  • One embodiment of the system enables a computer user on a high speed network to play a CD ROM title as if the user were using the CD ROM into the user's local machine.
  • a server remotely located from the user's machine, stores images of CD ROM titles on a hard disk or hard disks.
  • the user's computer is the client, and has a software program that emulates a CD ROM driver.
  • the software program then communicates to the remotely located server through a computer network to obtain data from the CD ROM images.
  • the computer program located on the user's machine thus emulates a CD ROM driver to the operating system or the application.
  • the user may be able to use the title as if the title were loaded from a CD ROM drive coupled locally to the user's machine.
  • the computer network is an IP network, and the computer program that emulates the CD ROM driver communicates to the server through TCP/IP.
  • the user first visits a web site.
  • the web site may, according to one embodiment of the invention, be the same server on which images of the CD ROM titles are stored. According to another embodiment of the invention, the web site is a different server from the server on which the images of the CD ROM titles are stored.
  • Software associated with the web site determines the identity of the user and performs authentication. A password may be required and other account information may be verified or obtained. Payment may be required and/or obtained.
  • images of CD ROMs are stored in various servers. The software associated with the web site determines which server from which the user should obtain access to the CD ROM the user desires, based on the identity and location of the user.
  • the user's computer system includes a browser with a plug-in, which provides access to the web site and server containing images of the CD ROMs.
  • the plug-in is given enough information to tell the user's software program that emulates a device driver to which server it should connect and which image it should load.
  • the software that emulates the driver emulates a CD ROM driver with the selected remotely located CD ROM image.
  • the user can play the CD ROM title as originally intended by the CD ROM's manufacturer.
  • a CD ROM title may require a particular communications bandwidth.
  • the system may selectively download onto the user's computer part or all of the CD ROM title the user wishes to play. If the bandwidth is not sufficient to emulate local play of the title, then a portion or all of the image of the CD ROM is downloaded to a storage device, such as a hard drive, locally coupled to the user's computer. Then, when the user plays the title, it may run at the proper speed. For copy protection or usage tracking, an active connection may still be required between the server and the user's computer in order to allow for play of the title. Additionally, as the title is emulated via communication between the server and the device that emulates a CD ROM driver, data from the image may be stored on a storage device locally coupled to the user's computer.
  • Such data may include graphics, computer code, or other data.
  • this data is later again needed by the title application running on the user's machine, it is accessed from the local storage device rather than the remote server in order to preserve bandwidth and the communication between the user's computer and the remote server.
  • the system detects that the bandwith is such that the image of the CD ROM should be downloaded onto the user's computer system, the user is presented with the option to order the CD ROM. If the user selects to order the CD ROM, then an image of the CD ROM is copied to the user's hard drive. This copying may take place at an off peak time, such as a time when there is a low load on the server that is storing the CD ROM images. Such time may depend on the particular usage patterns of the CD ROM images by the users. For example, if the CD ROM images correspond to computer games, and these computer games are typically played between 4:00 p.m. or 5:00 p.m.
  • the downloading of the CD ROM image would take place after this time of high usage. For example downloading may take place between midnight and 8:00 a.m., or between midnight and 4:00 p.m. or at other time ranges to avoid times of high system load. If bandwith is sufficient for emulation of the CD ROM without copying the CD ROM on to the user's computer system, then the user may be presented with a play button. When the user clicks the play button, the title plays immediately on the user's machine.
  • a graphical computer program such as a game title
  • the accessed data is stored on the user's system. Later, when this data is needed again, it is accessed from the local storage device on which it is stored.
  • An advantage of such an approach is that communications bandwith between the user's system and the remote server is conserved. For example, if the graphical computer software program displays the same screen that the program has displayed before, the computer program that emulates the CD ROM drive accesses the screen from the user's storage device, such as the hard drive, rather than from the remote server. Data not previously accessed may be accessed over the network, and data already accessed is accessed via the storage device locally coupled to the user's computer.
  • a space may be reserved on the user's storage device for such storage of data from the remote server. As this storage space becomes full, some of the older data may be replaced by newer data.
  • the determination as to which older data may be replaced may be made by a variety of methods. For example, the least recently used data may be replaced with the newer data form the remote server.
  • the user may select the amount of storage space to be utilized for such local caching of data received from the remote server. The user may make this determination via a window in a user interface.
  • the user interface may refer to such storage space as shelf space.

Abstract

L'invention concerne un procédé de traitement de données destiné à un logiciel informatique. Elle concerne également un dispositif permettant de jouer à des jeux. Ce dispositif comprend un premier serveur relié à un réseau informatique, lequel serveur comprend, à son tour, une liste de jeux sur ordinateur ; un second serveur relié au réseau informatique et comprenant un dispositif de mise en mémoire contenant des images de CD ROM correspondant à au moins certains des jeux figurant dans la liste des jeux sur ordinateur ; un ordinateur client relié au réseau informatique, pourvu d'un code lisible par un ordinateur permettant à un utilisateur de sélectionner un jeu parmi les jeux figurant dans la liste. Le code lisible par un ordinateur autorise l'accès à une image d'un jeu parmi les images des CD ROM contenus dans le dispositif de mise en mémoire compris dans le second serveur. Le code mémorise au moins une partie de l'image sur le dispositif de mise en mémoire relié localement à l'ordinateur client et il permet au jeu d'être exécuté au moins partiellement compte tenu de l'image stockée dans le dispositif de mise en mémoire relié localement à l'ordinateur client.
