23、EN 62546:2009 6 62546 IEC:2009(E) INTRODUCTION With the global introduction of High definition (HD) TV services, receivers, and consumer recording equipment, the need has arisen for a universal recording interface to connect receivers and recorders. This International Standard presents a comprehensi
24、ve proposal for this interface including content protection 62H 263H 3 0F1. The proposal intended as a guideline leverages existing standards IEC 62481-1, and 64H 4 in the field, ensuring interoperability between receivers and recorders. NOTE * HDMI (High-Definition Multimedia Interface)1F2is a digi
25、tal interface for the connection between source device and monitor provided by HDMI Licensing, LLC. Figure 1 High definition reception and recording The starting point for the proposal is an in-home configuration depicted in 65HFigure 1. The assumption is that both the receiver (e.g. STB) as well as
26、 the recorder (e.g. BD-recorder) are connected to the display via an HDMI interface 66H 4. The proposed recording interface connects the recorder to the receiver and carries compressed signals only. Obviously, the receiver functionality can be integrated into the display. The proposed interface reco
27、gnises the fact that a large amount of content will be made available in the form of a Pay-TV and thus be protected via a Conditional Access (CA) system. The required CA functionality is assumed to be contained in the receiver. _ 1Figures in square brackets refer to the Bibliography. 2HDMI is the tr

In addition, it should be noted that this guideline implements the scheduled recording use case without reservation of the storage on the recorder side. Other use cas
39、es described in Annex A may be covered by the future publications. BS EN 62546:200962546 IEC:2009(E) 9 5 System definition 5.1 Device model HD Recording Link guidelines uses the device model described in DLNA (see Clause 5 in IEC 62481-1). This subclause maps the receiver and the recorder (target de
40、vices for the guidelines) to DLNA device model. This guideline provides the requirements for the following devices: a) RCV receiver is a device that consists of one or more broadcasting tuner(s), an IP-based home network interface and may have storage for recording content. The storage functionality
41、 of the receiver is not covered by the guidelines; b) REC recorder is a device that consists of a storage for recording content (removable or non-removable or both) and an IP-based home network interface. 5.2 System usage The system usage describes the device interaction model between devices define
42、d in this document in order to realise the use cases listed in Clause 71H 4. The usage covers the use cases addressed in Clause 72H 4 of this document. The recording system usage has an upload controller device capability in the RCV to instruct the REC to accept the content for recording. Figure 2 R
43、ecording system usage interaction model 73HFigure 2 illustrates the device interaction model. The following steps are performed in the system usage: invoke UPnP action to select the destination media (HDD, BD, etc.); invoke UPnP action to create a CDS entry for the content to be recorded; transport
44、the content to the recorder. It should be noted that the upload controller device capability is incorporated as part of a valid DLNA device. In preparation for the next steps of the guidelines it has been decided to host the upload controller device capability in a DMS. Therefore, the receiver requi
45、res adherence to the DMS device class although the functionality of the DMS is not required to implement the use cases realised by the current guidelines. IEC 1339/09 BS EN 62546:2009 10 62546 IEC:2009(E) 6 Guideline terminology and conventions The HD Recording Link guidelines include references to
46、XML 74H 675H 7 elements and attributes without the definition of formal HDLNK XML schema. This allows the HD Recording Link guidelines to define new XML elements and attributes in the future, without having to define a new namespace or schema definition. 76HTable 1 lists the namespace values that ar
