OVERVIEW
========
    This application shows how to perform the video acquisiton in ITU-656 mode from
    the decoder ADV7183, buffering the data in SDRAM. The buffered video frame
    is then sent out to the video monitor. In this application, no processing is
    done on buffered video frames. Both PAL and NTSC formats are implemented in
    this application, selectable through a conditional compilation macro
    (PAL_FRAME). This application uses a chained or chained with loopback dataflow
    method, selectable through a conditional compilation macro (USE_LOOPBACK)

    ADV7183 and ADV7179 hardware registers can be accessed through pseudo TWI and
    device access service.

    Pushbutton (SW9) can be used to terminate this application.

2. External connections
-----------------------
    Connect a monitor to the EZ-Kit video-out connector and a video source
    to the EZ-Kit video-in. The video connectors are the bank of 6 RCA-style
    jacks nearest the serial cable connector on the EZ-Kit labeled as J6.

            +---------------------------------------------------+
            |          O          O < Video Out  O              |      (white)
            |          O          O              O < Video In   |     (red)
            +---------------------------------------------------+ J6

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

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

- Select via #define in VideoInVideoOut.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 J6 (video in/out jack)

- Connect a video display monitor to the video output jack (top middle connector of J6)

- Run the executables by pressing "multiprocessor run" (CTRL-F5) on the toolbar. DO NOT use the
  single core (F5) button. You should see a copy of the input video in the output screen.

- Halt the processor ("multiprocessor halt" button). If you open a memory window and go to the
  addresses of sFrame0,1,2,3, you see the video data of the four frames.

4. Project Build Optimization
-----------------------------
    Please note that for this project in Debug Mode, code optimizations have
    been enabled.

    This is done via the menu
    Project -> Project Options
               - Project - Compile - Code Generation - Enable optimization [X]

    Code optimizations improve the speed of applications by transforming
    certain code segments.
