ENHANCING A VIDEO SIGNAL AT A REMOTE LOCATION

摘要

A system can be used to enhance a video of an event. Sensors (12, 14 and 16) are used at the event to acquire information. For example, the system can include pan, tilt and zoom sensors to acquire camera view information. This information can be added to the video signal from a camera (e.g. in the vertical blanking interval) or otherwise transmitted to a central studio. At the studio (36), the sensor information is used to enhance the video for broadcast. Example enhancements include drawing lines or other shapes in the video, adding advertisements to the video or adding other graphics to the video.
