    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.

    摘要: An apparatus in a digital network includes the logic for allocating and assigning packet identifiers (PIDs) to digital packets, such as MPEG packets. The logic can reside in a device that transmits a transport stream or a device that controls a transport stream transmitter. In the preferred embodiment, a session number is associated a program and with an output port of a transport stream transmitter; and the session number is unique for that output port. The logic associates a PID from a set of allocated PIDs with the session number. The set of allocated PID values are PMT_PIDs, which are used for identifying the PMT packets, and the set of PMT_PIDs is scalable. In the preferred embodiment, the logic also associates the PMT_PID to the session number using a predetermined scheme. The apparatus also includes logic for assigning a set of PID values to the elementary streams of a program. In the preferred embodiment, number of PIDs assigned to the elementary streams of a program is no more than the number of elementary streams of the program.
