23、word This Group Specification (GS) has been produced by ETSI Industry Specification Group (ISG) on intelligent Compound Content Management (CCM). Modal verbs terminology In the present document “shall“, “shall not“, “should“, “should not“, “may“, “need not“, “will“, “will not“, “can“ and “cannot“ ar
24、e to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of provisions). “must“ and “must not“ are NOT allowed in ETSI deliverables except when used in direct citation. Introduction The present document defines and specifies the additional functional
25、ity required in consumer devices to enable the accurate recreation of both todays television signal, i.e. SDR signal, and the HDR/WCG signal from content created using the relevant production techniques standardized in SMPTE. The requirement not to compromise the quality of the legacy signal using t
26、odays displays but yet to provide the highest quality HDR/WCG signal for a new generation of televisions is onerous and requires analysis to derive an optimal solution. However, given the requirement to achieve backwards compatibility with existing receivers, some additional technology will be requi
27、red in the next generation of HDR/WCG receivers to accurately recreate the HDR/WCG signal. The full HDR system as shown in the figure 1 describes an end-to-end technology suite that enables the creation and distribution of content mastered with a high dynamic range and wide colour gamut. Display man
28、agement may be used to more accurately match the capability of a given television to the HDR/WCG signal source. This creates seamless video experience for the viewer. The display management process may be guided by metadata generated in the HDR encoder. ETSI ETSI GS CCM 001 V1.1.1 (2017-02) 6 Figure
29、 1: Overview of a generic HDR system and the additional HDR Compound Content Management functionality ETSI ETSI GS CCM 001 V1.1.1 (2017-02) 7 1 Scope The present document specifies the additional functionality required in Consumer devices for the reconstruction of an HDR/WCG signal using the “intell
30、igent Compound Content Management“ processing defined. Additionally it defines a method whereby this HDR/WCG signal and its associated metadata is transported over existing commonly used consumer baseband interfaces. This process is one element of an end-to-end HDR video system. The definition of th
31、e overall end-to-end HDR video system is out of scope of the present document. 2 References 2.1 Normative references References are either specific (identified by date of publication and/or edition number or version number) or non-specific.
