Innovation Solution
An image processing apparatus and method that includes a main device capable of capturing video and audio data, connected to subdevices via wireless communication, allowing for direct device-to-device communication without a router, enabling real-time conversion, display, and transmission of video data to a mobile platform, with features like watermark insertion and encoding for efficient data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If video data is transmitted through traditional encoding and decoding processes, then data can be processed and transmitted, but transmission delay increases and real-time performance deteriorates
Solution Approach 1:
The patent extracts and removes the traditional encoding and decoding processes from the video transmission path. By using device-to-device communication where subdevices transmit raw or minimally processed video data directly to the main device, the system eliminates the time-consuming encoding/decoding cycles that normally occur, thereby reducing transmission delay while maintaining real-time performance.
Solution Approach 2:
The patent introduces a direct wireless communication channel as an intermediary between subdevices and the main device, bypassing traditional routing through encoders/decoders. This direct transmission path allows video data to flow without the intermediate processing steps that cause delays, achieving both low latency and real-time reliability.
2Device complexity
If video data from multiple devices is transmitted through a router, then data routing is simplified, but transmission delay increases and real-time performance deteriorates
Solution Approach 1:
The patent segments the transmission network into direct peer-to-peer connections between subdevices and the main device, eliminating the need for a central router. Each subdevice establishes an independent wireless link directly to the main device, simplifying the routing structure while reducing transmission delay through direct communication paths.
3Adaptability or versatility
If video data is displayed on multiple display regions simultaneously, then user interface flexibility improves, but processing complexity increases
Solution Approach 1:
The patent utilizes the spatial dimension of the display by dividing it into multiple distinct display regions. Each region independently displays video data from different subdevices, allowing the system to handle multiple video streams simultaneously without increasing processing complexity. The spatial separation of display regions enables parallel visualization of multiple video sources.
