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.
    Then the encoder ADV7171 driver is opened for sending out the buffered video frame to the video
    monitor continuosly until push button SW4 is pressed and the encoder driver is closed.
    The process then repeats, until push button SW7 is pressed. When the button is pressed, the
    program is terminated.

    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 circular buffer, selectable through
    a conditional compilation macro (USE_CIRCULAR)

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

RUNNING THE APPLICATION
=======================

1. Hardware Settings
--------------------
ADSP-BF533 EZ-KIT LITE SETTINGS:
--------------------------------
SW1: 1-OFF 2-OFF 3-OFF 4-OFF 5-OFF 6-OFF
SW2: 1-OFF 2-OFF 3-OFF 4-OFF 5-OFF 6-OFF
SW3: 1-OFF 2-OFF 3-OFF 4-OFF 5-OFF 6-ON
SW9: 1-ON  2-ON  3-ON  4-ON  5-OFF 6-OFF
SW10 1-ON  2-ON
SW11 1-OFF 2-ON
SW12 1-ON  2-ON  3-ON  4-ON

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 J8.

                                                J8
            +---------------------------------------------------+
            |          O          O < Video Out  O              |    (white)
            |          O          O              O < Video In   |   (red)
            +---------------------------------------------------+

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

- Open the "FrameCaptureVideoOut_533.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 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 "run" (F5) on the toolbar.
  You should see a copy of the input video in the output screen.

- Press pushbutton SW4 to capture a new video frame

- Press pushbutton SW7 to terminate the program
