3D Display Apparatus Feedback Control for Duplicate Guidance Elimination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When a 3D display apparatus and a video signal reproduce apparatus are separated, the video signal reproduce apparatus cannot identify the 3D display method of the connected display device, leading to duplicate guidance for viewing 3D content, which can be confusing for users and requires unnecessary adjustments.
Innovation Solution
A video display system where the 3D display apparatus transmits messages to the video signal reproduce apparatus to control the reproduction and display of 3D content, including messages to stop or start reproduction and to prompt user preparation for 3D viewing, ensuring appropriate guidance is provided only when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the video signal reproduce apparatus provides guidance for viewing 3D content, then the user is informed about viewing requirements, but duplicate guidance appears on both the reproduce apparatus and display apparatus making it difficult to see and requiring multiple adjustments
Solution Approach 1:
The display apparatus provides feedback to the reproduce apparatus about its 3D display capabilities and current state. The reproduce apparatus receives this feedback and adjusts its guidance output accordingly, stopping guidance when the display apparatus is ready and resuming when needed, thus avoiding duplicate guidance while ensuring information is communicated effectively
Solution Approach 2:
A message communication mechanism acts as an intermediary between the reproduce apparatus and display apparatus. Messages are exchanged to coordinate guidance display timing, allowing the reproduce apparatus to suppress its guidance output when the display apparatus is providing it, eliminating duplication while maintaining information flow
2Loss of information
If the reproduce apparatus displays guidance for 3D viewing preparation, then users are informed about viewing requirements, but users must conduct adjustment operations twice (once on reproduce apparatus and once on display apparatus)
Solution Approach 1:
The display apparatus communicates its readiness state back to the reproduce apparatus through feedback messages. When the display apparatus is ready to display 3D content, it sends a message to the reproduce apparatus to stop providing guidance and begin reproduction, eliminating redundant adjustment operations and saving user time
Solution Approach 2:
The display apparatus performs preliminary preparation for 3D display and communicates this state to the reproduce apparatus in advance. This allows the reproduce apparatus to preemptively stop its guidance display and prepare for content reproduction, coordinating actions to avoid duplicate user operations

AI summary
A video display system, having a reproduce apparatus, which is configured to reproduce content, thereby to output, and a display apparatus, which is configured to display the content outputted from the reproduce apparatus, wherein said display apparatus, when being inputted therein a 3D content, including the 3D video therein, is inputted from the reproduce apparatus, transmits a message for stopping reproduction of the 3D content and a message for suppressing the output of the message for prompting the preparation of the viewing/listening of the 3D video, to the reproduce apparatus, and presents the message for prompting the preparation of the viewing/listening of the 3D video, when receiving an instruction of reproducing the 3D content from a user, transmits a message for reproducing the 3D content to the reproduce apparatus, and is the reproduce apparatus, when receiving the message for stopping the reproduction of the 3D content, stops the reproduction of the 3D content, and when receiving the message for reproducing the 3D content, reproduces the 3D content, without outputting the message for prompting the preparation of the viewing/listening of the 3D video, and thereby to output, whereby the video signal reproduce apparatus to be connected with display apparatuses of various kinds of display methods starts reproducing of the 3D content, while preventing a display for confirming completion of preparation for viewing/listening of a user from being outputted in duplicate or by a plural number of times.
