    Abstract: Elements necessary for a digital television receiver are structured as blocks that are a plurality of digital signal processing blocks and a host arithmetic operation processing block. The blocks are connected through a general-purpose bus. Commands for controlling operations of the blocks and data of streams are transferred through the bus. An extension plug-in card for a new service can be attached and detached to / from the bus. The extension plug-in card has hardware that accomplishes an extension function and a script for commands of the hardware. When the extension plug-in card is attached to the bus through an interface, the script for the commands is automatically uploaded to the host arithmetic operation processing block side. The host arithmetic operation processing block can operate the extension plug-in card corresponding to the transferred script for the commands.

    Abstract: Elements necessary for a digital television receiver are structured as a plurality of digital signal processing blocks and a host operation processing block. The blocks are connected through a general-purpose bus. Command for controlling the operations of the blocks and data of streams are transferred through the bus. Thus, by replacing only blocks, various types of digital television broadcasts that differ in carrier waves, modulating systems, and compressing systems can be handled. Consequently, the developing efficiency of a television receiver is improved. In addition, when a new service is started, by adding hardware for the service, the service can be easily handled.

    Abstract: Elements required for a digital television receiver are divided into a plurality of digital signal processor blocks and a host microprocessor block . The blocks are connected by general buses, through which commands and stream s of data are transferred to control the operations of the blocks. Plug-in extension cards detachable to the buses are provided for potential new services. The plug-in extension cards include hardware for implementing extended functions and store command scripts for the hardware. When a plug-i n extension card is connected to a bus through an interface, command scripts a re uploaded to the host microprocessor block that in turn operates the plug-in extension card based on the received command scripts.

    Abstract: A copyright protection method and apparatus, an output method and device, and a recording method and device for protecting information signals that are transmitted and stored in both a baseband signal status and a compressed encoded data status are provided. The method includes the stops of superimposing a first copyright protection information as a digital watermark on a signal in a baseband state, and compression encoding the signal in the baseband to form an information signal in a compressed encoded data state. The signal in the baseband and the signal in the compressed encoded data are then transmitted from a first apparatus to a second apparatus. The second apparatus determines whether rewriting of the first copyright protection information superimposed on the signal in the baseband and the signal in the compressed encoded data state is necessary, and if it is determined that rewriting of the first copyright protection information is necessary, rewriting the first copyright protection information as a digital watermark on the signal in said baseband state only.
