                            Theory of operation


    The Device Interface Library (DIL) allows application level code, such
as a DirectShow filter, to access the Broadcom CrystalHD decoder driver to 
provide hardware decoding for MPEG-2, H.264 (AVC) and VC-1 streams.

    In the Microsoft DirectShow system, the overall system graph would look 
like the following:

+--------+  +---------------+  +---------------+  +--------------------+
| Source |->| Demultiplexer |->| Audio decoder |->| DirectSound Device |
+--------+  +---------------+  +---------------+  +--------------------+
                    |
                    |  +-------------------------+  +----------------+
                    +->| Broadcom decoder filter |->| Video Renderer |
                       +-------------------------+  +----------------+
                                  |    |  
                            +----------------+
                            |  Broadcom DIL  |
                            +----------------+
                                  |    |
                            +-----------------+
                            | Broadcom Driver |
                            +-----------------+

    From the view of the caller, the DIL will accept compressed video streams
and will output decoded video frames or fields to seperate Y and UV buffers.
The DIL is responsible solely for decoding video and has no responsibilities
for audio nor for rendering, as shown in the above diagram.  Audio/video
sychronization is assisted by feeding the DIL with timestamps so that it
may pass those timestamps along with the decoded video.  The timestamped
output video will then be presented at the appropriate time by the renderer.

A minimal implementation would be:

    HANDLE              hBRCMhandle;
    uint8_t             input_buffer[INPUT_SIZE];
    uint8_t             y_output_buffer[WIDTH*HEIGHT];
    uint8_t             uv_output_buffer[WIDTH*HEIGHT];
    BC_DTS_PROC_OUT     sProcOutData = { fill in your values here };
    BC_PIC_INFO_BLOCK   sPIB = { fill in your values here };

    // Acquire handle for device.
    DtsDeviceOpen(&hBRCMhandle, 0);
     
    // Elemental stream.
    DtsOpenDecoder(hBRCMhandle, 0);
    
    // H.264, Enable FGT SEI, do not parse metadata, no forced progressive out
    DtsSetVideoParams(hBRCMhandle,0,1,0,0,0);

    // Tell decoder to wait for input from host. (PC)
    DtsStartDecoder(hBRCMhandle);       

    // Input buffer address, input buffer size, no timestamp, Unencrypted
    DtsProcInput(hBRCMhandle,input_buffer,sizeof(input_buffer),0,0);

    // Tell PC to wait for data from decoder.
    DtsStartCapture(hBRCMhandle);       

    // 16ms timeout, pass pointer to PIB then get the decoded picture.
    DtsProcOutput(hBRCMhandle,16,&sPIB);

    // Stop the decoder.
    DtsStopDecoder(hBRCMhandle);

    // Close the decoder
    DtsCloseDecoder(hBRCMhandle);

    // Release handle for device.
    DtsDeviceClose(hBRCMhandle);

    Progressive     Instruct decoder to always try to send back progressive

    milliSecWait    Timeout parameter. DtsProcOutput will fail is no picture
                    is received in this time.
    *pOut           This is a pointer to the BC_DTS_PROC_OUT structure that is
                    allocated by the caller. The decoded picture is returned
                    in this structure. This structure is described in the

                    Data is copied from the decoder to the buffers before this
                    function returns. [INPUT/OUTPUT]

/*****************************************************************************

Function name:

    DtsProcOutputNoCopy

Description:

    Returns one decoded picture to the caller. Functionality of this API()
    is very similar to ProcOutPut() API. This API will not copy the video data
    to caller's buffers but provides the source buffer pointers in pOut structure.

    This is more secure and preferred method for BCM's Link hardware. The actual
    format conversion/copy routines are provided as part of the Filter/Security
    layer source code. Using this method, all the clear data handling will be
    done by bcmDFilter or bcmSec layers which are expected to be in Player's
    tamper resistant area.

    == NOTE ====
     1) DtsReleaseOutputBuffs() interface must be called to release the buffers
        back to DIL if return Status is BC_STS_SUCCESS.

     2) Only this interface supports PIB and full 100% output encryption/Scrambling.


    The device must have been previously opened for this call to succeed.

Parameters:

    hDevice         Handle to device. This is obtained via a prior call to

                    allocated by the caller. The decoded picture is returned
