Abstract

The present invention relates to a reproducing apparatus-for a remote rental system, and in particular to a reproducing apparatus and control method for the apparatus bus which the playback permission of the video title, advertisements, and charge collection are performed remotely over a public communication network between a remote server and a reproducing apparatus. The remote rental system of the present invention comprises an information-stored medium with a unique ID code, a reproducing apparatus for playing the data on the information-stored medium, and a remote server for controlling the playback of the information-stored medium on the reproducing apparatus over the communication network. The remote rental system enables customers to keep the information-stored medium at a low cost without return, to use the information-stored medium whenever they want, and to receive useful information such as public advertisements that are provided continually over the communication network.

Claims

1. A method for controlling remote reproduction of an information-stored medium in a reproduction apparatus that includes a reproduction unit for reproducing the information-stored medium in which an ID information is recorded and an external device for communicating with a remote server for playback permission of the information-stored medium and for decrypting the data that are read out from the information-stored medium after receiving playback permission from the remote server, comprising the steps of:

clearing the data that remain in a memory of one of the reproduction unit and external device that receives a signal to inquire about data acceptability from the other of the reproduction unit and external device, so as to prevent the received data from being conflicted with the data remaining in the memory when said reproduction unit and said external device transmit data to each other; and

transmitting an inquiry signal notifying the permission of the data transmission to one of the reproduction unit and external device after the memory clearing operation, and

wherein the step of clearing the memory comprises the sub-steps of;

transmitting an inquiry signal to said external device to examine if the transmission of the data which are stored in the memory of said reproduction unit after they are read out from the information-stored medium is acceptable to said external device; and

clearing the data that remain temporarily for decryption in the memory of said external device when a data transmission check signal is received, to prevent the data transmitted from the memory of said reproduction unit from being conflicted with the data in the memory of said external device.

2. The method according to claim 1, further comprising:

controlling the operation of the production unit using a first controller; and

controlling the operation of the external device using a second controller.
