Abstract

A dedicated apparatus for playing unmodified prerecorded software in a home computer system, and more particularly an apparatus, housed in a home entertainment system chassis, for playing in a home entertainment environment the existing body of interactive multimedia software that has been formatted and published for compatibility with standard personal computer platforms such as the MPC CD-ROM platform. Video and audio output signals are generated in response to the processing of the multimedia software program, which are fed to the home entertainment system for presentation to an audience. A further aspect is the provision of a "drop & play" feature which automatically initiates playing of multimedia software in a sequence that appears to be similar to playing audio Cds, i.e., without requiring any further action from a user after selecting play. This feature is in part provided by a table containing installation information for each of numerous multimedia software titles; entries in this table are preferably indexed by an identifier that can be uniquely derived from a given CD-ROM or other published multimedia media such as a diskette.

7. A multimedia apparatus as in claim 5, wherein the processing device is further structured and configured to derive said unique identifier by computing a hash function derived from a file allocation table of the portable recording medium.

8. A multimedia apparatus as in claim 1, wherein the processing device is configured and structured to be backward compatible to play those software programs that are formatted to be executed on at least one personal computer platform without requiring prior modification to such software programs.

9. A multimedia apparatus as in claim 8, wherein the processing device is compatible with MPC (multimedia personal computer) standard.

10. A multimedia apparatus as in claim 1, wherein the processing device is structured and configured to identify the software program independent of external networks.

11. A multimedia apparatus as in claim 1, wherein the output means is structured and configured to provide the image data in a format compatible for display by a television monitor in the home entertainment system.

12. A multimedia apparatus as in claim 1, wherein the processing device is structured and configured to perform personal computer tasks and the output means is structured and configured to provide the image data in a format that does not require a computer monitor.

13. A home entertainment system comprising:

input means for receiving user commands;

display means for presentation of image data;

audio means for presentation of audio data;

one or more audio or video components for playing audio or video recordings; and

a multimedia apparatus having capability of playing software programs, comprising;

reading means for receiving a portable recording medium and reading a software program stored thereon;

a processing device structured and configured to identify the software program being read by the reading means and determine whether said software program needs to be installed or has already been installed, and should it need to be installed, whether installation information relating to the software program being read by the reading means is available to the processing device to be used to perform an automatic installation of the software program, said processing device further structured and configured to begin playing the software program if it has already been installed or automatically initializing an installation of the software program prior to playing the software program if the installation information is available; and

output means for providing audio and image data resulting from the playing of the software program to the audio means and the display means.

14. A home entertainment system as in claim 13, wherein the reading means is a CD-ROM drive and the portable recording medium is a CD-ROM.

15. A home entertainment system as in claim 13, further comprising a database containing installation information relating to particular software programs identifiable for playing by the multimedia apparatus, wherein the processing device is structured and configured to determine whether installation information relating to the software program being read by the reading means is available to the processing device by looking up the database.
