Abstract
Images are transmitted from a server through a cellular network and displayed on a mobile phone. After a predefined time of non-use or via input of a user command, the mobile phone is switched into an inactive mode. When an activating operation is performed, the phone is switched from inactive into locked active mode. An unlocking operation switches the phone from locked active into unlocked active mode. User input is accepted only in unlocked active mode. The server selects a number of images and transmits them to the mobile phone. One of the transmitted images is selected and kept available for display, during locked active mode, the selected image is displayed. A count indicates how many times an image has been displayed, and the count value for each image is transmitted from the mobile phone to the server.
