Content Package Dual Representation for Media Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems lack a mechanism for providing a file container that can be readily modified and rendered by a user, requiring re-authoring or reformatting of files after download, and do not offer efficient storage and playback of audio and video content.
Innovation Solution
A content package system that includes both physical and logical representation data, allowing for storage, download, and playback of media files, enabling direct access and playback without extraction, and supporting multiple formats, resolutions, and encryption schemes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If existing file container systems (zip, tar, cab) are used to group multiple files, then files can be stored and transmitted efficiently, but the obtained files require re-authoring or reformatting before storage or playback
Solution Approach 1:
The patent introduces a dual representation system where physical representation data serves as an intermediary layer between the raw file container and the user's playback needs. This intermediary layer automatically translates and adapts the packaged files into formats suitable for direct playback, eliminating the need for manual re-authoring while preserving the efficient packaging benefits
Solution Approach 2:
The system changes the representation parameters of the packaged files by maintaining both physical representation data (original format) and logical representation data (playback-friendly format). This parameter transformation allows the same packaged content to serve both efficient storage and direct playback requirements without manual intervention
2Productivity
If files are packaged in generic containers, then storage and transmission efficiency is improved, but user modification and rendering capability is reduced
Solution Approach 1:
The patent creates a universal file container system that serves multiple functions simultaneously: efficient storage, direct playback, and user modification. The dual representation system allows the same packaged content to be read by different systems (players, editors, viewers) without requiring format conversion, making the container universally adaptable to various user needs
Solution Approach 2:
The patent adds a dimensional layer by introducing logical representation data alongside physical representation data. This additional dimension enables the system to provide both the efficiency of packaged storage and the flexibility of user modification, as the logical layer can be selectively accessed or modified independently of the physical container structure
3Ease of operation
If media files are accessed through extraction, then direct access to individual files is enabled, but system complexity and processing time increase
Solution Approach 1:
The system performs preliminary action by pre-processing and pre-organizing the packaged files into both physical and logical representations during the packaging stage. This preliminary organization eliminates the need for complex extraction and reformatting operations during playback, as the logical representation is already prepared and ready for direct access

AI summary
Defining a content package having media files and table of contents (TOC) data. The content package includes physical representation data and logical representation data for the media files (e.g., stored in the TOC data). Computing devices store, download, and play back the media files based on the data in the content package. Presentations (e.g., collections of files) within the content package are available for extraction based on a configuration of a media player. The media files are provided for presentation to a user of the computing device, or for storage by the computing device.
