Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing smart TV screenshot methods capture full screen images, including unwanted system notification information such as volume bars, resulting in excessive content in the screenshot.

Innovation Solution

The method involves acquiring a layer range of On Screen Display (OSD) sub-layers corresponding to application windows and generating a screenshot by snapping the OSD sub-layers in that range, allowing for selective capture of application windows without system notifications, using a processor to determine layer attributes and superpose images if necessary.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If full screen snapshot is taken to capture all displayed information, then complete screen content is recorded, but unwanted system notification information such as volume bars is included

Engineering Contradiction:

Improvecompleteness of screenshot contentVSAvoidunwanted system notification information

Core Design Contradiction:

Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The display screen is divided into multiple layers including signal layer and OSD layer, with the OSD layer further segmented into multiple sub-layers. This segmentation allows selective capture of specific sub-layers containing application windows while excluding sub-layers containing system notifications, thus resolving the contradiction between capturing complete information and excluding unwanted content.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent extracts and identifies specific OSD sub-layers that contain application window information while excluding sub-layers containing system notification information. By taking out only the relevant sub-layers for screenshot capture, the solution achieves complete capture of application content while eliminating unwanted system notifications.

Inventive Principle:

Principle #2Taking out (Extraction)

2Quantity of substance

If full screen snapshot is taken, then all content is captured, but the screenshot contains excessive content including system notifications

Engineering Contradiction:

Improveamount of screenshot contentVSAvoidexcessive unwanted content

Core Design Contradiction:

Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The patent extracts only the necessary OSD sub-layers containing application windows for screenshot capture, excluding sub-layers with system notifications. This extraction approach reduces the quantity of screenshot content to only what is necessary, eliminating excessive unwanted content while preserving all relevant application information.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

This application provides a TV screenshot method and an associated television (TV). The method includes: upon receiving a screenshot request, acquiring a layer range of On Screen Display (OSD) sub-layers corresponding to windows of every application displayed on an OSD layer; and generating the screenshot image by taking a snap shot of the OSD sub-layers in the layer range. This application can prevent unwanted system notification information image from being captured when a snap shot is taken.
