CIRCULAR AND/OF LINEAR POLARITY FORMAT DATA RECEIVING APPARATUS

摘要

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.
