Display Apparatus Channel Search Skipping Redundant Frequencies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current channel search methods for display apparatuses, such as smart TVs, are inefficient as they require searching each frequency multiple times to set TV channels and frequencies, significantly reducing user experience due to prolonged search times.
Innovation Solution
A method and apparatus that first perform channel search based on a list of frequencies to identify and mark channels of one broadcast version, then skip these marked frequencies during a subsequent search for another broadcast version, thereby reducing redundant searches and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If channel search is performed by searching each frequency multiple times to ensure comprehensive channel detection, then the reliability of channel search is improved, but the time required for channel search increases significantly
Solution Approach 1:
The patent segments the channel search process into two distinct phases: a first channel search that searches all frequencies without skipping, and a second channel search that skips frequencies already searched in the first phase. This segmentation allows the system to maintain comprehensive channel detection while reducing redundant searches, thereby resolving the contradiction between reliability and time consumption.
Solution Approach 2:
The patent performs a preliminary channel search (first channel search) before the main channel search (second channel search). During this preliminary action, the system records which frequencies have been searched and stores this information in a skip list. This preliminary action enables the second channel search to skip already-searched frequencies, ensuring comprehensive detection while reducing overall search time.
2Reliability
If channel search searches all frequencies to ensure no channels are missed, then the completeness of channel search is improved, but the productivity of the channel search process decreases
Solution Approach 1:
The patent divides the channel search into two segments: a first channel search that comprehensively searches all frequencies to ensure no channels are missed, and a second channel search that uses a skip list to avoid redundant frequency searches. This segmentation maintains completeness while improving efficiency by eliminating duplicate searches.
Solution Approach 2:
The first channel search serves as a preliminary action that identifies and records all frequencies containing channels. This preliminary search enables the second channel search to skip these recorded frequencies, ensuring completeness is achieved in the first phase while productivity is improved in the second phase through reduced searching.
3Reliability
If the channel search operation searches each frequency multiple times to ensure accurate channel and frequency setting, then the reliability of channel configuration is improved, but the user experience deteriorates due to prolonged search time
Solution Approach 1:
The patent segments the channel search into two phases: a first channel search that ensures accurate channel configuration by searching all frequencies, and a second channel search that skips already-searched frequencies using a skip list. This segmentation maintains configuration accuracy while reducing the time users wait, thereby improving user experience.
Solution Approach 2:
The first channel search performs a preliminary comprehensive search to accurately identify all channels and their frequencies. This preliminary action stores the search results in a skip list, enabling the second channel search to skip redundant frequencies. This ensures accurate channel configuration is achieved in the first phase while reducing overall search time and improving user experience in the second phase.

AI summary
Disclosed in the present application are a method for channel searching and a display apparatus. The method can include: in response to a channel search instruction, obtaining a frequency of a channel to be searched in a first list of frequencies, and performing channel search to obtain a first-type broadcast channel; skipping one or more frequencies corresponding to the first-type broadcast channel, and performing channel search based on remaining frequencies in the first list of frequencies to obtain a second-type broadcast channel.
