Nor. Dig T report - T F A DR Nor. Dig Excom meeting • Video dynamic HDR 10 th October 2019 Stockholm, Sweden Background: Dynamic metadata High. Dynamic. Range (d. HDR) and High. Frame. Rate (HFR): • Investigating as Excom asked Oct 2018: • • • Members interest now 2019 for HFR and/or dynamic HDR (should Nor. Dig add both or one of them? ). If dynamic HDR is recommended, then should it be included as a new IRD “profile” (two Nor. Dig HEVC “profiles” (basic HEVC and d. HDR HEVC IRD) or extent the existing HEVC IRD “profile” (with a certain grace period)? If dynamic HDR, how many of DVB three alt to be included? Which one if not all? As earlier Nor. Dig based upon DVB spec, only variants inside coming DVB specs is relevant here. Excom meeting March 2019: • HFR: low interest right now to introduce -> postponed • • d. HDR: interest but Excom to investigate members concrete interest and demands, d. HDR: technical group study more, too early to start drafting, commercial requirement should be updated (old commercial requirements used for HEVC&NGA) Under discussion today static HDR (both HLG 10 & PQ 10) SFR up to 50 fps e. g. 1080 p 50 fps d. HDR 6

Nor. Dig T report - T F A DR Nor. Dig Excom meeting Video dynamic HDR 10 th October 2019 Stockholm, Sweden Dynamic metadata HDR (d. HDR) • • • DVB d. HDR status: spec finalized, DVB/ETSI spec published, DVB prepare reference streams f d. HDR (OTT) DASH d. HDR status: under publication prel w 3 month ETSI spec DVB has included 3 d. HDR technologies/formats, all HDR PQ 10 based: • Technicolor/Philips SL-HDR 2 (ETSI TS 103 433 -2, SMPTE ST 2094 -20 Philips & 2094 -30 Technicolor formats) • Samsung HDR 10+ (SMPTE ST 2094 -40) • Dolby Vision (ETSI TS 103 572, SMPTE ST 2094 -10) (Note: all three d. HDR candidates been present in Nor. Dig-T/video subgroup meetings) All 3 d. HDR formats are backward compatible for static HDR/PQ 10 IRDs to receive and display (up to broadcaster/colourist to ensure performance for static HDR HEVC IRDs). HLG d. HDR, • work ongoing in ETSI (JTC broadcast group) for Technicolor/Philips SL-HDR 3, Dolby mention already support but not promoted (since DVB so far been for PQ). • Conversion possible from HLG d. HDR to PQ d. HDR within same format (Technicolor/Philips SL-HDR 3 to SL-HDR 2) d. HDR bandwidth • All formats has low extra capacity (in magnitude of 100 kbps or less) • supports of “simulcast” several d. HDR metadata formats for one and the same video stream in (DVB requirement, so far not yet tested) • • Indication/example, SL-HDR 2 typically around 1 -15 kbps Nor. Dig-T/video has not (yet) compared the 3 formats (pros&cons, relative efficiency, IPR costs…). d. HDR already used in some OTT/Online streaming services (e. g. Netflix, Amazon, Apple, multiple formats used) and available in some TV sets (even if it might not yet impl as coming DVB signalling for d. HDRs). (Note, we can not expect that current d. HDR impl on TV sets will work for broadcast usage or DVB DASH streaming). Conversion from one d. HDR format to another, could harm “artistic intension” from colourist, content owner/broadcasters may not allow this, no “approved” method today. 7

Nor. Dig T report - T F A DR Nor. Dig Excom meeting • 7 th Video dynamic HDR March 2019 Stockholm, Sweden Members view (broadcasters and operators) • SVT, DR & NRK: • - d. HDR, right now more interest than HFR and UHD, d. HDR could make big difference espec for drama production, d. HDR roll-out could for example be first via OTT streaming and later within broadcast, d. HDR too early today to select one of the formats, d. HDR could accept that this would be optional tool for IRD (initially), (but big interest among broadcasters - backward compatibility is of interesting TV format: 1080 p 50 fps d. HDR - DR: - • • for d. HDR than Nor. Dig should mandate d. HDR w grace period) HFR 100 fps could accept wait and revisit topic later, a bit challenging to produce right now SVT/Lars typical future production could be: drama 2160 p 25 fps d. HDR and sports/general 1080 p 100 fps SDR/HDR. Difficult for PSB to choose exclude viewers due to only select one d. HDR tech As DR understand it today: Static HDR not as big step for viewers to SDR compared to d. HDR, therefore interest in basic SDR/HLG Test streams: some interest to collect test streams TDC: follow broadcasters, CD: some interest depends upon broadcasters Preferebly if Nordic & Irish broadcasters could agree upon a common d. HDR format (for production). Propose to make a study around d. HDR to find a common d. HDR among broadcasters. new tools w HEVC: Nor. Dig broadcasters interest (2017 Nor. Dig work) If d. HDR format, then the decision of which d. HDR format should be done productions side and not on the IRD side ? Figure: data from Nor. Dig T/video HEVC study 2017 and questionnaire. Note about Full. HD, refers to as subresolution UHD BT 2020 10 bits HDR WCG d. HDR HFR Full. HD UHD 1080 p 2160 p 8

Nor. Dig T report - T F A DR Nor. Dig Excom meeting • 7 th Video dynamic HDR March 2019 Stockholm, Sweden Industry view • d. HDR, most TV manufacture prefer d. HDR is optional feature in Nor. Dig. • d. HDR, if Nor. Dig would add d. HDR (as mandatory), than most manufactures request only one d. HDR format and not require all 3 formats, similar NGA • Samsung, TP Vision prefer markets decide themselves (i. e. not specified in Nor. Dig? ) • d. HDR already in some TV sets, already used for some services, smaller step than HFR • d. HDR, manufactures asks for service plans/roll-out plans from broadcaster to consider this. Nor. Dig should collect from members/broadcasters and regular present/provide service plans and intensions to the Industry. (Sony) With all improvement in video processing and display in new modern TV sets, reduces the diff betw s. HDR and d.

Nor. Dig T report Nor. Dig Excom meeting 10 th Accessibility report status (1/4) October 2019 Stockholm, Sweden Not updated Investigate members usage of accessibility features and how it is signalized within the Nor. Dig area (audioand subtitle- languages, dubbing, spoken subtitles, sign languages and more). Make an overview. (Full report in Annex B of this presentation). Mission • To understand the current state of accessibility services across the Nor. Dig region • To survey the members and gather feedback • To find the pain points in workflows • To find possible pain points in the customer experience • To learn if the technologies specified in the Nor. Dig specification are being used • To find our why certain technologies are used or not used Questionnaire Jan 2019 Questions asked to what extent the following accessibility / disability services types are used today: • Audio Description (AD) • Spoken subtitles (audio captioning) • Same-language Subtitles (captioning) / Hard-of-Hearing Subtitles (Ho. H or HHS) • Sign Language Description (video) • Common questions (Prime time in this questionnaire was defined from 19: 00 to 23: 00 every day, may differ in countries) 19

Nor. Dig T report Nor. Dig Excom meeting Not updated 10 th Accessibility report status (2/4) October 2019 Stockholm, Sweden Conclusions 1 The use of accessibility in broadcast services • More requirements and guidelines for accessibility are expected to be drafted as a result of the EAA and AVMS Directives (EAA = European Accessibility Act and AVMSD = Audio visual media services directive) • It was identified that in many cases, except “Same Language Subtitles”, the provision of Accessibility services was lower than ideal, although always meeting minimum regulations, this may be because of several reasons: – Broadcasters want everyone to be able to receive their services, so transmission is done the simplest way which may not always be the most spectrally efficient or the best use of available technology. – There is a perception that legacy receivers may cause problems are preventing broadcasters from launching new services or using new features. 20

Nor. Dig T report Nor. Dig Excom meeting Not updated 10 th Accessibility report status (3/4) October 2019 Stockholm, Sweden Conclusions 2 The use of accessibility in broadcast services • Pre-testing of Accessibility features on receivers (typically based upon Nordig testplan) may not always catch all problems and broadcaster use-case. (Some functionality like receiver mix is used outside Nordig area) • Re-testing of new Accessibility features on legacy receivers is likely to be expensive and broadcasters need to have a simple launch program. • Broadcasters tends to use other types of broadcast technology than those recommended in Nordig/DVB, like setting up separate services for new accessibility features. • Broadcasters do not prioritize informing consumers about their accessibility services and how to find them on different IRDs. • Conclusion: We have a common spec, but all broadcasters are doing things their own way. 21

Nor. Dig T report Nor. Dig Excom meeting Not updated 10 th Accessibility report status (4/4) October 2019 Stockholm, Sweden Next Steps • The Nordig Accessibility group should prepare a short document explaining the work of the group and ask Ex. Com members to pass this to their internal accessibility teams. – Invite them to contribute and ask questions. – We propose a to set up a best practice workshop with broadcasters, manufacturers and distributors – Broadcasters who are considering to launch a new or modify an existing accessibility service should contact Nordig Accessibility group. • We should gather information from accessibility groups and broadcasters to understand what their pain points are. • Collaborate with these accessibility groups so they can inform their members how to find/use the existing services. – We propose a question to external accessibility groups: Should Nordig Broadcasters deliver additional accessibility services even if not all IRDs can receive them initially? • Investigate the implications for streaming services on accessibility Excom view? 22
