Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital broadcasting systems face limitations in expanding channel or service coverage and ensuring data exchange between digital devices and servers, leading to inadequate service data quantity and quality, particularly in providing enhanced user experiences like EPG and channel browsing services.
Innovation Solution
A digital system that processes service data by transmitting device information and location data between connected devices, using Uniform Resource Locators (URLs) for thumbnail images, and employing encryption and authentication to enhance service data management and distribution, thereby increasing service coverage and quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If digital broadcasting systems use traditional service data transmission methods, then system simplicity is maintained, but service coverage and data quality are limited
Solution Approach 1:
The patent combines service data from multiple digital devices (first device, second device, third device) into a unified service guide system. The server aggregates EPG data, channel information, and service metadata from different sources, merging them into comprehensive service guides that expand coverage beyond what individual devices could provide alone.
Solution Approach 2:
The service guide system is designed to handle multiple types of service data simultaneously (EPG, channel browsing, service information) and serve multiple device types (set-top boxes, mobile devices, PCs). The system provides universal access to service data through various transmission protocols and interfaces, making it adaptable to different platforms and use cases.
2Quantity of substance
If service data is transmitted between multiple digital devices and servers, then service data quantity and quality improve, but data exchange reliability becomes challenging
Solution Approach 1:
The patent implements feedback mechanisms where receiving devices send acknowledgment signals back to transmitting devices to confirm successful data reception. The server monitors data transmission status and requests retransmission of lost or corrupted service data packets, ensuring reliable delivery of EPG and service information across the network.
Solution Approach 2:
The system employs error correction codes and data redundancy techniques before transmission. Service data is encoded with checksums and parity bits that allow automatic detection and correction of transmission errors. Critical service information is replicated across multiple servers or storage locations to provide backup in case of data loss.
3Adaptability or versatility
If device information and location data are transmitted between devices, then service personalization improves, but information security risks increase
Solution Approach 1:
The patent applies different security measures to different types of information based on their sensitivity. Device identification data uses authentication protocols, while user profile information uses encryption. Location data is processed to provide service personalization without exposing precise geographic coordinates. Each data type receives security treatment appropriate to its specific requirements.
Solution Approach 2:
The server acts as an intermediary that receives, processes, and manages device information and service data. Instead of devices directly exchanging sensitive information, they communicate through the server which implements security policies, authentication mechanisms, and data protection measures. This intermediary layer isolates devices from each other while maintaining secure information exchange.
