Syphon is created by Tom Butterworth and Anton Marini provides framework for VJ software. This framework is a library available connection between processes of image data on the identical host, and the architecture brought by IOSurface gives less delay. This utility allows image data as TCP/IP on network to realize network transparency. Compared with AirPlay, credibility might be lower, however this trait is small latency especially customized for VJ. By selecting the appropriate encode to network bandwidth you use, even on poor network environment it can carry out delivery without quality loss on image data.

We also provide UDPSyphon, TLRemoteCamera for iOS, TLSyphonViewer for iOS
