Running the Demos in Standalone Mode
Running the Demonstration Software 3-3
The Capture/Display mode uses D1 format for video display. D1 has a
resolution of 720 × 480 pixels if you are using NTSC and 720 × 576 pixels
if you are using PAL.
The Encode/Decode Loopback mode uses CIF format for video display.
CIF (Common Intermediate Format) video format, when using NTSC,
has a resolution of 352 x 240 pixels and a frame rate of about 30 frames
per second. If you are using PAL, CIF has a resolution of 352 x 288 pixels
and a frame rate of about 25 frames per second.
The demo also reads the SW4-3 switch (the rightmost switch when
looking at the board edge-on) at startup and enables audio output if the
switch is in the DOWN position.
To restart the demo, you can press the Reset button (SW6), which resets
the DSP chip.
Note: Avoid using SW5. In contrast to SW6, the nPOR (power-on
reset) button (SW5) resets everything on the board, including the
on-board emulator—resulting in a need to restart Code Composer
Studio if you were using it.
