Communication and Image Capture File Metadata for Chronological Sorting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to accurately display files chronologically by recording date and time due to the absence of metadata in files obtained from external devices, such as sound files in RIFF Waveform Audio Format (WAV), preventing chronological sorting and filtering by date and time.
Innovation Solution
A communication apparatus and image capture apparatus that store and manage metadata related to creation and update dates and times, and if necessary, obtain recording dates and times for files lacking this information, ensuring accurate chronological display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sound files in RIFF Waveform Audio Format (WAV) are stored without metadata, then the file format compatibility is maintained, but the ability to display files chronologically by recording date and time is lost
Solution Approach 1:
The patent separates the sound file data from its metadata (recording date and time). The mobile device obtains recording date and time information separately from the sound file acquisition process, allowing the WAV file format to remain unchanged while still enabling chronological display capabilities.
Solution Approach 2:
The patent introduces an intermediary mechanism where the mobile device acts as a mediator between the sound file storage and the display system. The device stores recording date and time information in its own storage unit separately from the sound files, then uses this stored information to enable chronological sorting and filtering in the display interface.
2Ease of operation
If metadata is added to files without native metadata support, then chronological sorting capability is improved, but the file format complexity increases
Solution Approach 1:
The patent divides the information storage into two separate components: the original sound file data (unchanged WAV format) and the recording date and time information (stored separately in the mobile device's storage unit). This segmentation allows chronological sorting without modifying the file format itself.
Solution Approach 2:
The patent creates a copy of the recording date and time information in the mobile device's storage unit, separate from the original sound files. This copied metadata enables chronological sorting and filtering operations without requiring modifications to the original WAV file format or its internal structure.
3Productivity
If files are transferred without recording date and time information, then the transfer process is simplified, but the ability to filter and sort files by date and time is lost
Solution Approach 1:
The patent performs preliminary action by having the mobile device obtain and store recording date and time information in advance, during the file acquisition process. This allows the device to maintain simple file transfer operations while still preserving the necessary metadata for later chronological sorting and filtering operations.
Solution Approach 2:
The mobile device serves as an intermediary that captures recording date and time information during file transfer, stores it separately in its storage unit, and then makes this information available for chronological sorting and filtering operations without interfering with the simplicity of the original file transfer process.

AI summary
A communication apparatus that communicates with an external apparatus stores a file obtained from a first external apparatus, and stores first information related to at least one of a creation date and time and an update date and time of the file, and based on a format of the obtained file, determines whether the file is a first file to which the first information can be attached or a second file to which the first information cannot be attached. Where the obtained file is the first file, it is stored into the storage unit and the first information of the first file is stored thereinto, and where the obtained file is the second file, second information related to a recording date and time when the second file has been recorded is obtained and the first information is rewritten into the second information when storing the second file.
