Abstract

An interactive video-audio-computer open architecture system and method with dynamically reconfigurable software providing a virtual device interface buffering applications from hardware and with extended flexibility and universal compatibility with the myriad of industry hardware products and standards (videodisc players, graphics, microprocessors, computers, video and audio sources, etc.), all with transparency to the user and without the requirement of modification of application software irrespective of which hardware product is connected to the system.

Claims

1. A method of interactive video-graphics-audio-computer open architecture operation for providing multi-media command and application functions through specific requested application programs that control the operation of requested multi-media hardware devices of various types including video overlay devices, video/graphics display devices, video disc player products, audio recording and playback devices and computer user input devices, that comprises,

providing a modular interface buffering software layer between the application programs and the operating hardware required for performing the same, including providing multi-media command and control functions that manage the control and presentation of multi-media data and storage and display for said application programs independently of the type of the requested hardware device and its data format;

optimizing the performance of such multi-media applications by interleaving data-intensive tasks, including loading graphics and audio files and dynamically loading at run-time only those descrete functions of multi-media command and control requested by the specific application programs under execution; and

automatically selecting at run-time the hardware devices required to deliver the multi-media command and control functions requested, allowing the application program to be used with the hardware device requested without requiring any modification to the application software.

2. A method as claimed in claim 1 and in which said software schedules use only of said videodisc player products, communicates the input/output requirements, manages overlay of computer graphics files, and links to external software to incorporate these capabilities into such products.

3. A method as claimed in claim 1 and in which the step is performed of effecting said command and control functions with transparency to the user.

4. A method as claimed in claim 3 and in which the step is performed of configuring said software to provide not only universal videodisc player product control commands but also a universal set of X/Y input commands so as to allow device and product changes without specific application programs or changes.

5. A method as claimed in claim 4 and in which the step is performed of configuring said software to enable the simultaneous use of multiple devices.

6. A method as claimed in claim 4 and in which the step is performed of causing said software to provide commands not available on some videodisc player products which will work on all such players.

7. A method as claimed in claim 4 and in which the step is performed of causing said software to support one or more of digital audio facility, fast loading of high density graphics files, programming language interfaces, and support of PAL and NTSC videodisc players.

8. A system for interactive video-graphics-audio-computer open architecture operation for providing multi-media command and application functions through specific requested application programs that control the operation of requested multi-media hardware devices, having in combination with any of a myriad of such requested hardware devices including video disc players, graphic sources, audio and video sources, and computer input/output devices including touch screen devices,

an executive system with multi-media command and control functions that manage the control and presentation of multi-media data and storage and display devices for application programs independently of the type of the requested hardware device and its data format, providing a virtual device interface with said hardware device that enables the performance of requested specific applications thereby and comprising a modular interface buffering software layer between the application programs and the operating hardware device required for performing the same, including means for establishing discrete modules of function of multi-media command and control requested by the specific application programs;

means for dynamically loading those discrete modules of function at run-time;

said software including means for restricting such loading to substantially only the functionality required to run the specific requested application; and

means for enabling the software dynamically to reconfigure itself by scheduling the use only of said specific application programs to the different hardware devices connected to the system to control requested hardware devices including the videodisc players, to communicate the input/output requirements, to manage overlay of graphics, and to link to external software to incorporate such capabilities into the hardware devices and without requiring modification to the applications software.

9. A system as claimed in claim 8 and in which means is provided within the software to effect the interfacing and control with transparency to the user.

10. A system as claimed in claim 9 and in which means is provided to generate not only universal videodisc player control commands but also a universal set of X/Y input commands so as to allow product changes without specific application programs or changes.

11. A system as claimed in claim 10 and in which the software further enables the simultaneous use of multiple products.

12. A system as claimed in claim 10 and in which said software enables commands not available on some videodisc player which will work on all such products.

13. A system as claimed in claim 10 and in which said software supports one or more of digital audio facility, fast loading of high density graphics files, programming language interfaces, and support of PAL and NTSC videodisc players.

14. A system as claimed in claim 10 and in which the system software comprises a two-dimensional matrix of executive file modules, each capable of communicating similarly with any other module, and with each row representing a layer of functionality, and with the highest row controlling the interface with other programs and the lowest row controlling the particular product or device.

15. A system as claimed in claim 14 and in which the columns of the matrix of modules represent different service classes individually selectable in accordance with the specific desired application, and the matrix rows are logical layers of functionality.

16. A system as claimed in claim 15 and in which the service classes modules include one or more of system overlay, videodisc player, X/Y input commands, image and digital audio services.

17. A system as claimed in claim 16 and in which the said logical layers of functionality in the successive matrix module rows include one or more of a kernel module, class manager modules, device manager modules and device driver modules.

18. A system as claimed in claim 17 and in which said kernel module is provided with memory, queue management, realtime event services, configuration information, interrupt services, communication and device information, and the same further communicates with the application program, dispatching requests to said class manager modules.

19. A system as claimed in claim 18 and in which said class manager modules pass the requests from the application to lower modules in the matrix.

20. A system as claimed in claim 19 and in which the said image services class manager module also provides the function of reading and writing image disc files.

21. A system as claimed in claim 19 and in which said device manager modules are connected to communicate with specific external devices including said videodisc players, touch screens, mouse devices and link processors.

22. A system as claimed in claim 21 and in which said device driver modules are connected to control specific internal devices including communication ports, graphic adapters and link processors through I/O and memory mapped registers and interrupts.
