Broadcast Receiving Device Integrating Air and Internet EPG Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current broadcast receiving devices are limited in providing rich broadcast-related information as they rely on over-the-air interfaces, which restrict the capacity of information they can offer, and lack the ability to control image quality based on diverse network sources.
Innovation Solution
A broadcast receiving device that integrates data from both air interface-based and Internet-based electronic program guides (EPGs), allowing it to selectively search and merge information to provide richer content and adjust image quality according to genre and subgenre information received through various networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If only air interface-based EPGs are used, then the device complexity is low, but the quantity of broadcast-related information is limited
Solution Approach 1:
The patent merges air interface-based EPG data and Internet-based EPG data into a unified EPG database. The controller receives first EPG data through the broadcast network and second EPG data through the Internet, then integrates these multiple data sources to provide comprehensive broadcast-related information, thereby increasing the quantity of information without requiring completely separate systems.
Solution Approach 2:
The EPG database is designed to serve multiple functions: it stores broadcast schedule information, program descriptions, and additional broadcast-related information. The system can selectively search and provide information from either air interface or Internet sources depending on the specific information needed, making the EPG system universally applicable for various information retrieval needs.
2Quantity of substance
If multiple EPG sources are integrated, then the quantity of broadcast-related information increases, but the device complexity increases
Solution Approach 1:
The patent introduces an EPG database as an intermediary component between the multiple EPG data sources (air interface and Internet) and the application. The controller manages the integration of first EPG data and second EPG data into this unified database, which then serves as a single point of access for all broadcast-related information queries, simplifying the overall system architecture.
Solution Approach 2:
The system segments EPG data management into distinct components: receiving first EPG data through the broadcast network, receiving second EPG data through the Internet, processing and integrating these data sources, and storing them in a unified EPG database. This segmentation allows each component to be optimized independently while working together to provide comprehensive information.
3Reliability
If EPG data is processed from multiple networks, then the reliability of broadcast-related information improves, but the processing time increases
Solution Approach 1:
The patent implements preliminary action by pre-processing and pre-integrating first EPG data and second EPG data into the EPG database in advance. When an application requests broadcast-related information, the controller can selectively search the pre-integrated database without needing to process raw data from multiple networks in real-time, thereby reducing query response time while maintaining information reliability.
Solution Approach 2:
The system dynamically adjusts its data retrieval strategy based on the specific information request. The controller can selectively search either the air interface EPG data, the Internet EPG data, or both, depending on the type of information needed and the current network conditions. This dynamic approach optimizes processing time while ensuring reliable information delivery.
Data Source
AI summary
A broadcast receiving device is disclosed. The broadcast receiving device includes: a data storage unit; a communication unit configured to receive a first electronic program guide (EPG) through a broadcast network and to receive a second EPG through the Internet; and a controller. The controller may be configured to: process the first EPG to generate first broadcast-related information, process the second EPG to generate second broadcast-related information, make the first broadcast-related information and the second broadcast-related information into databases having different data structures and store the databases in the data storage unit. In addition, when a broadcast-related information request is received from an application being executed, the controller may selectively search a database corresponding to at least one of the first broadcast-related information and the second broadcast-related information to obtain requested broadcast-related information and to deliver the obtained broadcast-related information to the application.
