Creating Pattern Sequences
2.8.2 External Pattern Sequences Streaming from HDMI Port
To create an external pattern sequence follow these steps:
1. Set the display mode as "HDMI Port".
2. Select "External Streaming Pattern Sequence" in the "HDMI Port" tab. See
.
3. Set the LED Select.
4. Set the Color Bit Depth.
5. Set the Frame Rate.
6. Click "Set."
•
The GUI calculates the patterns per frame and pattern rate from the bit depth and frame rate.
•
The resolution in "External Streaming Pattern Sequence" mode cannot be changed. The video
stream must supply frames with a 608 × 684 pixel resolution.

2.8.3 Extended Pattern Sequences
In addition to the high-speed internal stored pattern sequences, DLP LightCrafter can run extended
pattern sequences that allows more than 96 patterns and exposure times up to 5 seconds.
pattern sequences that allows more than 96 patterns and exposure times up to 5 seconds.

There are
some constraints to the extended pattern sequence mode:
•
Sequences with more than 96 patterns:
–
Maximum of 1050 patterns for 1-bit per pixel patterns
–
Maximum of 131 patterns for 8-bit per pixel patterns
•
Longer exposures than 20 ms:
–
Maximum exposure of 5 second for 8-bit per pixel patterns
–
Maximum exposure of 2 second for 1-bit per pixel patterns
•
Minimum trigger period of 18 ms
•
Minimum exposure of 5 ms
•
"Play Once" not supported
•
A 330 µs dark frame occurs every 20 ms
•
"Multiple Bit and Multiple Color" mode not supported
(1)
Multiple bit and multiple color pattern sequences are not enabled in extended pattern sequence mode.
