Technical Background
Transport Stream Compliance Analyzer - Getting Started
The analyzer has a client-server architecture. Every time the analyzer opens, it
starts two processes: tsca.exe, which is the client, and MpegCore.exe, which is the
MPEG analysis engine. Additionally, when the analyzer opens for the first time,
another single process, CoreManager.exe, is started. CoreManager.exe forms an

The Program view provides a fast overview of the transport stream contents
in terms of program content, bit rate use by each program, and TR 101 290
test results. Red, amber, and green LEDs highlight errors associated with each
program, or element of a program, within the transport stream. Red LEDs indicate
that there are current errors in the stream, amber LEDs indicate that errors have
occurred but are now clear, and green LEDs indicate that no errors have been
detected.
