This paper describes a method of analyzing encapsulated binary data streams for the purposes of performing detailed message analysis. This method evolved from a general purpose analysis tool used to analyze radar data. It is now being applied to the analysis of MPEG-2 content and access control data delivered both in-band and out-of-band. It is particularly useful for compartmentalizing the details of sensitive control and encryption information within the MPEG data strea of an access control system..
The method allows users to describe encapsulated framed data, parsing a binary data stream, and generating human readable output that can be used to analyze and resolve problems. The template files can be tailored and customized to reveal varying levels of proprietary and confidential data within the binary stream.
