  • Patent number: 5453570
    Abstract: Disclosed is a karaoke authoring apparatus for mixing or authoring karaoke music data based on an electronic music sound source. The invention can analyze chronologically, in a sound reproduction block, the musical performance data expressed by a code such as MIDI code and has a pre-inserted event code, and will generate an interrupt in a timer circuit at a time interval based on the tempo instruction on the code. The invention can also acquire, as an individual file at the timing of the event code, an integrated value given by the timer circuit in accordance with the type of event, and combine and arrange these files in chronological order to calculate a time difference between consecutive event codes, for producing time data. The authored data allows color turning of the words of the music, page turning, presentation of the title of the music and a video image update which is performed accurately to the timing as planned, in synchronism with the musical performance.

  • Patent number: 5268904
    Abstract: In a method for controlling ISDN terminals connected to a passive bus conforming to an ISDN basic interface, the ISDN terminals being coupled to each other via a network, there are provided the following steps. A first step is to manage status of use of information channels in the passive bus by means of a communication server connected to the network. A second step is to send the communication server command data showing that the ISDN terminals will use the communication channels. A third step is to update management data showing the status of use of the information channels managed by the first step in response to receipt of the command data. A fourth step is to send updated management data showing the status of use of the information channels obtained after the command data is received to the ISDN terminals via the network.
