Innovation Solution
An image providing apparatus and method that includes a storage unit, transceiver, and controller to extract format information of receiving devices, process images accordingly, and transmit them in optimized formats, along with user interfaces for manipulation, to ensure compatibility and efficient display on external devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the DVR uses a single encoder to compress images in a single format, then the device complexity is reduced, but the adaptability to different external devices deteriorates
Solution Approach 1:
The server acts as an intermediary between the DVR and external devices. The DVR sends images in its native compressed format to the server, which then decodes and re-encodes them into formats suitable for specific external devices. This mediator approach allows the DVR to maintain simple single-format encoding while the server handles format conversion to ensure compatibility with various external devices.
2Adaptability or versatility
If the external device receives images from multiple DVRs using different encoders, then the versatility of the external device is improved, but the data processing load on the external device increases
Solution Approach 1:
The server serves as a preprocessing intermediary that performs format conversion before images reach the external device. Instead of requiring the external device to decode multiple different encoder formats, the server converts all incoming images from various DVRs into a standardized format that matches the external device's requirements, thereby reducing the processing burden on the external device.
Solution Approach 2:
The format conversion and optimization process is performed in advance by the server before transmitting images to the external device. This preliminary action ensures that images are already in the appropriate format when received, eliminating the need for the external device to perform complex decoding operations on multiple different formats.
3Ease of operation
If the external device has low data processing capability, then the ease of operation is improved, but the ability to process multiple image formats deteriorates
Solution Approach 1:
The server acts as a capability-compensating intermediary that performs format conversion on behalf of external devices with limited processing power. The server analyzes the external device's capabilities and converts images into appropriate formats that the device can handle easily, thereby maintaining both ease of operation and format adaptability.

AI summary
An image providing apparatus, an image displaying apparatus, an image transmitting system and an image transmitting method thereof. The image providing apparatus includes a storage unit, a transceiver to receive transmission request information and a stored image, and a controller to process the image using extracted information. Accordingly, a waste of resource required for data processing at an external device is reduced and an image optimized for display is provided to the external device.
