CA Hierarchical Analysis
With a user-defined CA definition file, the Analyzer extracts
CA data from the transport stream and displays it in a hier-
archical tree structure with easy-to-interpret, formatted
views. With the Analyzer, users can verify that the transport
stream contains the correct CA data for each program.
PSI/SI/PSIP Table and Descriptor Decode Analysis
Accurate and complete PSI/SI/PSIP table and descriptor data
is imperative for proper creation of the electronic program
guide (EPG). Using the Analyzer’s fully decoded table and
descriptor displays, developers can verify proper creation
and interpretation of these tables, while broadcasters can
monitor their contents.
Private Data Analysis
With user-defined private definition files, the Analyzer
successfully parses private tables and descriptors, allowing
users to validate proprietary data that would otherwise
remain hidden in the transport stream. Together with
PSI/SI/PSIP table and descriptor decoding performed by
the Analyzer, private data decoding allows users to verify
the creation and content of the EPG.
Packet-by-Packet Analysis
The Packet Editor application, provided with the Analyzer
and Generator application modules, allows users to analyze
data on a packet-by-packet basis and provides access to each
bit in the transport packet header and payload. The Packet
Editor also allows users to exercise the equipment under test
by modifying parameters, corrupting packets, or including
null packets at strategic locations in the multiplex.
