The IATSCLocator interface is implemented on the ATSCLocator object and contains methods that enable the network provider to determine the physical channel and transport stream ID of an ATSC transmission. Applications do not use Locator interfaces except possibly for debugging purposes. All Locator objects also support IPersistPropertyBag.
In addition to the methods inherited from IUnknown and ILocator, the IATSCLocator interface exposes the following methods.
| Method | Description |
| get_PhysicalChannel | Retrieves the physical channel. |
| get_TSID | Retrieves the transport stream ID. |
| put_PhysicalChannel | Sets the physical channel. |
| put_TSID | Sets the transport stream ID. |
