IIsdbComponentGroupDescriptor interface (dvbsiparser.h)
[The feature associated with this page, Microsoft TV Technologies, is a legacy feature. Microsoft strongly recommends that new code does not use this feature.]
Implements methods that get data from an Integrated Services Digital Broadcasting (ISDB) component group descriptor. The component group descriptor appears in the ISDB service information as part of the event information table (EIT) and describes component grouping in an event.
Inheritance
The IIsdbComponentGroupDescriptor interface inherits from the IUnknown interface. IIsdbComponentGroupDescriptor also has these types of members:
Methods
The IIsdbComponentGroupDescriptor interface has these methods.
| IIsdbComponentGroupDescriptor::GetComponentGroupType Gets the value of the component_group_type field from an Integrated Services Digital Broadcasting (ISDB) component group descriptor. This three-bit field indicates the group type to which the components in the descriptor belong. |
| IIsdbComponentGroupDescriptor::GetCountOfRecords Gets the number of component records in an Integrated Services Digital Broadcasting (ISDB) component group descriptor. |
| IIsdbComponentGroupDescriptor::GetLength Gets the body length of an Integrated Services Digital Broadcasting (ISDB) component group descriptor, in bytes. |
| IIsdbComponentGroupDescriptor::GetRecordCAUnitCAUnitId Gets a conditional access unit identifier from a specified component group record in an Integrated Services Digital Broadcasting (ISDB) component group descriptor. |
| IIsdbComponentGroupDescriptor::GetRecordCAUnitComponentTag Gets the tag that identifies a component record in an Integrated Services Digital Broadcasting (ISDB) component group descriptor. |
| IIsdbComponentGroupDescriptor::GetRecordCAUnitNumberOfComponents Gets the number of components corresponding to a conditional access unit from an Integrated Services Digital Broadcasting (ISDB) component group descriptor. |
| IIsdbComponentGroupDescriptor::GetRecordGroupId Gets the component group identifier from an Integrated Services Digital Broadcasting (ISDB) component group descriptor. |
| IIsdbComponentGroupDescriptor::GetRecordNumberOfCAUnit Gets the number of conditional access unit records in a component group from an Integrated Services Digital Broadcasting (ISDB) component group descriptor. |
| IIsdbComponentGroupDescriptor::GetRecordTextW Gets the text that describes a component group from an Integrated Services Digital Broadcasting (ISDB) component group descriptor. |
| IIsdbComponentGroupDescriptor::GetRecordTotalBitRate Gets the total bit rate from a component within a component group in an Integrated Services Digital Broadcasting (ISDB) component group descriptor. |
| IIsdbComponentGroupDescriptor::GetTag Gets the tag that identifies an Integrated Services Digital Broadcasting (ISDB) component group descriptor. |
