Multimedia Watermark Metadata Acquisition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multimedia content management techniques face challenges in reliably maintaining metadata integrity, particularly during format transformations and transmissions, leading to loss of interactive features and metadata.
Innovation Solution
The use of embedded watermarks with server codes and interval codes in multimedia content, enabling automatic content recognition and metadata acquisition through a system that detects and decodes these watermarks to retrieve associated metadata from designated servers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If metadata is interleaved, prepended or appended to multimedia content, then metadata can enable content management and interactive services, but metadata occupies additional bandwidth and can be lost during format transformation, transcoding, and transmission
Solution Approach 1:
The patent embeds metadata watermarks directly within the multimedia content structure, nesting the metadata information inside the content itself rather than placing it externally. This allows metadata to be carried along with the content through various processing operations without being separated or lost, resolving the contradiction between enabling interactive services and preventing metadata loss during transmission and format conversion
Solution Approach 2:
The patent creates watermark copies of metadata that are embedded into the multimedia content. These watermark copies serve as redundant metadata representations that can be extracted even when the original metadata is lost during transcoding or format transformation, thereby maintaining metadata integrity while enabling content management and interactive services
2Ease of operation
If metadata is transmitted through communication protocols and interfaces, then content management is enabled, but metadata can be lost during transmission and processing
Solution Approach 1:
The patent embeds watermark copies of metadata within the multimedia content, creating redundant metadata representations that travel with the content through various communication protocols and interfaces. This ensures metadata delivery reliability while maintaining ease of content management operations
Solution Approach 2:
The patent performs preliminary embedding of metadata watermarks into the multimedia content before transmission and processing operations. This preliminary action ensures that metadata is already integrated and protected against loss during subsequent transmission through communication protocols and interfaces, resolving the contradiction between ease of operation and reliability

AI summary
Methods, devices and computer program products are described that improve acquisition of metadata that is associates with a multimedia content, such an audio or video content. In one exemplary method, the multimedia content is received at a first device that is equipped with a watermark detector and watermark extraction operations are conducted to detect a plurality of watermark messages. Each watermark message includes a server code and an interval code. In this method, a server Internet Protocol (IP) address is obtained that corresponds to a server that stores at least a portion of the metadata associated with the multimedia content. The IP address corresponds to at least one of the server codes detected from the plurality of watermark messages. According to the above method, the metadata is requested from the server having the server IP address, and a response including the metadata associated with the multimedia content is received.
