Patent ID: 8381251

Claim:
A method of test receiving alternative reception frequencies in a receiver receiving a continuous flow of information of a unidirectional digital broadcasting transmission at a first reception frequency, the continuous flow of information including specific user terminating information transmitted in clusters, the receiver including an information transfer routine that extracts a flow of specific user terminating information from the received continuous flow of information, the method comprising: predicting an interruption in the form of a natural break in the transmitted flow of specific user terminating information, based on an indication of the end of a cluster of the specific user terminating information, where the indication of the end of the cluster of specific user terminating information is part of the specific user terminating information; evaluating the interruption to determine whether it will be of an adequate length of time, and generating a positive response if it is evaluated that the interruption will be of an adequate length of time; changing the reception frequency of the receiver from the first reception frequency to an alternative reception frequency if the evaluation has generated a positive response; test receiving the alternative reception frequency; enabling reception and extraction of the flow of specific user terminating information.
