Screenshot Encoding with Embedded Program Metadata for Seamless Content Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current IPTV technologies lack an efficient method for encoding and sharing screenshots of playing programs, which hinders seamless content switching and sharing across devices.
Innovation Solution
A method and device for encoding a captured screenshot by embedding program information data into the image data frame, allowing for local storage or network sharing, and enabling direct content switching on electronic devices based on the extracted information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual tuning is used to switch programs, then device complexity is reduced, but user experience deteriorates due to time delays and manual effort
Solution Approach 1:
The system performs preliminary actions by capturing screenshots and embedding program information data in advance. When a user wants to switch programs, the device already has the program information ready in the screenshot metadata, eliminating the need for manual tuning and reducing time delays.
Solution Approach 2:
The patent introduces an intermediary mechanism - the embedded program information data within screenshot metadata - that mediates between the user's viewing experience and the program switching function. This intermediary allows automatic program identification and switching without direct user interaction with tuning controls.
2Adaptability or versatility
If screenshot encoding with embedded program information is implemented, then content sharing capability is improved, but device complexity increases due to encoding and data embedding requirements
Solution Approach 1:
The patent merges the screenshot image data with program information metadata into a single integrated file structure. The program information is embedded within the screenshot file itself, combining visual content and data information into one versatile format that can be shared and processed together.
Solution Approach 2:
The embedded screenshot format serves multiple functions: it acts as both a visual record of the program being viewed and a data carrier containing program information for switching and sharing. This multi-functional approach enables both content sharing and program switching capabilities without requiring separate systems.
3Loss of information
If program information is embedded in screenshot metadata, then information retention is improved, but data processing complexity increases
Solution Approach 1:
The patent implements a nested structure where program information metadata is embedded within the screenshot file format. The metadata is contained within the image file structure itself, allowing the information to be retained with the visual content while enabling systematic extraction when needed.
Data Source
AI summary
A method and device for encoding a captured screenshot and controlling program switching on an electronic device based on the captured screenshot. The method includes the electronic device performing: capturing from a display a screenshot of a playing program or display content with a stored image data frame; encoding the image data frame of the screenshot, afterwards storing the encoded image data frame of the screenshot; retrieving program information data of the screenshot from a program database; embedding retrieved program information data of the captured screenshot into the encoded image data frame to form an embedded encoded image file. The embedded encoded image file enables the first electronic device or a second electronic device to directly switching to start playing the program or displaying the content on the electronic device according to the captured screenshot.
