Display Apparatus Channel Map Update via Server Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in changing channels by voice command due to errors in channel maps provided by content providers, such as omitted channel numbers, improper mappings, or changed channel names, which can't be easily checked across all regions offering voice services, especially when channel maps from different companies vary.
Innovation Solution
A method and apparatus for acquiring and updating channel information, involving user input to select a channel, acquiring channel numbers, source IDs, and channel names, and transmitting these to a server for updating the channel map, which includes comparing and updating aliases based on retrieved channel information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If channel maps are provided by content providers and stored in search servers, then channel information can be obtained for voice-based channel changing, but errors in channel maps (omitted channel numbers, improper mappings, changed channel names) cannot be easily detected or corrected across all regions
Solution Approach 1:
The patent implements a feedback mechanism where display apparatuses transmit actual channel information (channel numbers, source IDs, channel names) to a server, which then updates the channel maps stored in search servers. This closed-loop feedback system allows errors in channel maps to be detected and corrected by comparing provider-provided information with actual channel data from multiple regions, resolving the contradiction between maintaining accurate channel maps and the difficulty of detecting errors across distributed regions.
2Adaptability or versatility
If channel maps from different companies are used, then various TV program information can be provided, but it becomes difficult to secure an exact channel map due to variations between company channel maps
Solution Approach 1:
The patent merges channel information from multiple display apparatuses belonging to different companies into a unified channel map maintained by the server. By collecting and integrating channel data (channel numbers, source IDs, channel names) from various sources, the system creates a consolidated channel map that maintains consistency across different companies while supporting diverse TV program information, thus resolving the contradiction between multi-company adaptability and channel map consistency.
3Ease of operation
If voice recognition is used to obtain channel names for channel changing, then users can control channel switching by uttering channel names, but the system fails when channel map errors exist
Solution Approach 1:
The patent performs preliminary actions by continuously collecting and updating channel information from multiple display apparatuses before voice commands are executed. The server proactively maintains an updated channel map with accurate channel numbers, source IDs, and channel names by receiving data from various regions and companies. This preliminary updating ensures that when users issue voice commands for channel changing, the system references accurate, pre-verified channel information, thereby maintaining both ease of voice-based operation and reliability of channel changing accuracy.
Data Source
AI summary
A display apparatus includes an input interface that receives a user input for selecting a channel, a tuner that receives a broadcast signal corresponding to the channel, a display that displays a content included in the broadcast signal, a storage configured to store channel information obtained from the broadcast signal, a communicator configured to communicate with an external apparatus, and a controller that selects a channel based on the user input, displays content corresponding to the changed channel on the display, acquires a channel number, a source ID and a channel name with respect to the channel, and transmits the channel number, the source ID and the channel name to a server.
