ISCTE_EAS interface (atscpsipparser.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 ISCTE_EAS interface enables the client to get data from an ATSC emergency alert message (EAS) table. The IAtscPsipParser::GetEAS method returns a pointer to this interface.
For more information about EAS tables, see ANSI-J-STD-042-A, Emergency Alert Message for Cable.
Inheritance
The ISCTE_EAS interface inherits from the IUnknown interface. ISCTE_EAS also has these types of members:
Methods
The ISCTE_EAS interface has these methods.
| ISCTE_EAS::GetAlertPriority The GetAlertPriority method returns the alert priority. |
| ISCTE_EAS::GetAlertText The GetAlertText method gets the alert text for a specified ISO 639 language code. |
| ISCTE_EAS::GetCountOfTableDescriptors The GetCountOfTableDescriptors method returns the number of descriptors in the EAS table. |
| ISCTE_EAS::GetDetailsAudioOOBSourceID The GetDetailsAudioOOBSourceID method returns the source identifier of the virtual audio channel for the emergency alert. |
| ISCTE_EAS::GetDetailsMajor The GetDetailsMajor method returns the major channel number for the details channel. |
| ISCTE_EAS::GetDetailsMinor The GetDetailsMinor method returns the minor channel number for the details channel. |
| ISCTE_EAS::GetDetailsOOBSourceID The GetDetailsOOBSourceID method returns the source identifier of the virtual details channel for the emergency alert. |
| ISCTE_EAS::GetDuration The GetDuration method returns the expected duration of the alert. |
| ISCTE_EAS::GetEASEventCode The GetEASEventCode method returns the EAS event code. |
| ISCTE_EAS::GetEASEventCodeLen The GetEASEventCodeLen method returns the size of the EAS event code. |
| ISCTE_EAS::GetEASEventID The GetEASEventID method returns the identifier of this emergency event. |
| ISCTE_EAS::GetExceptionCount The GetExceptionCount method returns the number of exception services. |
| ISCTE_EAS::GetExceptionService The GetExceptionService method returns information about an exception service. |
| ISCTE_EAS::GetLocationCodes The GetLocationCodes method returns location codes from the EAS table. |
| ISCTE_EAS::GetLocationCount The GetLocationCount method returns the number of locations in the EAS table. |
| ISCTE_EAS::GetNatureOfActivationText The GetNatureOfActivationText method gets a textual representation of the alert for a specified ISO 639 language code. |
| ISCTE_EAS::GetOriginatorCode The GetOriginatorCode method returns the EAS originator code. |
| ISCTE_EAS::GetProtocolVersion The GetProtocolVersion method returns the protocol version of the EAS table. |
| ISCTE_EAS::GetRawAlertText Gets the raw alert_text field from the EAS table. |
| ISCTE_EAS::GetRawAlertTextLen Gets the length of the alert_text field. |
| ISCTE_EAS::GetRawNatureOfActivationText Gets the raw nature_of_activation_text field from the EAS table. |
| ISCTE_EAS::GetRawNatureOfActivationTextLen Gets the length of the nature_of_activation_text field. |
| ISCTE_EAS::GetSequencyNumber The GetSequencyNumbermethod returns the sequence number. |
| ISCTE_EAS::GetStartTime The GetStartTime method returns the starting time of the alert. |
| ISCTE_EAS::GetTableDescriptorByIndex The GetTableDescriptorByIndex method returns a descriptor for the EAS table. |
| ISCTE_EAS::GetTableDescriptorByTag The GetTableDescriptorByTag method searches the EAS table for a descriptor with the specified descriptor tag. |
| ISCTE_EAS::GetTimeRemaining The GetTimeRemaining method returns the time that remains in the alert message. |
| ISCTE_EAS::GetVersionNumber The GetVersionNumber method returns the version number for the EAS table. |
| ISCTE_EAS::Initialize The Initialize method initializes the object using captured table section data. This method is called internally by the IAtscPsipParser::GetEAS method, so applications typically should not call it. |
