A processing unit performs a method including controlling a reading-out of data from a first storage medium at a predetermined read-out data rate to produce inputted data, and controlling a compression of the inputted data to produce first compressed data of a first compressed format. The method includes controlling a storage of the first compressed data in a second storage medium at a faster writing data rate than the predetermined read-out data rate, controlling a reading-out of second compressed data of a second compressed format from the second storage medium, and controlling a decompression of the second compressed data to produce decompressed data. The method also includes controlling simultaneously the storage of the first compressed data in the second storage medium, the reading-out of the second compressed data from the second storage medium, and audibly reproducing the decompressed data. The first compressed format is different from the second compressed format.

Data processing system having data reproduction independent of data processing

The present invention provides screen displaying technology allowing improvement in operability and convenience for the user. A screen display apparatus receives a content, displays a plurality of tabs in a display screen, corresponds content information to any one of the plurality of tabs, and displays the content information corresponding to a displaying tab. In the case of corresponding content information to a non-displaying tab other than the displaying tab, it is determined whether or not a there is a non-corresponded, non-displaying tab to which other content information is not corresponded, and when the non-corresponded, non-displaying tab does not exist, the non-displaying tab selected based on a predetermined selection condition and the content information are corresponded. Furthermore, the screen display apparatus calculates a progress status of at least one or more of receiving a content, generating a content image by drawing the content, and storing the content image in an image storage means, and then outputs the calculated progress status associated it with a tab corresponded to the content.

System and method for corresponding tabs to content information

A device with a display is provided with a first touch pad on the front face of the device and a second touch pad on the rear face. When an operation is performed only on the first touch pad, the process allocated to the point of contact or the pattern of movement thereof is identified and executed. When both the first and second touch pads are used for operation, the process defined to correspond to a combination of modes of movement of the points of contact is identified and executed. When an operation is performed only on the second touch pad, only the component of the movement of the point of contact in a limited direction is extracted to calculate the amount of scrolling, and a scroll process is performed accordingly.

Information processing device adapted to receiving an input for user control using a touch pad and information processing method thereof

An information-processing apparatus includes a processing unit that compresses inputted data to produce compressed data of a first compressed format. The information-processing apparatus also includes a storage unit that stores the compressed data in a storage medium. The processing unit decompresses data, stored in the storage medium, of a second compressed format to produce decompressed data. Further, the processing unit controls the storage unit to store the compressed data of the first compressed format in the storage medium while the processing unit simultaneously decompresses the data, stored in the storage medium, of the second compressed format and reproduces the decompressed data. The first compressed format is different than the second compressed format.

This invention relates to a terminal device capable of communicating with an accounting center, an accounting system, and a data processing method. A point memoryof a recording/reproducing devicestores accounting point information. An HDDstores information distributed from an external source. A CPUupdates the accounting point information stored in the point memoryand updates attributes of the distributed information when the distributed information is stored onto the HDD. Thus, such inconvenience that communication with a distribution/accounting centeris carried out every time information is distributed to the recording/reproducing deviceis avoided.

Terminal device, accounting system and data processing method

High-rate writing of data recorded on a CD into a hard disk drive (HDD) is performed while reproducing data read out of the CD at the standard bit rate prescribed for the CD. PCM data corresponding to a playback time of 10 seconds, for example, is read out of a CD and stored in a memory. The data is read out of the memory at appropriate timing and outputted after being converted into an analog audio signal by a D/A converter. In parallel, data for writing is read out of the CD in succession to reading of the data for playback and stored in the memory. The data read out of the memory is coded and compressed by an encoder and then stored in the memory. The compressed data is read out of the memory in units of a certain amount suitable for writing in an HDD and then written in the HDD. When the data stored in the memory for playback has become smaller than a predetermined amount, an interrupt is generated during the writing process with the processing, which is given top priority, so that a next set of playback data is read out of the CD and stored in the memory.

PCM data corresponding to a playback time of 10 seconds, for example, is read out of a CD and stored in a memory for subsequent read out. In parallel, data for writing is read out of the CD and stored in the memory. The data read out of the memory is coded and compressed by an encoder and then stored back in the memory. When the data stored in the memory for playback has become smaller than a predetermined amount, an interrupt is generated during the writing process with the processing, which is given top priority, so that a next set of playback data is read out of the CD and stored in the memory.

Although music program data has been recorded on a disc, imperfect index data or a signal has been recorded so that music program data is prohibited from being reproduced. To allow music program data to be reproduced, the index data is rewritten to perfect index data or a permission signal that allows music program data to be reproduced is transmitted through a communication line. Thus, music program data can be reproduced from the disc. Since music program data is not directly transmitted, the data transmission time is shortened. The music program data can be downloaded at high speed. In addition, the charging process can be smoothly performed. Moreover, music program data can be prevented from being illegally used.
