HIGH DEFINITION (HD) RECORDING LINK GUIDELINES
FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

international co-operation on all questions concerning standardization in the electrical and electronic fields. To

this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested

in the subject dealt with may participate in this preparatory work. International, governmental and non-

governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

with the International Organization for Standardization (ISO) in accordance with conditions determined by

agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence

between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

the latter.

5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any

equipment declared to be in conformity with an IEC Publication.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

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 comprehensive proposal for this interface including

content protection 62H [2 ]63H [3 ] 0F . The proposal – intended as a guideline – leverages existing

standards IEC 62481-1, and 64H [4] in the field, ensuring interoperability between receivers and

recorders.

interface
IEC 1338/09

NOTE * HDMI (High-Definition Multimedia Interface)1F is a digital 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 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 recognises 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.

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 devices 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 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 defined 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.
IEC 1339/09
Figure 2 – Recording 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 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 requires 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.

6 Guideline terminology and conventions

The HD Recording Link guidelines include references to XML 74H [6 ]75H [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 are used by

HD Recording Link guidelines and the context of their usage.

requirements clause of networking and connectivity2F .

Any of the above selections can be supported via an add-on card, dongle, or equivalent.

7.4 Device discovery and control

The device discovery and control should be performed using UPnP device architecture as

described in 7.3 of IEC 62481-1.

However, the HD Recording Link devices (RCV and REC) must incorporate the following

changes to the device description documents.
a) The RCV and REC must employ the XML element inside the

element of the device description document to indicate adherence to a particular

HDLNK guidelines parts.
b) The value of element is a string as defined below:

7.5 Media management
7.5.1 Purpose

This subclause covers the guidelines for implementing media management, mainly transfer of

content, using the DLNA and UPnP AV architecture.
7.5.2 Support for upload operations

An RCV must support the DLNA upload controller device capability according to IEC 62481-1,

7.4.1.2.4 with the following exception.

• The support for upload functionality as specified in these guidelines is not determined by

the presence of the capability ID (av-upload) in element of the the

device description. Instead, it must be deduced from adherence of a device to the REC

device class specified by defined in 80H 7.4 .

A REC must support the DLNA upload device option according to IEC 62481-1, 7.4.1.7.1 with

the following additional requirements and exceptions.
• DLNA OCM content upload operation must be supported according to IEC 62481-1
7.4.1.7.12.1.
---------------------- Page: 17 ----------------------
SIST EN 62546:2010
– 12 – 62546 © IEC:2009(E)

• The DLNA advertisement of the upload AnyContainer operation and OCM upload content

operation is optional 3F . More specifically:

– it is not required to use the capability ID (av-upload) in element of

the device description to indicate support for the upload AnyContainer operation;

– and it is not required to use @dlna:dlnaManaged attribute to indicate support for OCM

upload content operation.

• The support for upload device option as specified in this guidelines must be deduced from

adherence of a device to the REC device class specified by
defined in 81H 7.4 .
7.5.3 Support for selection of record destination

A REC must support the selection of record destination using the following vendor-specific

UPnP actions of the Content Directory service 82H [5 ] :

a) CDS:X_HDLnkGetRecordDestinations()– returns a list of possible record destinations.

This action is used by RCV to acquire the possible record destinations;
b) CDS:X_HDLnkGetRecordDestinationInfo()– returns properties of a given record

destination. This action is used by the RCV to query the status of a given record

destination (e.g. media type, total capacity, etc.);

c) CDS:X_HDLnkGetRecordContainerID() – returns the CDS container ID associated to a

given record destination. This function is used by the RCV to select a CDS container with

a given record destination. The returned container ID is later used in the execution of the

CreateObject() action of the upload operation.
7.5.4 Actions
7.5.4.1 X_HDLnkGetRecordDestinations()

This action returns a RecordDestination XML document describing the possible record

destinations that a REC device supports, if any. The action is used by the REC to expose the

possible record destinations, see Table 4.
