Features SG Chair’s understanding on Hollywood Studio
Hollywood studios have their own “Digital” strategy to meet the current U.S. market. Increasing digital sales (Electronic Sell‐Through: EST) is required to make up for a
fall of package sales. However, Apple dominates the market (see figure EST on the lower‐right), followed
by threatening Amazon. The studios except Disney are doing UV (DECE) to support of Blu‐ray sales (provision of
contents for mobile as an added bonus of Blu‐ray) and promotion of EST. They think one common ecosystem/format for both EST services and Blu‐ray Bridge
are essential to explosive diffusion of Digital Content Business.

Chair’s understanding of use case of BDA Bridge
By appealing for a) Home movie library and b) Bridge to mobile devices (e.g. tablet) to users after converting Blu‐ray contents (UHD/FHD) into industry standard format (SFF:Standard File Format), Hollywood Studios are aspiring to accelerate the expansion of c) EST business by promoting SFF ecosystem.
The studios decide to set up one industry standard format and one ecosystem for both EST and Blu‐ray Export/Bridge.

Record labels
Reference: Apple Music World (Disc & Digital)
Apple created total Music ecosystem from CD export functionality (respect user‘s music assets: “CD collection”).
Users enjoy music by using both Music server (iTunes) and Portable music devices (iPod & iPhone)
Even Apple store (Music download) is very popular, but most music content in Music server (iTunes) still came from CDs.

Potential ideal digital movie ecosystem
Considering Apple Music ecosystem, interoperability among EST services, BD export, Home Movie library and Portable devices is essential for total movie eco‐system. One Standard File Format : SFF (including Common encryption) is important
But there are many EST services exist and each studio may have deferent idea. Can we/BDA agree this basic concept? How can we/BDA make it happen?

A Goal of SFF ecosystem SFF compliant content are used in various EST services and various SFF
players on hardware and software systems. (HW/SW). The proposed BDA-SFF implementation will support File Export functionality
only with no elementary stream transcoding (No trans-crypting?).

Concern 1: Export to WHOM?How can user understand this unknown functionality in the UHD Blu‐ray player? How to explain to user about this Bridge functionality and SFF data?
User Experience is Key factor of success:Several concerns from the UHD Blu‐ray device users’ view points=> How to realize Simple, Easy, Understandable User experience
Concern 2: Export speed?How long does export take in UHD Blu‐ray player?
Concern 3: Playback of Export content in UHD playerHow can user use (or even verify) this exported SFF content in the UHD Blu‐ray player?

UHD, new and legacy Blu-ray disc UHD Blu-ray device will handle these three types of discs1. UHD Blu-ray disc: BDMV-FE and New data for supporting Export2. New Blu-ray disc: No change for BDMV, but New data for supporting Export3. Legacy Blu-ray disc:No change for BDMV nor new data.
How to realize “Export” for Legacy Blu-ray disc? “Data for Export” for legacy Blu-ray should be prepare in a Web site (Studios’ or BDA?)

Use case of UHD Blu-ray disc (Packaging)
Reference: 3D Blu-ray One of key Blu-ray 3D feature/concept is 3D/2D compatible disc, so BDA
introduced new MVC for 3D (compatible with 2D AVC playback device)

Use case of UHD Blu-ray disc (Packaging)
Reference: 3D Blu-ray Most 3D SKU has 3D only disk and 2D Blu-ray disc (3D only + 2D SKU) No need 3D/2D compatible disc concept If we understood this, then Blu-ray 3D format must be more simple and no need
to huge investment for development for devices, Authoring, Verification, etc.

Use case of UHD Blu-ray disc (Packaging)
UHD Blu-ray disc only for UHD Blu-ray Device, must NOT play on current Blu-ray device. (We have already agreed) => No need UHD/Blu-ray compatible disc.
We can expect that UHD SKU should include the current Blu-ray disc. UHD format should be simple (focus on UHD and Bridge use case), then no need to huge investment for development for devices, Authoring, verification, etc.

Concern: How and who defines SFF BDA-SFF can be defined by BDA, but SFF should be used many services and
devices. At least BDA, UV and other major EST servicer should be involved.– Who can define, maintain, own and license of SFF spec?– Can we agree to basic requirements and design direction by BDA?– Can we agree relationship between MP4, SFF, CFF and BDA-SFF with out
side BDA organazations?– Can we agree minimum set of SFF for SFF player(software and device)?– Can we agree one common encryption scheme?– Can we agree multiple DRM support and its infrastructure for SFF?

SG chair’s request
BDA BoD three studios’ opinions and Business intention might be different.
To understand Studios Digital Broadband business and Blu‐ray business, I would like to get and share non BoD studios’ opinion & comments which will enhance the clout of TF recommendation.
I request to UMDTF members, I would like to invite key person who involved Digital distribution and Blu‐ray from Universal Pictures and/or Paramount pictures to Features SG and other SGs as deemed necessary.
At least, for Universal, Universal is a contributor member company, so we do not need to make special NDA to this activity, like a MediaTek.
