Operating Basics

Deferred -Time Analysis

This section describes the features and identifies the components of the MPEG-2 DVB/ATSC/ISDB-S/ARIB System Analyzer. This section also contains a tutorial to introduce you to the operation and capabilities of the analyzer. The files required for this exercise are included with the application. When you complete the tutorial, you are encouraged to analyze your own input streams and experiment with the configurations and options.

If you need additional information on any topic while reading this section, refer to the Reference section beginning on page 3--1.

The MPEG-2 DVB/ATSC/ISDB-S/ARIB System Analyzer uses several graphical views to present transport stream data. These views give access to each field, and each bit if you wish, within the transport packets, PES packets, and the various PSI, SI, and PSIP tables.

Hierarchic View. The Hierarchic View is a diagram of the data components carried by the transport stream. This view graphically depicts the MPEG transport stream file by using icons to show the interrelationship of its components. These icons identify each PAT (Program Association Table), NIT (Network Information Table), PMT (Program Map Table), and PES (Packetized Elementary Stream) packet, and three types of elementary stream (video, audio, and data). Additional icons indicate the PID (Packet Identification) number for each data component.

For additional information on this view, refer to The Hierarchic View, beginning on page 3--15.

Operating Basics

Interpreted View. The interpreted view shows every field in the selected transport packet, table section, or PES (packetized elementary stream) packet. Any packet in the file can be accessed. You can search for errors in this view.

The interpreted view shown below is of one 188-byte transport packet in the SAMPLE.TRP binary stream; this view can be created by double-clicking on the TS (engine and tender) icon in the Hierarchic view.

For additional information on this view, refer to The Interpreted View, beginning on page 3--23.

Timing Displays. Two types of timing displays are available: PCR (Program Clock Reference) contained in the transport packet headers and PTS/DTS (Presentation/Display Time Stamp) contained in PES packet headers. The PCRs are shown in a graphical format indicating their arrival time. The graphical display of the PTS/DTS shows a time line for each access unit (such as a video frame) indicating data arrival and value of each time stamp.

Acquiring Transport Stream and Elementary Stream Files

The standard configuration Tektronix MTS200 MPEG Test System includes sample video and audio elementary stream files and a sample transport stream file in the Cfg-trp directory. These files contain pictures, common industry test signals, and sample signals in MPEG-2 format. Use these files as example formats for the tutorials and to construct sample transport streams.

Two additional sources of elementary stream files are available: a CD ROM (Tektronix part number 063-1914-XX) and the Tektronix FTP site.

Operating Basics

Test System CD ROM

To use the files on the CD ROM, either copy the files to the C:\MTS200 directory on the system disk or leave the disk in the CD ROM drive.

Audio Files. The CD ROM contains the following audio files in the Audio directory:

15kz--064.mp2 15kz--128.mp2 15kz--192.mp2 15kz--256.mp2 1kz--064.mp2 1kz--128.mp2 1kz--192.mp2 1kz--256.mp2 400--064.mp2 400--128.mp2 400--192.mp2 400--256.mp2

The file names indicate the elementary stream bit rate. For example, the file 15kz--256.mp2 contains a 15 kHz audio tone at 0.256 Mbits/s.

The following Dolby digital audio files are also available:

4kz--064.mp2 4kz--128.mp2 4kz--192.mp2 4kz--256.mp2 Music064.mp2 Music128.mp2 Music192.mp2 Music256.mp2 Sync--064.mp2 Sync--128.mp2 Sync--192.mp2 Sync--256.mp2
