Live Video Crop Editing System for Multi-Angle Streaming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing live video editing systems require expensive and specialized equipment to manage multiple camera angles, which is not efficient or cost-effective for seamless live video streaming and recording.
Innovation Solution
A video stream encoding system that uses a single camera to capture an ultra-high definition video stream, producing two streams - a full field of view for operators and a cropped view for viewers, allowing for live multiple-camera production environments without the need for multiple cameras.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple cameras are used to capture different camera angles for live video editing, then the ability to provide multiple perspectives is improved, but the equipment cost and system complexity increase significantly
Solution Approach 1:
The patent segments the full ultra-high definition video stream into multiple cropped video streams, each representing a different camera angle or perspective. The video processing system divides the single high-resolution input into multiple lower-resolution output streams through digital cropping and encoding, eliminating the need for multiple physical cameras while achieving the same multi-angle effect
Solution Approach 2:
The patent creates digital copies of the video feed at different crop regions, generating multiple perspective views from a single camera capture. Each cropped stream is a digital reproduction of a specific region of interest from the full-frame ultra-high definition video, allowing multiple camera angle simulations without additional hardware
2Adaptability or versatility
If multiple cameras are used to capture different camera angles for live video editing, then the ability to provide multiple perspectives is improved, but the equipment cost increases
Solution Approach 1:
The patent makes a single ultra-high definition camera perform the function of multiple cameras by capturing footage at a resolution high enough to contain multiple independent viewports. The single camera system becomes universal, capable of providing multiple camera angle perspectives through software-based cropping and encoding rather than requiring separate dedicated cameras for each angle
Solution Approach 2:
The patent changes the resolution parameter of the video streams by capturing at ultra-high definition and then encoding cropped regions at lower resolutions. This parameter transformation allows the system to derive multiple lower-resolution streams from a single high-resolution source, reducing hardware requirements while maintaining multiple perspective capabilities
3Loss of information
If full field of view video is transmitted to all devices, then complete visual information is provided, but data transmission requirements and network bandwidth increase
Solution Approach 1:
The patent applies local quality by transmitting full-resolution ultra-high definition video only where needed (e.g., to editing devices or displays requiring complete view), while transmitting cropped lower-resolution streams to devices that only need specific regions of interest. This localized quality adjustment optimizes bandwidth usage by matching transmission resolution to actual device requirements
Solution Approach 2:
The patent transmits only the necessary portion of the video data to each device based on its requirements. Devices receiving cropped streams get partial video information (specific regions only) rather than the complete full-field view, reducing overall network bandwidth consumption while ensuring each device receives sufficient data for its intended function
Data Source
AI summary
Implementations of the disclosure provide for video stream encoding system with live crop editing and recording. In one implementation, the method comprises receiving, by a camera device, an input video stream depicting an image. A first video stream and a second video stream are generated based on the input video stream. A crop instruction associated with the image is received based on user input. A region of interest in the first stream is determined based on the crop instruction. The first stream depicts a full field of view of the image associated with the input video stream. A cropped view presentation of the full field of view is generated to associate with the second stream in accordance with the region of interest. Thereupon, a portion of the cropped view presentation of the second stream is provided for display at a network device.
