Content Transmission System with Metadata-Embedded Processing Instructions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current content transmission systems, such as those using UPnP, require separate and labor-intensive operations for content uploading and recording, making it cumbersome for users to upload and store content on networked devices.
Innovation Solution
A content transmission system that includes a content sending apparatus with a metadata attaching unit, an execution processing insertion unit, and a data sending unit to attach and send metadata with processing instructions, allowing the content reception apparatus to automatically execute processing tasks like copying, moving, or deleting content after reception, using XML statements for communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate operations are used for content uploading and recording processing, then processing reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The patent combines content uploading and recording processing into a single integrated operation. The content sending apparatus sends both the content data and the recording instruction metadata together in one transmission, eliminating the need for separate upload and record operations. This merging of operations improves ease of operation while maintaining processing reliability through the structured metadata format.
2Manufacturing precision
If multiple separate processing steps are required for content upload and recording, then processing precision is improved, but loss of time increases
Solution Approach 1:
The patent implements preliminary action by embedding the recording instruction metadata along with the content data during the upload process itself. The reception apparatus is pre-instructed with the recording parameters and can execute the recording operation immediately upon receiving the content, without requiring additional user input or separate processing steps. This eliminates time loss while maintaining processing precision through the structured metadata format.
3Productivity
If automatic processing execution is implemented, then productivity is improved, but device complexity increases
Solution Approach 1:
The patent uses metadata as an intermediary carrier that conveys recording instructions from the sending apparatus to the reception apparatus. This metadata structure acts as a standardized interface that enables automatic processing execution without requiring complex device logic. The reception apparatus simply needs to parse and execute the instructions contained in the metadata, which maintains device simplicity while achieving high productivity through automation.
