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)”– BDA discussed introduction of digital file format for UHD BD Disc delivery, but decided to study

use of existing BD AV Format requiring player to export digital file format from disc.

• 2013 Dec ~ – BDA UHD TF focusing on 4 issues, targeting 2015 Launch

• 4K and HDR Video spec, backward compatibility, introduction timing• Simplification of BD Format, Export ready disc format• Digital Bridge Export Format (compatible with DECE format)• Digital Bridge rules (mandatory obligation for content provider and player)

– AACS (content protection for current HD/3D Blu-ray) working on next gen security for UHD BD

• 2014 Mar BDA F2F (3/10-15)– High level agreement (if possible) on the issues above– Confirm BDA next steps and UHD Format launch timing

• 2014 July ~ early 2015: BDA F2F meetings (3 times a year)– Technical specification, licensing, tools to be finalized for support UHD Blu-ray launch

• 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.

Idealcompatibility

TBD whether SDR only UHD player will be licensed or not

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.

Business & User Experience questions1. 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)

2. 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.

3. 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.
