Low Latency Mode

Low Latency Mode reduces the overall latency by one frame.

Tessera T1 and M2 LED Processors work at a latency of 3 frames. In Low Latency Mode, the latency is reduced to 2 frames. Tessera S4 LED Processors are always in Low Latency Mode, and non-standard canvas sizes automatically switch the Tessera M2 and T1 LED Processors into Low Latency Mode.

NOTE:

When using several processors with different end to end latencies to run the same wall, video delay needs to be modified. See Combining Processors for more information.

Working in this mode, the following features are disabled:

• Scaling (upscaling and downscaling). As a result, the active area modifications are disabled
• Deinterlace
• Frame-rate conversion, forcing the processor to lock to the source framerate

Colour functions, such as contrast, brightness and RGB gain remain unaffected. The input source is set at its default resolution and sync frequency and is positioned 1:1 in the top left corner of the canvas.

The Tessera SX40 and Tessera S8 LED Processors do not have a Low Latency Mode, keeping all its features available at 2 frames latency end to end. To decrease their latency to 1 frame they can use Ultra Low Latency, though this has its own trade-offs. See Ultra Low Latency for more information.

NOTE:

Latency, or video delay, is defined as the time between the last cycle of a source frame appearing on the processor's input, and the first cycle that an LED on a fixture is lit with that frame.
