Video File Size Reduction for Handheld Device Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for managing video data on handheld devices are inefficient in reducing file size and transmitting video content effectively, particularly in wireless networks, leading to high memory usage and poor user experience.
Innovation Solution
A method involving a Digital Video Recorder (DVR) that receives requests to record and send television programs or videos, reduces their size by compressing or lowering frame rates, and transmits the reduced-size representations to handheld devices via wireless links, utilizing detachable storage media for efficient storage and transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If video data is transmitted to handheld devices without size reduction, then video quality is maintained, but memory usage increases and transmission efficiency decreases
Solution Approach 1:
The patent applies parameter changes by modifying video encoding parameters such as bitrate, resolution, and frame rate to reduce video file size. The system adjusts these parameters dynamically based on the handheld device's capabilities and network conditions, achieving optimal balance between file size reduction and video quality maintenance.
Solution Approach 2:
The video data is segmented into smaller manageable units suitable for handheld device storage and transmission. The system divides large video files into segments that can be efficiently transferred over wireless networks and stored in limited memory spaces of portable devices.
2Quantity of substance
If video data is compressed to reduce file size, then memory usage decreases, but video quality deteriorates
Solution Approach 1:
The system optimizes encoding parameters to achieve efficient compression while preserving video quality. By carefully selecting compression ratios, bitrate, and encoding standards, the patent maintains acceptable video quality while significantly reducing file size for portable device compatibility.
3Manufacturing precision
If high-resolution video is transmitted over wireless networks, then video quality is maintained, but bandwidth consumption increases
Solution Approach 1:
The patent dynamically adjusts video transmission parameters including resolution, bitrate, and frame rate based on available network bandwidth. This allows the system to maintain acceptable video quality while adapting to varying wireless network conditions and minimizing bandwidth consumption.
