DiVi Analyzer

The DiVi Analyzer is a useful, fast and easy-to-use analyzing tool for DVB service information (DVB-SI). With a single mouse-click, it extracts the SI data from a DVB transport streams (DVB-TS) and converts it into a readable, well-structured XML file. Now, developers and testers of DVB receiver hardware/software can check SI data faster and find inconsistencies easier.

DiVi Analyzer supports many different SI data tables and especially enables the automatic decoding of the Huffman-encrypted SI data in BBC's Freeview HD (DVB-T2) broadcast. DiVi Analyzer is also part of the DiVi Software Tools, a package of encoders and decoders, which besides the SI data analysis also enables the generation of own DVB transport stream files.

Use Cases

  • Analysis of DVB service information, e.g. channel names, program information or more in case of errors or inconsistencies in DVB receiver tests, e.g. Set-Top Box, TV set or similar.
  • Comparison of DVB receiver output, e.g. EPG or channel list, with original SI data content.
  • Detection of possible non-standard conform SI data in live DVB transmissions, which can cause DVB receiver errors.
  • Editing and categorization of own DVB test stream collections with additional XML files.
  • Use of standard XML enables further processing with various common tools.
  • FREEVIEW HDPart of test environment for DTT receiver and recorder products, which intend to be approved by DTV Services and receive the FREEVIEW / FREEVIEW HD certification. (The FREEVIEW logo is a trade mark of DTV Services Ltd.)

Features

  • Extraction of service information (SI) data from DVB transport streams.
  • Conversion of SI data into single or multiple human-readable XML files.
  • Support of PAT, PMT, SDT, BAT, TOT, TDT, EIT, NIT, CAT
  • FREEVIEW HD support: Analyzing of SI data, encrypted with BBC's Huffman tables in DVB-T2.
  • New D-Book 6.1 support: Support of all relevant descriptors and tables defined in D-Book 6.1.
  • Automatic integration into Windows context menu: Start conversion with a single mouse click.
  • Many configurable parameters
  • Also suited for batch job processing

XML to TS Conversion
With a single mouse click, DiVi Analyzer extracts SI data from a DVB transport
stream and converts it into XML format.

 

Example of converted XML file
The human-readable, well-structured XML file helps to analyse SI data values
and can also be used for further automated processing in sophisticated
test scenarios. See complete example XML file.

DiVi Analyzer vs. DiVi Software Tools

The DiVi Analyzer is also part of the DiVi Software Tools, a collection of several converters, generators, a TS multiplexer and de-multiplexer. The DiVi Software Tools are used to extract SI data out of existing TS files as well as to generate new ready-to-broadcast TS files out of own customer specific SI data tables, e.g. in XML formats. If you are not only looking for an SI analysis, but also for generation of own TS files, you should take a look at the DiVi Software Tools.
