Screen Projection Voice Overlay to Avoid Encoder Reset Delays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Frequent wake-up of voice applications in smart rearview mirrors during screen projection leads to significant delays in image display on vehicle machine screens, affecting user interaction experience due to the need for encoder resetting and switching between applications.
Innovation Solution
The method involves adding to-be-displayed content of the voice application to the page of a currently running non-voice application, thereby avoiding the need for switching applications and resetting the encoder, thus reducing delays by projecting the combined content directly onto the screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the voice application is frequently waked up during screen projection, then the voice interaction function is improved, but the screen projection delay increases significantly
Solution Approach 1:
The patent merges the voice application content with the current projected application page by adding the voice application's to-be-displayed content to the existing first page. This combination allows the voice interaction functionality to be implemented without switching to a separate voice application page, thereby maintaining the encoder's continuous operation and avoiding projection delays.
2Adaptability or versatility
If the application page is switched to the voice application page, then the voice interaction is enabled, but the encoder needs to be reset causing display delay
Solution Approach 1:
The patent performs preliminary action by pre-adding the voice application's to-be-displayed content to the first page before projection. This preparation ensures that when voice interaction is needed, the content is already integrated into the projected page structure, eliminating the need for encoder resetting and application switching.
3Productivity
If the voice application content is added to the first page, then the application switching is avoided, but the page structure becomes more complex
Solution Approach 1:
The patent segments the page content by separating the voice application's to-be-displayed content from other applications' content. This segmentation allows the voice content to be independently managed and added to the first page without affecting the overall system architecture or requiring complex integration of multiple application structures.

AI summary
The present application discloses a method and apparatus for controlling display in a screen projection scenario, a device, a medium and a program product, relating to the technical fields of autonomous driving, Internet of Vehicles, intelligent voice, and screen projection in artificial intelligence. The specific implementation is: receiving a voice interaction instruction corresponding to a voice application; if a first page corresponding to a first application in at least one non-voice application has been projected onto a screen of a terminal device, adding to-be-displayed content corresponding to the voice application to the first page to obtain a to-be-projected page corresponding to the first application; and projecting the to-be-projected page onto the screen of the terminal device. The above process can reduce a delay in displaying an image projected on the screen.
