Blu-ray Disc Button State Transition for Popup Menu Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Blu-ray Disc technologies face limitations in executing certain actions, such as displaying a popup menu and skipping chapters, due to restrictions on command execution sequences, particularly after changing reproduction positions, which prevents seamless navigation and menu control.
Innovation Solution
The solution involves a method where a first button is put into an execution state, followed by a second button being automatically put into a selected state, then a third button is put into an execution state, allowing the execution of commands associated with the second button, thereby enabling the execution of commands like turning off a popup menu after changing reproduction positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a command for changing reproduction positions is executed, then the reproduction position is successfully changed, but subsequent commands cannot be executed due to command execution restrictions
Solution Approach 1:
The patent segments the button structure into multiple functional states (normal state, selected state, execution state) and associates different commands with different state transitions. This allows the system to separate the position-changing function from the menu-control function, enabling both to be executed sequentially without conflict by using different button state transitions rather than sequential commands in a single button.
2Adaptability or versatility
If commands are arranged in sequence with delimiters, then command execution order is controlled, but certain functional combinations (like turning off popup menu after chapter skip) cannot be realized
Solution Approach 1:
The patent adds a temporal dimension to button functionality by defining automatic state transitions that occur at specific moments (e.g., when reproduction position changes). This allows the system to execute multiple functions (chapter skip + menu close) through a single button press by utilizing different time points in the reproduction process, rather than requiring sequential command execution.
3Reliability
If button commands are restricted to avoid conflicts, then system stability is maintained, but user interaction flexibility is reduced
Solution Approach 1:
The patent makes the button functionality dynamic by allowing the same button to perform different functions depending on the current reproduction state and button state transitions. The button can automatically transition between normal, selected, and execution states based on reproduction position changes, enabling flexible user interaction while maintaining system stability through predefined state transition rules.

AI summary
Disclosed herein is a recording media recorded with data of a plurality of buttons configuring a group arranged at a same position and selectively executed, each of the plurality of buttons is one of a button for use in an operator screen for prompting a user for an operation including a button image shifting between three states of a normal state, a selected state, and an execution state and a button in which a shift is automatically made from a selected state to an execution state to execute a command, the plurality of buttons including, a first button, and a second button and a third button that belong to the group to which the first button belongs, the second button and the third button each including a flag indicative of automatic transition from a selected state to an execution state.
