========================== DUNE HD STB -- DVB SUPPORT ========================== DVB-S setup and scan -------------------- Native Dune UI includes DVB-S setup and scan functionality (available via Setup / Applications / DVB-S). The STB persistently stores (in the flash memory) the following kinds of DVB-S configuration data: - "Channel model" data. - This enumerates all satellites and transponders known to the STB, and DVB-S channels/bouquets found as the result of DVB-S scan operation. - It is possible to import the list of satellites and transponders from the popular "satellites.xml" file format: put the XML file named "satellites*.xml" to a USB flash drive, choose the XML file in the Dune's file browser and press ENTER RC button. NOTE: As the result of such an import, the list of DVB-S channels/bouquets is cleared. - Location in the filesystem: /config/dvb_s_channels.xml - Default initial state: - Absent (no satellites defined). - Is written: - When the import of "satellies.xml" file via native Dune UI is performed. - As the result of the succesfull DVB-S scan operation. - Is read/used: - When "Edit LNB configuration" Setup UI is launched (to allow the user to choose the satellite from the list of known satellites). - When DVB-S scan is performed. - When built-in UI (available via TV / DVB-S) for browsing available DVB-S channels is accessed. - "LNB configuration" data. - This describes the DVB-S hardware connected to the STB: what LNBs are available and what satellites are available through these LNBs (and what DiSeqC options should be used for accessing these satellites). - Can be configured directly via native Dune Setup UI. - Location in the filesystem: /config/dvb_s_setup.xml - Default initial state: - Absent (no LNB configurations defined). - Is written: - When the user changes LNB configuration via native Dune Setup UI. - Is read/used: - When DVB-S scan is performed. - Scan results in M3U format. - This contains the list of DVB-S channels found as the result of DVB-S scan. - Each DVB-S channel is represented as a DVB-S media_url (see "DVB-S media_url syntax" section). NOTE: each media_url is valid as long as "LNB configuration" data which was used during DVB-S scan remains unchanged. - Location in the filesystem: /config/dvb_s_channels.m3u - Default initial state: - Absent (no DVB-S channels defined). - Is written: - As the result of the succesfull DVB-S scan operation. - Is read/used: - Is never used by the native Dune UI. Is generated mostly for debugging purposes, and can also be used by 3-party applications.

DVB-C setup and scan -------------------- Native Dune UI includes DVB-C setup and scan functionality (available via Setup / Applications / DVB-C). The STB persistently stores (in the flash memory) the following kinds of DVB-C configuration data: - Scan configuration data. - Defines DVB-C scan parameters. - Can be configured directly via native Dune Setup UI. - It is stored along with other STB settings in "/config/settings.properties" and is not intended to be directly used/modified by 3rd-party software. - Default initial state: - Some typical DVB-C parameters. - Is written: - When the user changes DVB-C configuration via native Dune Setup UI. - Is read/used: - When DVB-C scan is performed. - Scan results. - Contains the list of DVB-C channels found as the result of DVB-C scan. - Each DVB-C channel is represented as a DVB-C media_url (see "DVB-C media_url syntax" section). A folder is created for each scanned channel, named with service name (in escaped form as described in DVB media_url format), containing the "dune_folder.txt" with the media_url in its content. NOTE: This representation is likely to change (become more consistent with the way scan results are stored for DVB-S) in future firmware versions. - Location in the filesystem: "/flashdata/DVBC_channels" - Default initial state: - Absent (no DVB-C channels defined). - Is written: - As the result of the succesfull DVB-C scan operation. - Is read/used: - When built-in UI (available via TV / DVB-C) for browsing available DVB-C channels is accessed.
