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: Elements necessary for a digital television receiver are structured as 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 a stream are transferred through the bus. When an encryption encoder /decode is disposed in each block, contents transferred through the bus can be protected. When an encryption encoder / decode circuit is disposed in an interface to which an extension plug-in card is attached, contents that are output from the interface can be protected.
