Broadcasting Receiver Entropy Channel Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of broadcasting devices often lack real-time access to relevant information corresponding to broadcasting content, and existing devices do not efficiently provide such information, especially when the broadcasting program is not identified or when data traffic with matching servers is high, particularly for live or unpredictable signals.
Innovation Solution
A broadcasting receiving apparatus that accesses a network to receive broadcasting signals, identifies channel changes by calculating entropy, generates fingerprints, and retrieves relevant information from matching servers, reducing data traffic by only communicating when channel changes occur, and continuously updates information in real-time for live broadcasts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the device continuously communicates with the matching server to identify broadcasting programs, then relevant information can be provided, but data traffic increases and server operational costs increase
Solution Approach 1:
The patent applies preliminary action by pre-identifying channel changes using entropy calculation before attempting program identification. The system calculates entropy of image frames to detect channel transitions, and only then communicates with the matching server to identify programs. This preliminary detection mechanism prevents unnecessary continuous communication, reducing data traffic while ensuring relevant information is provided only when needed.
2Ease of operation
If the device uses web surfing to obtain information about broadcasting contents, then users can access relevant information, but the information is not synchronized with current broadcasting content and is limited to what the user is aware of
Solution Approach 1:
The patent implements feedback by establishing a continuous loop where the system monitors broadcasting signals, identifies channel changes through entropy calculation, retrieves program identification information from the matching server, and provides relevant information to users in real-time. This automated feedback mechanism ensures information is always synchronized with current broadcasting content without requiring user intervention or web surfing, solving both the ease of access and real-time synchronization problems.
3Loss of energy
If the device calculates entropy of image frames to identify channel changes, then data traffic with matching server is reduced, but processing complexity increases
Solution Approach 1:
The patent applies self-service by enabling the device to autonomously detect channel changes through entropy calculation of image frames without external assistance. The system independently monitors broadcasting signals, calculates entropy to identify channel transitions, and only then engages the matching server for program identification. This self-service capability reduces data traffic while the processing complexity is managed through efficient entropy algorithms that operate locally on captured frames.

AI summary
A broadcasting receiving apparatus and a method for providing broadcasting signal relation information are provided. The broadcasting receiving apparatus, which accesses a server through a network, includes a broadcasting signal receiver which receives a broadcasting signal; a channel identifier which identifies a change of a channel of the broadcasting signal, generates a fingerprint corresponding to the broadcasting signal of the changed channel, and receives identification information of the changed channel from a matching server based on the generated fingerprint; and a relevant information provider which receives conditional information that indicates a condition for receiving relevant information of the broadcasting signal if the channel is changed, receives the relevant information based on the conditional information and displays the received relevant information.
