摘要:
A controller of a recording device issues a secure command to a storage device, and then waits the time estimated necessary for the storage device to execute the secure command before issuing the next secure command. When a controller of the storage device is executing the previous command, it notifies the recording device of being in process. When the previous command has been completed normally, the controller moves to the next process. Information for estimating the execution time of the command is obtained from the storage device in advance.

A portable telephone set capable of recognizing a call during music replay is disclosed. This portable telephone set comprises talking means and music replay means, and posts a call when receiving the same during music replay by the music replay means. Thus, the call can be recognized during the music replay.

An information editing apparatus is provided which can prevent a thumbnail image, which shows the contents of recorded information recorded on an information recording medium, from being accidentally changed by a misoperation of the user.The information editing apparatus includes a deciding device 8 for deciding whether a thumbnail image can be changed or not based on change permission information, which indicates whether a change can be made on the thumbnail image showing the contents of recorded information recorded on a recording medium 1. When the deciding device 8 decides that a change is not permitted, a change of the thumbnail image is prohibited.

In recording the positional information of a video frame in a program stored in a removable hard disk unit in which MPEG transport data stream is recorded, there are recorded information indicating the position in the removable hard disk unit at which the video frame is recorded; a packet identifier identifying a transport packet storing a video elementary stream of a program to which the video frame belongs; and an offset frame number indicating the offset of the video frame from the head frame in a GOP to which the video frame belongs, or offset time stamp information with reference to the head frame.

An information editing apparatus is provided which enables the user to clearly recognize the contents of recorded information which includes image information and is recorded on a recording medium. The information editing apparatus includes a first selecting device 14 for selecting a thumbnail image from images corresponding to the image information, the thumbnail image showing the contents of the recorded information recorded on a recording medium 1, a second selecting device 14 for selecting the thumbnail image from images other than the images corresponding to the image information in the recorded information, and a recording device 8 for recording first position information and second position information on the recording medium 1. The first position information indicates on the recording medium 1 the recording position of image information corresponding to the image selected by the first selecting device 14. The second position information indicates on the recording medium 1 the recording position of image information corresponding to the image selected by the second selecting device 14.
摘要:
A recording apparatus includes an MPEG encoder, and compressed data from the MPEG encoder and data of an index (a transfer rate and a necessary memory capacity for the transfer rate, or a transfer rate and a rate difference characteristic) are multiplexed and recorded on an optical disc. In a reproducing apparatus, a bit stream read from the optical disc is converted into variable bit rate data by a CD decoder and a CD-ROM decoder. The variable bit rate data is once stored in a system buffer, and then, supplied to an MPEG decoder from the system buffer. The index is extracted by a microcomputer which determines whether or not it is possible to reproduce the optical disc through comparison of the necessary memory capacity and a capacity of the system buffer. If not reproduced, the optical disc is ejected. In a case of simple reproduction, data stored in an output buffer is repeatedly outputted during a time that an operation of the MPEG decoder is suspended.

An acquiring unit receives a packet signal of a first type from the other base station apparatus. A measuring unit measures a receipt frequency of the packet signal of the first type which is received. A determining unit determines a timing for broadcasting a packet signal of a second type to inform a terminal apparatus of a presence based on the receipt frequency which is measured and a receipt timing of the packet signal of the first type which is received. A broadcasting unit broadcasts the packet signal of the second type in the determined timing. A communicating unit executes a communication with the terminal apparatus receiving the packet signal of the second type.
摘要:
An object of the present invention is to suppress fragmentation occurring due to repeated storing and deleting small capacity file data, while effectively storing large capacity real time file data. To achieve this object, according to the present invention, a block relying on a physical storage area, and a continuous plurality of the blocks, constitute a unit. The unit is set at a capacity at which real time processing is guaranteed. Image data or other such real time file data is stored with in units. Further, in a case of data processed in non-real time, the data is stored in blocks. A unit attribute table for managing the unit is arranged, and based on this unit attribute table, a determination is made as to whether or not the unit can be used at the time of storage.

A recording area of a hard disk is managed by units. Each unit comprises physically continuous recording regions having predetermined size, and usage status of the unit is stored in an allocation unit (AU) management table. Data requiring a real time processing is stored in each unit. When the usage status of the unit is changed or modified due to the recording or deletion of data, the AU management table is updated and then information indicative of the fact that the AU management table has been updated is recorded. An apparatus where the final change is made is detected at the time the hard disk is inserted or a file system is initialized. And if the apparatus which last made the change adopts the file system which does not use the AU management table, then the table is reconfigured so as to retain the consistency of the AU management table.
摘要:
In a contents data recording medium according to the present invention, a plurality of pieces of contents data are recorded as individual files. The contents data recording medium includes: link information which indicates at least positions and sizes of the contents data on the contents data recording medium; metadata which describes contents of the contents data and is used for retrieval of the individual files; and a management file which includes the link information and the metadata. By use of the management file, an access device which accesses the contents data recording medium retrieves the contents data.
