Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different types of CCTV cameras with different streaming schemes and codecs are integrated into the video management system, then the system's adaptability and versatility improve, but the device complexity and compatibility issues worsen
Solution Approach 1:
The patent introduces a video distribution apparatus as an intermediary component between CCTV cameras and client applications. This apparatus receives video signals from various CCTV cameras using different codecs and streaming schemes, then converts and redistributes them in a standardized format. The intermediary handles the complexity of multiple protocols internally while presenting a unified interface to clients, thus improving adaptability without increasing visible system complexity.
Solution Approach 2:
The video distribution apparatus is designed with multi-functional capabilities to handle various video formats, codecs, and streaming schemes simultaneously. It can process different input formats from multiple CCTV camera types and output a universal standardized format that any client application can use. This universality allows the system to accommodate diverse camera types without requiring separate dedicated applications for each camera type.
2Ease of operation
If client applications individually request streaming from each CCTV camera, then the system's ease of operation improves, but the loss of energy and bandwidth wastage worsen
Solution Approach 1:
The patent merges multiple individual streaming requests into a single centralized distribution process. Instead of each client application separately requesting streams from individual CCTV cameras, the video distribution apparatus consolidates the streaming function. It receives video signals from cameras once and then distributes them to multiple clients simultaneously, eliminating redundant transmissions and reducing overall bandwidth consumption while maintaining ease of operation for clients.
3Adaptability or versatility
If video is converted to desired size at the client application end, then the adaptability to different client needs improves, but the loss of energy and processing load worsen
Solution Approach 1:
The patent implements preliminary action by performing video format conversion and resizing operations in advance at the video distribution apparatus before transmission to client applications. The apparatus pre-processes video signals to convert them into various desired sizes and formats based on client requirements. This eliminates the need for client applications to perform resource-intensive conversion operations locally, thereby reducing client processing load and energy consumption while maintaining adaptability to different client needs.

AI summary
The present disclosure provides a multi-channel video distribution method and apparatus, and a video management system using the same, including a client system to communicate with a standardized video providing apparatus or a non-standardized video providing apparatus, and to receive a video/sound signal from the standardized video providing apparatus or the non-standardized video providing apparatus; a transcode system to convert the video/sound signal, received by the client system, to a video/sound format that is requested in a client application; and a server system to communicate with the client application, and to transmit, to the client application, the video/sound signal that is converted by the transcode system.
