摘要:
In a compact disk player, a demodulator (2) demodulates signals picked up from a disk, an error detection circuit (8) corrects the demodulated data, and an interpolation circuit (10, 12, 14, 16) interpolates output data from the error detection correction circuit according to a result of the error correction. A level setting circuit (10, 12, 16) sets to zero the level of data which has not been error corrected in a peak search, according to the error correction result, and a peak level detection circuit (20, 22, 24, 26) detects a peak level of digital audio signals outputted by the level setting circuit.

In the source of the page “A Company—the Page for Selling CDS”, the number of characters of the bookmark title information is limited to 21 characters. Thus, even if the size of the bookmark display area AR2 is not large, the client terminal 2 can display all of the bookmark title information “A Company's CD Sales Page” on the bookmark display area AR2, since this bookmark title information, an abbreviation of the page title information “A Company—the Page for Selling CDs”, consists of 21 characters.

The present invention is directed to a disc reproducing apparatus in which a signal recorded on a disc is optically read out from the disc and reproduced as an audio signal. This disc reproducing apparatus includes a memory in which digital data is stored temporarily, a controller for controlling write and read of the memory such that the digital data is intermittently written in the memory at the first transfer rate and the digital data is continuously read out from the memory at a second transfer rate lower than the first transfer rate and a display device for displaying an amount of the digital data stored in the memory so that an increase or decrease of the amount of the digital data can be visually confirmed. Further, the present invention is directed to a disc recording apparatus in which an input digital audio signal is encoded and recorded on a disc. This disc recording apparatus includes a memory in which compressed data is temporarily stored. A controller for controlling the memory such that the compressed data is continuously written in the memory and the compressed data stored in the memory is intermittently read out from the memory at every predetermined data amount, and a display device for displaying a storage amount of the compressed data stored in the memory so that an increase or decrease of the amount of the compressed data can be visually confirmed.

A reproducing apparatus and method is provided. The reproducing apparatus includes a detection device, a list preparation device, and a reproduction device. The detection device is configured to detect acquisition of first page information. The list preparation device is configured to prepare a list of content identification information collected at least from the first page information and from second page information linked from the first page information when the detection device detects the acquisition of the first page information, the content identification information being such as to indicate where streaming content data is availably located. The reproduction device is configured to reproduce the streaming content data upon acquisition, the streaming content data corresponding to the content identification information in the list prepared by the list preparation device.
摘要:
The present invention carried out editing of a management region of a recording medium by carrying out an automatic erase operation as a result of simply designating the start point and end point of the section to be deleted and linking the programs preceding and proceeding the erased portion while carrying out a prescribed section delete function for erasing unnecessary portions of prescribed periods of data recorded on the recording medium. This therefore provides superior delete position designation because the position of the start and end points of the section to be deleted can be adjusted.
摘要:
A method and apparatus for recording control for a recording medium having a data recording region for recording data such as audio data, speech data, and a control data region for recording control data for the data recording region. The method and apparatus includes identifying a non-silent recorded portion and a silent recorded portion of the data recorded in the data recording region based upon the signal level of the data recorded in the data recording region, and recording control data for separating the data recorded in the data recording region into temporally former and temporally latter portions at a boundary portion between the non-silent recorded portion and the silent recorded portion based upon the results of the identification after recording of the data in the data recording region has ended.
摘要:
A disc recording apparatus which uses a disc recorded with address data beforehand and writes the TOC (information about recorded data) in a predetermined area on the disc. When a predetermined key is operated during recording, an address on the disc corresponding to an operation point of the key is written to the predetermined area as the TOC, generating positional information for data retrieval which substantially has no offset from a marker point on the disc. In reproduction, the TOC is read before starting reproduction, so that a desired marker point can be detected promptly based on the positional information of the TOC data.

摘要:
A recording and reproducing apparatus corresponding to a recording medium having management information (U-TOC) for managing the order of reproduction and reproducing operations for recorded data (pieces of music), having a controller which makes it possible to rewrite the management information when the order of the data is specified by a program so that the order of reproduction is changed in accordance with the order of data specified by the program on the recording medium (F110) or to rewrite the management data so that the data specified by the program become erased data (F106), allowing the erasure of plural pieces of music and the changing of the order of reproduction to be carried out easily.
摘要:
A digital signal with included sub-code data reproduced from a first recording medium is recorded to a second recording medium having a data recording area and a table of contents (TOC) area establishing an end point of the digital signal outputted from the first recording medium by detecting if a reproducing time information of the sub-code data outputted from the first recording medium with the diginal signal ceases changing, detecting whether an audio data is included in the digital signal outputted from the first recording medium, and if not, pausing the recording operation for a predetermined time period, and after the predetermined time period passes, if it is detected that the reproducing time information ceases changing and the audio data is still not included in the digital signal outputted from the first recording medium, the recording operation of data in the second recording medium terminates, and a data indicative of a recording end point of the data which is recorded in the data recording area of the second recording medium is recorded in the TOC area of the second recording medium, the recording end point being a time point at which a predetermined time period passes after it is detected that the reproducing time information ceases changing and the reproduction of the first recording medium terminates, and then the whole recording operation to the second recording medium terminates.
