| 20080294802 | Stream processing device and storage device - The invention provides a stream data control module which can easily achieve a function expansion of a digital device and can simply, safely and inexpensively realize the recording and reproducing of stream data for a storage device. A stream data control module includes a stream I/F unit exclusively inputting and outputting stream data, a non-stream I/F unit inputting and outputting non-stream data, a device I/F unit providing an interface to data storage means, and a control unit executing a transfer process of the stream data in response to a recording command and a reproducing command given from host means. The control unit has a stream arrangement management unit managing a storing position of the stream data in the data storage means, a scheduling unit controlling a transfer order of the stream data and the non-stream data, and a command processing unit interpreting various commands given from the host means. | 11-27-2008 |
| 20090113087 | STREAM DATA TRANSFER CONTROL DEVICE - There are provided a stream I/F section | 04-30-2009 |
| 20090222798 | Information Processing Apparatus - A mobile device includes a memory for storing therein a subroutine management table to manage kinds of existing codes out of native code, first code and second code for a plurality of subroutines contained in content, a virtual machine, a precompile circuit for producing second code from first code and a subroutine management circuit for changing over processing in accordance with the kind of existing code for subroutine called up during execution of content. The subroutine management circuit judges kind of existing code with reference to the subroutine management table when the processing is changed over. | 09-03-2009 |
| 20090316891 | CONTENT REPRODUCTION APPARATUS, RECORDING APPARATUS, RECORDING AND REPRODUCTION APPARATUS, AND REPRODUCTION METHOD - In an apparatus of reproducing contents in which an encryption key is to be changed at predetermined intervals for copyright protection purpose, the contents can be reproduced or specially reproduced with no problem such as fast forward, and fast rewind. For special reproduction, data and key information needed therefor are made ready in advance, and using the data and the key information, the contents are specially reproduced. Alternatively, an encryption key generation rule is defined in advance for use in generation of an encryption key. By making any needed key information ready in advance from this rule, the contents can be reproduced and specially reproduced with no problem. | 12-24-2009 |
| 20100070532 | Storage device, content publishing system, and program - In order to prevent the same content from being published in duplicate, the invention provides a storage device which provides a storage area for storing content in accordance with a request from a user and can publish the stored content in which the storage area includes publishing content storage area which publishes the stored content to outside, duplication identification information for determining duplication of content is generated based on accepted content, publishing content is generated by embedding a digital watermark including identification information of the user to the accepted content if duplicate content of the accepted content is not stored in the storage area, the publishing content is stored in the publishing content storage area, and the content is not stored in the publishing content storage area if the duplicate content of the accepted content is stored in the storage area. | 03-18-2010 |
| 20100306511 | COMMUNICATION DATA PROCESSOR AND COMMUNICATION DATA PROCESSING METHOD - There is a need for providing a communication data processor easily adaptable to network configurations required for industrial Ethernet. The apparatus successively analyzes received packets. The apparatus uses a register to determine whether or not to transmit the received packet as transmission data to another port. Rewritable memory saves a program code that provides control for analyzing a reception packet and generating a transmission packet. The apparatus is capable of complying with various communication protocols by changing the program code. | 12-02-2010 |
| 20110119465 | DATA PROCESSING SYSTEM - The data processing system including: a memory block; a data-processing control block; a demultiplex-processing block; a multiplex-processing block; a decode-processing block; and an encode-processing block. In the system, the demultiplex-processing block, multiplex-processing block, decode-processing block, and encode-processing block each execute a process using memory regions in the memory block. During the execution, the data-processing control block changes a memory region to assign to the processing in response to a processing request based on results of processing which the block concerned executed in response to the preceding processing request. With the data processing system, a memory region can be used effectively even if a memory region size required for processing cannot be determined in advance. | 05-19-2011 |
| 20110154033 | ONLINE STORAGE SERVICE SYSTEM AND ITS DATA CONTROL METHOD - A WEB service providing server can execute WEB service processing using data provided by an online storage service providing server, and leaking of data at the WEB service providing server can be prevented. | 06-23-2011 |
