    • A karaoke online system distributes karaoke data blocks having identification codes from a center station to a plurality of karaoke terminals through a broadcast network. In the center station, a transmitter broadcasts the karaoke data blocks with the identification codes to the broadcast network. In the karaoke terminal, a receiver receives the karaoke data blocks with the identification codes from the center station through the broadcast network. A buffer memory temporarily memorizes each of the karaoke data blocks received by the receiver. A storage device stores the karaoke data blocks after each of the karaoke data blocks is temporarily memorized in the buffer memory. A controller discriminates the karaoke data blocks while each of the karaoke data blocks stays in the buffer memory according to the identification codes attached to the karaoke data blocks for judging as to whether each of the karaoke data blocks should be transferred from the buffer memory to the storage device. The controller further operates when judging that the karaoke data block should be transferred for driving the storage device to store the karaoke data block.
    • 卡拉OK在线系统通过广播网络将具有来自中心站的识别码的卡拉OK数据块分配给多个卡拉OK终端。 在中心站,发射机将具有识别码的卡拉OK数据块广播到广播网络。 在卡拉OK终端中,接收机通过广播网络从中心站接收具有识别码的卡拉OK数据块。 缓冲存储器临时存储由接收器接收的每个卡拉OK数据块。 在每个卡拉OK数据块被暂时存储在缓冲存储器中之后,存储装置存储卡拉OK数据块。 控制器在卡拉OK数据块中的每一个根据附加到卡拉OK数据块的识别码停留在缓冲存储器中时判别卡拉OK数据块,以便判断卡拉OK数据块是否应该从缓冲存储器传送到 储存设备。 当判断卡拉OK数据块应被传送以驱动存储设备以存储卡拉OK数据块时,控制器进一步操作。
