DTVKit Wiki

These notes apply between releases 1.0.0 and 1.1.0 of DVBCore:-

• New functionality:
  • Support for receiver and broadcast mix audio description (AD) has been added.
  • Raw SI data is now held for all EIT descriptors to reduce memory usage and allow other modules and/or applications to extract data from descriptors that DVBCore doesn't understand. The size of an event returned to an application is also a lot smaller, so the size of the array returned to an application when it requests the full schedule for a service is also smaller.
  • H.265 UHD video support.
  • http://bugs.dtvkit.org/view.php?id=37 Add ability to create a binary release.
  • http://bugs.dtvkit.org/view.php?id=60 Add MHEG externals for South Africa resident programmes.
  • http://bugs.dtvkit.org/view.php?id=78 ISO language code definitions are now public.
  • http://bugs.dtvkit.org/view.php?id=79 Enable 32-bit build on 64-bit host systems.
  • http://bugs.dtvkit.org/view.php?id=141 Parse carousel ID descriptor in the PMT.
  • http://bugs.dtvkit.org/view.php?id=166 Provide more ways for MHEG to control video.

• DVB API changes:
  • The event passed to ADB_GetEventGuidance can be NULL to just get the guidance text defined by the service.
  • The UTF-8 string returned by the following functions should now be freed using STB_ReleaseUnicodeString:
    • ADB_GetEventName
    • ADB_GetEventDescription
    • ADB_GetEventExtendedDescription
  • The following functions now return an array of U16BIT values rather than U32BIT:
    • ADB_GetServiceListLcns
    • ADB_GetServiceListOrigLcns
  • The function ADB_GetRequiredADPid takes an extra argument which indicates whether the returned PID represents a broadcast mix AD stream:
    • U16BIT ADB_GetRequiredADPid(void *s_ptr, BOOLEAN *broadcast_mix)
  • A new API has been added to determine if an event contains an extended event description:
    • BOOLEAN ADB_GetEventHasExtendedDescription(void *event_ptr)
  • A new API has been added to return the list of components for an event, with a new ADB_EVENT_COMPONENT_INFO structure:
    • U8BIT ADB_GetEventComponentList(void *event_ptr, ADB_EVENT_COMPONENT_INFO **component_list)
  • A new Freesat specific API has been added:
    • U16BIT ADB_GetFreesatServiceId(void *s_ptr)
  • http://bugs.dtvkit.org/view.php?id=156 Rename ACTL_SetMhegVolumeAdjustment() to make it non-MHEG-specific.

• Platform API changes:
  • A new network API has been added to return the currently selected interface type:
    • E_NW_INTERFACE STB_NWGetSelectedInterface(void)
  • A new demux function has been added that is required if MHEG ICS is implemented:
    • void STB_DMXWriteDemux(U8BIT path, U8BIT *data, U32BIT size)

• HbbTV changes:
  • Implementation of HbbTV functions HBBTV_ObtainServiceList and HBBTV_ReleaseServiceList have been removed to allow a product specific implementation.

• Bug fixes:
  • http://bugs.dtvkit.org/view.php?id=34 DVBCore doesn't compile if “export DTVKIT_COUNTRY_FINLAND = 1”
  • http://bugs.dtvkit.org/view.php?id=53 Fixed possible buffer overrun when decoding subtitles.
  • http://bugs.dtvkit.org/view.php?id=61 Uninitialised conflicting timer handles returned by ATMR_GetNumSimultaneousRecordings.
  • http://bugs.dtvkit.org/view.php?id=62 Memory leak in EXT_HbbtvGetEvent.
  • http://bugs.dtvkit.org/view.php?id=64 There's a memory leak when freeing a Freesat BAT table.
  • http://bugs.dtvkit.org/view.php?id=89 Wrong function used to get the number of recommendation CRIDs for HbbTV.
  • http://bugs.dtvkit.org/view.php?id=95 Crash with an arithmetic exception (divide by zero?).
  • http://bugs.dtvkit.org/view.php?id=97 In the HBBTV external interface, event strings are not freed.
  • http://bugs.dtvkit.org/view.php?id=99 ADB_GetEventContentData should initialise length to 0, when returning NULL.
  • http://bugs.dtvkit.org/view.php?id=100 Cleanup externals/MHEG/src/service.c - free events and check make copy of content data.
  • http://bugs.dtvkit.org/view.php?id=107 Change string handling in externals/MHEG/src/service.c & other cleanups in externals/MHEG/src/service.c.
  • http://bugs.dtvkit.org/view.php?id=108 DVBCore shouldn't call MHEG directly.
  • http://bugs.dtvkit.org/view.php?id=119 Service required by MHEG isn't always found.

  • http://bugs.dtvkit.org/view.php?id=133 Size of data_types isn't stored in Freesat linkage descriptor.
  • http://bugs.dtvkit.org/view.php?id=137 Freesat tunnelled data descriptor can be signalled on streams of type 0x0B.
  • http://bugs.dtvkit.org/view.php?id=160 Data outside the Freesat linkage descriptor is being read.
