Abstract:
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.
