Unified Channel Table Generation for Multi-Format TV Receivers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During the transition from analog to digital television broadcasting, existing receivers struggle to maintain user-friendly channel sorting and require manual intervention to create unified channel lists, leading to user confusion and increased operational complexity.
Innovation Solution
A method and device that automatically generate a unified channel table by matching initial channel lists from multiple tuners, using sorting criteria like LCN codes and user preferences to ensure channels are positioned according to user expectations, eliminating the need for manual channel arrangement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a receiver is equipped with multiple tuners to receive both analog and digital television signals, then the receiver can maintain channel availability during the transition phase, but the channel list management becomes complex and requires manual intervention
Solution Approach 1:
The patent merges multiple separate channel lists (analog and digital) into a single unified channel list. The control unit automatically combines channels from both analog tuner and digital tuner into one integrated list, eliminating the need for manual management of separate lists and reducing operational complexity while maintaining the ability to receive multiple signal formats
Solution Approach 2:
The control unit performs preliminary automatic sorting and organization of channels into the unified list before the user needs to access them. By pre-organizing channels according to signal format and other criteria, the system eliminates the need for manual intervention when users need to access channels, resolving the complexity issue while maintaining versatility
2Ease of operation
If channels are sorted by transmission frequency in the unified channel list, then channel organization is simplified, but user expectations based on analog channel positions are not met
Solution Approach 1:
The patent applies different sorting criteria to different sections or groups of channels within the unified channel list. Analog channels may be positioned according to their traditional channel numbers to meet user expectations, while digital channels are organized separately or integrated in a way that maintains both user familiarity and technical accuracy, allowing local optimization for different channel types
Solution Approach 2:
The channel list sorting is made dynamic rather than static. The control unit can adapt the sorting order based on the detected signal formats and user preferences, allowing the channel positions to change automatically according to the received signals while maintaining user-friendly organization that meets expectations
3Manufacturing precision
If manual channel list creation is required for dual-tuner receivers, then precise channel positioning according to user preferences is achieved, but user effort and time consumption increase significantly
Solution Approach 1:
The control unit performs self-service by automatically generating and organizing the unified channel list without requiring manual user intervention. The system autonomously detects available channels from both analog and digital tuners, sorts them according to predefined criteria, and maintains the list automatically, achieving precise channel positioning while eliminating the time-consuming manual arrangement process
Solution Approach 2:
The control unit continuously monitors the channels received by both tuners and automatically updates the unified channel list based on feedback from the signal detection process. This automatic feedback mechanism ensures the channel list remains accurate and up-to-date without requiring manual intervention, resolving both the precision and time consumption issues

AI summary
The invention relates to a receiver and a method for automatically programming a receiver adapted to receive radio-television signals belonging to a plurality of radio- television networks in at least two different formats, the method comprising the steps of: storing into a first table (200) a first plurality of programs of said plurality of radio- television networks receivable by said receiver in a first signal format, associable with a first sorting criterion (95) of said first programs; storing into a second table (300) a second plurality of programs of said plurality of radio-television networks receivable by said receiver in a second signal format, associable with a second sorting criterion (100) of said second programs, including a step of storing into a third table (400) programs stored in said first (200) and second (300) tables based on existing matches between said first (95) and said second (100) sorting criteria.
