Meta Information Reference ID for Selective Broadcast Data Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing content service systems send all meta information related to main contents, such as broadcast programs, to reception devices, making it impossible for devices to selectively receive only needed information and preventing changes to meta information during live broadcasts.
Innovation Solution
An information access system that includes an identification information transmission section to send a meta information reference ID, allowing reception devices to selectively acquire target meta information based on the ID, and a meta information extraction section to extract only necessary meta information, improving communication efficiency and enabling real-time updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all meta information is collectively sent to reception devices, then complete information is provided, but communication efficiency deteriorates and unnecessary data transfer increases
Solution Approach 1:
The patent segments meta information into multiple categories (e.g., program information, service information, advertisement information) and enables reception devices to selectively receive only the segments they need based on their functionality and user preferences, rather than receiving all meta information collectively
Solution Approach 2:
The patent extracts and transmits only the necessary portions of meta information that are relevant to the reception device's capabilities and user needs, separating essential information from unnecessary data to reduce communication overhead
2Loss of information
If all meta information is sent together, then information completeness is maintained, but the ability to update meta information during broadcast deteriorates
Solution Approach 1:
The patent implements periodic transmission of meta information in structured segments, allowing the transmitting device to update specific segments independently during broadcast without requiring complete retransmission, thereby enabling real-time updates while maintaining information completeness
Solution Approach 2:
The patent creates a dynamic meta information transmission system where the composition and content of meta information segments can be adjusted in real-time based on broadcast requirements, allowing flexible updates during the broadcast process
3Loss of information
If complete meta information is transmitted, then all possible content is available, but device complexity and processing load increase
Solution Approach 1:
The patent applies local quality by tailoring the meta information transmission to each reception device's specific capabilities and needs, providing different devices with different subsets of meta information appropriate to their function, thereby reducing processing complexity while maintaining necessary information availability

AI summary
An information search system is provided. The information search system is capable of searching a target content based on meta information provided by a broadcast station, in which a reception device makes an inquiry toward a directory service server based on a meta information reference ID accompanying meta information coming from the broadcast station so that a meta information group is derived for reference by the meta information reference ID. Also, another inquiry is made toward a content service server based on address information or a keyword of the content included in sub meta information in the meta information group so as to perform a search for any desired content.
