AI Technical Summary

Technical Problem

In filming studios with multiple cameras, accurately previewing the image from a new camera position is challenging due to the three-dimensional scene appearing distorted when projected onto a two-dimensional display wall, requiring significant data processing and bandwidth to generate and transmit appropriate backgrounds for each camera.

Method used

A system comprising a display controller and production controller that alternately displays a high-resolution background image and a monochrome image on the display wall, allowing chroma-key processing to replace portions of the image from a non-active camera, enabling selective frame capture and reducing bandwidth requirements by using a command message to display a monochrome image without pixel mapping data.

Benefits of technology

Enables producers to realistically envision the image from any active camera position, reducing data processing and bandwidth needs while ensuring accurate representation of the background for each camera, improving operational efficiency in multi-camera setups.

Abstract

A display controller (8) for a video capture system, the display controller (8) comprising one or more processors (13) configured to: receive an indication of a first location of an active camera (3, 4, 5) and a second location of a non-active camera (3, 4, 5); receive a definition of a three-dimensional scene; form first and second representations of the scene from the first and second locations respectively; and transmit the first representation to a display wall (2) and the second representation to a production controller (6).
