Image Capture Metadata Transfer for Complete External Recording
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing IP-based broadcasting systems face issues with insufficient metadata transmission when moving image data is recorded and stored in an external apparatus, as metadata generated by the self-video processing apparatus may not be fully transferred to the external destination.
Innovation Solution
An image capturing apparatus is configured to transmit moving image data and generate metadata from start to end of recording, allowing simultaneous transmission of metadata files to an external apparatus via communication means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the self-video processing apparatus directly transmits the additional information file stored in itself to the external apparatus, then the transmission process is simple, but the metadata to be referred to by the external apparatus is insufficient
Solution Approach 1:
The patent applies preliminary action by generating and transmitting metadata at the start of recording before the actual recording ends. The metadata generation unit creates metadata files containing information about the moving image data being recorded, and this metadata is transmitted to the external apparatus in advance, ensuring the external apparatus has complete information without requiring complex post-recording processing.
2Speed
If metadata is generated and transmitted only at the start of recording, then the transmission is timely, but metadata about the end of recording is missing
Solution Approach 1:
The patent implements continuity of useful action by establishing a continuous metadata transmission process that operates throughout the entire recording duration. The metadata generation unit continuously generates metadata from the start of recording through to the end, and the transmission unit continuously transmits this metadata to the external apparatus, ensuring no information gaps occur during the recording process.
3Device complexity
If the additional information file is stored only in the self-apparatus, then storage management is simple, but the external apparatus cannot access complete metadata
Solution Approach 1:
The patent uses the communication unit as an intermediary to transfer metadata from the self-apparatus to the external apparatus. The transmission unit receives additional information files containing metadata and transmits them via the communication unit to the external apparatus, enabling the external apparatus to access complete metadata without requiring direct storage access or complex inter-apparatus storage management protocols.

AI summary
An image capturing apparatus including communication means and configured to transmit, via the communication means, moving image data obtained by image capturing to an external apparatus configured to record the moving image data, comprising: moving image transmission means for, upon receiving an instruction to start recording, transmitting the moving image data obtained by image capturing by image capturing means to the external apparatus via the communication means, and upon receiving an instruction to end the recording, ending the transmission of the moving image data to the external apparatus; metadata generation means for, upon receiving the instruction to start the recording, generating metadata associated with the start of the recording of the moving image data, and upon receiving the instruction to end the recording, generating metadata associated with the end of the recording of the moving image data; and metadata transmission means for, upon receiving the instruction to end the recording, transmitting metadata from the start of the recording to the end of the recording to the external apparatus via the communication means.
