Claim Text:
1. A content access device comprising: an interface module that receives a transport stream and outputs a processed transport stream; an input buffer, coupled to the interface module, for buffering the received transport stream; a polling processor, coupled to the input buffer, that processes the transport stream to generate the processed transport stream, wherein the polling processor operates via polling to descramble individual packets of the transport stream in a plurality of polling slots of a polling loop, wherein the polling slots facilitate a predetermined set of packet processing tasks by the polling processor on the individual packets of the transport stream including descrambling of the individual packets of the transport stream, wherein the polling processor initiates each of the plurality of polling slots by polling the input buffer for a corresponding one of the individual packets of the transport stream, descrambles the corresponding one of the individual packets retrieved from the input buffer, and wherein the plurality of polling slots have a polling slot duration selected to complete the predetermined set of packet processing tasks by the polling processor on the corresponding one of the individual packets of the transport stream; and an output buffer, coupled to the polling processor and the interface module, for buffering the processed transport stream for output by the interface module.
