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 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.

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. According t o the method, replacing blocks is only needed to adapt a variety of digital television broadcasting systems of different carriers, different modulation techniques and different compression techniques, thus increasing the efficiency in development. It is also adaptable to new services easily by providing additional hardware.

Abstract: A stereo microphone unit adapted to be installed in a video camera or the like, comprising a cabinet, two nondirectional microphones disposed with a predetermined distance therebetween on the wall of the cabinet for collecting outside sound signal, delay means for delaying each output of the microphones by a time period corresponding to the predetermined distance, and subtracter means for subtracting the output of the delay means relative to one microphone from the output of the other microphone. A stereo audio signal is provided only with regard to the output sound signal of any frequency lower than a predetermined frequency of 6 kHz or so.
