Abstract: A digital communication system communicates data between a transmitter station and a receiver station by means of a carrier wave. The transmitter station has a packet assembler for assembling data having an original format into a packet, an encoder for encoding the data in the packet from an initial eight-bit form into a fourteen-bit form, and a modulator for modulating a carrier wave by the encoded data so as to transmit the packet of encoded data in the fourteen-bit form. The receiver station has a demodulator receptive of the modulated carrier wave for demodulating the same to separate therefrom the packet of encoded data, a decoder for decoding the encoded data in the packet from the fourteen-bit form into the initial eight-bit form, and a packet disassembler for disassembling the packet of decoded data to restore the original format of the data having the initial eight-bit form.

Abstract: A karaoke network system includes a central station for serving karaoke data and image data, and a group of karaoke terminals connected to the central station through a communication line having a common channel and a plurality of parallel channels for locally presenting a karaoke accompaniment and a background picture. The central station includes a first server responsive to a request command from karaoke terminal for transmitting to the common channel requested karaoke data individually addressed to the karaoke terminal, and a second server operative independently of the first server for transmitting to the parallel channels a plurality of different image data continuously broadcast to each karaoke terminal. The karaoke terminal includes an admitter for admitting the karaoke data addressed thereto from the common channel, and a selector for selecting one of the parallel channels to admit therefrom image data associated to the admitted karaoke data, such that the karaoke terminal can present the karaoke accompaniment and the background picture according to the simultaneously admitted karaoke data and the image data.

Abstract: A karaoke apparatus is provided with a first store 10 for storing a plurality of karaoke data files corresponding to a plurality of karaoke songs and containing an accompaniment data and a picture index data, a second store 2 for storing a plurality of primary pictures, and a third store 3 for storing a plurality of secondary pictures which are mixed to the primary pictures. Upon requesting a desired karaoke song to select the corresponding karaoke data file, particular ones of the primary pictures and the secondary pictures are retrieved from the second and third stores according to the picture index data contained in the selected karaoke data file. A video mixer 34 mixes the retrieved secondary picture to the retrieved primary picture to synthesize a composite picture which meets a mood of the requested karaoke song. A tone generator operates according to the accompaniment data contained in the selected karaoke data file to sound an instrumental accompaniment of the requested karaoke song. A monitor 4 displays the composite picture in synchronization with the instrumental accompaniment so as to present a background screen of the performed karaoke song.

Abstract: A karaoke network system is composed of a central station (20) for serving karaoke data and image data, and a group of karaoke terminals (30) connected to the central station through a communication line (10) (e.g. a LAN) having a common channel and a multiple of parallel channels for locally presenting a karaoke accompaniment and a background picture. The central station includes a first server (22) responsive to a request command from a karaoke terminal for transmitting to the common channel a requested karaoke data individually addressed to the karaoke terminal, and a second server (21) operative independently from the first server for transmitting to the parallel channels a plurality of different image data continuously broadcasted to each karaoke terminal. The karaoke terminal includes a selector (34) for selecting one of the parallel channels to admit therefrom image data associated to the karaoke data admitted from the common channel by an admitter (31).
