Abstract
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.
