摘要:
Timer generates a first time code with a relatively high resolution. Second time code, given from a reproduction device in relation to video or music reproduced by the reproduction device, has a resolution lower than the first time code. By correcting the timer-generated first time code on the basis of the second time code, there can be generated a corrected first time code having a same over-time progression as the second time code but having a higher resolution than the second time code. Once an operator, such as a mixer, is operated at given reproduction timing of the video or music during recording, data indicative of the operation is stored in a memory along with the first time code corrected in accordance with the second time code. In reproduction, the memory is read in accordance with the first time code, corrected on the basis of the second time code.

Each track is made up of a linkage of regions, and each of the regions is made up of a linkage of nodes or clusters. Sound data are stored on a cluster-by-cluster basis, and reproduced by tracing such linkages. Each time editing is performed on a virtual track of the track, a track data of a corresponding leading region in the edited virtual track is stored in memory as a history record of the track. When an undoing instruction is given, desired record data is selected from the history records of the leading region. Where the sound data in the trailing-end cluster of a preceding region and leading-end cluster of a succeeding region amount to less than 50% of a predetermined total data quantity of sound data to be contained in a proper cluster, the sound data represented by a trailing-end offset and the sound data represented by a leading-end offset are combined together and then written into a reproducing cluster. In reproduction, the sound data written in the reproducing cluster are reproduced for a connecting portion between the preceding and succeeding regions.

A mobile communication service control system according to the present invention has a home location register 13 storing subscriber information, a switching unit 12 for sending a subscriber information inquiry signal 201 to the register 13, and a service control unit 14 for controlling a service provided for subscribers. The home location register 13 stores service information 309 necessary for a start of control of the service at the service control unit 14 and sends the service information 309 along with a response signal 308 to the subscriber information inquiry signal 201 to the switching unit 12. The switching unit 12 transfers the service information 309 received from the register 13, to the service control unit 14.
摘要:
A record and reproduction controlling device is connected to a hard disk memory via a bus. This controlling device receives from a computer information necessary for read/write operation, on the basis of which the controlling device performs its own process to write to or read from the hard disk. The record and reproduction controlling device temporarily stores tone data read out from the hard disk memory into a first buffer memory and then transfers the tone data from the first buffer memory to a second buffer memory. The tone data thus stored in the second memory is then read out at a predetermined readout rate to reproduce a musical sound. It is possible to select either a first reproduction mode for reproducing a data file having tone data of plural channels recorded in an interleaved state, or a second reproduction mode for permitting a simultaneous reproduction of plural data files each having not-interleaved tone data recorded therein. The controlling device controls the tone data transfer from the first buffer memory to the second buffer memory depending on which of the reproduction modes is employed.

A communication restriction is performed in an appropriate manner for a mobile station (subscriber) that has roamed out of a communication operator's network where subscriber information is registered into another one. In a roaming system including an HLR 110 and a GGSN 120 of a first communication operator's communication network 100 and an SGSN 220 of a second communication operator's communication network 200, the SGSN 220 receives a packet transmission request from a mobile station 210 and transfers it to the GGSN 120. The GGSN 120 that has received the transferred packet transmission request makes an inquiry about subscriber information of the mobile station 210 to the HLR 110. The HLR 110 identifies whether or not the packet transmission request is to be subject to a restriction, and returns an identification result to the GGSN 120 when it is to be subject to the restriction. The GGSN 120 transfers a response to the identification result to the SGSN 220. The SGSN that has received the transfer transfers the response to the identification result to the mobile station 210.

There are provided a mixing apparatus that enables a user who is mixing and the like to be positively engaged in the performance of a musical composition at a low cost by simple operations, a method of controlling the same, and a mixing control program. A plurality of first audio data are input, and the input plurality of first audio data are mixed. A storage device stores a plurality of second audio data. A plurality of operating members are each disposed to be depressed and have a sensor for detecting the depression. At least one of the plurality of second audio data stored in the storage device is assigned, respectively, to at least one of the plurality of operating members. The second audio data is reproduced when the at least one of the plurality of operating members to which the second audio data is assigned is detected as being depressed. The second audio data reproduced by the reproducing device is input, and the input second audio data and the input first audio data are mixed.

摘要:
Even if the number of subscribers increases, such increased number of the subscribers can be handled by a mobile communication system without increasing the equipment of the system, so that the assignment of the radio resources should not be constrained due to excessive location registration. A MSC of a mobile communication system determines a location registration period for each of mobile terminals according to subscriber information retained by HLR or VLR. In this case, a relatively long location registration period is set for the mobile terminal incorporated into a vending machine and having a weak mobility, as compared to the mobile terminal that frequently moves. This eliminates the wasteful operation of performing the location registration in a uniform period with the mobile terminal that frequently moves, so as to avoid the situation in which the assignment of the radio resources are constrained.

摘要:
In a waveform data processing apparatus, a transfer section reads out waveform data of multiple tracks stored in a first storage device in data units, and transfers the read waveform data to a second storage device having an access speed higher than an access speed of the first storage device. A reproduction section reads out the waveform data of the tracks from the second storage device for every sampling period, and which reproduces an audio signal according to the read waveform data. A control section replaces old waveform data which has been read from the second storage device by new waveform data which is read from the first storage device, whereby the audio signals of the tracks are continuously reproduced. The control section controls the transfer section to transfer, from the first storage device to track regions provided in the second storage device for respective tracks, pieces of the waveform data corresponding to the respective track regions, in an order of the tracks having a smaller number samples of non-reproduced waveform data or in an order of the tracks having a smaller number units of non-reproduced waveform data.
