TITLE
-----
VPORT example (video)
USAGE
-----
These examples test the video driver on the DM***2 EVM board. The applications
use the vportcap and vportdis video mini drivers for video capture and display.
The examples cover all supported video formats by the DM***2 EVM:
Capture:
- Standard-Definition TV: NTSC/PAL
Display:
- Standard-Definition TV: NTSC/PAL
- 16-bit RGB: VGA(***0x480@60Hz), SVGA(800x600@60Hz), XGA(1024x768@60Hz).
- High-Definition TV: 480p@60fps, 720p@60fps, 1080i@30fps
DESCRIPTION
-----------
There are four CCS projects used to build the examples: ntsc.pjt, pal.pjt,
vga.pjt, and hd.pjt.
These projects cover examples in NTSC, PAL, VGA and HD video formats. In
each project, there are three configurations:
- DISPLAY_ONLY: Displays a runing color bar.
- LOOPBACK: capture and display loop-back.
- LOOPBACK_PIP: dual-capture and picture in picture display.
The examples use the videoport display minidriver to open the videoport 0 & 1
in capture mode and the video port 2 in display mode. It then programs the
video decoders and encoder on the EVM***2 board through I2C before starting
capture or display operations.
TESTING
-------
To run the examples, the following equipment is required:
- For NTSC examples:
* A NTSC compatible camera with composite(RCA) output.
* A NTSC compatible TV monitor with composite or S-Video inputs.
- For PAL examples:
* A PAL compatible camera with composite(RCA) output.
* A PAL compatible TV monitor with composite or S-Video inputs.
- For RGB examples:
* A NTSC compatible camera with composite(RCA) output.
* A computer monitor that is capable of displaying VGA@60Hz, SVGA@60Hz and
XGA@60Hz.
- For HD examples:
* A NTSC compatible camera with composite(RCA) output.
* A High-Definition monitor that supports the following HD formats:
480p@60fps, 720p@60fps and 1080i@30fps.
KNOWN PROBLEMS
--------------
The video driver document (SPRA918) omitted the irqId element from the VPORTCAP_Params and
the VPORTDIS_Params structures. This element sets the EDMA interrupt ID.
