Multi-View Content Recording With Stream Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-streaming technologies fail to effectively record and reproduce content that is outputtable in multi-view, as they do not consider the potential for simultaneous recording and playback of multiple content streams.
Innovation Solution
An electronic apparatus and method that includes identifying multi-view content through a multi-view identifier, obtaining and storing multi-view information, and synchronizing multiple content streams for recording and playback in multi-view mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If content is recorded using traditional single-stream recording methods, then the recording process is simple and storage requirements are low, but the recorded content cannot be reproduced in multi-view mode
Solution Approach 1:
The system performs preliminary actions by detecting multi-view identifiers during content transmission and proactively obtaining related content streams before recording completes. The recording apparatus identifies multi-view content through identifiers in transport stream headers, metadata, or video frames, then automatically retrieves additional content streams in advance to ensure complete multi-view reproduction capability.
Solution Approach 2:
The recording apparatus is designed with multi-functionality to handle both single-view and multi-view recording modes. It can detect multi-view identifiers, obtain related content streams, store multiple content streams together with their synchronization information, and reproduce content in either single-view or multi-view modes depending on user requirements.
2Adaptability or versatility
If multi-view content is recorded by obtaining and storing multiple content streams, then multi-view playback is enabled, but storage space requirements and processing complexity increase
Solution Approach 1:
The system obtains related content streams in advance during the recording process by detecting multi-view identifiers and querying content information from content information servers. This preliminary acquisition ensures that all necessary content for multi-view reproduction is available before playback, avoiding the need for additional storage during playback operations.
Solution Approach 2:
The system uses content information servers as intermediaries to manage content stream acquisition. These servers provide metadata and content location information that enables efficient retrieval of related content streams, reducing the direct storage burden on the recording apparatus while maintaining complete multi-view content availability.
3Adaptability or versatility
If the system obtains multi-view information by accessing content information servers, then complete multi-view content can be retrieved, but network dependency and acquisition time increase
Solution Approach 1:
The system performs content information acquisition in advance during the content transmission period. By detecting multi-view identifiers and querying content information servers while the content is being transmitted, the system obtains all necessary content metadata and stream information before recording completes, eliminating post-recording acquisition delays.
Solution Approach 2:
The content information acquisition process runs continuously during content transmission without interrupting the recording operation. The system simultaneously receives content streams, detects multi-view identifiers, and queries content information servers in parallel, maintaining continuous useful action throughout the content delivery period to minimize total acquisition time.

AI summary
An operating method of an electronic apparatus includes receiving a request to record first content; based on the first content being outputtable in multi-view, obtaining multi-view information for outputting the first content in multi-view; and storing the multi-view information together with the first content.
