HDMI Transport System Project

HDMI-TS (HDMI Transport System) is low-latency HDMI video communication system by IP (Internet Protocol). Sophisticated interactions between remote places requires low-latency such as, cooperative-working, remote controle, etc... To this end, we developped sync method for video processing by hardware, RV-SYNC (Remote Virtical Sync). The latency to remote host is equivalent to Virtical Front Porch Periods (e.g. 25 lines on 720p) on no L2/L3 switches.
