LTP stands for "latest takes precedence" and is a method of merging DMX data from multiple sources. LTP is cheaper in terms of memory to implement that HTP because it only requires two buffers.
Example (using an 8 channel output buffer).
| Source A Data | Source B Data | Output Buffer | |
|---|---|---|---|
| Initial State | 0 0 0 0 0 0 0 0 | ||
| First frame from Source A | 4 7 9 10 | 4 7 9 10 0 0 0 0 | |
| Frame from Source B | 1 3 | 1 3 9 10 0 0 0 0 | |
| Second frame from Source A | 1 2 3 4 5 6 | 1 2 3 4 5 6 0 0 |
