Solution Overview

Problem

When switching from a wide angle of view video to a partial video, users experience a sense of incongruity as they cannot recognize the positional relationship between the two videos, leading to a disjointed viewing experience.

Innovation Solution

The system displays the area corresponding to the partial video as a frame within the wide angle of view video before switching, allowing users to recognize the positional relationship and maintaining a seamless transition.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a wide angle of view video is switched to a planar video without displaying the corresponding area, then the switching is simple and quick, but the user cannot recognize the positional relationship leading to a sense of incongruity

Engineering Contradiction:
Improveswitching simplicityVSAvoidpositional relationship information
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The patent applies preliminary action by displaying the area corresponding to the planar video as a frame within the wide angle of view video before the switching occurs. This advance display of the frame shows users where the planar video will appear, allowing them to recognize the positional relationship between the two videos before the transition, thereby eliminating the sense of incongruity while maintaining simple switching operation

Inventive Principle:
Principle #10Preliminary action

2Loss of information

If the area corresponding to the planar video is displayed as a frame before switching, then the positional relationship is clearly recognized, but the device complexity increases

Engineering Contradiction:
Improvepositional relationship informationVSAvoiddisplay control complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the display into two distinct parts: the wide angle of view video and the frame showing the corresponding area. This segmentation allows the system to clearly indicate the positional relationship through the frame while keeping the overall display structure simple and manageable, avoiding excessive device complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The frame acts as an intermediary element between the wide angle of view video and the planar video. It provides visual information about the positional relationship without requiring complex processing or additional hardware, serving as a simple mediator that resolves the information gap during switching

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The present disclosure relates to a reproducing device, a reproducing method, and a program that enable a wide angle of view video and a planar video that is a part of the wide angle of view video to be switched and viewed without a sense of incongruity. A video controller determines whether or not a line quality is capable of bearing a display of the wide angle of view video on the basis of the line quality including a line speed of the wide angle of view video supplied from a server or a remaining amount of buffer data of the wide angle of view video and the partial video. In a case where the line quality is not capable of bearing the display of the wide angle of view video, at a timing immediately before switching the display between the wide angle of view video and the partial video, after the wide angle of view video together with a white frame indicating the angle of view of the partial video corresponding to the wide angle of view video is displayed, and the display is switched to the partial video. It is applicable to a reproducing device.
