Media File Resolution Upgrade via Sample Ratio Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face increased storage requirements when upgrading media files from low resolution (e.g., 16 bits/sample) to high resolution (e.g., 24 bits/sample) as they need to store both versions, leading to inefficient storage usage.
Innovation Solution
A device and method that divides high-resolution data samples by corresponding low-resolution samples to create intermediate data samples, which are stored instead of the high-resolution samples, optimizing storage usage by reducing the size of the data required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users store both low-resolution and high-resolution media files, then both resolutions are available for use, but storage space requirement increases significantly
Solution Approach 1:
The patent creates a compressed representation (third media file) that serves as a mathematical copy of the high-resolution data. By storing the ratio between high-resolution and low-resolution samples instead of the full high-resolution data, the system achieves significant storage reduction while maintaining the ability to reconstruct high-resolution output when needed.
Solution Approach 2:
The third media file containing ratio data is nested within the existing low-resolution media file structure. The system stores the low-resolution file and a compressed ratio file together, where the ratio file contains the essential information needed to generate high-resolution output without requiring separate full-size high-resolution storage.
2Measurement precision
If users upgrade to high-resolution media files, then media quality improves, but storage resource usage increases
Solution Approach 1:
The patent changes the parameter representation by storing the ratio between high-resolution and low-resolution samples instead of storing the full high-resolution samples. This parameter transformation allows the system to achieve high-resolution quality output while using significantly less storage space, as the ratio data requires far fewer bits than the original high-resolution data.
3Measurement precision
If users replace low-resolution files with high-resolution files, then media quality improves, but compatibility with existing low-resolution playback systems may be affected
Solution Approach 1:
The patent implements a dynamic playback system that automatically adapts to the playback device's capabilities. The playback device determines whether it supports high-resolution playback and accordingly processes the stored files - either playing the original low-resolution file directly or using the stored ratio data to generate high-resolution output, ensuring optimal compatibility and quality for each device type.
Data Source
AI summary
A device of updating a media file for an increased resolution includes an I/O interface, a processor, and a storage device. The I/O interfaces acquires a first media file having first data samples and a second media file having second data samples. Each first data sample is sampled from an analog media signal and encoded with P bits and each second data sample is sampled from the analog media signal and encoded with Q bits, wherein “P” and “Q” are integers, and a resolution in bits of Q is greater than a resolution in bits of. The processor divides each second data sample by a corresponding one of the first data samples to calculate third data samples. The storage device stores the calculated third data samples as a third media file.
