Packetized Display Protocol

One of the key technologies CDS has is a Packetized Display Protocol (PDP). PDP is a physical layer independent method of pixel data transmission capable of providing latency guarantees while maximizing performance. The goal with PDP is to send small sub-windows of data at a faster apparent frame rate, to be able to decode and display anywhere on the array, and maintain support for full resolution modes of operations.

800Hz, 100Hz, 2Hz

Displaying a scene with three (3) different frame rates: 800hz bouncing number, 100hz background of numbers (small numbers displayed on the whole scene), and 2hz large number. Recorded at 100hz. New compositor, PDP firmware, and command-line PDP display are working.

Multi-Frame Scene

PDP 100Hz Background with 800Hz Hot Object Demo taken at Air Force Research Lab (AFRL) on NSLEDS 5

20KHz Frame Rate

20KHz PDP demo with a Hot Object moving across the 1024x1024 spatial resolution IRLED array. The scene is heavily slowed down as indicated by the timestamp. The scene was captured using FLIR's latest X69 series IR cameras which then had to be windowed down extensively to match CDS' 20KHz IRLED Scene Projector  System.

1000Hz & 100Hz

Multi Frame rate scene using CDS PDP technology with a background (mountain) being displayed at 100Hz frame rate and the three (3) hot objects operating at 1000KHz.
