Court video: director, sound, gestures and face blur

Court cameras do more than record. The stream switches shots by itself from the players' positions, the recording carries the court sound, the best moment is marked with a gesture — both hands above the head — and bystanders' faces are blurred in everything that leaves the court. The video here is one court 4 rally from four cameras.

A real match: one rally from the court cameras; faces and signs blurred

What it is and why

A court has several cameras from different sides plus cameras. The system knows where every player is in 3D and uses it for video: it picks the best shot for the stream, recognises a player's gesture and tells match players from bystanders to blur only those who did not ask to be filmed.

What it does

Court video

  • A Director camera in the broadcast: the shot follows the players, no camera operator
  • Both hands above the head — the moment is marked for highlights
  • Faces of spectators and players on other courts are blurred in everything that leaves the court
What the court needs

How it works

How it works

  1. Cameras film

    Cameras in the corners and cameras film the game; the system tracks players in 3D.

  2. Stream director

    The stream switches to the camera that sees more players and is closer to the rally; a shot holds at least 10 seconds.

  3. Gesture

    A player raises both hands above the head for about a second — the moment is marked for clips.

  4. Who is a bystander

    A person on court is a player, outside the walls a bystander.

  5. Blur

    Before upload, bystanders' faces are blurred in highlights, moments and the match recording.

In detail

Court video

Broadcast director: the camera is chosen automatically

The court broadcast has a Director camera: it switches between court cameras by the players' 3D positions — taking the one that sees more players and is closer to the rally. A shot is held for at least 10 seconds, and between rallies a wide shot is shown. The video is not re-encoded: the broadcast is assembled from ready camera segments.

Marking a moment with a gesture

A player raises both hands above the head and holds them for about a second — the system marks the moment for highlights, just like the button on the terminal. A smash or a serve raises the hands only for a split second and in motion, so they do not count. The same player can mark another moment after 20 seconds.

Bystanders' faces blurred

The players of the match stay as they are, while the faces of spectators behind the glass, players on other courts and staff are blurred in everything that leaves the system: highlights, moments and the match recording.

Limits, honestly

Limits, honestly

  • Smashes and serves raise the hands for a split second and in motion — not counted as a gesture; the same player can repeat a gesture after 20 seconds.
  • Only bystanders are blurred; match players stay as they are.
  • The director picks among court cameras — no TV-style close-ups.
