Module Name:

    EDevCtrl.h

Abstract:

    This header contain structures and peroperty sets for 
    interfacing to an external device, like a DV.
    The code is modeled after DirectShow's Vcrctrl Sample 
    (VCR Control Filter). It contain IAMExtDevice, 
    IAMExtTransport, and IAMTimecodeReader interfaces, and 
    a new interface IAMAdvancedAVControl() is added
    for additional advanced device controls.

    Note:  (From DShow DDK)
        The VCR control sample filter, Vcrctrl, is a simple 
        implementation of the external device control interfaces 
        that DirectShow provides. Vcrctrl provides basic transport 
        control and SMPTE timecode-reading capabilities for certain 
        Betacam and SVHS videocassette recorders with RS-422 or RS-232 
        serial interfaces (see source code for specific machine types 
        supported).

    Note:  some methods in IAM* interfaces may not be 
           used and will return not implemented.
