UHD Video Replay Clip Insertion for Broadcast Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In live sporting events, high-definition (HD) video replay can be challenging due to limited screen space and quality degradation when zooming in on scenes of interest, as the resolution of the zoomed portion is often lower than the original, making it difficult to accurately determine events like possession or contact.
Innovation Solution
Capturing a second video stream in ultra-high definition (UHD) resolution from the same vantage point, which is then edited to create video clips that can be seamlessly inserted into the HD broadcast feed, maintaining or exceeding HD resolution when zoomed, thus enhancing the viewing experience without degrading image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If zooming in on the scene of interest is performed to focus on critical details, then the area of focus is improved, but the picture quality deteriorates due to resolution loss
Solution Approach 1:
The video stream is divided into multiple clips, each focusing on a specific scene of interest. By segmenting the original video into multiple targeted clips with different zoom levels and perspectives, the system can provide detailed views of critical areas without degrading overall picture quality, as each clip is independently processed and optimized for its specific focus area
Solution Approach 2:
Different portions of the video stream are processed with different quality levels and zoom factors according to their importance. Scenes of interest receive enhanced processing with higher zoom and localized quality improvement, while non-critical areas maintain standard quality, thereby allocating resources efficiently and avoiding universal quality degradation
2Manufacturing precision
If the resolution of the video stream is increased to maintain quality when zoomed, then the picture quality is improved, but the device complexity increases due to multiple video streams
Solution Approach 1:
Multiple video clips are pre-generated from the original video stream at different zoom levels and perspectives before broadcast. This preliminary processing allows the system to have ready-to-use high-resolution clips for scenes of interest, eliminating the need for real-time complex processing during broadcast and reducing overall system complexity
Solution Approach 2:
Multiple copies of the video stream are created with different processing characteristics (zoom levels, perspectives, resolutions). These copies are generated in advance and stored, allowing the broadcast system to simply select and play the appropriate clip rather than performing complex real-time processing, thereby reducing device complexity
3Adaptability or versatility
If multiple video clips are created from the second video stream to cover different scenes of interest, then the versatility is improved, but the loss of time increases due to clip processing
Solution Approach 1:
Multiple video clips covering different scenes of interest are generated in advance from the original video stream. This preliminary action creates a library of pre-processed clips that can be quickly selected and broadcast without requiring time-consuming real-time processing, thus maintaining versatility while minimizing time loss during actual broadcast
Solution Approach 2:
The system dynamically selects and switches between multiple pre-generated video clips based on the broadcast needs and viewer interest. This dynamic selection capability allows the system to adapt to different viewing requirements without reprocessing video material, maintaining versatility while avoiding repeated processing time losses
Data Source
AI summary
Techniques to provide an enhanced video replay are described. A processor component controls a video interface module, a replay clip editing module, a replay clip selection module, and a broadcast feed module. The video interface module may receive a first and a second video stream of an event in a first and a second video resolution. The replay clip editing module may determine a time period within the second video stream that contains a scene of interest and create multiple video clips in the first video resolution. The multiple video clips each represent of a portion of the field of view of the second video stream. The broadcast feed module may interrupt a broadcast feed of the first video stream and insert the selected one of the multiple video clips into the broadcast feed. Other embodiments are described and claimed.
