Unified Playback Information Package for BD-J Digital Content
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional playback apparatuses supporting the BD-J specification require multiple configurations of virtual packages to play both main and auxiliary digital content, leading to increased time and complexity in providing digital content to users.
Innovation Solution
A method is introduced where a playback information package is generated by combining main and auxiliary information according to a playback sequence, allowing the playback apparatus to configure a single virtual package for both types of content, thereby reducing configuration time and complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple virtual packages are configured separately for main and auxiliary digital content, then each content type can be played independently, but the configuration time and system complexity increase significantly
Solution Approach 1:
The patent combines separate virtual package configurations for main and auxiliary digital content into a single integrated virtual package. The playback information package includes both main content information (BUMF, playlist, clip information) and auxiliary content information (advertisement, subtitle, audio track) in one unified structure, eliminating the need for multiple separate configurations and reducing system complexity while maintaining full playback functionality
Solution Approach 2:
The single virtual package structure is designed to handle multiple content types (main content, advertisements, subtitles, audio tracks) through a universal configuration framework. This multi-functional approach allows the same virtual package to manage diverse content delivery scenarios without requiring separate specialized configurations for each content type
2Ease of manufacture
If separate virtual package configurations are created for main and auxiliary digital content, then content can be managed independently, but the time required to provide digital content to users increases
Solution Approach 1:
The patent performs preliminary integration of main and auxiliary content information into a unified playback information package before content delivery. By pre-configuring the virtual package structure with all necessary content references (main content, advertisements, subtitles, audio tracks) in one operation, the system eliminates time-consuming sequential configuration steps and enables faster content provisioning
3Ease of operation
If multiple virtual package configurations are used, then detailed control over each content type is achieved, but the overall process becomes more complex and time-consuming
Solution Approach 1:
The patent merges the control mechanisms for main and auxiliary content into a unified virtual package management system. The single configuration structure maintains detailed control capabilities for each content type (through organized information sections for main content, advertisements, subtitles, and audio tracks) while streamlining the overall configuration process, thereby improving content delivery efficiency without sacrificing operational control
