Unified Program Guide for Digital Broadcasting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing receiving apparatuses for digital broadcasting from multiple transmission media suffer from poor user operability due to duplicate displays of same channels when receiving IP retransmission and RF direct reception, leading to inefficient program searching.
Innovation Solution
A receiving apparatus that extracts and integrates program information from both IP retransmission and RF direct reception, comparing network IDs, TS-IDs, or service IDs to eliminate duplicate channel listings, creating a unified program guide for improved user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If program information from multiple transmission media is simply integrated and displayed, then the quantity of program information increases, but duplicate channel listings occur reducing user operability
Solution Approach 1:
The patent extracts duplicate program information from the integrated data set by comparing channel identifiers (service IDs, network IDs, TS IDs) across different transmission media. The duplicate removal unit identifies and eliminates redundant channel listings while preserving unique channels, thereby maintaining information quantity while improving user operability.
Solution Approach 2:
The patent changes the parameter of program information by adding identification parameters (service ID, network ID, TS ID) that enable differentiation and comparison of channels across transmission media. This parameter enhancement allows the system to recognize duplicates and integrate information effectively without redundancy.
2Device complexity
If EPG is displayed separately for each transmission media, then the information structure remains simple, but program searching efficiency deteriorates
Solution Approach 1:
The patent merges EPG information from multiple transmission media into a unified program guide display. The integration unit combines program information while the duplicate removal unit eliminates redundancies, creating a single consolidated EPG that allows users to search across all transmission media simultaneously, significantly reducing program searching time.
3Ease of operation
If duplicate channel listings are removed by comparing all program information, then user operability improves, but processing complexity increases
Solution Approach 1:
The patent replaces complex manual comparison processes with automated electronic identification and comparison systems. By using standardized identifiers (service ID, network ID, TS ID) and automated duplicate removal algorithms, the system efficiently processes program information without requiring complex manual intervention, thus improving operability while managing processing complexity.

AI summary
The present invention provides an easy-to-search program guide having efficient display contents of program information when receiving digital broadcasting from plural transmission media. A program information extracting unit extracts program information for channels receivable from a first and a second transmission media, and stores the extracted program information of individual channels in a storing unit. A program information integrating unit, when integrating program information of the first transmission media and program information of the second transmission media, compares program information stored in the storing unit, and integrates duplicate program information of a same channel, if any, into one piece of program information. A display contents creating unit creates a program guide based on the integrated program information, and displays it in a display unit.
