Transmitting apparatus, transmitting method, receiving apparatus, receiving method, computer program, and broadcasting system

The protection of data against illicit transfer with respect to specific data can be ensured. An integrated receiver decoder determines whether or not ATRAC (Adaptive Transform Acoustic Coding) data requiring authentication is contained in selected piece-of-music data in accordance with determination data added into transmitted data. When ATRAC data requiring authentication is contained, the integrated receiver decoder performs an authentication process between it and a storage which is a transfer destination of the ATRAC data, and performs downloading of the ATRAC data after confirming that the storage is a valid apparatus to which the downloading may be performed.

Data transmission apparatus and method, data receiving apparatus and method, and data transmission and reception system and method

To compensate a failure in downloading of music piece data. For example, when a viewer instructs purchase of a music pieceC to an IRD at a timing tduring the sixth transmission of music piece data, the music piece data to be transmitted for the seventh time immediately after the instruction is usually downloaded. When the downloading of the music piece data transmitted for the seventh time fails for some reason, downloading is re-executed on music piece data to be transmitted for the eighth time. The music piece data for the final transmission time in each of musical pieces is used for re-execution. Timing at which downloading of the music piece data transmitted for the time immediately preceding the final time can be instructed is set as purchase limit time by using elapsed time since program start time.

Apparatus and method for receiving a transport stream containing a plurality of content data

A transmission/reception system includes a providing apparatus and a recording apparatus. The providing apparatus has a generating section which generates restrictive information for each piece of content to be broadcast, and a providing section which provides the restrictive information by broadcasting to the recording apparatus. The recording apparatus has a management section which manages the restrictive information, and a restriction section that adds a restriction to at least one of a next copying of the same content as copied last or each piece of the recorded content that provided a source of the copying.

Transmission/reception system, recording apparatus and method, providing apparatus and method, and program

A digital broadcast, in which video data and audio data are transmitted in the form of a transport stream, is received in a digital broadcast receiver and is decoded to provide a received transport stream. A first interface of the digital broadcast receiver is connected to a corresponding interface of a recording apparatus. Information corresponding to a transmission rate of the received transport stream is determined. A recording rate setting command is generated on the basis of the information corresponding to the transmission rate. The recording rate setting command is transmitted to the recording apparatus through the first interface and the corresponding interface when the connection between the first interface and the corresponding interface is initiated, when a request command is received from the recording apparatus, or periodically after predetermined intervals.

Setting rate for recording broadcast transmission according to transmission rate

A digital broadcast receiver receives and decodes a digital broadcast containing video data and audio data transmitted in the form of a transport stream. An interface supports communication with a recording apparatus. The receiver determines information corresponding to a transmission rate of a received transport stream of a received digital broadcast. The receiver also generates a recording rate setting command on the basis of the information corresponding to the transmission rate and transmits the recording rate setting command to the recording apparatus through the interface when a connection between the recording apparatus and the interface is initiated, when a request command is received from the recording apparatus, or periodically after predetermined intervals.

When a transport stream is transmitted between each unit connected through an interface, if any data which is not permitted to be transmitted on a partial transport stream is transmitted, information of this section is transmitted as a private section or a user private. As a result, information of a section of an EIT can be transmitted from for example a digital satellite broadcast tuner to a personal computer and an original program schedule list can be created on the personal computer.

Information transfer apparatus and method, information processing apparatus and method, and information processing system

The invention relates to properly protecting broadcast contents stored on a receiver side from copying without permission and illegal use in server type broadcasting. According to the invention, contents are sent from a broadcast sending side in a state in which copyright information for the contents is added to the contents. On the other hand, on a receiving client side applicable to server type digital broadcasting, it is possible to perform appropriate control for reproduction of contents and recording reservation on the basis of copyright information for contents such as the number of times of reproduction of contents, restriction of display resolution at the time of reproduction of contents, and an expiration date of content reproduction. According to this copyright information, it is possible to perform detailed control for a display device incorporated in or connected to a receiver.

Content delivery system, content delivery apparatus, content recording and reproduction apparatus and content recording and reproduction method, and computer program

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.
