Disc Player Fast-Forwarding First Play Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Optical disc player devices, particularly those used in vehicles, face challenges in reducing the time to transition from a first play to the main content due to power interruptions and the inability to perform user operations during vehicle movement, leading to prolonged playback times, especially for BD-J titles.
Innovation Solution
A disc player device equipped with a signal processing unit, menu detection unit, and main part detection unit that automatically performs user operations to expedite the transition to the main content by analyzing data structures and determining the playback state, allowing for faster playback even without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the first play is played at normal speed to ensure proper introduction and demonstration, then the quality of user experience is maintained, but the time to reach the main content becomes excessively long
Solution Approach 1:
The system performs preliminary detection of menu state and main part state during the first play, automatically preparing to switch to fast forward mode when the main content is detected, thereby eliminating the need for manual user intervention and reducing the time to reach main content
Solution Approach 2:
The disc player device automatically detects playback state transitions and performs fast forwarding without requiring user operations, making the system self-aware and self-adjusting based on the detected menu or main part states
2Adaptability or versatility
If the disc player device is used in a vehicle where power is frequently interrupted, then mobility and convenience are improved, but the playback time increases because the first play must be repeated after each power interruption
Solution Approach 1:
The system continuously monitors and detects the playback state (menu state or main part state) and uses this feedback information to automatically adjust playback speed, ensuring that after power interruptions, the device can quickly resume and reach the main content without repeating the entire first play
Solution Approach 2:
The system performs preliminary state detection and automatically transitions to fast forward mode when the main part is detected, so that after power interruptions, the playback can quickly skip through the first play introduction and reach the main content efficiently
3Adaptability or versatility
If BD-J titles are played in vehicle environments with frequent power on/off, then the device can be used portably, but continued playing is not practical due to memory requirements
Solution Approach 1:
The disc player device automatically detects playback states and performs fast forwarding without requiring user intervention or complex memory management, making the system self-sufficient and eliminating the need for continued playing functionality in vehicle environments

AI summary
According to the present invention, provided is a disc player device (100) that automatically performs a user operation for playing a first play that is a title played before playing of a main part or display of a menu, faster than playing at a normal speed after the power is applied. A signal processing unit (15) is provided with a menu detection unit (17) to analyze structure of various data and detect a menu state, a main part detection unit (18) to detect playing state of a main part from the various data, and a user operation unit (19) to automatically perform a user operation for playing a title currently being played faster than playing at a normal speed until a menu state is detected by the menu detection unit (17) or a playing state of a main part is detected by the main part detection unit (18) when the signal processing unit (15) determines that a First Playback exists after the power is applied.
