OVERVIEW

• IMF is envisioned as a file-based Mezzanine Master Source which would serve a

similar function as the HD Video Master does today at the front end of the client deliverable chain, with additional benefits.

• Use IMF to ingest content into to our internal Distribution Backbone (DBB)
• Send to our servicing vendors as their source to service client orders
• IMF essence should be the at the highest quality level necessary to meet and

exceed any client deliverable that is envisioned for the foreseeable future.

• IMF itself is not envisioned as a client deliverable, all deliverables would be made

via transcoding or other process to client specs.

• IMF with uncompressed picture may be utilized for internal archiving in the future.

IMF PROCESS

IMF is envisioned as an additive process:

• A “Base” IMF is created of the original version of the program that contains:
• O.A.R. picture
• Native language audio in 5.1 and Lt-Rt (and 7.1 if applicable)
• Music and Effects and M+E optional material in 5.1 and Lt-Rt (and 7.1 if applicable)
• Original subtitled text
• CPL
• OPL “Base” that contains content specific preferences (TBD)
• Additional “Partial” IMF’s are created as needed and as material becomes available,

and contain only:

• Unique, additional or substitute content
• CPL that plays content from base IMF and partial IMF as needed to create the intended program
• OPL, inherited from “Base OPL” and modified as needed

IMF PROCESS

• Examples of additional IMF’s:
• Additional picture resolutions
• Foreign Localized
• Alternate Cuts, e.g. Unrated, Director’s Cut
• TV/Airline Versions
• IMF’s are stored internally and at servicing vendors
• Each new partial IMF is added to the storage, and the stored content directory for that title grows

accordingly.

• If a complete IMP is required, then all applicable essence is placed in the package from the base IMF

and the partial IMF.

• To service a client order:
• OPL for requested version is utilized to call the CPL for that version, which in turn calls the essence to be played from

the storage

• CPL plays the program content
• OPL is combined with client preferences to create output (TBD)

MASTERING USE CASE

• It is envisioned that at the start, the mastering process will create

separate picture files for each of required resolutions e.g. 2.40. 1.78, 1.33

• The O.A.R. picture file will be in the “Base” IMF
• Other picture resolutions will be in “Partial” IMF’s
• In the future, we will want to allow the IMF to have much higher resolution

picture essence and utilize metadata and dynamic metadata to obtain the desired resolution

VERSIONING USE CASE

• Versions will be created as partial IMF’s
• After the approved version is created in a workstation, the unique items are
• utput to a “versioned” partial IMF.
• The versioned IMF’s are stored with the base IMF and other partial IMF’s
• To play the complete version, the OPL for the requested version is utilized to

call the CPL for that version, which in turn calls the essence to be played, which will be from the base IMF and the versioned IMF.

• If a complete versioned IMP is required, then all applicable essence is placed

in the package from the base IMF and the versioned IMF.
