IIsdbCAContractInformationDescriptor::GetContractVerificationInfo method (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.]
Gets data from the contract_verification_info field in an Integrated Services Digital Broadcasting (ISDB) conditional access (CA) contract information descriptor. This field is used to determine allowable uses of the conditional access service.
Syntax
HRESULT GetContractVerificationInfo(
[in] BYTE bBufLength,
[out] BYTE *pbBuf
);
Parameters
[in] bBufLength
Specifies the length of the buffer that holds the contract verification data.
[out] pbBuf
Pointer to a buffer that receives the contract verification data.
Return value
If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
Remarks
The contract_verification_info field is used to confirm whether the service, or the ES group that comprises a service, can be reserved for viewing (recording). When the contract_verification_info field appears in the event information table (EIT), it is also used to determine whether the event in question is a flat-type or tier-type event, an ES group that comprises an event, a pay-per-view (PPV) event, or an ES group that comprises a PPV event. If the event is a PPV event or ES group that comprises a PPV event, the descriptor is used to determine the viewing fee and recording request information.
