KINDS (Key INformation Display System), a prompt election reporting system for TV broadcasting, has been developed and was applied to the election of the House of Councillors on 12 July 1998. The system superimposes the elected candidates' names on the various pictures broadcast by each local NHK station simultaneously, synchronously and promptly. Images of the names are encoded by a new method which uses arithmetic coding and achieves high compression rates without information loss. A multicast/IP protocol is used for transmitting the codes to the local stations via an Ethernet LAN. This achieves rapid transmission of the codes with reduced traffic volume. An overview of the system is reported.
