摘要：
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.
摘要（中）：
本发明涉及可用于接收广播数字数据的装置和方法。 该装置和方法设置在一个或多个接收位置处，并且连接到每个位置处的一个或多个广播数据接收器。 该装置能够以线性和/或圆形极性格式接收和处理数据，并且可以响应于在以新格式传输数据之前向接收位置广播的命令信号来改变其操作条件，例如 对于接收和处理线性的装置的操作条件的改变以及先前广播的圆极性格式数据。
