Abstract
In order to be able to identify television or video images (V1,V2) as identical, predeterminable parameters (H1, H2) of the images (V1, V2) to be tested are compared with each other. Images whose parameters, preferably the average brightness (H1, H2), fall within a predeterminable tolerance range, are identified as identical images. Thus, e.g. in a television reception equipment, particularly a mobile one, the images of all receivable transmitters are tested. Images identified as identical are allocated to the same transmitters or the same programs, the channels of which are stored as alternative channels. When there is bad reception or bad image quality an alternative channel is switched to.
