1. Brief Update August 2016

2. Ultra HD Forum Origins Initially conceived in conversations with EBU in 2012, finally launched at NAB 2015 In 2012 there was a realization that Ultra HD was much more than just 4K and concern that 4K was already penetrating consumer market Addressing the huge potential for confusion and market fragmentation Addressing the deep concerns about backward compatibility and potential format war

5. UHD Alliance + Ultra HD Forum Ultra HD Forum and UHD Alliance are very complementary UHD Alliance is defining a consumer experience quality level through a logo certification program UHD Forum is focused on interoperability, best practice guidelines and advocacy for the end to end ecosystem

10. Key Outstanding Challenges In “normal” circumstances does this tech represent a "wow" change like the SD to HD transition Do we need a higher level of certified "Ultra HD Premium" that takes us beyond 1,000 nits Will bandwidth constraints / caps restrict Ultra HD to a niche Will HLG really provide useable, albeit limited, backward compatibility Will 2 competing EOTFs (HLG and PQ) fragment the market or can both be supported Will licensing issues for elements of Ultra HD technologies constrain content availability Will HDR and SDR mixed content cause consumer issues or will conversion in the CPE mask this Will 709 and 2020 mixed content cause consumer issues or will conversion in the CPE mask this

12. Ultra HD Forum Phase A Guidelines Focus on end-to-end work flows for real-time program streams (aka “linear services”) Live and pre-recorded programming “On-the-fly” assembly of the service –Interstitial insertion and graphic overlays at multiple points in the supply chain Phase A = 2016 –Technologies and procedures that can be used in 2016 Phase A linear services are likely to be delivered via MVPDs and OTT –OTA broadcast services will commence in 2017 in Korea

13. UHD Phase A – Definition Spatial Resolution1080p* or 2160p Color SpaceBT.709, BT.2020 Bit Depth10-bit Dynamic RangeSDR, PQ, HLG Frame Rate**24, 25, 30, 50, 60 Distribution Video CodecHEVC, Main 10, Level 5.1 Audio Format Stereo, 5.1, channel-based immersive audio Audio CodecAC-3, EAC-3, HE-ACC, AAC-LC Captions/Subs Coding (in/out formats) CTA-608/708, ETSI 300 743, ETSI 300 472, SCTE-27, IMSC1 *1080p together with WCG and HDR fulfills certain use cases for UHD Phase A services and is therefore considered to be an Ultra HD format for the purposes of these guidelines. 1080p without WCG or HDR is considered to be an HD format. The possibility of 1080i or 720p plus HDR and WCG are not considered here. HDR and WCG for multiscreen resolutions may be considered in the future. **Fractional frame rates for 24, 30 and 60 fps are included, but not preferred. Lower frame rates may be best applied to cinematic content.

14. UHD Phase A – HDR and WCG Transfer functions discussed: –PQ –HLG “Packages” discussed: –PQ10*PQ EOTF, BT.2020 color gamut,10-bit depth –HLG10*HLG OETF, BT.2020 color gamut, 10-bit depth –HDR10PQ EOTF, BT.2020 color gamut,10-bit depth plus metadata: SMPTE ST 2086, MaxFALL, MaxCLL *Ultra HD Forum terms

15. SDR<>HDR and PQ<>HLG Switching formats may not be seamless in 2016 Normalizing content in a linear service to one “house format” is recommended in Phase A –Program segments, interstitials, graphic overlays at all insertion points 3D LUTs are currently the de facto method –New information about “reference white” levels in conversions are emerging, e.g., 75IRE for HDR Other methods such as SL-HDR1 are emerging for HDR->SDR conversions

16. Mixing HDR with SDR

17. Signaling/Metadata Carriage Signaling transfer function and color space are not currently support in SDI –These can be manually entered at the encoder, which will insert the data into the VUI (suggesting the need for a “house format”) –Care needs to be taken at each decode/re-encode point in the chain since the signaling is “lost” at decode HDR10 metadata carriage needs the same treatment The transfer function and color space MUST reach the display for a reasonable picture –HDR10 metadata can improve the picture, but PQ10 (i.e., no metadata) can also produce a good image

18. Distribution Chain Guidelines covers the following at each point in the chain: –compression technologies –metadata carriage options –audio, captions and subtitles –content manipulation: ad insertion, graphic overlays, etc. –sample bitrate ranges

19. Decoding & Rendering UHD displays handle 2160p resolutions, but may not be capable of HDR or WCG –Backward compatibility for SDR and BT.709 cases discussed Integrated decoder/display for OTT services –Easiest case, since HDMI is not a factor and OTT can offer different streams for different devices Separate decoder/display (STB-Display) for MVPDs –Not all Ultra HD parameters are carried over HDMI 2.0a –CTA-861-G is expected to add support for HLG

20. Backward Compatibility UHD displays are capable of 2160p resolution, but maybe not HDR or WCG –UHD SDR/BT.709 –UHD HDR/BT.709 –HD SDR/BT.709 Options include –Down-conversion at the Service Provider Simulcast and/or SL-HDR1 technology –Down-conversion at the STB HDMI “hand-shake” to discover display capabilities –Spatial up-conversion of HD/SDR/BT.709 content in the UHD device Interoperability of channel-based immersive audio –Atmos using E-AC-3 includes a 5.1 feed for legacy devices

21. Ultra HD Forum Guidelines is a “living document” Revisions are constantly underway as technology develops and matures and service providers work with new techniques Schedule is TBA – goal is to keep pace with the fast- changing industry But Wait… There’s More!
