FIELD: information technology.
SUBSTANCE: image container file has at least first and second multimedia streams (MS). The first MS includes first image data representing an image. The second MS includes arbitrary data which can correspond to: a different representation of the same image; annotations to the first image data; second image data that together with the first image data form a new image with greater dynamic range, resolution, field of view or other attributes that can be derived from processing two or more independent images; or an executable file related to the first MS. The image container file can also include extensible metadata to hold information describing one or more multimedia streams of the image container file, as well as DRM information for obtaining a license to access encrypted data or verifying the authenticity of encrypted or unencrypted data.
EFFECT: providing, when creating an image container file, functional linkage of multiple multimedia streams, one of which is received by a receiver and the other includes arbitrary data.
