Converting DVD-Video Interactive Content to HTML5 via Object Model
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The decline in popularity of physical media, such as DVDs, has led to a need for converting interactive multimedia content authored for distribution via physical media into formats suitable for electronic sell-through, as existing technologies do not efficiently support the electronic distribution of multimedia content originally designed for physical media.
Innovation Solution
A content authoring system is used to build an object model of interactive multimedia content, automatically author a user interface, and pack transcoded content into container files, enabling electronic distribution by converting content formats from DVD-Video or BD-ROM specifications to HTML5, which supports playback on various devices without the need for additional plugins.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multimedia content is authored for distribution via physical media (DVD), then the content can be delivered with high quality and interactive features, but the content cannot be efficiently distributed electronically without re-authoring
Solution Approach 1:
The patent introduces an intermediary conversion system that translates DVD-Video authored content into web-compatible formats. This intermediary process includes parsing DVD structures, extracting media elements, and reassembling them into HTML5-compatible packages, thereby enabling electronic distribution without requiring complete re-authoring of the content
Solution Approach 2:
The conversion system changes key parameters of the content packaging format, transitioning from DVD-Video's ISO 9660 file systems and VOB/IFO/BUP file structures to web-compatible HTTP-deliverable formats with HTML5 packaging. This parameter transformation enables the same content to be distributed through different channels with minimal modification
2Productivity
If content is converted to HTML5 format for electronic distribution, then electronic sell-through becomes efficient, but playback compatibility across various devices must be ensured
Solution Approach 1:
The conversion system creates universally compatible HTML5 packages that can be played across multiple device types including smartphones, tablets, computers, and smart TVs. The packaged content uses standardized HTML5 video and audio tags that are natively supported by modern browsers on various platforms, ensuring wide device compatibility while maintaining efficient electronic distribution
3Ease of operation
If DVD-Video content structure is maintained, then interactive features are preserved, but the content cannot be played back on devices without additional plugins
Solution Approach 1:
The patent replaces the DVD-Video mechanical playback system (which requires DVD players and specific disc structures) with a software-based HTML5 playback system. Interactive features originally implemented through DVD command structures are translated into JavaScript-based interactions within HTML5 pages, eliminating the need for proprietary plugins while preserving interactivity

AI summary
Systems and methods for converting interactive multimedia content authored for distribution via a physical medium for electronic distribution are disclosed. One embodiment of the invention includes building an object model of interactive multimedia content authored for distribution via a physical medium using a content authoring system, automatically authoring a user interface based upon the object model using the content authoring system, and packing the transcoded multimedia content into at least one container.
