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.
