Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In surveillance systems where network cameras communicate with client devices via a gateway, there is a trade-off between image transmission time and battery life, with high compression rates shortening image transmission time but reducing image quality, and low compression rates extending battery life but increasing transmission time.
Innovation Solution
A network camera system that generates and transmits data packets with optional headers, allowing for efficient packet retransmission and dynamic adjustment of image transmission conditions, such as resolution and compression, to reduce image transmission time without increasing compression rates, thereby extending battery life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the compression rate of the image is increased, then the image transmission time shortens, but the image quality deteriorates
Solution Approach 1:
The patent segments the image data into multiple data packets for transmission. By dividing the image into packets and transmitting them in batches, the system optimizes transmission efficiency without requiring excessive compression, thereby reducing transmission time while preserving image quality.
Solution Approach 2:
The patent implements preliminary actions by storing data packets in a buffer before transmission and preparing retransmission packets in advance. This allows the system to manage transmission more efficiently, reducing actual transmission time without compromising image quality through over-compression.
2Manufacturing precision
If the compression rate of the image is decreased, then the image quality is enhanced, but the image transmission time increases and battery life shortens
Solution Approach 1:
By segmenting image data into multiple packets, the system can transmit data in optimized batches rather than as a single large block. This segmentation allows for more efficient transmission management, reducing overall transmission time while maintaining lower compression rates that preserve image quality.
Solution Approach 2:
The patent ensures continuous useful action by implementing a buffer system that continuously prepares and manages data packets for transmission. This continuous management optimizes the transmission process, reducing total transmission time without requiring higher compression rates, thus preserving both image quality and battery life.
3Manufacturing precision
If the compression rate of the image is decreased, then the image quality is enhanced, but the battery life shortens due to increased transmission time
Solution Approach 1:
Segmenting image data into multiple packets enables more efficient transmission scheduling and batch processing. This reduces the total transmission time required when using lower compression rates, thereby extending battery life while maintaining enhanced image quality.
Solution Approach 2:
The continuous buffer management system ensures that data packets are continuously prepared and transmitted in an optimized manner. This continuous efficient operation reduces the total time the camera needs to remain active for transmission, extending battery life while allowing the use of lower compression rates for better image quality.

AI summary
A surveillance system in which a network camera communicates with a client device via a gateway is provided. The network camera includes: at least one processor configured to implement a packet generator which generates a plurality of data packets, each including at least one of image data and audio data, and constitute a multi-data packet including the data packets; a memory configured to store at least a portion of the data packets; and an input/output interface through which the packet generator transmits the multi-data packet to a gateway or client device, wherein, in response to receiving an indication that a transmission error has occurred to at least one data packet among the data packets constituting the multi-data packet, the packet generator further generates a target data packet including the data packet from the stored data packets, and transmits the target data packet to the gateway or client device.
