Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video production systems face challenges in efficiently incorporating user-generated telestration inputs into output video streams, leading to increased processing and transmission resources, which can hinder performance such as output video stream frame rates.
Innovation Solution
The system employs minimum capture shapes to receive, capture, and transmit user telestration inputs, reducing processing and transmission resources by determining and using these shapes to overlay images with selected video streams, thereby improving performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If user telestration inputs are captured and transmitted using traditional methods, then complete video content is captured, but processing resources and transmission time increase significantly
Solution Approach 1:
The patent extracts only the essential telestration input data (minimum capture shapes) from the complete video content, separating the critical annotation information from the full video stream. This extraction approach captures the necessary telestration data while significantly reducing the volume of data that needs to be processed and transmitted, thereby maintaining capture completeness while improving processing efficiency and frame rate performance
Solution Approach 2:
The patent segments the video content by identifying and isolating specific regions containing telestration inputs (minimum capture shapes). Instead of processing the entire video stream, the system divides the content into relevant telestration regions and transmits only these segmented portions, reducing overall processing load and transmission requirements while preserving complete telestration information
2Loss of information
If traditional image capture methods are used for telestration inputs, then all visual information is captured, but transmission resources and processing time increase
Solution Approach 1:
The system extracts only the minimum necessary visual information (minimum capture shapes) that represents the telestration input, removing redundant visual data from the transmission stream. This extraction maintains the completeness of telestration visual information while significantly reducing the amount of data transmitted, thereby reducing transmission time without losing essential visual content
Solution Approach 2:
The patent changes the parameters of image capture by determining minimum capture shapes and sizes based on the actual telestration content. Instead of capturing fixed-size or full-frame images, the system dynamically adjusts capture parameters to match the actual telestration region, reducing data volume and transmission time while preserving complete telestration visual information
3Reliability
If full video frames are processed for telestration inputs, then complete input data is captured, but processing resources increase significantly
Solution Approach 1:
The system extracts only the relevant telestration input data from full video frames by identifying minimum capture shapes. This extraction process maintains the accuracy and reliability of telestration input capture by focusing on the essential annotation regions while removing redundant frame data, thereby significantly reducing processing resources and energy consumption
Solution Approach 2:
The patent applies local quality processing by determining minimum capture shapes that specifically enclose telestration inputs. Instead of processing entire video frames with uniform quality, the system focuses processing resources on the local regions containing telestration data, maintaining input accuracy where needed while reducing overall processing burden and energy usage

AI summary
Systems, devices and processes and described herein to improve the generation of video content in video production systems. In general, the systems, devices and processes facilitate the incorporation of remotely generated user telestration inputs into output video streams generated by the video production systems. In one embodiment user telestration inputs are received at a control device. Minimum capture shapes corresponding to the user telestration inputs are then determined and images corresponding to the minimum capture shape are captured. The captured images are then transmitted from the control device to the video access point device. At the video access point device the captured images can then be combined with previously captured and transmitted images and overlaid with a selected input video stream. The video input stream with the overlaid image can then be transmitted as an output video stream.
