Multimedia Disk Menu Navigation via Cursor-to-Keyboard Translation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing use of high-definition (HD) DVDs poses a challenge as manufacturers must define specific mouse operation actions, increasing software design costs and causing inconvenience when users try to operate HD DVDs on computers using a mouse, as there is no standard for mouse operations in DVD specifications.
Innovation Solution
A method where an item in the menu is shifted or selected based on the relative position between a cursor controller and a focus point, translating input events from the cursor controller into keyboard events, allowing for navigation using direction keys (up, down, left, right) or input keys, enabling seamless operation of multimedia disks, including HD DVDs, using a cursor controller like a mouse, joystick, or touch-pad.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mouse operation actions are defined for each optical disk according to HD DVD specifications, then the user can operate the menu using a mouse, but the software designing cost increases
Solution Approach 1:
The patent applies universality by creating a standardized mapping relationship between mouse operations and menu operations that can be applied across all HD DVD menus. Instead of defining custom mouse actions for each disk, the system establishes universal mapping rules that translate mouse movements, clicks, and gestures into standardized menu navigation commands (up, down, left, right, select, etc.), making the solution applicable to all multimedia disks without additional design effort.
Solution Approach 2:
The patent changes the parameter of operation mapping from disk-specific custom definitions to standardized parameter mappings. By defining a universal set of mouse operation parameters (movement direction, click type, hold duration) and mapping them to standard menu commands, the system eliminates the need for custom parameter definitions for each disk while maintaining full operational capability.
2Device complexity
If no mouse operation actions are configured for optical disks, then the software design cost is reduced, but the user cannot operate the menu using a mouse
Solution Approach 1:
The patent introduces an intermediary layer - a standardized mapping relationship - that bridges the gap between mouse operations and menu operations. This mapping acts as a mediator that translates generic mouse inputs into meaningful menu commands without requiring disk-specific configurations. The intermediary mapping table serves as a universal translator between the cursor controller and the menu system, enabling mouse operation without increasing software design complexity.
3Adaptability or versatility
If different operating methods are used for DVD player and optical disk drive, then each device can be optimized for its specific hardware, but the user experience becomes inconsistent
Solution Approach 1:
The patent applies universality by establishing a standardized mouse-to-menu mapping that works consistently across different multimedia disk formats (DVD, HD DVD, etc.). This universal mapping ensures that users experience consistent behavior regardless of which device or disk format is being used, while still allowing each device to utilize its specific hardware capabilities through the standardized interface.

AI summary
A method for operating a menu of a multimedia disk is provided. The method includes first selecting an item in the menu as a focus point and using a cursor controller for moving a cursor in the menu. An input event issued by the cursor controller is then translated into an input event of a key on a keyboard based on a relative position between the cursor and the focus point, so as to shift or select a target title. Consequently, a user can operate the menu of the multimedia disk in a computer system by using the cursor controller, and the convenience of operating the menu can be improved.
