Client Apparatus XML Metadata Service Discovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital TV services, such as IPTV, face challenges in providing users with an efficient way to search and access various content services from multiple providers, as current systems lack a standardized method for metadata-based service discovery and user interface customization.
Innovation Solution
A client apparatus that receives services from an outside server, featuring a network interface for XML metadata reception and a controller to produce a UI skin based on this metadata, enabling users to easily search and access services from multiple content providers by converting services into XML format and displaying a customized user interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple content providers offer diverse services, then service variety increases, but service discovery difficulty increases
Solution Approach 1:
The patent introduces a standardized metadata system as an intermediary between multiple content providers and users. This metadata includes unified service information, provider identifiers, and descriptive attributes that enable systematic organization and searching of services from different providers without requiring users to navigate each provider's unique interface separately
Solution Approach 2:
The patent transforms service information into standardized metadata parameters that can be systematically searched and filtered. By converting diverse service descriptions into uniform data structures with consistent fields and formats, the system enables efficient service discovery across multiple providers through parameter-based querying
2Adaptability or versatility
If each content provider uses its own interface format, then provider autonomy is maintained, but user interface complexity increases
Solution Approach 1:
The patent creates a universal metadata framework that works across multiple content providers while preserving their individual service characteristics. The standardized metadata structure serves as a common interface layer that handles provider autonomy internally while presenting a unified view to users, eliminating the need for users to adapt to multiple different interface formats
3Adaptability or versatility
If service information is provided in non-standardized formats, then provider flexibility is maintained, but search efficiency decreases
Solution Approach 1:
The patent converts flexible, non-standardized service information into standardized metadata parameters that maintain provider flexibility through configurable fields while enabling efficient searching. The standardized parameter structure allows for consistent indexing, filtering, and querying operations that significantly improve search efficiency compared to unstructured formats

AI summary
A service providing method providing at least one of service provided from a plurality of contents provider to clients includes receiving metadata related to at least one of service provided from the contents provider; converting the received metadata into the metadata of XML format; and providing the metadata of the XML format to the clients.
