Multi-Viewpoint Video Integration for Bandwidth Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-viewpoint video distribution systems face challenges in efficiently transmitting and displaying videos from various viewpoints to multiple users, as they require significant communication bandwidth and complex system configurations, making it difficult to allow viewers to switch viewpoints in real-time.
Innovation Solution
The system generates and transmits an integrated video that combines multiple viewpoints into a single frame, allowing image display apparatuses to receive and display videos from different viewpoints as a single image, with user interfaces for changing viewpoints and playback speed, simplifying system configuration and reducing data transmission requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple viewpoint videos are transmitted separately to enable real-time viewpoint switching, then viewpoint flexibility is improved, but communication bandwidth requirements increase significantly
Solution Approach 1:
The patent combines multiple viewpoint videos into a single integrated video stream by spatially arranging different viewpoint images within one frame. This merging approach allows the receiver to display multiple viewpoints simultaneously while reducing the number of separate video streams that need to be transmitted, thereby decreasing communication bandwidth requirements while maintaining viewpoint flexibility.
Solution Approach 2:
The patent segments the single integrated video frame into multiple distinct viewpoint regions that can be independently accessed and displayed. By dividing the frame into separable viewpoint segments, the system enables selective display of different viewpoints without requiring separate video transmissions for each viewpoint, thus maintaining adaptability while reducing bandwidth consumption.
2Ease of operation
If separate video streams are used for each viewpoint to allow independent control, then user control flexibility is improved, but system complexity increases
Solution Approach 1:
The patent implements a universal control interface that can manipulate multiple viewpoints within a single video stream through unified controls. The playback control unit and viewpoint switching unit operate on the integrated video stream as a whole, providing multi-functional control capabilities without requiring separate control systems for each viewpoint, thereby reducing system complexity while maintaining user control flexibility.
Solution Approach 2:
The patent introduces an intermediary processing layer (the integrated video generation and control units) that mediates between the multiple viewpoint sources and the user interface. This intermediary structure consolidates control operations and simplifies the interface between viewpoints and users, reducing overall system complexity while preserving ease of operation.
3Measurement precision
If multiple independent video streams are transmitted for multi-viewpoint display, then viewpoint quality is maintained, but data transmission volume increases
Solution Approach 1:
The patent merges multiple viewpoint videos into a single integrated video stream where different viewpoints are arranged spatially within one frame. This combining approach maintains the quality of individual viewpoints while transmitting them as a unified stream, significantly reducing data transmission volume compared to sending separate full-resolution streams for each viewpoint.
Solution Approach 2:
The patent transitions from transmitting multiple separate video streams (temporal dimension) to arranging multiple viewpoints within a single spatial frame. By adding a spatial dimension to viewpoint presentation, the system maintains viewpoint quality and independence while reducing the number of transmission channels required, thereby decreasing overall data transmission volume.

AI summary
An image display method includes displaying an integrated video in which videos of a scene from different viewpoints are arranged in a frame, the videos including at least one real video and at least one virtual video generated from the at least one real video. A first user interface into which a first operation is input is displayed. Viewpoints of the displayed videos are changed according to the first operation. A second user interface into which a second operation is input is displayed. A playing speed of the displayed videos is changed according to the second operation.
