Multimedia DNA Grouping for Real-Time TV User Clustering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies do not effectively group users viewing the same TV broadcast, as they lack a method to collect and analyze user information in real time, making it difficult to provide communication services between viewers of the same channel.
Innovation Solution
A system that uses multimedia DNA to group users by comparing broadcasting signals from TVs in real time, with a server that receives DNA information, calculates similarity, and transmits group information to each TV, allowing users to communicate and determine channel changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the server collects and analyzes DNA information from all TVs to group users, then user grouping accuracy is improved, but server load increases
Solution Approach 1:
The patent applies preliminary action by having each TV device generate its own standard DNA information for the currently viewed broadcast before transmission. This pre-processing at the client side reduces the computational burden on the server, as the server only needs to receive and compare pre-generated DNA strings rather than analyzing raw broadcast signals from all devices.
Solution Approach 2:
The system implements self-service by enabling TV devices to autonomously generate their DNA information and perform initial grouping comparisons. Each TV independently determines whether its current broadcast matches existing groups by comparing its generated DNA against group standard DNA, reducing the need for centralized server processing of every device's data.
2Speed
If the system transmits DNA information from all TVs to the server, then real-time grouping is achieved, but network bandwidth consumption increases
Solution Approach 1:
The patent extracts only the essential DNA information (compact string representation) from each TV's broadcast signal for transmission to the server, rather than transmitting the entire raw broadcast data. This extraction of key identifying features enables real-time grouping while minimizing network bandwidth consumption.
Solution Approach 2:
The system uses DNA information as a simplified copy or representation of the actual broadcast content. Instead of transmitting and processing full broadcast signals, the patent transmits compact DNA strings that serve as unique identifiers, enabling efficient comparison and grouping with minimal network overhead.
3Measurement precision
If the server processes DNA information from every TV individually, then grouping accuracy is maintained, but processing time increases
Solution Approach 1:
The patent segments the grouping process into two parts: (1) Each TV independently generates its own DNA information for the current broadcast, and (2) The server receives these pre-generated DNA strings and performs simple comparison operations. This segmentation transforms a complex centralized processing task into distributed client-side computation with simple server-side matching, reducing overall processing time while maintaining accuracy.
Data Source
AI summary
A system of grouping broadcasting signals based on a multimedia DNA of corresponding broadcast, which groups users viewing the same broadcast through the multimedia DNA of each broadcasting signal output from a TV in real time. A DNA information receiver receives DNA information on broadcasting signals, which are broadcasted through each TV. A DNA information grouping unit calculates similarity of the DNA information received through the DNA information receiver, and when the calculated similarity satisfies a predetermined similar condition, determines the similar DNA information as the DNA information of the same broadcasting signal to group the DNA information into the same group. A group information transmitter transmits group related information of each group grouped by the DNA information grouping unit to each TV.
