About the Media State Aggregation Service
The Windows Media Center interface is for viewing and recording TV, viewing pictures and videos, and playing audio from files or CD. The software provides media status information such as track or channel numbers and time elapsed. This information can be retrieved by a device driver—which can use it to refresh a front panel display (FPD)—or by any software component that must receive information about the state of Windows Media Center.
This section describes the components of the media state aggregation service (MSAS), explains how to use Component Object Model (COM) interfaces to retrieve media status information, and provides a complete reference for the interfaces.
