Transition Identification Metadata for Omnidirectional Video Viewpoint Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Client devices lack information on transitionable omnidirectional videos, impairing the viewing experience by not allowing appropriate video transitions as intended by content creators.
Innovation Solution
A metadata generation unit creates transition identification information to identify viewable viewpoints, which is stored in files alongside video data, enabling clients to recognize and switch between viewable viewpoints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If transition identification information is not provided to client devices, then the file structure remains simple, but the viewing experience quality deteriorates due to inability to perform intended video transitions
Solution Approach 1:
The patent applies preliminary action by pre-generating and embedding transition identification information in the video file during the file creation process. The metadata generation unit creates this information beforehand, and the file generation unit incorporates it into the video file structure, so that client devices can immediately use it for viewpoint transitions without needing external information sources.
2Adaptability or versatility
If transition identification information is embedded in video files, then viewpoint transitions can be properly implemented, but the file structure and processing complexity increase
Solution Approach 1:
The patent applies segmentation by dividing the video content into multiple viewpoint videos (first viewpoint video, second viewpoint video, etc.) and associating each with specific transition identification information. This allows the system to manage complex transitions through modular, organized segments rather than requiring a monolithic complex structure.
Solution Approach 2:
The patent uses transition identification information as an intermediary element that mediates between the video content and the client device's reproduction functions. This intermediary metadata layer enables viewpoint transitions without requiring direct complex interactions between the video data and the client's video playback mechanisms.
3Reliability
If creator's intention for video transitions is not encoded, then the content delivery system remains simple, but the viewing experience fails to reflect intended transitions
Solution Approach 1:
The patent applies preliminary action by having the metadata generation unit pre-process the video content during file generation to embed transition identification information that reflects the creator's intended transitions. This preliminary encoding ensures that when the video is delivered and reproduced, the client device can automatically follow the creator's intended transition path without requiring complex real-time analysis or manual configuration.
Data Source
AI summary
Provided are an information processing device, an information processing method, a reproduction processing device, and a reproduction processing method that provide a high-quality viewing experience to a user. A metadata generation unit generates transition identification information for identifying a second viewpoint that is a viewpoint position of a second video transitionable from a first video whose viewpoint position is a first viewpoint. A file generation unit generates a file including data of the first video data and the transition identification information.
