MIME Type Parameters for Derived Image Composition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The ISO Base Media File Format (ISOBMFF) lacks consideration for derived images in its MIME type specification, leading to inefficiencies in determining the required codecs and resources needed for rendering, particularly for image players that may waste time assessing capabilities before composing derived images.
Innovation Solution
A method is introduced to assess the capability to compose derived images by including additional MIME type parameters such as 'dimg-instr-set' and 'codecs' that specify the instruction sets, codecs, and resource requirements, allowing players to determine if they can reconstruct derived images without unnecessary file downloads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the ISO Base Media File Format specifies MIME types without considering derived images, then the format maintains simplicity and broad compatibility, but players waste time assessing capability to compose derived images before rendering
Solution Approach 1:
The patent applies preliminary action by including capability information in the MIME type parameters before the player needs to assess derived image composition capability. The 'dimg-instr-set' and 'codecs' parameters provide advance notice of required instruction sets and codecs, allowing players to determine compatibility immediately without time-consuming assessment of derived image composition capability.
2Productivity
If the MIME type specification includes detailed parameters for derived images, then players can efficiently determine rendering capability, but the specification becomes more complex
Solution Approach 1:
The patent applies parameter changes by extending the MIME type syntax to include specific parameters ('dimg-instr-set' and 'codecs') that convey derived image composition requirements. This allows efficient capability determination while maintaining a structured, standardized parameter format that integrates with existing MIME type frameworks.
3Reliability
If players download additional files to assess derived image capability, then rendering accuracy improves, but resource usage and processing time increase
Solution Approach 1:
The patent applies the extraction principle by removing the need for players to download additional files to assess derived image capability. The required capability information ('dimg-instr-set' and 'codecs' parameters) is extracted from the media file metadata and included directly in the MIME type declaration, allowing players to determine rendering capability from the existing file information without additional resource consumption.

AI summary
A method comprising: receiving a first description of a first file, the first description including properties of at least a derived image included in or referred to by the first file; determining, based on the properties of the derived image, whether to obtain the derived image; and in response to determining to obtain the derived image, obtaining the first file comprising the derived image.
