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.

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.

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 time shifting function.
AV_ON_SD
Unless the power measurement is being made with removable media any other removable
media not being used shall be removed.
5.3.5.2 On-broadcast

5.3.5.5 On-multifunction with a single tuner
Set the VR to record a programme while simultaneously playing back a previously recorded
programme and measure the average power consumed for at least 2 min. Record this as
P . Record the time used to measure the average power. Time shifting is covered in this
MF_ST
measurement as this is the case when the VR is playing back the same program as it is
recording.
NOTE The mechanism for multifunction with a single tuner is the same as for time shift or recording.
5.3.5.6 On-multifunction with a multituner

For SD VRs, only sequence 1 shall be performed. For HD VRs, both sequence 1 and
sequence 2 shall be performed.
5.3.5.7 Standby-active, high
If possible, activate a download mode from the primary service and measure the average
power consumed for at least 2 min. This measurement may require information from the
manufacturer and/or service provider to ensure the transport stream contains a suitable
download and instructions on how to set the VR to receive the download. Record this value as
P . Record the time used to measure the average power.
SAH
NOTE It may not be possible to place the VR into this mode. If this is the case and the value is still required, it
may have to be provided by a manufacturer’s declaration.
5.3.5.8 Standby-active, low
To ensure that the VR is in standby active and not performing any downloading or recording
function, the following procedure should be used.
a) Put the VR into its on mode.
b) If the VR is capable of scheduling a recording then schedule a recording 2 or more hours
in the future.
c) After 5 min in this mode, press the standby or off button on the remote control.
d) Leave the VR for a minimum of 30 min or until higher power mode maintenance activities
within the UUT have been completed.

Measure the average power consumed for at least 2 min. Record this as P . Record the
SAL
time used to measure the average power. Record the time taken to switch to standby active,
low.
5.3.5.9 Standby-passive
To ensure that the VR is in standby passive, the following procedure should be used.
a) Put the VR into its On mode.
b) If the VR is capable of scheduling a recording then schedule a recording 2 or more hours
in the future.
c) After 5 min in this mode, press the standby or off button on the remote control.
d) Leave the VR for a minimum of 30 min or until higher power mode maintenance activities
within the UUT activities have been completed.
Measure the average power consumed for at least 2 min. Record this as P . Record the time
SP
used to measure the average power. Record the time taken to switch to Standby- passive.
NOTE The method for determining standby-active, low and standby-passive are identical as the switching into
either one of these modes is the same. Which mode the VR actually switches to is actually determined by the
platform in which the VR is operating. A VR with a terrestrial tuner will be more likely to be in a passive mode and a
VR with a cable or satellite tuner will be more likely to be in a standby-active, low mode. Both methods are
specified here to be consistent with the definitions in Table 1.
5.3.5.10 Off
Turn the VR off using the power switch, if available, and measure the average power
consumed for at least 2 min. Record this as P . Record the time used to measure the
_OFF
average power.
5.3.5.11 Auto power down
If the UUT includes an auto power down feature, use the following procedure to determine the
auto power down interval and the power consumption after auto power down is completed.
(See Figure 1.)
a) Place the UUT in the On mode with the auto power down function enabled. The auto
power down interval is specified by the manufacturer. The auto power down interval
should be reported.
b) Stop any main functions of the UUT and start a timer to determine the auto power down
interval.
c) Allow the UUT to automatically power down.
d) Monitor the power consumption of the UUT until the power consumption stabilizes.
e) Stop the timer and report the auto power down interval.
f) Measure the average power consumed for a 2 min. Record this as P .
