Abstract

When the terminal 5 requests a partial access of a desired karaoke song to the center 3 in S380, only the climactic passage data of the karaoke song is transmitted from the center 3 to the terminal 5. The terminal 5 reproduces the climactic passage in S400. Then, the terminal 5 determines whether or not the user will pay for the karaoke song in S410. When the payment is confirmed, the terminal 5 requests total access to the center 3 in S340, receives the entire data of the karaoke song in S350, and reproduces the data in S360. It is possible to prevent the user from erroneously requesting a total access of a karaoke song which the user does not want to sing. It is ensured that the user can obtain karaoke songs which he/she really wants to sing, within a short period of time.

Dependent claims

A data transmission device for transmitting a desired information via a transmission line from a central control unit to a plurality of terminals, the data transmission device comprising:

a central control unit including data memory means for storing information data, including image information, sound information, or both, in separate plural data units and in separate plural partial access data, at least a part of each partial access data being the same as a part of a corresponding data unit so as to indicate the content of the information data of the corresponding data unit;
and
a plurality of terminals connected to said central control unit via a transmission line so that the information data can be transmitted from the central control unit to the plurality of terminals, each of the plurality of terminals including:
data selection means for selecting a desired information data of at least one data unit out of the information data stored in the memory means in the central control unit;
partial access request means for requesting partial access of the information data selected by the data selection means;
total access request means for requesting total access of the information data selected by the data selection means;
and
output means for, based on the information data transmitted from the central control unit, reproducing and outputting image information, sound information, or both from the partial access data in response to the partial access request performed by the partial access request means and from the entire part of the data unit in response to the total access request performed by the total access request means, wherein each partial access data is included in a corresponding data unit as a predetermined portion of the corresponding data unit that indicates the content of the information data of the corresponding data unit.
