Automated DVD Conversion for On-Demand Network Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video on demand (VOD) systems fail to provide an engaging viewer experience due to slow session initiation, limited interactive features, and the inconvenience of accessing DVD content, which lacks on-demand availability and is often expensive and prone to scratches, with manual conversion to network format being time-consuming and costly.
Innovation Solution
A system for automated DVD conversion, on-demand merchandising, time and location-sensitive distribution, and ubiquitous presentation, enabling decryption, demultiplexing, reorganization, conversion to XML, transcoding, and packaging of DVD content for delivery over networks, compatible with various VOD servers and set-top boxes, allowing interactive features and enhanced user experience without the need for physical DVD ownership.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual conversion of DVD content to network format is performed, then DVD content can be delivered over network, but the process is time-consuming and expensive
Solution Approach 1:
The system performs preliminary actions by automatically decrypting, demultiplexing, and converting DVD content to network-compatible formats in advance, eliminating the need for time-consuming manual conversion when content is requested. The automated conversion process prepares content for network delivery beforehand, resolving the contradiction between adaptability and time loss.
Solution Approach 2:
The patent replaces manual mechanical conversion processes with automated electronic conversion systems. The system automatically decrypts CSS-encrypted DVD content, demultiplexes video/audio/subtitle streams, and converts them to network formats without human intervention, dramatically reducing conversion time and cost while maintaining delivery capability.
2Ease of operation
If interactive DVD features are provided on VOD platforms, then viewer engagement increases, but system complexity increases
Solution Approach 1:
The system achieves universality by creating a standardized conversion framework that handles multiple DVD features (interactive menus, scene selection, audio tracks, subtitles, bonus materials) through a single automated process. This multi-functional approach enables rich viewer engagement without proportionally increasing system complexity, as the same conversion infrastructure supports all interactive features.
Solution Approach 2:
The patent introduces an intermediary conversion system that translates complex DVD interactive features into network-compatible formats. This intermediary layer handles the complexity of decrypting, demultiplexing, and converting various DVD elements (menus, scenes, audio, video) into standardized network streams, shielding the VOD platform from direct complexity while preserving all interactive capabilities.
3Ease of operation
If DVD content is made available on-demand over network, then viewer convenience increases, but conversion costs increase
Solution Approach 1:
The system implements self-service by automatically performing all conversion operations without manual intervention. When DVD content is requested, the system autonomously decrypts, demultiplexes, and converts the content to network format, then delivers it on-demand. This automated self-service approach eliminates labor costs associated with manual conversion while providing convenient on-demand access to viewers.

AI summary
A method for pruning and grooming DVD content into a format compatible to be viewed over a network is disclosed. The method provides for automated DVD conversion. The method provides for removing and editing DVD content that is not desirable to be delivered over the network and adding and editing additional content that is desirable to be delivered over the network. The method provides for navigational enhancement that provide: tie-ins to on demand portals; key-mapping; button highlighting; intra-menu navigation; inter-menu navigation and DVD disc merge capability.
