Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a physical console with analog controls is used for video editing, then video control functions can be performed, but the device complexity and ease of operation deteriorate due to cumbersome physical buttons and scroll wheels
Solution Approach 1:
The patent replaces the mechanical physical console system with a cloud-based software system accessed through a standard touch screen device. The mechanical buttons, scroll wheels, and physical controls are substituted with virtual controls and gesture-based interaction, eliminating the need for specialty physical equipment while maintaining full video control functionality.
Solution Approach 2:
The patent makes the control system universal by allowing any standard touch screen device (smartphone, tablet, laptop) to function as the video control interface. This eliminates the need for dedicated physical consoles and allows multiple users to access the same system through different devices, significantly improving ease of operation.
2Productivity
If multiple video streams are controlled simultaneously, then productivity improves, but the difficulty of detecting and measuring increases due to the need for precise synchronization across multiple streams
Solution Approach 1:
The patent implements feedback mechanisms that display the current state of each video stream, including timestamp information and synchronization status. This feedback allows the system to detect and measure the state of multiple streams simultaneously, enabling precise synchronization control while maintaining high productivity.
Solution Approach 2:
The patent segments the control interface into separate, manageable controls for each video stream, with each stream displaying its own timestamp and control options. This segmentation makes it easier to detect and measure the state of each individual stream while maintaining the ability to control multiple streams simultaneously.
3Ease of operation
If cloud-based control is implemented, then ease of operation improves through intuitive gestures, but loss of time may increase due to network latency
Solution Approach 1:
The patent implements preliminary actions by pre-synchronizing video streams in the cloud before playback begins. Timestamp synchronization and stream alignment are performed in advance, so that when playback starts, the streams are already aligned and ready for immediate precise control, minimizing any perceived latency during actual usage.
Data Source
AI summary
Systems and methods for controlling video functions across multiple video streams are provided. Multiple video streams are recorded at an event via a corresponding multiple of video sources, the multiple video streams being synchronized in time with each other. The multiple video streams are displayed on a display device. One or more of the multiple video streams may be selected via a touch screen of the display device, which are then presented for playback on the display device. Control of video functions of the selected video streams is enabled via finger gestures on the touch screen of the display device. The video functions may comprise video selection, play, pause, fast forward, rewind, zoom, focus, shuttle, scrub, seek, frame advance, and the like. In the event two or more of the multiple video streams are selected, the two or more video streams may be controlled simultaneously and synchronously.
