IGuideData interface (bdatif.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.]
The IGuideData interface is exposed by the BDA MPEG-2 Transport Information Filter (TIF). It enables the client to get service information from the MPEG-2 transport stream. Use this interface if you are writing a guide store loader.
Inheritance
The IGuideData interface inherits from the IUnknown interface. IGuideData also has these types of members:
Methods
The IGuideData interface has these methods.
| IGuideData::GetGuideProgramIDs The GetGuideProgramIDs method returns a list of unique identifiers for all of the programs contained in all transport streams. |
| IGuideData::GetProgramProperties The GetProgramProperties method retrieves the properties for a specified program. |
| IGuideData::GetScheduleEntryIDs The GetScheduleEntryIDs method returns a list of unique identifiers for all of the schedule entries contained in all transport streams. |
| IGuideData::GetScheduleEntryProperties The GetScheduleEntryProperties method retrieves the properties for a specified schedule entry. |
| IGuideData::GetServiceProperties The GetServiceProperties method retrieves the properties for a specified service. |
| IGuideData::GetServices The GetServices method retrieves a collection of tune requests representing all the services available in the tuning space. |
Remarks
The TIF collects service information for services, programs, and schedule entries. A service is analogous to a channel; a program is a television show (also known as an "event"); and a schedule entry is an event that occurs at a specific time on a specific service.
For each program and schedule entry, the TIF creates a string that uniquely identifies that element within the multiplex. The GetGuideProgramIDs and GetScheduleEntryIDs methods return a list of these identifiers. You can then pass the identifier to the GetProgramProperties and GetScheduleEntryProperties methods to get additional properties for a particular element.
To declare the interface identifier (IID) for this interface, use the __uuidof operator: __uuidof(IGuideData).
