Sony Confidential page | 1

Overview• This document describes Sony UHD Blu-ray format

proposal with high level requirements, examples of technology candidates, and study items.

• Sony reviewed FEST study result and integrated / referred FEST recommendations where they can be applied.

• Since Sony believes there are several issues that require BoD level further study, Sony proposes to create study group (UHD-TF) focusing on the study items identified in this document.

• Study will establish the baseline of most used BDMV format functions (Core BD functionality).

Part1: Physical Specification1. Recommends 50GB, 66GB and 100GB capacity discs.

2. Recommends that JTC/TEG6 will recommend physical maximum data rate for each disc taking into consideration the impact on physical specifications/disc manufacturing, player design and behavior of legacy drives.

– Recommends that the JTC/TEG6 study physical maximum data rates with a target of 3X BD for the 50GB disc and 4X BD for the 66GB and 100GB FE discs.

3. Following the conclusion of the JTC/TEG6 physical maximum data rate recommendation, BoD level TF (TBC) makes the final decision on maximum data rate for the FE discs based on

a) JTC/TEG6 recommendation of physical maximum data rate

b) AV application data rate requirements

Same as recommended by FEST/DCSG

Part2: File System Specification

1. UDF 2.5 (same as HD BD-ROM Spec)

2. May need to update requirements for AV Application Use, to adapt proposed new AV format.

• Sony expect this work is straightforward, and can be handled in JTC/TEG5 when AV format is concluded.

No study required in BoD level TF

Part3: Audio Visual Basic SpecificationCore AV Playback

• High level requirements

– A media file format that can be delivered on a UHD disc, by download or other means. That media file can be played back on UHD players and on other devices.

– An optimized mapping of the file to the structure of a Blu-ray disc (for example, optimized for seek times, layer jump etc.) providing the same playback performance the consumer expects from a Blu-ray disc.

• Candidate Technologies

– A media format similar to Common File Format, etc.

– May require extension of existing format to adapt UHD specific requirements, or work with other standard body to incorporate UHD requirements to existing standard.

• Study Items:

– Establish the baseline of most used BDMV format functions (Core BD functionality) and Create new UHD BD Core functionality list

– Mandatory feature: Video/Audio/Subtitle, Trick Play, Chapter Skip, Smooth playback over layer jump

– Need study of the necessity of additional AV playback features considering the actual Blu-ray disc consumer benefits and consistency with the usage of same file formats on the other delivery method.

– Optimized AV playback performance of proposed new media file format when played back from optical disc.

Part3: Audio Visual Basic SpecificationInteractivity


– Introduce an open execution platform such as an HTML5 browser for future player profiles.

– There will be 2 profiles of players envisioned. A simple profile player that supports core BD functionality using simple HTML5 document structure, as well as a full interactivity profile which will offer content providers and device manufacturers an innovative environment to provide consumer experiences far beyond the use cases of BDMV Format discs.

• Candidate Technologies, proposed profile structure:

– Open execution platform such as an HTML5 browser

– 2 Profiles of player

– “Simple profile” (Core BD functionality, mandatory for all UHD BD Player)

– “Full Interactivity profile” (optional for player, provides environment which keeps expanding use cases)

– UHD BD Content must provide at least Core BD functionality on both types of players, and may additionally provide richer interactivity/application for Full interactivity player.

• Study Items:

– “Simple profile” format, and its player implementation feasibility.

– Study how to deliver additional “Full Interactivity”, utilizing the same open execution platform scheme adapted for simple interactivity.

Sony Confidential

FEST/FSG discussion result is not directly applicable.

Part3: Audio Visual Basic SpecificationLate Binding


– An extensible file format that supports late binding – the ability to add new content at a later time (e.g. director’s commentaries, other language tracks, additional video content, etc.)


– Late Binding Specification, etc.

• Study Items:

– Use pre-defined Codec and File Format to deliver additional content

– New late binding method should provide better performance (less waiting time) than VFS Update currently used in BDMV Format.

– Study if late binding can be applied to “Simple profile” player.

– Late Binding for “Full Interactivity” is supported only by the player with “Full Interactivity”.

Similar feature exists as “BD-Live” in current BD Format. Suggest re-defining this feature to be applicable to proposed file/application format.

Part3: Audio Visual Basic SpecificationUHD Video Specification Remaining Item


– Future support within the format for high dynamic range (HDR) and wide color gamut content is anticipated. Recognizing that it may be necessary to launch with players that have standard dynamic range, HDR content backwards compatibility on standard dynamic range systems and necessary bit depth need to be studied.


– SDR Video: HEVC, 10bit, 420, BT.2020 for SDR UHD content

– HDR Video: to be defined

• Study Items:

– HDR Video specification

– How to deliver HDR Video keeping backward compatibility with SDR-only UHD BD Player

– Other remaining study items recommended by FEST/VPSG (e.g. Metadata, Frame Rate, Gfx blending, peak Video bitrate study)

SDR Spec based on FEST/VPSG recommendation. FEST/VPSG recommended further HDR study(Ref. next page for HDR Video backward compatibility issue.)

Recap from FEST/SG discussion

• No supermajority on several key issues:

– FEST: Digital Bridge Function (studio proposal)

– Video Performance SG: Video parameters

– Feature SG: 2nd screen related proposal

• Further study Items suggested to be taken over:

– Video: High Dynamic Range

– TV/Player IF : Metadata for High Dynamic Range and Wide Color Gamut

– Physical: Larger disc capacity & higher data rate

– Graphics layer study

Due to the limited amount of time given to the FEST Gp., FEST recommendation to the BoD was based on a simple majority opinion, and included items which could not be supported by many BoD companies.

BoD disapproved FEST recommendation (8 Yes, 9 No, 1 Abstain)


Study after Berlin meeting

• Wider Scope Study:

– 4K/UHD not only for Blu-ray

– Industry landscape, background of studio request on certain features

– How Sony can come up with a new approach which would be able to achieve wider support in the BDA

• The facts:

– New 4K/UHD format needs support from content companies

– There have been significant technology advancements since the BDMV Application format has been developed (2004~2005)

– BD Physical Disc still has the advantage of being low cost with reliable bit delivery

– 4K is already in the market today. BDA needs to act quickly to catch up, and expand the use of the 4K/UHD format for consumer, industry, and the BDA


Landscape / BackgroundMany content consuming devices out in the market

BDA43 meeting in Bangkok• During BDA43 week:

– After gathering feedback from BoD companies, Sony would like to present more details on the new approach outlined in today’s presentation. F2F meeting style would be most efficient for this discussion.

– Based on those F2F discussions, Sony hopes that the BDA will be able to find productive next steps to be presented to the BoD. (such as creation of study groups focusing on the new approach proposed by Sony, and other remaining key issues)
