Title: Multiplexing procedures
Inventor: KANAMARU HITOSHI
IPC: G11B20/06
Filed: 1983-10-28
Abstract: A method for recording and reproducing multiplex information in which two subcarriers of the same frequency are modulated by two respective subchannel signals. The modulated signals are added to two main channel signals to produce two corresponding sum signals. Two main carriers of different frequencies are then modulated with the two sum signals. Information is recorded on a storage medium in response to the frequency-modulated signals. For reproduction of the recorded information, the main carriers are extracted and separated in frequency, and then detected by separate frequency detecting means. A selected one of two detected outputs from the frequency detecting means is supplied at a time to a common subchannel demodulating means. Also disclosed is a multiplexing method comprising adding subcarriers signals modulated by first and second channel signals and modulating a main carrier with the added subcarrier signals. A further multiplexing method disclosed involves modulating a subcarrier having a frequency three times that of a horizontal synchronising frequency with a subchannel signal, adding this modulated signal to a main channel signal to produce a sum signal, offsetting in frequency a main carrier by a frequency of one quarter that of the horizontal synchronising signal frequency and frequency modulating this offset main carrier with the sum signal. Finally, a recording method is disclosed comprising controlling the level of a subcarrier in dependence upon a recording program mode signal, modulating the subcarrier with a subchannel signal, adding the modulated signal to a main channel signal to produce a sum signal, frequency modulating a main carrier with the sum signal and recording the f.m. signal, and identifying the program mode by detecting the subcarrier level.

Title: Messaging apparatus
Inventor: WILSON JEFF
IPC: H04M3/533
Filed: 1988-11-14
Abstract: The apparatus overcomes the problem of communication where two people wishing to communicate by telephone are not able to answer their calls, and where at least one of these people does not have a voice messaging apparatus. In response to a received message the apparatus allocates a temporary mailbox, that is a storage location, to enable any reply to a message to be left. The apparatus provides the caller with an address such as a telephone number and/or password to enable the caller to access that storage location at a later time. When the user of the messaging apparatus retrieves the initial message he is alerted by the apparatus to the fact that a storage location has been allocated to the caller. The user can then respond by recording a reply to the initial message in the allocated storage location. The subsequent access by the original caller of that location enables the caller to hear the reply. The apparatus may be located at a central station or with the user.
