UltraGrid Software

UltraGrid is a software implementation of high-quality low-latency video and audio transmissions using commodity Windows and macOS hardware. UltraGrid uses uncompressed or very high quality compression streams to achieve up to 4K/UHD 60p resolution with as low as 100ms end-to-end latency. UltraGrid is used, among others, in areas like collaborative environments, medical cinematography, broadcasting application and various educational activities. 

SITOLA's UltraGrid is based on the original UltraGrid, a research project used to demonstrate the possibilities of 10Gbps networks and to study multi-point data distribution in such environments. Due to recent advances in the field of GPU-accelerated low-latency codecs, we have been able to extend its usability also to Gigabit networks.

Bluefish444 KRONOS and Epoch video I/O cards can be used with UltraGrid for both input and/or output.
