Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing portable media devices face challenges in efficiently selecting and synchronizing media content items with preferred instance attributes across different devices, leading to suboptimal storage and transfer of media content due to varying instance attributes such as digital rights restrictions, bitrate, and file formats.

Innovation Solution

A method for synchronizing media content items between devices involves identifying preferred instances based on differences in instance attributes using a two-dimensional matrix or user-defined rules, ensuring that desirable instances are selected and transferred, while deleting less desirable instances to optimize storage and transfer.

AI summary

The selection of a media content item having preferred instance attributes includes finding a preferred instance of a media content item having two or more different instances by recognizing a first instance of the media content item having a first set of instance attributes and recognizing a second instance of the media content item having a second set of instance attributes. The selection of a media content item having preferred instance attributes further includes selecting either the first instance of the media content item or the second instance of the media content item based on differences between the first set of instance attributes and the second set of instance attributes.
