AI Technical Summary
Existing systems for digital perimeter advertising in sports broadcasting require costly post-processing to achieve regional adaptation of advertisements for television broadcasts, disrupting the original display and increasing technical complexity.
Digital perimeter displays emit coded light pulses undetectable to the human eye, which are captured by television cameras and converted into locally adapted advertising images in real-time by an image processing unit, allowing automatic and individual exchange of advertisements without affecting stadium viewers.
Enables real-time regional adaptation of advertisements for television broadcasts while maintaining the original display for stadium visitors, reducing costs and technical complexity.

Abstract
Description
3. Technical field:
[0001] Audiovisual signal processing, sports broadcasting, digital advertising
[0002] The invention relates to visual signal processing in the field of illuminated advertising, for example in sports broadcasting, in particular the targeted insertion of regionally adapted advertising into television images by optical coding of digital displays, for example perimeter displays in stadiums. 4. Brief description of the invention:
[0003] The invention relates to a device for the individual display of advertising in television broadcasts of, for example, sporting events. Digital displays, such as perimeter boards in stadiums, emit coded light pulses that are invisible to the human eye but are detected by television cameras and converted into locally adapted advertising images by an image processing unit. The original advertisement remains visible to visitors on site, while television viewers worldwide are shown a regionally adapted advertising image in real time. 4.1 State of the art using the example of sports broadcasting:
[0004] Digital perimeter advertising is established in modern stadiums and is displayed via LED screens. Television cameras record this advertising and transmit it unchanged to viewers worldwide. Regional adaptation of the advertising is currently only possible through separate overlays in the studio or digital post-processing, which entails high technical requirements and costs. 4.2 Problem statement using the example of sports broadcasting:
[0005] There is a need for a system that allows advertising shown in stadiums to be automatically and individually exchanged for television broadcasts, without disturbing stadium visitors and without costly post-processing. 4.3 Technical solution using the example of sports broadcasting:
[0006] The invention solves this problem with a system in which digital perimeter displays emit coded light pulses that are invisible to the human eye but are captured by television cameras and converted into a locally adapted advertising image by an image processing unit. The original advertisement remains visible to stadium visitors, while television viewers worldwide are shown a regionally adapted advertising image – preferably as a picture-in-picture display. 4.4 Design: • Digital barrier displays send modulated light pulses (e.g., PWM, frequency modulation, spectral coding). • Cameras with optical filters capture these impulses synchronously with the live transmission. • An image processing unit decodes the advertising content and replaces it in real time, recording, playback and still image (TV and photography) with locally controlled advertising. • The advertisement is displayed as a picture-in-picture in place of the advertisement shown in the stadium, without covering the main image. • The selection of advertisements is automated based on geolocation or user profiles.
