Image Display Apparatus Background Channel Search Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image display apparatuses require users to wait for channel searches to complete during initial setting operations, which prolongs the setup time and hinders simultaneous performance of other initial settings.
Innovation Solution
The apparatus performs a first channel search to extract valid frequencies and a second channel search for valid channels as background operations, allowing these searches to run in parallel with initial setting operations, thereby reducing setup time and enabling other settings to proceed without waiting for channel search completion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If channel search is performed during initial setting operations, then channel search function is achieved, but initial setting time is prolonged
Solution Approach 1:
The patent performs a first channel search to extract valid frequencies before the actual channel search is executed. This preliminary action prepares the frequency information in advance, allowing the subsequent channel search to proceed more efficiently without delaying other initial setting operations.
Solution Approach 2:
The channel search process is divided into two separate searches: a first channel search that extracts valid frequencies, and a second channel search that searches for valid channels among those frequencies. This segmentation allows the frequency extraction to be completed independently, reducing the overall impact on initial setting time.
2Measurement precision
If channel search is performed sequentially during initial setting, then accurate channel information is obtained, but other initial setting operations are delayed
Solution Approach 1:
The first channel search extracts valid frequencies in advance, preparing the necessary information before the actual channel search. This preliminary frequency extraction enables the second channel search to focus only on valid frequencies, maintaining accuracy while allowing other initial setting operations to proceed in parallel.
Solution Approach 2:
The patent extracts valid frequencies from the channel search process and separates this extraction step from the main channel search execution. By taking out the frequency extraction as a preliminary step, the system maintains channel information accuracy while enabling parallel execution of other initial setting operations.

AI summary
Provided are an image display apparatus and an operation method thereof. The image display apparatus includes a display, a memory, and a processor configured to execute instructions stored in the memory, the instructions, when executed by the processor, cause the image display apparatus to perform a first channel search comprising searching for one or more channels in which a signal exists as a background operation, while simultaneously performing at least one of initial setting operations of the image display apparatus, to perform a channel search condition setting operation, in response to the channel search condition, to perform a second channel search comprising searching for at least one channel receivable by the image display apparatus from among the channels obtained by the first channel search, based on the obtained channel search condition, and display a result of the second channel search on the display.
