Export to folder after SI scan in DVBStreamExplorer

If you are using DVBStreamExplorer to scan entire DVB, ATSC or ISDB networks for PSI/SI/PSIP information, you might appreciate a new feature in DVBStreamExplorer Professional Edition V3.0.113 that allows you to have various files exported and saved automatically when PSI/SI/PSIP scan is completed. Note that this feature is only applicable for 'Multiple * MUX scanning' features found in PSI/SI/PSIP menu.

The new feature can be enabled from Options / Preferences / SI scan page as shown below.


Here you can enable/disable the feature, select destination folder and select which file types you want to export.
'Save SI XML' corresponds to File / Save/Save As file, which is a file type that can be loaded by DVBStreamExplorer for offline viewing of PSI/SI/PSIP information.
'Save service XML' and 'Save CSV' corresponds to options found in File / Export / XML and File / Export / CSV.
All files will be saved in specified folder. File name will be automatically generated based on network type, export type and date/time of export. The date/time part of file name is based on, but does not necessarily strictly conform to, ISO 8601. The time is specified in UTC to allow files to be easily exchanged between different time zones.



BDA tuner configuration in DVBStreamExplorer

DVBStreamExplorer V3.0.113 fixes a problem that it would fail to initialize some BDA devices on Windows 7. The old device selection box looked like below.


 In case of device initialization failure you would see a message like below when starting application.



While fixing this issue, it was found that the application was not always able to reliably detect BDA tuner configuration. I.e. it was possible that a DVB-T device could be detected as DVB-S device.

You can verify how your BDA tuner device was detected by application by opening Device / Settings page.
Below is a screenshot showing how a DVB-C  device was detected as DVB-S.


As a workaround a new feature has been added, so that it is now possible to specify network (tuner) type when selecting device during application launch.
The new device selection box is shown below.


You can select between auto detect, DVB-S, DVB-T, DVB-C and ATSC.
It is recommended to first try with auto detect. If then network type is not detected correctly by application, you will need to specify correct network type when launching application.
Note that application can only remember the last network type used. So if you change between different BDA device types, you will have to specify correct network type every time you launch application unless you are using auto detect option.
