4 Use cases
Annex A shows the following use cases derived from the interconnection depicted in 6 7 H Figure 1 .
a) Impulse recording (What You See Is What You Record – WYSIWYR)
b) Scheduled recording
c) Pause TV
d) Archiving
This standard addresses the following two use cases described in 6 8 H A.4.3 and Clause 6 9 H A.6, but not others described in 7 0 H Annex A.
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 cases described in Annex A may be covered by the future publications.
5 system definition5.1 Device model
HD Recording Link guidelines uses the device model described in DLNA(see Clause 5 inIEC 62481-1).This subclause maps the receiver and the recorder (target devices for theguidelines) 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 lP-
based home network interface and may have storage for recording content. The storagefunctionality 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 lP-based home network interface.
5.2system usage
The system usage describes the device interaction model between devices defined in thisdocument in order to realise the use cases listed in Clause 4.
The usage covers the use cases addressed in Clause 4 of this document.The recordingsystem usage has an upload controller device capability in the RCV to instruct the REC toaccept the content for recording.
Figure 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 the content to the recorder.
