Multimedia Content Sharing via Metadata Extraction and MPU Splitting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing broadcast technologies lack real-time sharing capabilities of multimedia content while users are watching or listening, and they require significant server resources for partial content sharing, leading to difficulties in sharing content in real time due to increased processing and network interaction times.
Innovation Solution
A method and apparatus that utilize a second client to receive multimedia content from a server, where the client generates request information based on sharing information from a first client, allowing for real-time sharing of selected multimedia content without generating new URLs or increasing server storage, using the Moving Picture Experts Group (MPEG) media transport (MMT) protocol to split multimedia content into media processing units (MPUs) and transmit feature information alongside the content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the server generates new URLs and creates new multimedia content for sharing, then content sharing capability is improved, but server processing time and storage requirements increase
Solution Approach 1:
The patent extracts the essential identifying information (URL and time stamp) from the original multimedia content request, separating this metadata from the actual content retrieval process. This allows the server to share content references without duplicating or regenerating the actual multimedia files, significantly reducing processing time and storage requirements while maintaining full sharing functionality
2Adaptability or versatility
If the server generates new URLs for each shared content instance, then real-time sharing is enabled, but the amount of content stored in the server increases
Solution Approach 1:
Instead of creating duplicate content instances, the patent uses lightweight metadata copies (URL and time stamp information) that reference the original content. This allows multiple users to access and share the same content through different metadata instances without increasing the actual content storage, enabling real-time sharing while maintaining efficient server resource utilization
3Reliability
If the server processes and searches for content for each sharing request, then accurate content delivery is ensured, but network interaction time increases
Solution Approach 1:
The patent performs preliminary content identification by capturing the URL and time stamp metadata at the moment of content request, before any sharing operations occur. This pre-extracted metadata serves as a ready-to-use reference that eliminates the need for repeated server searches and content verification during sharing operations, ensuring accurate content delivery while minimizing network interaction time

AI summary
Provided are a method and an apparatus for transmitting and sharing multimedia content. A method in which a second client receives, from a server, multimedia content provided by the server to a first client, includes: receiving, from the first client, sharing information regarding at least one piece of the multimedia content, the at least one piece being selected to be shared from among pieces of the multimedia content received by the first client; generating request information of the multimedia content based on the sharing information; transmitting the request information to a server in which the multimedia content is stored; and receiving the multimedia content retrieved by the server based on the request information, wherein the multimedia content is provided together with feature information representing details of the multimedia content.
