| 20090016342 | DATA TRANSMISSION METHOD, DATA TRANSMISSION APPARATUS, DATA RECEPTION APPARATUS, AND PACKET DATA STRUCTURE - A data transmission apparatus for sequentially transmitting data in units of packets each containing transmission data to the receiving end, comprises: a reception unit for receiving the transmission data as an input signal; a packet formation unit for receiving the transmission data received, and forming an uncompressed packet in which predetermined transmission data is stored as uncompressed data, and a compressed packet in which at least a portion of transmission data that follows the predetermined transmission data is compressed and stored as compressed data; a reference information management unit for holding and managing, as reference information, information relating to the uncompressed packet formed by the packet formation unit; and a transmission unit for transmitting the respective packets formed by the packet formation unit, as a transmission signal, to the receiving end. The packet formation unit forms compressed data to be stored in a compressed packet, on the basis of the transmission data of the uncompressed packet and the reference information stored in the reference information management unit. Therefore, the number of packets to be discarded at the receiving end due to an error which has occurred in the radio section is reduced, whereby the quality of data transmitted in the transmission path including the radio section is improved. | 01-15-2009 |
| 20090052867 | Recording Device, Reproducing Device, Recording Medium, Recording Method, and LSI - A recording apparatus that generates meta-information that includes an initial address of TS packets constituting a PES packet that includes an independently-decodable picture, and size information pertaining to the picture, and records the generated meta-information in a recording medium, comprising: a detection unit operable to detect, from the TS packets constituting a transport stream, a TS packet at a head of a PES packet; a judging unit operable to judge whether the PES packet includes an independently-decodable picture; and a generation unit operable to generate meta-information that includes, as the size information, a size from a head of a PES packet that is judged as including an independently-decodable picture to a head of a succeeding PES packet. | 02-26-2009 |
| 20090070610 | DATA PROCESSOR - The present invention provides a data processor which can reduce the power consumption with the continuous compressed data, such as AV reproduction data, broadcast data or the like, to be reproduced, viewed and listened. | 03-12-2009 |
| 20090103892 | Stream Data Recording Device, Stream Data Recording/Reproducing Device, Stream Data Reproduction Device, Stream Data Editing Device, Stream Recording Method, and Stream Reproducing Method - A stream data recording device is provided for recording stream data on a recording medium. The stream data recording device includes a stream reception/analysis unit ( | 04-23-2009 |
| 20090220217 | CONTENTS REPRODUCING DEVICE - It is an object of the present invention to provide a contents reproducing device which can perform an intermittent operation with improved responsiveness to user request. The contents reproducing device according to the present invention includes: an input operation unit ( | 09-03-2009 |
| 20100208856 | Stream Data Recording Device, Stream Data Editing Device, Stream Data Reproducing Device, Stream Data Recording Method, and Stream Data Reproducing Method - When recording stream data, index information and time correction information are recorded in correspondence with the stream data. The index information specifies a position of an invalid section in the stream data. The time correction information specifies a time which, supposing that a PCR included in the invalid section was able to be got, a time clock would have shown in synchronization with the PCR. When reproducing the stream data recorded together with the time correction information and the index information, at a position where the invalid section ends, the time clock can be set to a time intended by a broadcasting system, by referencing the index information and the time correction information. | 08-19-2010 |
| 20110090999 | STREAM DATA RECORDING DEVICE, STREAM DATA EDITING DEVICE, STREAM DATA REPRODUCING DEVICE, STREAM DATA RECORDING METHOD, AND STREAM DATA REPRODUCING METHOD - When recording stream data, index information and time correction information are recorded in correspondence with the stream data. The index information specifies a position of an invalid section in the stream data. The time correction information specifies a time which, supposing that a PCR included in the invalid section was able to be got, a time clock would have shown in synchronization with the PCR. When reproducing the stream data recorded together with the time correction information and the index information, at a position where the invalid section ends, the time clock can be set to a time intended by a broadcasting system, by referencing the index information and the time correction information. | 04-21-2011 |
