ABSTRACT:

COPYRIGHT NOTICE
A portion of the disclosure of this patent document contains material which is subject to copyright protection. The copyright owner has no objection to the facsimile reproduction by anyone of the patent disclosure, as it appears in the Patent and Trademark Office patent files or records, but otherwise reserves all copyright rights whatsoever.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to methods and apparatus for providing codes describing hypertext objects in an intermediate language, and more particularly, to methods, systems, and apparatus for decoding said codes in an intermediate language on devices with limited computing power and resources.
2. Description of the Prior Art
Programs and data files written in standard object specifying languages such as HTML and JAVA require a large amount of computing power and resources in order to operate at an efficient level. These programs and data files are typically executed on personal computer (or more powerful) platforms.
In order to have a device that can process files written in these object specifying languages and at the same time minimize the manufacturing cost of these devices, the device and the associated software would have to be modified and streamlined for hardware with limited power and capabilities. Prior art methods and systems generally achieve this goal by minimizing or eliminating certain standard features or functionalities. A user of such systems or methods cannot therefore benefit from the full functionalities provided by the object specifying languages.
Although, one prior art technology provides for Video-CDs (VCDs) and VCD players. Such players are generally limited function appliances, where it can only play VCD discs and not much more. It would be desirable to add additional capabilities to these players since the requisite hardware for processing object specifying language programs and data files is already in place.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide a system having minimal computing power, peripherals, and resources and yet capable of efficiently processing codes written in an object specifying language such as programs and data files written in HTML and JAVA.
It is another object of the present invention to provide a method for decoding codes describing objects in an intermediate language on a system with minimal computing resources.
It is yet another object of the present invention to provide a method for processing codes in a simple scripting language on a system with minimal computing resources.
Briefly, a presently preferred embodiment of the present invention provides a method for retrieving, decoding, and processing codes in an intermediate language generated from object specifying languages such as HTML and JAVA. The codes in the intermediate language are decoded and processed to generate a screen of information with selections thereon for the user. The file corresponding to the chosen selection is retrieved, decoded, processed, and displayed to the user again for selection. Codes in a simple scripting language are also provided to facilitate the processing of commands, and the codes can be embedded in the files or stored as separate files.
As part of a presently preferred embodiment of the present invention, a system having the capability to play back a CD/VCD or other types of media format (physical, optical format and/or software format) and the capability to perform a large variety of functions is disclosed. The system can be a dual processor system where one processor is a digital signal processor (DSP) having its operations controlled by another processor, such as a RISC processor.
An advantage of the present invention is that it provides a system having minimal computing power, peripherals, and resources and yet capable of efficiently processing codes written in an object specifying language such as programs and data files written in HTML and JAVA.
Another advantage of the present invention is that it provides a method for decoding codes describing objects in an intermediate language on a system with minimal computing resources.
Yet another advantage of the present invention is that it provides a method for processing codes in a simple scripting language on a system with minimal computing resources.
These and other features and advantages of the present invention will become well understood upon examining the and reading the following detailed description of the invention.
