Technical background

TSCA - 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 intermediary between TSCA clients and MPEG cores. The tsca.exe, MpegCore.exe, and CoreManag and HTTP (Hypertext Transfer Protocol) to 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:

C:\program files (x86)\tektronix\mpeg\mtsa\apps\tsca\xml\

The default port range is 15700-15800. You can change these values if they conﬂict with other applications. You must have local administrator rightstobe able to use IP analysis. If you need to change your rights, please consult your system administrator.

er.exe processes use SNMP (Simple Network Management Protocol)

Program view

The TSCA software displays two primary views selected using tabs: FlexVu® Plus and Analysis.

Using the FlexVu® Plus window, you can assemble up to four views that you select from the Analysis window. This allows you to customize the view by selecting

views that are most relevant to the analysis task. The FlexVu® Plus window is

the describedindetailintheMTSA-HW and MTSA-PC Quick Start User Manual.

e Analysis window uses a single main program summary window with different

Th context sensitive views contained within tabbed frames. This provides the maximum amount of useful information, while keeping the screen from appearing cluttered. From the main window, you can access the following views: Program, Tests, Tables, PID, Packets, and Interface.

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.

Tests view

SI/PSI (Tables) view

Errors that are up to the highest level. This allows you to monitor all of the programs in the stream at a high level and then quickly go to lower levels as necessary to locate a problem.

The Tests view enables you to isolate errors to the speciﬁc tests that have been applied to the transport stream. The error log is automatically ﬁltered by the selected test, and can also be ﬁltered by Packet Identiﬁer (PID).

In addition to the standard ﬁrst, second, and third priority tests includedin TR 101 290 standard, tests are available for Program Clock Reference (PCR) jitter and program/PID bit rate.

A variability test enables you to test the changes in the bit rate of a speciﬁcPID, and there are many tests that are speciﬁc to ISDB-T and ISDB-S streams.

The SI/PSI (Tables) view displays the service information tables that have occurred in the analyzed stream that comply with the selected digital video standard. This includes MPEG-speciﬁc program information, DVB service information, and ATSC, ISDB program, and system protocol information.

The tables are grouped together by function and hyperlinks enable you to quickly access related information within other tables.

The Packets view displays information about all of the packets found in the transport stream grouped according to content. These groups include PID value, SFN mega-initialization packets (MIPs) (DVB only), and ISDB-T and ISDB-TB information packets (IIPs).

When you select a speciﬁc PID or MIP, only packets carrying that particular PID or MIP are displayed. A section view is also available. Deferred analysis of PCAP ﬁles allows you to see the Ethernet packets. The Packets view is not available in real time mode. However, you can examine packets in a real time stream by using the CaptureVu feature.

The CaptureVu feature captures a snapshot of system events in real and deferred time, and allows you to debug the intermittent and complex problems that traditional analyzers miss.

You can initiate CaptureVu either manually or automatically by associating a CaptureVu Breakpoint with any test event.

When a breakpoint is detected, either manual or automatic, the stream is paused and an in-depth deferred time analysis can be performed on stored data. This

Similarly, when an LED representing a parent node in a tree is disabled or enabled, all subsidiary (or child) nodes are also disabled or enabled to reﬂect the state of the parent node. When an LED representing a parent node is reset, all the child nodes are also reset.

The lower view p

The test tabs that are available will depend on the interpretation standard that you choose. For example, with the DVB interpretation standard, the available tabs are TR 101 209 and Other. Other interpretation standards will generate different tabs and different sets of tests. (See page 146, TSCA – SI/PSI nodes.)

When any test in the transport stream has failed (and has not been reset), youcan identify which individual tests have failed by observing the red LEDs.

You can use the shortcut menus to reset and disable tests, to set alarms, CaptureVu Breakpoints and record ﬂags, and to jump to associated tests.

The Event Log screen displays the log entries as shown in the following ﬁgure for the whole transport stream. In deferred mode, the packet generating the error report can be inspected by highlighting the error and selecting Go to packet from the shortcut menu. Similarly, in real time analysis mode, and where an event concerns a PID carrying a PCR, you can use the shortcut menu to jump to the relevant PCR graph. Deferred PCAP ﬁle analysis enables a shortcut that allows Ethernet packets to be viewed.

In the navigation view, PIDs are grouped under the following subordinate nodes:

Reserved PIDs

Referenced P

Unreferenced PIDs

SI/PSI PIDs

User PIDs

Obsolete PIDs (deferred analysis only)

The number of PIDs in each group is shown adjacent to the node. The root node label shows the total number of PIDs found and the Network Name.

When highlighted, the All PIDs node displays in the detail pane all of the PIDs that are found in the analyzed stream.

Each of these subordinate nodes contains PIDs belonging to that group. PIDsare allocated during analysis, and the number of PIDs is identiﬁed for each node. You can also allocate PID numbers to the User PID node, although User PIDs may not necessarily have been found in the stream. This feature allows you to compare the properties of one or more PIDs more easily.

Each PID is associated with a number of tests. If one or more tests fail, they will be listed under the relevant PID node in the navigation view. Selecting the PID node will display a summary, in the detail view, of all associated tests thathave been found. Selecting a speciﬁc test in the Associated Tests pane will display the

The Graphs tab contains instantaneous graphs and trend graphs.

The instantaneous graphs display instantaneous measurements in graphical form. The trend graphs display trends in measurements in graphical form.

The inter

The right panel contains Readings and Controls. The Readings area displays values received from the card itself.

The RF Lock LED conveys different types of information. If full lock onto the channel is acquired and it is receiving the signal correctly, the LED will light up green. When a signal is present but no lock is achieved, the indicator is red.When no signal is found, the indicator is gray.

In the Readings area, the LED colors are as follows:

Green On

The trend graphs extend the principle of the instantaneous graphs by graphing measurements over longer periods.
