    DVB指导委员会批准UHD HDR标准

    The DVB Steering Board approved a new version of the TS 101 154 specification, adding the technical elements for High Dynamic Range (HDR), Higher Frame Rates (HFR) and Next Generation Audio (NGA). The new specification is a major milestone for the industry, guaranteeing interoperability and enabling broadcasters and CE manufacturers to provide UHD-1 Phase 2 products and services. This could mean that the first DVB services offering HDR, HFR and NGA would be available from next year.

    DVB指导委员会批准了TS 101 154标准的一个新版本,添加了三个技术元素在里面,包括HDR(High Dynamic Range), HFR(Higher Frame Rates)和NGA(Next Generation Audio)。这个新标准,对于那些提供UHD-1 Phase 2产品和服务的工业、安防、广播、消费电子产品和服务者来说,是一个里程碑,它意味着明年将开启包含HDR、HFR和NGA技术的DVB服务。

    The specification covers various elements for the improvement of video and audio quality for broadcast TV services including High Dynamic Range (HDR) which significantly increases the contrast ratio and results in pictures with more 'sparkle'. The DVB HDR solution supports Hybrid Log Gamma (HLG) and PQ (Perceptual Quantizer). Furthermore, the new specification defines Higher Frame Rates (HFR), going beyond the current 50/60 Hz. HFR offers sharper images of moving objects. When it comes to audio, DVB has added the latest Next Generation Audio (NGA) schemes supporting object- or scene-based audio. These new features can be combined with HD and UHD resolutions.

    这个标准覆盖多个元素,去提高广播电视音视频的质量。
    DVB HDR极大提升了画面的对比度,带来更多的亮点,它支持HLG(Hybrid Log Gamma)和PQ(Perceptual Quantizer)。
    HFR提供超过当前的50/60Hz更高的帧率,在运动物体展现更鲜明的画面。
    NGA引入支持基于音频的对象和景观全新的展现方式。
    这些都将被应用在高清和超高清画面的展示方式中。

    The specification has been published as BlueBook A157 and will be passed to ETSI for formal publication as TS 101 154 v2.3.1.

    这一标准被正式发布为ETSI TS 101 154 v2.3.1

    Commenting on the new specification, DVB Chairman, Peter MacAvock said “Today’s approval of the specification is the result of enormous effort from the contributors, and further evidence of DVB’s leadership in the broadcast industry. DVB views the Phase 2 specification as a key enabler for exciting products and services.”

    The specification was a massive team effort with over 30 companies and other interested parties participating through the DVB Commercial Module, the Technical Module and the Steering Board. It is estimated that some 36 online meetings and 14 physical meetings took place over the 3 years. This commitment by DVB Members bears testament to how standards’ bodies play an important role and emphasizes the importance of getting consensus and wide approval for new standards.

    Ken McCann, Chair of TM-AVC, said “This latest revision of the TS 101 154 adds exciting new features to ensure that DVB continues to meet the industry’s demands for ever-improving video and audio quality. It’s a great team effort that marks the culmination of the most intense year of work in TM-AVC’s 20 year history.”

    Congratulations to all those who contributed to the huge team effort required to get this important document agreed on time - and particularly to Virginie Drugeon, Vice-Chair of TM-AVC and chief editor of the specification, for her excellent editorial leadership.
