Television Screen Control Background Plane Advertising
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital television systems require several seconds for channel zapping due to the need to wait for an i-frame of the new channel to be transmitted, making it challenging to display advertisements during this time without disrupting the broadcasting screen.
Innovation Solution
A television screen control apparatus and system that displays advertisements on a background plane while the new channel is loading, using a broadcasting contents data processing unit, a channel zapping advertisement processing unit, and a screen mixing unit to combine and manage the advertisement and broadcasting content images, allowing the advertisement to be shown from the moment the channel change is initiated until the new channel is displayed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If advertisement is displayed on the video plane during channel zapping, then advertisement visibility is improved, but it disrupts the broadcasting screen and creates visual interference
Solution Approach 1:
The patent introduces a depth dimension by implementing multiple display planes (video plane and background plane) instead of displaying content on a single 2D screen. The advertisement is placed on the background plane which is visually positioned behind the video plane, allowing simultaneous display of both broadcasting content and advertisement without visual interference through depth-based layering
2Loss of information
If advertisement is displayed on the background plane during channel zapping, then advertisement exposure is improved, but the advertisement cannot be shown when broadcasting content is present
Solution Approach 1:
The patent pre-loads advertisement content onto the background plane before channel zapping occurs. When channel switching is initiated, the advertisement is already positioned and ready to be immediately visible on the background plane, eliminating the need for real-time advertisement switching and ensuring continuous advertisement exposure throughout the channel zapping process
3Speed
If channel zapping time is reduced by optimizing i-frame transmission, then channel switching speed is improved, but advertisement display opportunities are reduced
Solution Approach 1:
The patent ensures continuous advertisement display by utilizing the background plane that remains visible throughout the entire channel zapping process. While the video plane transitions between channels, the background plane continuously displays the advertisement, maximizing advertisement exposure duration without interfering with channel switching speed optimizations

AI summary
A television screen control apparatus includes a broadcasting contents data processing unit receiving broadcasting content for a new channel in response to an channel changing input signal. When broadcasting content is not displayed during a channel transition period, advertising information on a background plane is visible to a viewer.
