Storage Medium Integrating AV Data and Java Application Programs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional storage media for audio-visual (AV) data lack the capability to record and reproduce program data for user-interactive functions such as games or chatting, limiting the interactive experience with AV content.
Innovation Solution
A storage medium and apparatus that includes movie mode data, program mode data with JAVA application programs, and management information to control the execution of these programs, allowing for both basic AV reproduction and enhanced interactive functions by determining the reproduction mode and executing JAVA applications accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional storage media only record basic AV data, then the storage structure remains simple, but user interactive functions such as games or chatting cannot be provided
Solution Approach 1:
The storage medium is segmented into distinct data structures: AV data, program data, and management information are stored as separate but integrated components. This allows the system to maintain basic AV reproduction functionality while adding program-based interactive functions without creating a completely new complex structure.
Solution Approach 2:
The storage medium is designed to serve multiple functions: it can reproduce basic AV data (movie mode) and execute program-based applications (program mode) using the same physical medium. The system data and management information enable the medium to adapt between different functional modes without requiring separate storage devices.
2Adaptability or versatility
If program data is added to storage media with AV data, then user interactive functions are enabled, but the data structure becomes more complex
Solution Approach 1:
The data structure is segmented into clearly defined components: AV data for basic reproduction, program data for interactive functions, and management information for controlling execution. This segmentation allows each component to be independently managed while working together as an integrated system.
Solution Approach 2:
System data and management information act as intermediaries between the AV data and program data, and between the storage medium and the reproducing apparatus. These intermediary structures enable coordinated execution of multiple applications and proper mode switching without requiring complex direct interactions between all data elements.
3Adaptability or versatility
If multiple application programs are recorded in the storage medium, then additional functions are provided, but the management and control of these programs becomes more difficult
Solution Approach 1:
The management information structure enables applications to self-manage their execution contexts. Each application program is associated with management information that defines its execution parameters, allowing the reproducing apparatus to automatically manage multiple applications without requiring complex external control mechanisms.
Solution Approach 2:
The system uses parameter changes in the management information to control application execution. By modifying execution parameters (such as mode information indicating movie mode or program mode, and application-specific control parameters), the system can dynamically manage multiple applications and switch between different functional states.
