Electronic Device RF Buffering for Multi-View Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices experience screen disconnection issues when switching between single-view and multi-view modes due to differences in content sources, leading to disrupted viewing experiences.
Innovation Solution
An electronic device that stores a radio frequency (RF) signal in a buffer during multi-view mode and uses this buffer to synchronize content reproduction positions when switching to single-view mode, ensuring seamless transitions by matching reproduction times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display device switches from single-view mode to multi-view mode using different content sources (RF signal to IP streaming signal), then the user can access multiple content streams simultaneously, but screen disconnection and viewing disruption occur during the transition
Solution Approach 1:
The system performs preliminary actions by storing RF signals in a buffer before switching to IP streaming signals during multi-view mode. When returning to single-view mode, the buffer contains pre-captured RF signals that can be replayed to maintain seamless transition. This preliminary buffering action ensures that content reproduction can continue without interruption during mode switching.
Solution Approach 2:
The buffer acts as an intermediary component between the RF signal source and the display output. During mode transitions, the buffer mediates the switch by providing a temporary storage zone that decouples the two different content sources (RF and IP streaming), allowing the system to transition between single-view and multi-view modes without direct conflict between the different signal sources.
2Reliability
If the system stores RF signals in a buffer during multi-view mode to enable seamless switching back to single-view mode, then screen continuity is maintained, but additional memory resources and buffering complexity are required
Solution Approach 1:
The buffer serves multiple functions: it stores RF signals during multi-view mode for later replay, acts as a transition mediator during mode switching, and provides a fallback content source. This multi-functionality reduces the need for separate dedicated components for each function, thereby managing complexity while maintaining reliability.
3Reliability
If the system synchronizes reproduction time information between IP streaming signals and buffered RF signals during mode switching, then seamless content transition is achieved, but additional processing time and computational resources are required
Solution Approach 1:
The system performs preliminary synchronization by capturing and storing reproduction time information along with the RF signals in the buffer during multi-view mode. When switching back to single-view mode, this pre-captured time information is immediately available for comparison and synchronization, eliminating the need for time-consuming real-time alignment calculations during the actual mode transition.

AI summary
An electronic device including a memory; and a processor configured to: identify whether a multi-view switch to switch from a single view to multi-views occurs; based on the multi-view switch occurring, receive a radio frequency (RF) signal corresponding to content displayed in the single view and store the RF signal in a buffer, while displaying, through the plurality of screens, content based on an Internet protocol (IP) streaming signal; based on a single-view switch to switch from the multi-views to the single view, identify reproduction time information of the IP streaming signal at a time point at which the single-view switch occurs; and identify a reproduction position having same reproduction time information as the identified reproduction time information of the IP streaming signal in the RF signal stored in the buffer, and display, in the single view, the content based on the RF signal from the identified reproduction position.
