Wireless RF signal from camera to video village and directing team — SDI or HDMI transmitted wirelessly. Lets director, producer, and script supervise live without blocking set.
Video Village Wireless / Picture Feed
On set, the camera is rolling, and the director is sitting 50 meters away in the Video Village — yet they can still see live what's going through the lens. This is made possible by wireless video transmission, a wireless radio system that transmits the camera signal to the director's station in real-time. Instead of running SDI or HDMI cables across half the shooting location, the camera sends its output encrypted wirelessly to monitors in the Village, the director's trailer, or on the Director's Monitor. The director and producer can follow along immediately and react instantly — without having to walk around on set and block the lighting.
Technically, this is achieved through proprietary wireless systems operating in the 5 GHz or 2.4 GHz band. The bandwidth must be large enough to handle uncompressed or minimally compressed HD/4K. At the same time, absolutely low latency is required — any delay exceeding approximately 100ms becomes unbearable because the director and camera are no longer speaking in "sync." Professional systems like Teradek, Sennheiser, or AJA work with redundant transmission channels, so failures or interference do not lead to signal dropouts.
In practice: The 1st AC calibrates focus together with the director, who judges the sharpness on their monitor in the Village — wireless video transmission makes this possible without the director standing on set and casting shadows. For complex digital effect shots or when grading is discussed live, the colorist also watches along in the Village. Script continuity also uses this system — they check if costumes or props are correct between shots.
However, the technology has its limitations: In environments with many other wireless systems (large studios, outdoor shoots near airports), frequency collisions can quickly occur. And the power consumption is significant — the transmitter unit on the camera drains the battery accordingly fast. On some sets, physical cables are still used from the follow-focus monitor directly to the camera because it's more reliable than wireless. But for mobile work, large shooting locations, or when the director needs to be spatially separated, wireless video transmission is standard today.
