OVERVIEW
========
    This application shows how to use ADV7183 device driver to read video frame and ADV7171 device
    driver to output video frame.

    The application first configures the decoder ADV7183 driver to read a single video frame from
    the video source, buffering the data in SDRAM and the driver is closed.
    When push button PB1 is pressed another frame is read.
    

    ADV7183 hardware registers can be accessed through TWI and device access service

3. Operational Description
--------------------------

- Open the "FrameCapture_537.dpj" project in the VisualDSP Integrated Development
  Environment (IDDE).

- Select via #define in FrameCaptureVideoOut.c the desired video input format e.g.
  //#define   PAL_FRAME (for NTSC - deafult)
  or
  #define   PAL_FRAME   (for PAL)

- Under the "Project" tab, select "Build Project" (program is then loaded automatically into DSP).

- Connect a video NTSC/PAL CVBS source to the bottom right connector of J7 (video in/out jack)

- Run the executables by pressing "run" (F5) on the toolbar.

- Stop the program after pushing PB1  

- You should view the input image.
