low-latency audio and video network transmission system
UltraGrid brought by CESNET's Laboratory of Advanced Networking Technologies (Sitola) is a software implementation of high-quality low-latency video and audio transmissions using commodity PC and Mac hardware. Supported resolutions range through HD (1920x1080) up to 4K (4096x2160) with up to 60 frames per second. The high-quality is achieved either by using uncompressed streams or streams with very low compression ratio. End-to-end transmission latency (i.e., all the way from the camera to the display) is about 100ms, but it varies based on camera and capture cards being used. UltraGrid was originally a research project used to demonstrate the possibilities of 10Gbps networks and to study multi-point data distribution in such environments. Recent advances in the field of GPU-accelerated low-latency codecs extend its usability also to Gigabit networks. Nowadays, main application areas are collaborative environments, medical, cinematography and broadcasting applications, as well as various educational activities.
