Abstract: An electronic shelf label system, comprising a number of display devices to display content on its screen or its screens, each device comprises a memory stage to store content data, and a control stage to control the display of the content on its screen; wherein the screen is a video screen and realizes a shelf rail or covers a front of a shelf rail or a part of it to which it is attachable, and the content is a video and the memory stage stores the entire video data of the video, and the control stage is designed to define a display window for the video and to display only the video content within the display window on its screen.

Abstract: The invention relates to an electronic shelf label system that comprises a server for delivering shelf label display information to a number of display devices that are controlled by the server to display said shelf label display information on their screens, wherein said screen is designed to display video content represented by received video data, and said display device is designed to deliver video data to a screen and to receive label positioning data for defining the position of the shelf label display information in the display area of at least one of the screens connected to it, and to embed the shelf label display information in accordance with the received location data in the video content that is delivered to said screen.

Abstract: The invention relates to a base station or a radio access point having a plurality of radio modules, of which one communicates with electronic price indication signs. If a plurality of radio modules use the same frequencies and communicate simultaneously, disturbances can occur in the form of interference. The invention solves this problem in that the radio modules (21, 22, 23) are coupled (24) such that a radio module (22) can influence another radio module (21, 23) with regard to the radio activity of said other radio module. In particular, the radio module that communicates with the electronic price indication signs (22) can silence the other radio modules (21, 23) by means of a radio activity control signal (FS).
