3. BDA UHD-TF Format Study history & status
2013 Jan ~ Research on next gen Format Extension overall
4K, High Dynamic Range, Wide Color, 3D Audio, & “Digital Bridge (BD content export)”

4K and HDR Video spec, backward compatibility, introduction timing
Simplification of BD Format, Export ready disc format

High level agreement (if possible) on the issues above
Confirm BDA next steps and UHD Format launch timing

4. HDR content backward compatibility
HDR is getting strong interests in industry, especially after CES2014
HDR video signal will be new standard. Compatibility with Player/TV need to be studied.
SPE input to Sony & BDA in past
Avoid the situation where consumers have to match the version of UHD disc to the version of the player. “One UHD Player Spec” reduces this concern.
Any UHD disc to play in any UHD player and produce a satisfactory output (SDR on SDR-TV, SDR or HDR on HDR-TV).
This requires HDR format be backward compatible to SDR system, or requires player to implement well managed mapping of HDR content to SDR signal.
Sony Corp. BDA members suggesting HDR introduction together with 4K in UHD Blu-ray.

TBD whether SDR only UHD player will be licensed or not

5. BDA Format simplification & Export Ready
BDA agreed to simplify UHD BD Format
To focus on main enhancement factors (such as Higher Video Quality, Digital Bridge Export)
Maintain popular BD format functionality
Seamless branching (multi-version movie), BD Java Menu, High quality Audio, etc.
Drop features not widely used, to allow faster/easier player development
Export Ready disc format
Additional files on disc to support export into digital format
E.g. AAC Audio track, Digital format package metadata, etc.
Manifest to identify how export process selects the contents and tracks
HD Blu-ray can be authored in Export Ready style in future
BDA plans to make it optional feature for studios, but may promote it to as default in future.

7. Business & User Experience questions
UHD Blu-ray Digital Bridge Mandatory obligation for studios
BDA and AACS discussing mandatory obligation for UHD Blu-ray Disc (studios)
Have to authorize copies (both BD Format local copy, and Digital File Export)
Multiple DRM support (similar to UV), so that Device Manufacturers can choose DRM
If studios and manufactures could not agree on mandatory obligation on both sides, Sony Corp. thinks obligation can be optional for both studios and manufactures.
Optional means Studios are not obligated to authorize export, UHD BD player may not implement export function. (Use Export scheme only under business base)
UHD Blu-ray Region Coding
BD Player manufactures requesting not to use Region Coding in UHD Blu-ray, especially now studios are requesting Export of Disc contents which will not have player unit based region control anyway. BDA is moving this direction, and 3 other studios (WB, Fox, Disney) agreed to drop region coding.
SPC titles has been using region coding for specific acquisition titles.
Online Key delivery
BDA and AACS studying introduction of online key delivery for UHD Blu-ray to stop pre-street date Disc ripping & piracy.
Sony Corp. BDA members asking whether studios will actually use online key distribution for Disc, and if so, how to mitigate user confusion / frequent customer call.
Online key delivery is part of Hollywood studio next gen security requirements, so majority of AACS companies are supporting introduction of online key delivery system.
