The invention is directed to a device for casting strands of metal, in particular steel, with a material supply vessel, the liquid metal being delivered to the carrying side of a circulating conveyor belt by means of the pouring nozzle of the material supply vessel. The high emitter resistivity found in prior homojunction devices is circumvented using a low work function material layer in forming the emitter. Real embedding information is formed such that a redundancy bit with a fixed length that is used for an error correction of an information bit is added immediately after the information bit in which the packing data is subdivided into data each having a fixed length. An image of the thus-stored original image data is displayed on the digitizer-integrated LCD. A fold line extends from the outer edge to a portion of the groove. The order of the cell information in the PGC information corresponds to the order in which the objects are played back.
