The invention prevents unauthorized use of data in communications. When terminals with different data transmission rates are simultaneously connected to a host computer, the host computer sets a single common data communication rate to all the terminals to assure synchronization. The host computer is connected each terminal via communications network. The host computer sends a data body to each terminal over a unidirectional communications link in a cyclic manner while a bidirectional communications link is established between the host computer and each terminal. Response to an individual request from each terminal, the host computer downloads descrambling data for descrambling and a loader program for executing the data body. The host computer determines from among the terminals, any terminal having a communications means that sets the lowest data transmission rate, and sets the data transmission rates of the terminals simultaneously connected thereto to the lowest rate.

The center includes a data base for storing a plurality of items of compound data, each item consisting of a specified number of interrelated data groups, and a transmission unit which accesses the database, reads data groups in order from an item of compound data, converts the resultant digital signals to analog form and outputs the analog signals to the telephone line. The user's home includes a receiver, which converts analog signals received from the telephone line to digital form, and when the specified number of data groups have all been input, outputs each of the data groups simultaneously, and a specified number of terminals which operate in accordance with the data groups received from the receiver.

Device for the transmission of data by telephone line

The invention converts information input from either a charge line or a non-charge line to data form and then stores it in a memory device along with identification data specifying the type of line on which the information was received. It also reads information from the memory device in response to information read requests received by way either of a charge line or of a non-charge line and, when called upon to output said information either to a charge line or to a non-charge line, it inhibits the output of the information to a non-charge line in cases where the line indicated by the aforementioned identification data and the line on which the information read request is received are both non-charge lines. This enables either the sending party or the receiving party of a service, but not both, to be charged for the service while at the same time ensuring that, if the sending party and the receiving party of the service both use a non-charge line, the output of the information will be inhibited in order to preserve the integrity of the charging function. Moreover, if the line indicated by the identification data and the line on which the read request is received are both charge lines, a message is sent to the issuer of the read request to indicate the availability of a non-charge line. This prevents the sending party and the receiving party of the same service from both being charged for the service.

A karaoke system incorporating a backing chorus mixing device having a memory for storing backing chorus patterns converted to data form by breaking down and organizing the backing chorus for a particular piece of music into appropriate segments. Thus, when reproducing a piece of music created in accordance with the MIDI standard, all the chorus data corresponding to said piece of music can be read from said memory and synchronized with the music reproduction data, after which appropriate chorus patterns can be selected one by one and mixed into the music. The invention thus enables the requisite memory capacity to be kept to a minimum while at the same time enabling not only the reproduction of original sounds from music data created in accordance with the MIDI standard but also the reproduction of a mutual backing chorus sound created from data based not on the MIDI standard but obtained directly from natural human voices.

The invention relates to a technique whereby karaoke music and lyrics, which have been digitalized with the help of MIDI data, are transmitted by public telephone line for reproduction on a terminal unit. Associated dynamic images are, on account of the volume of data required, stored independently of the music and lyric data within the terminal unit itself and retrieved and extracted with the help of codes which are written into the data in advance. The dynamic images and the lyrics are finally mixed and output to a visual display medium.

Karaoke music reproduction device

The invention provides an indication for a karaoke singer of that music in the karaoke music library which would be best suited to the singer's own vocal characteristics. For the purpose of providing this indication, the singer's voice signals are first of all sampled at suitable intervals and the sample waveforms converted into specimens made up of digital values. A body of data relating to vocal characteristics is at the same time stored in the device, each item of said data being assigned its own code. When the above specimens are input, they are compared with the stored data by an evaluation means which then identifies the items of data that resemble each other most closely. The codes which are incorporated into the data items so identified are then treated as retrieval items and any library data with a matching code for each of a plurality of pieces of music is duly retrieved and the music with the matching code is extracted.

Karaoke music selection device

The invention is designed to provide a clear indication, for karaoke purposes, of the point at which a piece of music starts to build to a climax. To this end, the invention first relates warning period data, which is inserted in advance of the climax start position, to the music data and stores it in memory. This warning period data is subsequently read out and matched with the music data for input to a counter, which initiates a count immediately on receipt. At the same time, the warning period is divided into equal warning time intervals, the countdown of which provides a basis for the output of a message advising the user of how long remains before the climax start position.

Musical climax display device

The invention, which assumes the use of digital music data, such as MIDI data, inserts marker codes in advance into music data at appropriate break points such that the music can then be replayed in accordance with said marker codes without sounding unnatural to the listener. If, while an output means is reading music data out of a memory means and outputting it to a sound source, the user decides he wants to replay a part of the music, he inputs a position specification by way of an operation means. A replay means then issues a replay instruction to said output means which returns to a point close to a stored marker code and outputs the music data from that point onwards. The prior insertion of marker codes into the music data at appropriate break points enables the music to be replayed from any point without arousing a feeling of unnaturalness in the listener. Moreover, by restarting the music during a replay from the point specified by the marker code immediately prior to the marker code stored in the operation means, it is possible to make allowance for a user's slowness in inputting the replay position specification into the replay means.
