1. A method for protecting a received data stream comprising the steps of:
- providing an active receiver and a standby receiver, each of said receivers adaptable to receive a data stream;
providing a plurality of data processing units (DPUs), said plural DPUs operatively in communication with said active receiver and said standby receiver;
measuring the quality of said received data stream by said receivers;
providing a signal to said plural DPUs as a function of a quality measurement of said received data stream;
processing said signal at ones of said plural DPUs; and
providing a switching signal from at least one of said plural DPUs to switch the state of said active receiver to standby and the state of said standby receiver to active in response to said switching signal.

Abstract
A system and method for protecting a received data stream. Active receivers and standby receivers are provided, each adaptable to receive a data stream on a traffic channel. Plural data processing units are operatively in communication with the receivers. At least one of the plural DPUs provides a switching signal to the receivers to switch the state of the active receiver to standby and the state of the standby receiver to active as a function of a quality measurement of the received data stream via the traffic channel.
