摘要： A disc player, for reproducing program information from a disc on which the information is recorded as digital program information data accompanied by digital address data, comprises an optical reader for reading program information data and address data from the disc, such reader being selectively operable in a searching mode and in a playback mode, processing circuitry supplied with program information data to produce program information from the program information data, a detecting means that compares designated address data identifying desired program information with the reproduced address data in the output of the reader and system controlling means for controlling the reader to continue the searching mode until the reproduced address data match the designated address data, at which time the system controlling means operates the reader in its playback mode to read from the disc the program information data identified by the designated address data. Noise-suppressing means substantially prevents the processing circuitry from producing program information from the program information data in the output of the reader operating in the searching mode. The clicking noises and other spurious sounds produced by prior art disc players from the program information data read during the searching mode are thus prevented from occuring before the production of desired program information from the disc.

摘要： In a radio telephone system and a call charging method used in this radio telephone system, when a user of a radio telephone issues a telephone call to a public telephone network by utilizing a radio controller installed in a PBX employed on the premises of a company to which the telephone user does not belong, the PBX reports both of terminal number information of the radio telephone and call account information for charging the call account to the terminal to the public telephone network, in case that a telephone call is demanded. When the information is received, the public telephone network charges the call account to the radio telephone. If the information is not transmitted from the PBX to the public telephone network, the call account is charged to the call originating line of the PBX.

摘要： A method of error correction comprises error correction coding processing and interleaving and de-interleaving processings for digital subcoding data (as opposed to main data) in subchannels (as opposed to the main channel) to be transmitted. Apparatus is provided comprising means for performing those processings. The method comprises the steps of dividing digital subcoding data in one PACKET into a plurality of PACKs; adding a first redundant code for error detection or error correction to each of the PACKs; and interleaving the digital subcoding data in each of the PACKs and the first redundant code; whereby the interleaved data is transmitted together with frame sync signals and main data. The data in the subchannels is coded and interleaved and then recorded so that the distances between the data are maximized. Therefore, if errors should occur, the interpolation can be properly done, thereby improving the error correcting ability without requiring complicated error correction circuit or large buffer memory such as those required for the data in the main channel.

摘要： A private network system including mobile radio telephones is able to originate connection and terminate connection even when any of the mobile radio telephones are moved from one exchange where the position of the mobile radio telephone is registered to another exchange. In the private network system which comprises a plurality of exchanges for switching telephones, each of the exchanges includes one or more radio connection controllers for radio communicating with mobile radio telephones, and a plurality of mobile radio telephones connected through the radio connection controller to the exchange for switching, the radio connection controller has an area in which the controller can communicate with the mobile radio telephones. Each of the mobile radio telephones has detection means for detecting movement thereof from the area to a different area and position registration means, upon movement of the telephone to the different area, for reporting the position thereof to the home exchange through the radio connection controller, and each of the exchanges has determination means for determining whether or not a mobile radio telephone has moved from an area of radio connection controller contained in a different exchange and transfer means for transferring a terminating call to the different exchange when appropriate.
