Adaptive Content Delivery System for Dynamic Format Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for multimedia content on the Internet leads to high storage and bandwidth requirements, resulting in wasted bandwidth and increased costs due to the need for multiple copies of video files in different formats and resolutions, as well as difficulties in managing and updating these files.
Innovation Solution
A system that dynamically adjusts the characteristics of downloaded content, such as bit rate, format, and resolution, based on the attributes of the client device, using an adaptive data processing system to intercept and modify content requests and responses, ensuring optimal delivery and reducing unnecessary storage and bandwidth usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple copies of video files are stored in different formats and resolutions, then content compatibility with various electronic devices is improved, but storage requirements and bandwidth usage increase
Solution Approach 1:
The patent implements a universal content delivery system where a single video file can be dynamically adapted to serve multiple device types and formats. The system analyzes client device attributes and transforms the content accordingly, allowing one source file to fulfill multiple format requirements rather than storing separate copies for each device type.
Solution Approach 2:
The system dynamically changes content parameters (format, resolution, bitrate) based on the requesting device's attributes. By modifying these parameters in real-time during content delivery, the system achieves format adaptability without requiring pre-stored copies in each format, thus reducing storage requirements while maintaining compatibility.
2Adaptability or versatility
If multiple copies of video files are stored in different formats and resolutions, then content compatibility with various electronic devices is improved, but bandwidth usage and costs increase
Solution Approach 1:
The system extracts only the necessary format adaptations from a single source video file and applies them during content delivery. Instead of transmitting multiple pre-converted versions, the system extracts and applies only the specific format, resolution, and codec transformations needed for each individual client device, thereby reducing bandwidth consumption.
3Reliability
If the entire video file is downloaded to the client device, then video playback quality is improved, but bandwidth waste increases when only a small portion is viewed
Solution Approach 1:
The patent segments the video content delivery process to match client device capabilities and viewing requirements. By analyzing device attributes and playback conditions, the system delivers appropriately sized and formatted video segments rather than requiring complete file downloads, thus maintaining acceptable playback quality while reducing bandwidth waste for partial viewing scenarios.

AI summary
According to one embodiment of the invention, a method is devised for tailoring downloaded content to the requesting device by receiving attribute parameters associated with a device that initiates a request for downloaded content. The attribute parameters are values that identify specific characteristics of the device. Thereafter, the content is modified according to the attributes parameters, and thereafter, the modified content is transmitted to the device.
