N
16、OTE: The EBU/ETSI JTC Broadcast was established in 1990 to co-ordinate the drafting of standards in the specific field of broadcasting and related fields. Since 1995 the JTC Broadcast became a tripartite body by including in the Memorandum of Understanding also CENELEC, which is responsible for the
17、standardization of radio and television receivers. The EBU is a professional association of broadcasting organizations whose work includes the co-ordination of its members activities in the technical, legal, programme-making and programme-exchange domains. The EBU has active members in about 60 coun
18、tries in the European broadcasting area; its headquarters is in Geneva.

19、rk operators, software developers, regulatory bodies, content owners and others committed to designing global standards for the delivery of digital television and data services. DVB fosters market driven solutions that meet the needs and economic circumstances of broadcast industry stakeholders and
20、consumers. DVB standards cover all aspects of digital television from transmission through interfacing, conditional access and interactivity for digital video, audio and data. The consortium came together in 1993 to provide global standardisation, interoperability and future proof specifications. Th

37、ing different CPCM Instances in the same CPCM Device A CPCM Device may implement one or more CPCM Instances. The decision to have one or more CPCM Instances in one CPCM device is guided by the following considerations: A CPCM Instance may implement several CPCM Functions. Each CPCM Instance has its
38、own certificate and as such may be individually identified or revoked. It is therefore possible to revoke a given CPCM Instance in a CPCM Device without affecting the behaviour of other CPCM Instances present in the same CPCM Device. As each CPCM Instance may be revoked separately, implementations n
39、eed to be such that the compromising of one CPCM Instance does not affect other CPCM Instances in the same CPCM Device. Consequently, a CPCM Instance will not be able to access Secure Data of other CPCM Instances in the same CPCM Device. Similarly, implementations of two CPCM Instances in the same C
40、PCM device will be distinct so that the compromising of one implementation does not affect the behaviour of other implementations. Thus, the implementation cost is likely to grow with the amount of different CPCM Instances. Unless otherwise authorised by the applicable C in this case, the smart card
41、 will work only with devices implementing that proprietary extension, most likely with devices from the same manufacturer. Using a standardised CPCM extension: in this case the interface will probably be secured using CPCM SAC. However, additional messages may need to be defined for the extension (e
42、g. to transmit the Content Descrambling Key). The smart card is likely to work with any device from any manufacturer, as long as it implements the CPCM extension. 4.2 Selection of suitable CPCM Functions for a device This clause gives examples for CPCM implementers in order to help them determine w
43、hich CPCM Functions need to be implemented in their products to achieve their design requirements. 4.2.1 Portable Media Player This example of a Portable Media Player, PMP, is a device that is able to receive CPCM content from a CPCM sourcing device to record it locally and to play back the content
44、for consumption. This playback can occur on the integrated screen or on a remote display using a digital link, protected with a dedicated CPS. Figure 3: Portable Media Player Example For this example, the following CPCM Functions are to be implemented: Storage Entity, for the PMP local storage Consu
45、mption Point, for the integrated screen Export Point to the CPS used on the digital link There is also a possibility that the PMP device can provision content for a target device be it CPCM or not; the PMP device supports a resident or downloadable application that can process the content, e.g. down
46、resolution or transcode. In such case, a Processing Entity Function is needed. ETSI ETSI TR 102 825-12 V1.1.1 (2011-03)184.2.2 Pay-TV Personal Video Recorder This example of a PVR is a device that is able to receive content from a Pay-TV operator, to record it locally and to play back the content u
47、sing an analogue output. The analogue output has an analogue protection system. Figure 4: Pay-TV Personal Video Recorder Example For this example, the following CPCM Functions are to be implemented: Acquisition Point, to import content into CPCM from the Pay-TV CAS Storage Entity, for the local stor
48、age Consumption Point, for the analogue output function Export Point Function is not needed since the analogue output is protected. 4.2.3 Pay-TV Set-Top-Box In this example, a Set Top Box is a device that is able to receive content from a Pay-TV operator and to play it back using a digital output th
49、at includes a protection system. Figure 5: Set-Top-Box Example ETSI ETSI TR 102 825-12 V1.1.1 (2011-03)19For this example, the following CPCM Functions are to be implemented: Acquisition Point, to import content into CPCM from the Pay-TV CAS Consumption Point, for the digital output function Export Point Function is not needed since the digital output is protected. 4.2.4 Home Gateway In this example, the Home Gateway is capable of receiving non-CPCM content, storing it internally
