Abstract
Official abstract text for this publication.
The present invention is suitable for use in a multi-encrypted system that dynamically allocates stream identifiers in a second stream depending upon the identifiers in a first stream. The first stream is monitored and counters are incremented with the presence of an identifier. The count for each of the counters is then received. Using the count, a control processor then assigns or revises identifiers in the second stream.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for dynamically allocating identifier values by a headend device to a second encrypted stream depending upon a first encrypted stream, the method comprising: determining a plurality of identifier values of the first encrypted stream, wherein the first encrypted stream comprises first encrypted packets; receiving a clear stream at a packet selector; determining critical packets of the clear stream, wherein determining the critical packets compris…
