Abstract:
1. A method for co-relating transport packets on different channels having different PIDs for compatibility with a new system and a legacy system, the method comprising: replicating a first primary packet to create a second primary packet for a particular channel; assigning a unique identifier to said first primary packet and a different unique identifier to said second primary packet; replicating said first primary packet to create a first secondary packet and said second primary packet to create a second secondary packet; and in response to the receipt of a new stream with replicated packets, selecting one of said first and said second primary packets and one of said first and said second secondary packets for said particular channel based on said assigned unique identifier in order to co-relate said selected one of said first and said second primary packets and said selected one of said first and said second secondary packets to one of the legacy system and the new system respectively.
