Media Cloud Server Segmenting Broadcast Content for User Synthesis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in creating desired video content due to the challenge of finding suitable locations and equipment, and the high cost of chroma keying synthesis equipment, making it inconvenient for general users to produce and edit content.
Innovation Solution
A media cloud server that segments and stores real-time broadcast content, allowing users to create content by extracting and synthesizing segments based on user scenarios through metadata matching, enabling easy content creation and sharing across devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If users use camera equipment to shoot and edit images personally, then they can create desired video content, but it requires high level of skill and is inconvenient to find suitable locations and cast
Solution Approach 1:
The patent uses chroma keying technology to replace the need for physical location shooting by copying and compositing backgrounds from stock footage or digital images. Users can create professional-looking videos without visiting actual locations by keying out green screens and inserting pre-recorded background scenes.
Solution Approach 2:
The patent introduces chroma keying equipment as an intermediary tool that facilitates the combination of foreground subjects and background scenes. This mediator technology enables users to composite multiple video elements without requiring physical presence at shooting locations or coordination of casts for background scenes.
2Adaptability or versatility
If users use chroma keying synthesis equipment to create video content, then they can synthesize various types of images, but the equipment is highly expensive and not available to general users
Solution Approach 1:
The patent describes a chroma keying system that can handle multiple types of video synthesis operations including green screen keying, blue screen keying, and various background replacement techniques. This multi-functional equipment allows users to create diverse video content with a single device, maximizing versatility while controlling cost.
Solution Approach 2:
The patent divides the video synthesis process into separate functional modules including color keying, background insertion, and video mixing. This segmentation allows the system to perform complex synthesis operations through coordinated simple functions, reducing overall system complexity and cost while maintaining high adaptability.
3Ease of manufacture
If users personally edit images shot using camera equipment, then they can create customized content, but it requires high level of skill
Solution Approach 1:
The patent describes automated chroma keying systems that can automatically detect and key out background colors without requiring manual adjustment of keying parameters. The system self-adjusts threshold values and smoothing parameters to achieve optimal results, eliminating the need for users to have advanced editing skills while maintaining high customization capability.
Data Source
AI summary
A method and a media cloud server for creating content are disclosed. The method includes: recording and storing a real-time broadcast content transmitted through a broadcaster system; dividing the stored broadcast content according to a predetermined method and storing the segments; storing metadata including descriptions of the segments; and creating a user content by extracting at least one segments using the metadata and synthesizing the extracted segments in response to a request from a client device.
