Overlay Menu System for Seamless Video Playback Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current DVD systems interrupt playback when users need to access menu options, limiting user-friendly navigation and functionality during video streaming.
Innovation Solution
A menu system that overlays video on DVD players, allowing users to select options and control playback features without interrupting the video stream, including dynamic control of multiple video streams and audio mixing, with on-screen menus and cursor navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional main menu system is used, then users can access options and control features, but playback is interrupted and users must return to the main menu
Solution Approach 1:
The menu system is segmented into multiple layers including a main menu and context-sensitive submenus that appear at different positions on the screen. Users can access different menu functions without returning to a single main menu, reducing navigation time and playback interruptions.
Solution Approach 2:
The patent introduces a spatial dimension to menu navigation by placing different menu types at different screen positions (e.g., upper left for main menu, lower right for context menus). This allows users to access various functions simultaneously without temporal interruption, transforming the traditional linear menu access into a parallel spatial arrangement.
2Productivity
If a menu system overlays video during playback, then users can select options without interrupting playback, but the menu system complexity increases
Solution Approach 1:
The menu system is designed to be dynamic rather than static. Context-sensitive menus appear and disappear based on user interaction and playback state, with different menu options available at different screen positions. This dynamic behavior allows continuous playback while providing complex functionality through adaptive menu structures.
Solution Approach 2:
The patent implements nested menu structures where context-sensitive submenus can be embedded within the overlay system without requiring users to exit the playback view. Multiple menu levels are nested within the same screen space, allowing users to access complex features while maintaining continuous video playback in the background.

AI summary
A method and a system of displaying a user interface to control playback and features that may be associated with a prerecorded media. A media player, such as a DVD player, a personal computer, a home media server, a high definition video player, an optical player, a hard drive based player, or a software DVD-ROM player receives streams of video from different media and displays its content. Simultaneously, and without interrupting the video playback, a user interface is overlaid on the video image. The user interface may include menu selections to control the playback of the video including scene selection, settings, and viewing rights. The user interface may include menu selections to control features associated with the video such as Documentaries, Games, Purchases, Activities, Commentaries, Outtakes, Karaoke, Trailers, Songs, Wishlists, and Events.
