A recorder according to the present invention is designed to record data files, including video data and/or audio data, on a storage medium. The recorder includes: a status detecting section for determining whether or not the recorder is in a non-recording status in which the recorder is performing no recording operations; and a processing section for performing, as soon as the non-recording status is detected, processing to get ready to transmit at least one data file, which was recorded on the storage medium at or after a predetermined reference time, toward a server and generating at least one data file to transmit. The processing section performs at least one of format conversion processing and aggregation processing of aggregating multiple data files together.

Recorder

In jumping reproduction, when an MPEG transport stream processed by the jumping reproduction is decoded and displayed, many noises occur in the video and the audio corresponding to the vicinity of the jumping. Provided are: a hard disk sectionof reading and reproducing AV data recorded as an MPEG transport stream in a recording medium; and an AV transfer control blockof controlling the hard disk sectionin such a manner that during the reproduction of the AV data, when the reproduction is performed with skipping a predetermined portion of the AV data, before the skipping of the predetermined portion, transport packets are outputted up to the last one among those constituting a frame, and that after the skipping of the predetermined portion, transport packets are outputted starting from the beginning transport packet of the next I frame.

A recorder to write content data on a storage medium and includes: a determining section, which receives incoming content data and determines data properties thereof; a selecting section for selecting, depending on whether a predetermined condition is satisfied, either a first type of write processing to add the data to an existent file on the storage medium or a second type of write processing to write the data as a new file; and a writing section for writing the data on the storage medium by performing the selected type of write processing. The selecting section selects the first type of write processing if at least one part of the data properties of the data that have been determined by the determining section is identical with those of the data that is stored in the existent file on the storage medium but selects the second type of write processing unless this condition is satisfied.

Recording device for writing content data without continuity in presentation timing

Continuous transfer of AV data without a break necessitates to perform replacement processing of a disk access unit and takes labor and time. A characteristic is that an HDD is disposed which writes AV data in a recording medium, that an AV recording/reproducing controller is disposed which, when there is a write error in writing of AV data in a disk access unit which is a minimum unit for continuously accessing the recording medium, controls the HDD such that this disk access unit will be skipped and said AV data will be written in the next disk access unit, that skip processing judging means is disposed, and that a replacement area is not formed in the recording medium.

Alternation processes reduce the recording and reproducing speed of a hard disk apparatus. A hard disk apparatus comprising: an HDDfor recording AV data onto a hard disk; and stream controlling meanswhich is connected to the HDDand thereby processes the signal of AV data transmitted from an IEEE1394 I/F 7 or the signal of AV data transmitted to the IEEE1394 I/F 7; whereby the hard disk apparatus can record and/or reproduce the AV data, wherein when AV data transfer is not normally completed for a disk access unit which is a minimum continuous unit in the access to the hard disk, an alternation process on a disk access unit basis is carried out so that another disk access unit is used hereafter in place of that disk access unit.

Hard disk apparatus, medium, and collection of information

A reproducing device has an input means for inputting an MPEG transport stream from a hard disk; and reproducing means for reproducing the inputted MPEG transport stream, in case of reproducing a special reproduction image, the input means extracts an MPEG transport stream from an arbitrary position to another arbitrary position in the inputted MPEG transport stream to output the special reproduction image used for special reproduction, and the reproducing means reproduces the special reproduction image while detecting whether a plurality of pieces of picture data exist in one of MPEG transport packets constituting the outputted special reproduction image.

There is a PSI receipt waiting time of two seconds or so from a start of decoding of an MPEG transport stream to actual display of AV data. There are provided first means of recordingfor recording a predetermined signal discretely including additional information of a program; means of controlling recordsfor having said predetermined signal recorded by first means of recording; means of controlling reproductionfor having said predetermined signal reproduced from said first means of recording; means of detecting PSIfor detecting program specific information (PSI) from said predetermined signal; and means of adding PSIfor adding said PSI to said predetermined signal.

A signal transmission system includes a transmitter and a receiver connected via a transmission line. When a control circuitin the transmitteroutputs a test signal to a transmission line, a voltage detection sectionin the receiverdetermines whether a voltage value on a terminalfalls within a given range or not. Based on the result, the control signal generation sectiongenerates an instruction as to whether or not to change the current amount of the driving current. The control circuitin the transmitterdrives the transmission linewith the driving current increased or decreased based on the instruction, and again outputs a test signal. This process is repeated until the voltage on the terminalof the receivercomes into the range. As a result, an optimum output impedance for the control circuitof the transmittercan be obtained. When transmitting a signal via the line, matching is dynamically established between the output impedance of the driving circuit and that of the line, whereby a fast signal transmission can be realized.

Device and method for matching output impedance in signal transmission system

A special reproduction data generating device is provided. An MPEG transport stream is input to the special reproduction data generating device. The device includes a special reproduction data generator for directly generating special reproduction data by selecting a transport packet including data of a predetermined kind of frame from transport packets of the MPEG transport stream, without converting the inputted MPEG transport stream to an ES (elementary stream) or PES (packetized elementary stream). The special reproduction data generating device outputs the special reproduction data as an MPEG transport stream.
