Advertising digitally inserted into TV images
Virtual advertising is the use of digital technology to insert virtual advertising content into a live or pre-recorded television show, often in sports events.
This technique is often used to allow broadcasters to overlay existing physical advertising panels (on the playfield) with virtual content on the screen when broadcasting the same event in multiple regions; a Spanish football game will be broadcast in Mexico with Mexican advertising images. Similarly, virtual content can be inserted onto empty space within the sports venue such as the field of play, where physical advertising cannot be placed due to regulatory or safety reasons. Virtual advertising content is intended to be photo-realistic, so that the viewer has the impression they are seeing the real in-stadium advertising.
