OSD Information Generation Camera and Synthesis Terminal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional CCTV systems have a one-way information delivery structure, limiting user authorization and requiring separate communication systems for information sharing, which compromises security and privacy.
Innovation Solution
An OSD information generation camera and terminal system that separately transmits and synthesizes images and OSD information based on user authorization and screen splitting criteria, allowing secure and private information exchange without additional communication systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the image and OSD information are immediately synthesized in conventional CCTV systems, then the information can be displayed to users, but any user viewing the image can read the information regardless of authorization, compromising security
Solution Approach 1:
The patent segments the information delivery process by separating OSD information transmission from image transmission. The OSD information is transmitted independently through a communication unit, while the image is transmitted through a separate path. This segmentation allows the terminal to control whether to synthesize and display OSD information based on user authorization, thereby resolving the security issue while maintaining a relatively simple overall system structure.
2Adaptability or versatility
If a separate communication system is used for information exchange between users, then information sharing is enabled, but the system complexity increases and privacy protection is compromised
Solution Approach 1:
The terminal device performs multiple functions: it receives both image data and OSD information, determines user authorization, controls synthesis of the two, and manages display. This multi-functional design eliminates the need for separate communication systems for information exchange, as the same terminal handles both image viewing and information sharing, thereby reducing overall system complexity while maintaining versatile information sharing capabilities.
3Reliability
If the image and OSD information are transmitted separately, then user authorization can control information access, but the system requires separate transmission paths
Solution Approach 1:
The patent implements segmentation by using a separate communication unit for transmitting OSD information compared to the image transmission path. This allows the system to control information access through authorization checks at the terminal while maintaining relatively simple transmission structures. The segmentation enables independent control of information flow without requiring complex integrated transmission protocols.
4Ease of operation
If OSD information is shared without authorization checks, then information exchange is simplified, but security and privacy are compromised
Solution Approach 1:
The terminal device autonomously performs authorization checks before synthesizing and displaying OSD information. The system self-manages the security control process by determining whether the current user has authorization to access OSD information, eliminating the need for manual authorization management or complex external authentication systems. This self-service approach maintains ease of operation while ensuring privacy protection through automated authorization verification.

AI summary
An on screen display (OSD) information generation camera and an OSD synthesis terminal are provided. The OSD information generation camera is configured to captured an image, generate OSD information related to the image, and transmit the image and the OSD information to the OSD synthesis terminal which is configured to synthesize the image and the OSD information according to a predetermined condition. The OSD synthesis terminal is further configured to generate another OSD information in response to a user instruction, and transmit the other OSD information to another OSD synthesis terminal.
