Video File Search Using EPG Metadata for Automatic Content Collation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current connected TVs require manual keyword input for searching video files, leading to inconvenient and often poor search results due to the lack of integration between digital TV programs and network videos, and the need for users to access video files through computer-like operation interfaces.
Innovation Solution
A method and system for searching and collating video files using semantic keywords, which includes retrieving metadata, parsing video titles, and grouping matched files into video channels, allowing for automatic selection and organization of video content without manual input, utilizing a video semantic searching and collating process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual keyword input is used for searching video files, then users can access video platforms, but the operation becomes inconvenient and search results become poor
Solution Approach 1:
The system automatically retrieves program information from digital TV signals and uses it to search for video files without requiring manual user input. The television device itself performs the searching and matching operations, making the system self-serving rather than requiring continuous user intervention.
Solution Approach 2:
The system pre-retrieves program information including titles, episode numbers, and other metadata from digital TV broadcasts before the user needs to watch the content. This preliminary extraction and storage of structured information enables automatic searching without manual keyword input.
2Adaptability or versatility
If digital TV signals and network videos remain separate, then existing systems can maintain simplicity, but integration and automatic searching cannot be achieved
Solution Approach 1:
The system merges digital TV signal processing with network video searching by using program information from digital broadcasts as the basis for searching video files on network platforms. This combines two previously separate functions into an integrated system that handles both signal sources uniformly.
Solution Approach 2:
The television device is designed to handle multiple signal sources (digital TV and network videos) through a unified interface and processing mechanism. The same program information extraction and searching methodology is applied regardless of whether the source is digital broadcast or network platform.
3Ease of operation
If computer-like operation interfaces are used on connected TVs, then network video platforms can be accessed, but the viewing experience loses TV-like convenience
Solution Approach 1:
The system automatically performs the entire searching and matching process without requiring user interaction. Program information is automatically extracted from digital TV signals, used to search network video platforms, and results are presented to the user without manual keyword input or navigation through computer-like interfaces.
Solution Approach 2:
The manual mechanical interaction of typing keywords and navigating through search results is replaced by an automated information processing system. The television device automatically retrieves program information, processes it through semantic analysis, and retrieves video files without requiring physical user input operations.
Data Source
AI summary
The disclosure introduces a method and a system of searching and collating video files, a method for establishing a semantic group, and a program storage medium therefor. In the method of searching and collating video files, program information in an electronic program guide (EPG) may be used for searching matching candidate video files, and titles of the candidate video files are reformatted or amended for selection. Some of the candidate video files are integrated to be a complete program, and these candidate video files may be grouped into a channel set for users to watch.
