Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If online matching processing is used to acquire additional information from a video recognition device through a communication network, then the accuracy of content recognition is improved, but the processing time and network dependency increase
Solution Approach 1:
The patent divides the video signal into multiple frames and extracts specific regions (such as logos) from each frame for separate recognition processing. This segmentation allows the system to process only relevant portions of the video data, reducing overall processing time while maintaining recognition accuracy through focused analysis of key elements.
Solution Approach 2:
The system performs preliminary extraction of content recognition information from video frames before transmitting data to the video recognition device. By pre-processing and preparing the data in advance, the system reduces the time required for online matching and enables faster acquisition of additional information when needed.
2Measurement precision
If online matching processing is performed through a communication network, then content recognition accuracy is improved, but system complexity and network dependency increase
Solution Approach 1:
The patent extracts and transmits only essential content recognition information (such as extracted features or descriptors) to the video recognition device, rather than transmitting entire video frames or redundant data. This extraction approach simplifies the online matching process by reducing data transmission requirements and focusing only on critical recognition elements.
Solution Approach 2:
The system introduces an additional information distribution device that acts as an intermediary, storing pre-acquired additional information and transmitting it directly to the video reception device. This intermediary reduces the need for direct real-time communication between the video reception device and video recognition device, simplifying the overall system architecture and reducing network dependency.
3Measurement precision
If additional information is acquired through online matching with a video recognition device, then information accuracy is improved, but real-time processing capability deteriorates
Solution Approach 1:
The additional information distribution device pre-acquires and stores additional information from the video recognition device before it is needed. This preliminary preparation allows the video reception device to quickly retrieve accurate additional information without waiting for real-time online matching, thereby maintaining both information accuracy and real-time processing speed.
Solution Approach 2:
The system creates and distributes copies of additional information through the additional information distribution device. Instead of requiring the video reception device to perform online matching for each request, pre-acquired copies of additional information are made available for rapid retrieval, enabling real-time processing while maintaining accuracy through verified data sources.
4Reliability
If the system performs both online and local matching processing, then reliability of content recognition is improved, but device complexity increases
Solution Approach 1:
The patent implements a segmented processing approach where local matching is performed first on extracted content recognition information, and only when local matching fails or additional confirmation is needed does the system proceed to online matching. This segmentation of processing stages improves reliability through multiple verification levels while managing complexity by activating full online processing only when necessary.
Solution Approach 2:
The additional information distribution device serves as an intermediary that simplifies the dual-matching process by providing pre-verified additional information. This intermediary layer reduces the complexity burden of performing both local and online matching by offering a trusted source of additional information that can be used to validate or supplement recognition results from either matching approach.

AI summary
Video recognition processing regarding a video signal input from an outside is performed. Hence, video reception device configured to transmit/receive data through communication network includes video recognition unit. The video recognition unit is configured to perform at least one of: online matching processing for generating second content recognition information from a partial video extracted by video extraction unit, transmitting the second content recognition information to video recognition device so as to request video recognition device to perform video recognition processing; and local matching processing for collating the second content recognition information with first content recognition information included in a local database stored in storage unit.
