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 intermedia

The tsca.exe, MpegCore.exe, and CoreManager.exe processes use SNMP (Simple Network Ma communicate. The port numbers used for communication are read from a conﬁguration ﬁle, CoreInfo.xml. In a default installation, the path to the ﬁle is

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.

The error log is automatically ﬁlteredbythe selected test, and can also be ﬁlteredbyPacketIdentiﬁer (PID).

If necessary, select a ﬁle type from the Files of type drop-down list. Currently, two types are available: MPEG Transport Stream ﬁles and PCAP ﬁles.

MPEG transport stream ﬁles contain interlinked tables and coded

identiﬁers, which separate the programs and the elementary streams within the programs.

PCAP ﬁles contain raw packets of network data. A PCAP may contain

NOTE. If either the ’Use Arrival Timestamps’ or the ’Use TTS Timestamps’ check

box is selected, timestamps, which may have been added when the stream was generated, will be used, in the analysis of the stream.

Program Navigation - Program Nodes

Each of the program nodes in the transport stream represents a single program referenced within the stream. When a program node is selected in the navigation view, the detail pane displays the details of the program. The LED adjacent to the program node represents the status of its child nodes (elementary streams) and the related

tests.

Using the Program View

The program detail view provides you with an overview of the selected program, allowing you to see the relative data rates and stream types of all of the PIDs that are associated with the program (including PCR and ECM PIDs). If the program contains an MPEG2 or H.264 video stream, it is decoded to produce a thumbnail picture of the content; this is updated during real time analysis. Similarly, where EPG information is associated with the program, a summary (Now and Next program) is displayed. PID content is indicated using icons. (See page 1-100, Icons.) Bar chart and pie chart views are available.

PID related information is available under the Summary tab.

The Thumbnails tab displays thumbnails and details of the streams for each of the programs (where available). (See page 1-115, Thumbnail Views.)

The Program Tests tab shows tests related to the program. Similarly, the Bit rate Graphs tab displays the program bit rate in graph form.

Many tests have associated parameters; these parameters are set by the selected standard, but you can modify the settings. (See page 1-117, Parameter Edit.)
