Supporter Computer Mediator for Live Video Character Animation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video distribution systems that generate animation of a character object based on an actor's motions during live distribution face challenges when unexpected situations occur, such as equipment failures, leading to adverse effects on video quality due to the need for actors or camera operators to handle these situations, which can result in inappropriate camerawork or motion reflections in the character object's animation.
Innovation Solution
A video distribution system that includes a distribution server and a supporter computer, which allows for real-time adjustments and additional information display on a display device visible to the actor, enabling easier handling of unexpected situations by modifying the character object, displaying additional information, and controlling the video distribution to client devices, including the option to prohibit distribution to specific users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the actor or camera operator handles unexpected situations during live distribution, then the system can respond to equipment failures, but the character object's animation quality deteriorates due to reflected motions or inappropriate camerawork
Solution Approach 1:
The patent introduces a supporter computer as an intermediary device that receives operation inputs from the operator and transmits control signals to modify the character object's animation. This mediator allows the operator to handle unexpected situations without directly affecting the character's motion, thereby maintaining animation quality while responding to equipment failures.
Solution Approach 2:
The system separates the control functions into distinct segments: the supporter computer handles operator inputs and control signal generation, while the character object animation is independently controlled through modification generation. This segmentation allows independent optimization of both the operator's ability to handle failures and the animation quality.
2Loss of information
If additional information is displayed on the client device during live distribution, then viewers receive more information, but the video quality and immersion are reduced
Solution Approach 1:
The patent applies local quality by displaying additional information selectively - only on the supporter computer (local to the operator) rather than on all client devices. This allows information delivery to the operator for handling unexpected situations without degrading the video quality experienced by viewers on client devices.
3Loss of information
If the system displays information only on client devices, then viewers receive information, but the operator cannot receive real-time feedback to handle unexpected situations
Solution Approach 1:
The supporter computer serves as an intermediary that receives operation inputs from the operator and generates control signals to modify the character object's animation. This mediator enables real-time feedback to the operator without requiring information display on client devices, thereby improving ease of operation while maintaining video quality.

AI summary
A video distribution system in one embodiment includes a distribution server, a storage and a supporter computer. The distribution server may be configured to cause a first display device and a plurality of client devices to play a live video containing an animation of a character object. A supporter computer may be configured to display in the live video, upon selection of a decorative object and receipt of a first operation input, a blind object for hiding at least a part of the character object.
