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 converted to RGB565 format sent out to the LCD. Both PAL and NTSC
    formats are implemented in this application, selectable through a conditional
    compilation macro (NTSC_MODE).

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

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

Remove R2 - This resistor controls the orientation of the LCD output.
If not removed the output will be inverted.

2. External connections
-----------------------
    Connect a video source to the A-V EZ-Extender Video-in.

    Connect a NEC LCD flat cable to the A-V EZ-Extender P6.

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

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

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

- Connect a LCD display monitor

- Start the video source

- 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.

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.
