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 by 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 that includes a reproduction unit for reproducing the information-stored medium and an external device for communicating with a remote server for playback permission of the information-stored medium, comprising the steps of:

(a) identifying a medium type of the information-stored medium and a data type recorded thereon, wherein the identifying step is performed by a first controller in the reproduction unit;

(b) transmitting an identified result from the first controller to a second controller in the external device, wherein a data communication path between the first controller and the second controller is established based on the identified result; and

(c) determining whether to decrypt data that is read out from the information-stored medium based on the identified result.

2. 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 identification (ID) information is recorded, and an external device for communicating with a remote server for playback permission of said information-stored medium, comprising the steps of:

(a) determining whether or not an information-stored medium is loaded onto a turn table and the type of the information-stored medium loaded;

(b) determining whether to decrypt the data that are read out from the information-stored depending on the data type, based on the determined type of information stored medium; and

determining whether a data communication path between a first controller in the reproduction unit and a second controller in the external device is established or not is controlled by the first controller, which determines if an information-stored medium is loaded and the type of the information-stored medium if it is loaded, in said reproduction unit.

3. The method according to claim 2, wherein said data communication path between said first and second controllers is not established when the determined type of the information-stored medium is loaded is an audio CD format.
