1. A method for processing media packets, comprising:

  • receiving a stream of media packets at a packet processor having a single CPU;

    dividing processing operations for processing a received media packet into two or more frames of protected processing operations, wherein an elapsed time for processing the two or more frames of protected processing operations is less than a time interval between the receipt of media packets in the stream and respective frames of protected processing operations are temporally separated;

    in the time interval between the receipt of media packets in the stream, alternating between (i) performing at the CPU the respective frames of protected processing operations in a protected processing environment that is not affected by other processing operations, and (ii) freeing up the CPU to selectively perform other processing operations in a non-protected processing environment during the temporal separation between the frames of protected processing operations.
