Background of this proposal

Disney, SPE and Warner Bros. request BDA to support HDR feature in new UHD Blu-ray format. These three studios need both HD with HDR and UHD with HDR.

BDA will define Three new types of Blu-ray discs (UHD, HD with HDR and UHD with HDR). (See picture below)

SDR HDR

HD

UHD

HD HDR stream

UHD stream UHD HDR stream

In addition of the current HDTV and UHDTV, TV manufacturers will provide new UHDTV with HDR (HDTV with HDR??) to enjoy HDR signals from new Blu-ray discs.

Support the current TV (HDTV and UHDTV) user, we need a mechanism to provide some kind (degrading) Video signal from new Blu-ray discs to the current TVs.

Need for Four cases to support for Current TVs Support the current TV (HDTV and UHDTV) user, we need a mechanism to provide

some kind (degrading) Video signal from new Blu-ray discs to the current TVs. UHDTV needs a) UHD HDR => UHD, b) HD HDR => HD cases HDTV needs c) UHD HDR => HD, d) UHD => HD, b) HD HDR => HD cases

Basic assumption and requirements Basic Assumptions The variation of UHD Blu-ray discs are UHD, HD-HDR and UHD-HDR disc. The variation of TV sets are HDTV, UHDTV and UHDTV with HDR All new Blu-ray discs (UHD, HD-HDR, UHD-HDR) will be protected by AACS 2.0 HDR signal (with HDR meta data) will be transferred to UHDTV with HDR by new

HDMI 2.0 or later To support the current TV (HDTV and UHDTV) users, HDR to SDR conversion and UHD

down conversion to HD are needed. a) UHD HDR signals can be converted to UHD signals in new Blu-ray device and these

UHD signals will be transferred to UHDTV by HDMI2.0 with HDCP 2.2. b) HD HDR signals can be converted to HD signals in new Blu-ray device and these HD

signals will be transferred to UHDTV/HDTV by (at least) HDMI1.4 with HDCP 1.4. c) UHD HDR signals can be converted to UHD signals & be down converted to HD

signals in new Blu-ray device and these HD signals will be transferred to (at least) HDTV by HDMI1.4 with HDCP 1.4.

d) UHD signals can be down converted to HD signals in new Blu-ray device and these HD signals will be transferred to HDTV by (at least) HDMI1.4 with HDCP 1.4.

New entries upon AACS review and approval

• AACS will revisit Authorized Digital Output technology for Non-Copying purpose. Two tables will be prepared to address the transition from standard outputs to enhanced outputs. The enhanced outputs include HDCP2.2 and new technology that may be added upon future AACS review and approval. • Content will have the “Standard Digital Output flag”, shown below, in Usage Rules/CCI. Content owners can select the digital output.

Standard Digital Output flag

0 The associated content can be output to the technology listed only on TABLE D2.

1 The associated content can be output to the technology listed on both TABLE D1 and TABLE D2.

Proposal: HDCP Content Type for down-converted stream

Need to add new mechanism to allow Case b), c) & d) to support the current HDTV (HDMI 1.4 & HDCP 1.4) : AACS will introduce New Standard Digital Output Flag (2)

Case b) Down-converted & HDR->SDR converted signal: The HDCP source function must be instructed to treat such content as Type 0 Content.

Case c) HDR->SDR converted stream: The HDCP source function must be instructed to treat such content as Type 0 Content.

Case d) Down-converted signal: The HDCP source function must be instructed to treat such content as Type 0 Content. Otherwise the HDCP source function must be instructed to treat the signals as Type 1 Content.

1 The associated content can be output to the technology listed on both TABLE D1 and TABLE D2.

2 (This proposal) When the content is converted to a format that can be protected with AACS 1.x, i.e. up to HD Resolution with Standard Dynamic Range, that converted content can be output to the technology listed on TABLE D1. Besides above case, The associated content can be output to the technology listed on TABLE D2.
