Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional broadcasting services require significant investments for infrastructure and personnel, limiting accessibility to specific users, and next-generation optical disks face challenges in storing high-capacity HD video data.
Innovation Solution
A media playback apparatus that reads content reception information from disk media to establish a connection with an external content provider, allowing for the reception and provision of multimedia content, including video, audio, and data applications, using Blu-ray, HD-DVD, or DVD specifications, with features like authentication, viewer identification, and scene-by-scene executable data applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional broadcasting service is provided through satellite network or dedicated network, then stable bandwidth and QoS are secured, but infrastructure investment cost increases significantly
Solution Approach 1:
The patent introduces a head-end system as an intermediary that consolidates content delivery functions. Instead of each receiver needing direct connection to multiple content sources, all content distribution is mediated through the head-end system, which manages content reception, processing, and distribution to multiple receivers efficiently.
Solution Approach 2:
The head-end system performs multiple functions including content reception, authentication, processing, and distribution to various receivers. This multi-functional approach eliminates the need for separate infrastructure at each receiver location, reducing overall infrastructure investment while maintaining reliable content delivery.
2Adaptability or versatility
If custom-made receivers are deployed for internal corporate broadcasting, then specific user requirements are met, but device complexity and manufacturing cost increase
Solution Approach 1:
Instead of making each receiver fully custom-made with all possible features, the system implements partial customization through authentication mechanisms. Receivers only obtain and process content they are authorized to access, achieving user-specific content delivery without requiring complex custom hardware for each device.
Solution Approach 2:
The system uses dynamic authentication and content allocation where receiver capabilities and content access rights are determined at runtime based on user credentials. This allows adaptable content delivery to specific users without requiring static custom-made receivers for each user scenario.
3Quantity of substance
If conventional optical disks are used for HD video storage, then compatibility is maintained, but storage capacity is insufficient
Solution Approach 1:
The system changes the physical parameters of optical disks by transitioning from red laser (650nm) to blue laser (405nm) technology. This parameter change enables significantly higher storage capacity (15-25GB per layer) while maintaining the basic optical disk form factor and compatibility with next-generation drives.
Solution Approach 2:
The patent introduces multi-layer disk structures (dual-layer, quad-layer, octa-layer) as an additional dimension of storage capacity. By stacking multiple recording layers within the same disk physical dimensions, the system achieves 30-200GB capacity while maintaining disk compatibility with next-generation optical drives.
