17、elevision and data services. DVB fosters market driven solutions that meet the needs and economic circumstances of broadcast industry stakeholders and consumers. DVB standards cover all aspects of digital television from transmission through interfacing, conditional access and interactivity for digi

18、tal video, audio and data. The consortium came together in 1993 to provide global standardisation, interoperability and future proof specifications. The present document is part 9 of a multi-part deliverable. Full details of the entire series can be found in part 1 8. Introduction CPCM is a system f

19、or Content Protection and Copy Management of commercial digital content delivered to consumer products. CPCM manages content usage from acquisition into the CPCM system until final consumption, or export from the CPCM system, in accordance with the particular usage rules of that content. Possible so

20、urces for commercial digital content include broadcast (e.g. cable, satellite, and terrestrial), Internet-based services, packaged media, and mobile services, among others. CPCM is intended for use in protecting all types of content - audio, video and associated applications and data. CPCM specifica

21、tions facilitate interoperability of such content after acquisition into CPCM by networked consumer devices for both home networking and remote access. This first phase of the specification addresses CPCM for digital Content encoded and transported by linear transport systems in accordance with TS 1

22、01 154 1. A later second phase will address CPCM for Content encoded and transported by systems that are based upon Internet Protocols in accordance with TS 102 005 i.1. ETSI ETSI TS 102 825-9 V1.2.1 (2011-02)61 Scope The present document contains normative specifications for the Adaptation Layers b

23、etween Digital Video Broadcasting (DVB) Content Protection and Copy Management (CPCM) system and underlying technologies. CPCM Phase 1 includes the adaptation layer for content carried inside an MPEG-2 transport stream (TS) (see TS 101 154 1) specified in clause 4.1. 2 References References are eith

39、ransport Stream 4.1.1 General This clause specifies the adaptation layer of the CPCM System for handling of CPCM Content (C.0) in the form of the MPEG-2 Transport Stream, defined in TS 101 154 1. The CPCM System does not specify the content formats carried within the MPEG-2 Transport Stream. These a

40、re defined, if at all, in the adaptation layers of the respective home network ecosystems (see TS 102 905 3) and application-specific physical interfaces. Otherwise the contents of the TS may be anything that is compliant with TS 101 154 1. The following aspects are specified in the subsequent claus

41、es: CPCM Content scrambling for MPEG-2 TS. Embedded carriage of the CPCM protocol message containing the CPCM Content Licence (CL) in MPEG-2 TS. Embedded carriage of the CPCM Auxiliary Data in MPEG-2 TS. Content scrambling key change and synchronisation for MPEG-2 TS. Carriage of the CPCM Revocation

42、 List in MPEG-2 TS. 4.1.2 CPCM Content Scrambling for MPEG-2 TS The CPCM Security Toolbox specification (TS 102 825-5 10) defines the application of the CPCM Scrambling Tool to an MPEG-2 Transport Stream that is to be scrambled within the CPCM System. The CPCM Acquisition Point shall ensure that the

43、 value of scrambling_control_bits in the MPEG2-TS header of the CPCM Content Item is consistent with the setting of the odd_even_key_indicator bit in the CPCM_descrambler_information field within the CPCM Content Licence, as specified in TS 102 825-4 9. The settings are shown in table 1. This might

44、require a change in the MPEG2-TS header. Table 1: Application of TS header scrambling control bits Bit values Description 00 No scrambling of TS packet payload (MPEG-2 compliant) 01 Reserved for future DVB use 10 TS packet scrambled with Even Key 11 TS packet scrambled with Odd Key If the correspond

45、ing Input Content applies different settings of the MPEG-2 TS header scrambling_control_bits, for example if crypto-periods are applied then these bits will be continually changing, the Acquisition Point shall change these settings in the TS header in order to comply with the CPCM settings as descri

46、bed. 4.1.3 Embedded carriage of the CPCM Content Licence in MPEG-2 TS The CPCM Content Licence (CL) shall be carried (embedded) within the (partial) TS that constitutes a CPCM Content Item, by the following means: For each service which is part of a CPCM Content Item, the corresponding PMT shall ind

47、icate the location of the CPCM Content Licence by means of a CP_descriptor indicating a CP_system_id allocated in TS 101 162 i.2 to DVB CPCM for CL carriage. The CP_descriptor is specified in EN 300 468 2. The CP_descriptor shall reference a PID where any protocol message that contains the CL will b

48、e found. ETSI ETSI TS 102 825-9 V1.2.1 (2011-02)9When the Content Licence is SAC protected, the entire CPCM message, except for the CPCM Auxiliary Data, shall be carried at that location. When the Content Licence is only AD protected, only the Content Licence shall be carried at that location. 4.1.4

49、 Embedded carriage of the CPCM Auxiliary Data in MPEG-2 TS The CPCM Auxiliary Data, if present for the associated Content Item, shall be carried (embedded) within the (partial) TS that constitutes a CPCM Content Item, by the following means: For each service which is part of a CPCM Content Item, the corresponding PMT shall indicate the location of the CPCM Auxiliary Data by means of a CP_descriptor indicating a CP_system_id allocated in TS 101 162 i.2 to DVB CPCM for Auxiliary D
