Digital Media Receiver Monitoring System

摘要

The invention provides a method for monitoring a digital media receiver (including receivers for television or other type of digital media) to determine whether it is necessary for a receiver to re-connect in order to continue receiving a predetermined channel or stream. This invention is useful in digital media monitoring systems and in situations with many receivers connected to the same signal source and predetermined channels defined to be output by each receiver. One embodiment of the invention uses an auditing receiver that constantly scans the upstream channel-map, guide data, service information or system information to determine if the connection parameters required for receiving each predetermined stream have changed. Some examples of connection parameters include packet identifiers (PIDs), radio frequency (RF) channel and uniform resource locator (URL), depending on the type of broadcast and stream. When the auditing receiver gathers the latest connection parameters, a monitoring system compares the recently checked connection parameters to the connection parameters currently in use on each other receiver to determine if each receiver needs to be re-connected to continue receiving the predetermined stream defined for that receiver.

主权项

1. A method for monitoring one or more active receivers, the method comprising:
providing one or more active receivers with connection parameters each for receiving a digital media input and providing a predetermined configured stream; providing a monitoring server for communicating with the one or more active receivers; providing an auditing receiver for querying from a connection parameter data source a current required connection parameters for each of the one or more active receivers; wherein the monitoring server repeatedly communicates with the auditing receiver to query the current required connection parameters for each of the one or more active receivers and compares the current required connection parameters to the connection parameters for each of a corresponding one or more active receivers for determining if re-connection of any of the one or more active receivers is necessary to continue providing the configured stream, wherein connection parameters and current required connection parameters include information required to select a predetermined configured stream from the digital media input; and sending a command to re-connect from the monitoring server to the corresponding one of the one or more active receivers if the current required connection parameters do not match the connection parameters.
