Content Receiver 3D Video Metadata Export
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video content receivers lack the ability to effectively utilize 3D video content on removable media, as they do not provide a method to determine if the exported content includes 3D video and manage this information appropriately.
Innovation Solution
A content receiver with a download control unit and an output control unit that records 3D video information in the management metadata of an external medium, allowing for the determination of 3D video presence in exported content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If video content is exported to an external medium, then the content can be stored and transferred, but information about 3D video presence is lost and cannot be determined from the exported content
Solution Approach 1:
The patent applies preliminary action by recording 3D video information in the management information of the external medium at the time of content export. This ensures that when content is transferred to external storage, the metadata about 3D video presence is simultaneously preserved in the file system's management structures, making it immediately available for future determination without additional processing.
Solution Approach 2:
The patent uses management information (metadata) as an intermediary between the video content and the determination of 3D video presence. Instead of embedding 3D information directly in the video data or requiring complex analysis of the content itself, the system maintains a separate management information structure that stores 3D video flags, which act as a mediator for quick and easy determination of 3D content properties.
2Reliability
If 3D video information is recorded in management information during content export, then determination of 3D video presence becomes possible, but the complexity of the export process increases
Solution Approach 1:
The patent applies universality by designing the output control unit to handle both regular content export and 3D video information recording through a single integrated process. The management information structure is designed to accommodate multiple types of metadata (content descriptors, rights information, and 3D video flags) in a unified format, allowing the same export mechanism to serve multiple functions without requiring separate specialized systems.
3Adaptability or versatility
If management information is updated with 3D video flags, then usability of exported content is enhanced, but the processing time during export increases
Solution Approach 1:
The system performs preliminary action by preparing and storing 3D video information in the management information structure during the initial export process. This upfront recording eliminates the need for time-consuming analysis or processing when the content is later accessed or transferred, as the 3D video presence is already determined and stored in the metadata, enabling instant adaptability when the content is used on different devices.

AI summary
In a receiver for downloading video content including 3D video and outputting the downloaded video content to a removable medium, information concerning 3D video is made usable also by the removable medium.A content receiver includes a download control unit for receiving, via a network, video content and reproduction control information for use in reproducing and outputting, to outside, the video content and an output control unit for exporting the received video content to an external medium. In the content receiver, when outputting the video content to an external medium, the output control unit records, based on first 3D video information delivered being included in the reproduction control information and indicating a state of 3D video existence in the video content, second 3D video information indicating whether the video content includes 3D video in management information of the external medium for recording the video content.
