Operation Mode Object for Seamless Display Rate Initialization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In stereoscopic playback systems, display interruptions occur frequently due to changes in display rate, leading to uncomfortable user experiences, especially when switching between titles, as conventional solutions require significant hardware resources and increase implementation costs.
Innovation Solution
A recording medium and playback device system that initializes the display rate and resolution simultaneously, shifting the timing of interruptions to minimize the number of display disruptions by writing 'resolution' and 'display rate' combinations into an operation mode object, allowing for seamless transitions between titles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display rate is changed during playback, then the playback can be adapted to different display devices, but the transmission deadline changes causing display interruptions and requiring cable re-connection
Solution Approach 1:
The patent applies preliminary action by pre-defining multiple operation mode objects with different display rate combinations before playback. When a title switch occurs, the system selects from these pre-configured modes rather than dynamically changing parameters, thus avoiding transmission deadline violations and display interruptions while maintaining adaptability to different display devices
Solution Approach 2:
The patent implements parameter changes by creating discrete operation mode objects that contain specific combinations of resolution and display rate parameters. Instead of continuous parameter adjustment, the system switches between predefined parameter sets, ensuring that each mode corresponds to valid transmission specifications and avoiding cable re-connection events
2Reliability
If conventional upconversion technology is used to prevent display interruptions, then playback continuity is improved, but enormous hardware resources are required and implementation cost increases
Solution Approach 1:
The patent merges the title switching function with the display rate initialization function. By initializing the display rate at the same time as title switching occurs, the system achieves playback continuity without requiring separate upconversion hardware, thereby reducing device complexity while maintaining reliability
Solution Approach 2:
The patent creates multiple operation mode objects that are copies or variants of a base mode, each with different resolution and display rate combinations. This allows the system to select the appropriate pre-configured mode for the current display device without performing real-time upconversion, reducing hardware requirements while ensuring continuous playback

AI summary
A recording medium 100 on which an index table, an operation mode object, and byte-code applications are recorded. The index table shows correspondence between one or more titles and one or more operation mode objects. The operation mode object includes an application management table and display rate initialization information. The application management table indicates a byte-code application to be started to a playback device when a title corresponding to the operation mode object is selected as a current title. The display rate initialization information indicates how to initialize a display rate of a display device connected to the playback device when the title corresponding to the operation mode object is selected as the current title.
