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.

A RECEIVER (2) HAVING A SIMPLE CONFIGURATION FOR RECEIVING AND DECODING DIGITAL BROADCASTS ADN OUPUTTING DECODED DATA TO AN EXTERNAL DEVICE AND MOREOVER, DECODING EXTERNALLY-INPUT DATA OUTPUTTING DECODED DATA TO AN EXTERNAL DEVICE. THERE ARE INCLUDED A RECEIVED-DATA DEMODULATING DEVICE (18) FOR RECEIVING AND DEMODULATING DIGITAL BROADCASTS AND GENERATING A FIRST CLOCK IN ACCORDANCE WITH THE DIGITAL BROADCAST AND A CLOCK GENERATING DEVICE (29) FOR GENERATING A THIRD CLOCK BY REQUENCY-DIVIDING A PREDETERMINED SECOND CLOCK. THE FIRST CLOCK IS USED WHEN THE DIGITAL BROADCAST IS RECEIVED AND DECODED AND THE THIRD CLOCK IS USED WHEN EXTERNALLY-INPUTTED DATA IS DECODED.FIG. 2

Abstract:
A switching portion of an IRD supplies a non-descrambled TS (transport stream) received from a front end portion or a descrambled TS received from a descrambler to a DVCR connected to an IEEE 1394 interface. In addition, data received from the DVCR is supplied to the descrambler.

Abstract:
In an IRD, a switching section supplies a TS (Transport Stream) which is not descrambled yet and outputted by a front end section or a descrambled TS outputted by a descrambler to a DVCR connected to an IEEE-1394 interface and supplies the data outputted by the DVCR to the descrambler.
Abstract:
PROBLEM TO BE SOLVED: To broadcast a video image of a content without combining the video image of the content with a video image of a sign language corresponding to the video image of the content, and to display the video image of the content by combining the video image of the content with the video image of the sign language corresponding to the video image of the content at a receiving side without generating any great processing loads. SOLUTION: In a step S12, a content signal is reproduced by a monitor 5, and an operator viewing the content signal recognizes a sign language word appearing in the voice of the content signal to operate a sign language word identification number input section 52. In a step S14, the sign language word identification number input section 52 generates sign language word identification information in response to the operation of the operator to output it to a multiplexing part 37 as a DSM-CC event message. The multiplexing part 37 generates a broadcast stream by multiplexing a content encoded signal, the DSM-CC event message containing the sign language word identification information, and a data carousel module storing a sign language word image group. Thus, the application to a television broadcasting system can be achieved. COPYRIGHT: (C)2011,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a broadcast system for flexibly coping with a variety of service models. SOLUTION: A broadcast station 1 provides a mobile broadcast service. PSI added to a stream transmitted from the broadcast station 1 includes a digital copy control descriptor. For a value of "copy_control_type" of the digital copy control descriptor, not only 01b and 11b, which have been conventionally used, but 10b are also used. In a mobile receiver 2, the digital copy control descriptor is analyzed, and in the case it is decided that the "copy_control_type" is 10b, then record or output of contents is controlled according to the meaning of "security_type". By "security_type", a constraint adaptive to a mobile broadcast service is represented such as exclusively an internal memory is permitted to record contents and an external output is forbidden. The present invention is applied to a receiver device for receiving a digital broadcast. COPYRIGHT: (C)2011,JPO&INPIT

PROBLEM TO BE SOLVED: To flexibly input/output digital data. SOLUTION: In an IRD 5, a switching section 21 is configured to provide, to a DVCR 7 connected to an IEEE-1394 interface 22, a non-descrambled TS (transport stream) outputted by a front end section 11 or a descrambled TS outputted by a descrambler 12, and to provide, to the descrambler 12, data outputted by the DVCR 7.

Abstract:
PROBLEM TO BE SOLVED: To protect copyright of a move and a pause of a contents provider. SOLUTION: Move- Pause descriptors are written onto a PMT which is multiplexed in a transport stream TS. A CPU 101 controls move and pause processes based on the description of the Move- Pause descriptors. In the Move- Pause descriptors, information such as the propriety of a move, the number of possibilities for a move, the propriety of a pause, the number of possibilities for reproducing a pause and an accumulation limit of the pause is described. When a copying of the stream TS is not prohibited in the move process, the stream TS accumulated in an HDD 106 is moved to a recorder 240 without changing the generation information of the copy. When a copying of the stream TS is prohibited in the pause process, the stream TS is not outputted to an output device (a monitor device 230) and the stream TS is accumulated is the HDD 106. Then, after that, the accumulated stream TS is read and outputted to the output device.
