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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

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

patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

5 Measuring conditions for video recorders
5.1 Input signal
5.1.1 General

In general terms, input signals shall be of the strength and quality for the type of broadcast

system on which the VR is intended to be used. Where a VR supports multiple broadcast

systems, it shall be tested for each broadcast system in which it operates. Each measured

result shall be described in the report.
5.1.2 RF test signal
5.1.2.1 General

For digital terrestrial, satellite and cable VRs, the test signal shall be a signal representative

of those present in the typical environment in which the VR is intended to be used. The video

and audio components of the transport stream shall be as described in 5.1.2.2 and 5.1.2.3.

For analogue terrestrial, satellite and cable VRs, the signal should be typical of the type of

signal the VR is designed to receive.
5.1.2.2 Video test signal

The VR shall be tested using an appropriate input signal. This signal should be at the highest

resolution that the VR is capable of decoding using the most processing intensive advanced

decoding standard of the intended broadcast system(s) that the VR will be used on. A

description of the signal used for the test shall be included in the test report. This description

shall include at a minimum, resolution, frame rate and bit rate.

If the VR under test is an HD decoder, additional testing may also be conducted with an SD

input signal.

Where the VR is operating in a download or recording mode, the input signal should contain

content that simulates material that would typically be downloaded or recorded.

Where a VR has a conditional access system, it should be tested whilst decoding encrypted

content.

Where a VR can record other services than the one being watched, the test signal should

contain sufficient services to enable this feature to be tested.
5.1.2.3 Audio test signal

The VR shall be tested using an appropriate input signal. The audio test signal should have

the maximum data rate (bit/s).

The audio format used during the power measurement shall be described in the report.

5.1.3 Broadband input signal

An input signal that provides the equivalent multiplexed transport stream as an appropriate

internet protocol (IP) broadband signal conforming to 5.1.2.2 and 5.1.2.3.
---------------------- Page: 11 ----------------------
– 10 – IEC 62087-4:2015 © IEC 2015
5.2 Input terminals
5.2.1 Analogue terrestrial input terminal

If the VR is being tested with an analogue terrestrial RF input signal, the signals used shall

conform to IEC 60107-1:1997, 3.3, and shall have the input signal level set at –39 dB(mW)

when terminated with a 75 Ω resistor or at a level to provide a perceptually noise free or error

free picture.
NOTE 39 dB(mW) corresponds to 70 dB(µV).
5.2.2 Cable television input terminal

If the VR is being tested with a cable television RF input signal, the signals used shall

conform to the cable television specifications for the region, and shall have the input signal

level set at –49 dB(mW) with a termination of 75 Ω resistor or at a level to provide better than

the picture failure point (PF) as defined in IEC 62216 for digital signals or a perceptually noise

free picture or error free for analogue signals.
NOTE 49 dB(mW) corresponds to 60 dB(µV).
5.2.3 Digital terrestrial input terminal

If the VR is being tested with a digital terrestrial RF input signal, the signals used shall

conform to the broadcast specifications for the region, and shall have the input signal level set

at –49 dB(mW) with a termination of 75 Ω resistor or at a level to provide better than the

picture failure point (PF) as defined in IEC 62216 or a perceptually noise free picture.

5.2.4 Satellite input terminal

If the television set is being tested with a satellite input signal, the input signal level shall be

set at −49 dB(mW) with a termination of 75 Ω resistor or at a level to provide better than the

picture failure point (PF) as defined in IEC 62216 for digital signals or a perceptually noise

free picture or error free for analogue signals.
5.3 Measurement procedure
5.3.1 General measuring conditions

The general measuring conditions including the type of power meters to be used is as per

IEC 62087-1:2015 except where conditions are otherwise specified in this subclause.

5.3.2 Stabilization

The measurements shall be performed after the VR has achieved a stable condition with

respect to power consumption. Refer also to IEC 62087-1:2015.

NOTE There are several ways to consider a VR stable. For example, a VR can be considered stable between

15 min and 30 min after entering into each operation mode. In this case, the time used to stabilize the VR shall be

recorded in the test report. A VR can be also considered stable when any of the results of the same test repeated

are within 2 %.
5.3.3 Environmental conditions
The ambient temperature shall be 23 ºC ± 5 ºC. Refer also to IEC 62087-1:2015.
5.3.4 Setup

The VR shall be set up in a manner to simulate a normal operating environment. In this

condition, the measurement shall be made without optional peripheral devices attached to the

device. The input signals to the VRs may be either live signals or generated test streams that

simulate live signals that the VR is designed to receive and decode.
---------------------- Page: 12 ----------------------
IEC 62087-4:2015 © IEC 2015 – 11 –

Where a VR can power an LNB of an antenna amplifier this power shall not be included in the

measurement. Where possible this power supply should be disabled. Where it cannot be

disabled isolation connectors should be used to isolate the power supply.

If required the LNB or antenna amplifier should be powered from an external power source to

the VR.

If possible, any function which may work in background of any On mode function should be

disabled (turned off). If possible, any function which may cause the interruption of any On

mode function should also be disabled (turned off). If they cannot be disabled the

measurement should be scheduled so as to avoid working such background functions during

the measurement.

NOTE Examples of background and/or interrupt functions for any On mode function are:

– background software download/install;
– timer recording;
– automatic deletion of an old TV programme which was recorded.
5.3.5 Power measurements
5.3.5.1 General

The VR under test shall be measured in each applicable mode as specified below. In the case

of HD VRs, testing shall be with an HD input signal. Testing with an SD input signal may also

be conducted. Where the SD test is conducted on an HD VR, the result shall be recorded as

P . If possible disable the
