waveguide in substantially the same phase as which they entered the waveguide thereby allowing the same to be subsequently processed. The provision of the waveguide allows the receiving apparatus to be used to receive data signals with either circular and/or linear polarity and be subsequently processed.

Abstract: The invention relates to the provision of apparatus and a method which allows the reception of broadcast data in both linear and circular polarity data formats and allow data from both formats to be available for selection and usage to generate a user selected channel. The apparatus includes an LNB with a waveguide and processing circuitry to allow the processing of the received data and includes adjustment means to allow adjustment of the phase and/or amplitude of typically the orthogonal components of the received CP format data signal to be achieved in a reliable and efficient manner and thereby allow the provision of receiving apparatus with both LP and CP data available for selection and use.

Abstract: The invention relates to apparatus and method which can be used to receive broadcast digital data. The apparatus and method are provided at one or more receiving locations and is connected to one or more broadcast data receivers at each location. The apparatus is capable of receiving and processing data in linear and/or circular polarity formats and the operating condition of the same can be altered in response to a command signal broadcast to the receiving locations prior to the transmission of data in a new format such as to the change in the operating condition of the apparatus to receive and process linear as well as the previously broadcast circular polarity format data.

Abstract: The invention relates to apparatus for receiving digital data signals which are transmitted via a satellite transmission system over a given frequency range. The apparatus includes a receiving horn with a throat and a waveguide. The diameter of the throat is greater than that which would be conventionally chosen, and typically greater than the exit aperture of the waveguide, which allows phase and amplitude to be matched and tracking of the (V) and (H) components of received signals across a given frequency range.
