HD DVD Authoring Method for Seamless Application Invocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of commercially available software tools that facilitate consumers in authoring High Definition Digital Versatile Disc (HD DVD) content, leading to cumbersome and inconvenient interaction during playback adjustments.
Innovation Solution
A machine-implemented authoring method for HD DVD that allows users to specify titles, generate or modify playlist files, and set relationships between titles and applications, enabling seamless playback adjustments without interrupting video playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a standard DVD format is used for playback, then video quality and storage capacity are maintained, but user interaction becomes cumbersome when adjusting playback parameters
Solution Approach 1:
The patent applies preliminary action by pre-defining multiple playback parameter sets (playback parameter groups) that are stored on the disc before playback. When a user wants to adjust parameters, they can simply select from pre-configured options rather than making adjustments in real-time, thus avoiding playback interruption while maintaining ease of operation.
2Ease of manufacture
If commercially available software tools are used for HD DVD authoring, then authoring capability is provided, but such tools are currently unavailable for consumers
Solution Approach 1:
The patent enables self-service by providing consumers with the capability to author HD DVD content themselves using standard computer hardware and software. The system allows users to create playlist files and associate them with video files without requiring specialized commercial authoring tools, thus making the authoring process accessible to general consumers.
3Adaptability or versatility
If playlist files are manually created and modified, then HD DVD content can be authored, but the process becomes complex and difficult for consumers
Solution Approach 1:
The patent introduces an intermediary approach by using a computer's file system and standard software applications as mediators between the user and the HD DVD authoring process. Instead of requiring specialized authoring software, the system leverages existing computer capabilities to create and manage playlist files, significantly reducing the perceived complexity for consumers.

AI summary
A machine-implemented authoring method for a high definition digital versatile disc includes: receiving a user-specified title; enabling a user to specify an initial playlist file and at least one application, the initial playlist file being one of a template-generated raw playlist file and a user-authored raw playlist file; and in response to a user-inputted command, modifying the initial playlist file to set corresponding relationship between the user-specified title and the at least one application such that, during playback of the user-specified title, the at least one application set to correspond to the user-specified title can be invoked and executed.
