METHOD OF DISTRIBUTING DATA PACKET OF SYSTEM SOFTWARE

PROBLEM TO BE SOLVED: To provide a method for simply updating a data packet of system software. SOLUTION: 1. An announce signal containing the information that new system software or a part thereof is subsequently transferred is transmitted from a server to all decoders simultaneously. 2. The system software or a part thereof is transferred in the form of data packets from the server to all decoders simultaneously. By the advance information in the form of an announce signal which is transmitted to all decoders by the broadcast method, the decoders are notified of the forthcoming transmission of the current version of the system software, whereupon they can prepare for the reception of the new version. The new version is also transmitted by the broadcast method, and ideally only once. COPYRIGHT: (C)2009,JPO&INPIT
