Description

  The present invention relates to a color change display system for lyric characters in communication singing by a plurality of singers. Specifically, at least two karaoke performance terminals connected by a data communication line, for example, when enjoying a duet singing, The present invention relates to a system for displaying a color change of lyrics characters at an appropriate timing in accordance with the performance of a karaoke song.

  In the currently popular karaoke system, a system capable of performing a duet singing at a karaoke performance terminal connected by a data communication line has begun to spread, and various systems for performing a communication duet singing have been disclosed ( For example, see Patent Document 1).

  The technique disclosed in Patent Document 1 connects a plurality of music performance communication devices connected to a bidirectional broadband communication network and an information management server that manages information of the music performance communication devices to exchange information. This is a technology related to a communication duet using a transmission / reception system. In other words, video / audio signals can be transmitted and received between music performance communication devices, and a search / participation means for a plurality of users to perform / participate at the same time is provided, and the performance start time and ongoing performance position are provided. Give priority to the audio signal over other video streams and feature information so that the loss rate (communication packet loss rate) and delay in communication of the synchronous signal system and the audio signal stream synchronized at the same time are not increased. A method of distributing to a communication network is used.

  In a conventional communication duet singing system, in order to perform a duet singing between karaoke performance terminals connected by a data communication line, a performance start instruction signal for karaoke music from one karaoke performance terminal to the other karaoke performance terminal. Is used to start the performance of karaoke music almost simultaneously. However, when a method of transmitting a performance start instruction signal via a data communication line is used, a data transmission delay may occur depending on the traffic state of the data communication line, and this delay is within an allowable range. If it exceeds, performance synchronization in each karaoke performance terminal cannot be achieved, and comfortable communication duet singing cannot be performed.

  Further, since the delay itself depends on the traffic of the data communication line, the delay time varies every time a communication duet is performed. In order to cope with this variation in delay time, it is necessary to adopt a method in which each karaoke performance terminal that performs communication duet singing sets the time and reserves the start of performance at an absolute time.
