Abstract
A content access device includes an interface module that receives a transport stream and outputs a processed transport stream. An input buffer buffers the received transport stream. A polling processor processes the transport stream based on the at least one key to generate the processed transport stream, wherein the polling processor operates to descramble individual packets of the transport stream in a plurality of polling slots of a polling loop. An output buffer buffers the processed transport stream for output by the interface module.
