发明名称 SYSTEM AND METHOD FOR DYNAMICALLY ALLOCATING STREAM IDENTIFIERS IN A MULTI-ENCRYPTION TRANSPORT SYSTEM
摘要 The present invention is suitable for use in a multi-encrypted system that dynamically allocates stream identifiers in a secondary overlay stream depending upon the identifiers in a primary encrypted stream. The primary encrypted input stream is monitored to determine the presence of all identifier values. Once the identifier values are determined, the values are stored in an allocation table and marked as ‘in-use’ to ensure that these identifier values are not allocated to any of the secondary overlay streams. The primary encrypted stream is monitored and the allocation table is updated continuously to detect any changes or conflicts to the identifier values, and the secondary overlay streams are dynamically updated accordingly.
