Figure 1 – Reference model
The receiver performance figures are all specified at the reference point, which is the input of
the receiver. All conformance testing is performed at the same point.
In the case where the GSM rejection filter is included (terminal category c), the measurements
can be carried out in the front of the GSM rejection filter and the allowed noise figure
degradation is at most 1 dB. This degradation is to be included in the receiver minimum input
signal level values. For all other measurements, the reference point can be moved to the front
of the GSM rejection filter and all other requirements remain the same.
In the case of a DVB-H receiver, the manufacturer shall provide the specified test mode in
which the following parameters can be monitored.
• TS-BER after Viterbi decoder
• TS-PER
• MPE-FEC FER
4.5 Degradation criteria
Four different degradation criteria are used. The criteria a and b are used in the non-mobile
cases. Criterion c is for mobile reception and criterion d for DVB-H reception.
–4
a) Reference BER, defined as BER = 2 × 10 after Viterbi decoding
This criterion corresponds to the DVB-T standard defined QEF criterion, causing ”less
than one uncorrected error event per hour”. In the stationary reception cases, QEF is
equivalent to the reference BER after Viterbi decoding.
b) Picture failure point (PFP)
The PFP is defined as the C/N or C/I value where visible picture errors start to appear on
the screen. This is more convenient for some of the measurements than the normal
reference BER criterion, which might be unreachable. A more objective definition can be
made using the ESR (erroneous second ratio 5 %) criterion, which allows one erroneous
second within the 20 s observation period in the transport stream. Note that the reception
quality is poor at PFP as one possible error in each 20 s interval is too much for fixed TV
reception. The criterion is nevertheless suitable for measurements, and a 1-2 dB carrier
power increase will improve the reception quality to QEF level. A useful method to reduce
the uncertainty of visual PFP is to use the two out of three method. Here 2 out of 3
consecutive 10 s periods shall be good (no artefacts), i.e. 1 out of 3 can contain artefacts.
More complex M out of N periods can lead to more accurate results but will increase the
measurement time. Table 2 shows the correlation between the PFP and the reference BER

62002-2  IEC:2005(E) – 13 –
error criterion for various measurements. When the PFP is used in the measurement, the
measured value can be converted to corresponding reference BER value by using Table 2.

c) Subjective failure point in mobile reception (SFP)
The reference BER, meaning perfect “quality of transmission”, is unfortunately not suitable
in the mobile environment due to the fast channel variations. In mobile cases, the
reference BER criterion may give unstable values, which could result in an underestimation
of DVB-T mobile capabilities. Within the motivate project [5] , a subjective quality has
been defined, referred to as the SFP. The SFP corresponds to: “on average, one visible
error in the video, during an observation period of 20 s”. This corresponds to the ESR
(erroneous second ratio 5 %) criterion, which allows one erroneous second within the 20 s
observation period. Thus, the ESR method can be used to measure the SFP. The SFP
–4
corresponds also fairly well to a PER = 10 after RS decoder at the demodulator TS
output. The observation period for the PER measurement should be at least 800 k TS
packets, corresponding roughly to 2 min with 16QAM CR = 1/2 GI = 1/4 mode.
d) DVB-H error criterion
In DVB-H a suitable degradation criterion is the MPE-FEC frame error rate (MFER),
referring to the error rate of the time-sliced burst protected with the MPE-FEC. As an
erroneous frame will destroy the service reception for the whole interval between the
bursts, it is appropriate to fix the degradation point to the frequency of lost frames.
Obviously, the used burst and IP parameters will affect the final service quality obtained
with certain fixed MFER, but experience has shown that the behaviour is very steep and a
very small change in C/N will result in a large change in MFER.
MFER is the ratio of the number of erroneous frames (i.e. not recoverable) and total
number of received frames. To provide sufficient accuracy, at least 100 frames shall be
analysed.
Number of erroneous frames × 100
MFER[]% =
Total number of frames
It has been agreed that 5 % MFER is used to mark the degradation point of the DVB-H
service. Note that the service reception quality at the 5 % MFER degradation point may not
meet the QoS requirement in all cases. The criterion is nevertheless suitable for
measurements, and a small 0,5 to 1dB carrier power increase will improve the reception
quality to less than 1 % MFER.
It is also possible to estimate the MFER with good accuracy without performing the actual
MPE-FEC calculation by just observing row by row the number of erroneous bytes and
comparing this with the error correction capability of the RS code used and marking the
row erroneous or non-erroneous. If all rows are non-erroneous, the frame is non-
erroneous. With this method, it is possible to decode all services (i.e. the whole transport
stream) in parallel and shorten the observation time for the 100 frames needed.

Figures in square brackets refer to the Bibliography.

– 14 – 62002-2  IEC:2005(E)
In DVB-H receivers with no MPE-FEC, the frame error rate criterion can be used in a
slightly different way. A frame is marked as erroneous if any TS packet within the frame is
erroneous. This criterion is called FER and degradation point is set to 5 % value. Note that
5 % FER may lead to better actual QoS than 5 % MFER as in FER it is possible that only a
few TS packets within the frame are erroneous, but in MFER a non-recoverable frame is
probably highly corrupted. The actual performance figures with FER 5 % are very similar
what would be achieved using ESR criterion to the transport stream directly.
4.6 Definition of C/N
C/N is measured from the test signals by measuring the noise level in dB(mW) present at the
received channel bandwidth (5,71 MHz, 6,67 MHz or 7,61 MHz) and comparing the DVB-T/H
signal level (dB(mW)) to the measured noise level.
Example: Measured noise level at 7,61 MHz channel bandwidth is –70 dB(mW). Measured
DVB-T/H signal level is –50 dB(mW). Resulting C/N is 20 dB.
4.7 Definition of measurement signals
4.7.1 Wanted DVB-T/H signal and interfering DVB-T signal definition
The DVB-T signal is according to ETSI EN 300 744.
In the case of DVB-H, the signal used in measurements has a burst size of 2 Mbits. The DVB-
H burst bit rate is always 4 Mbit/s independent of modulation. MPE-FEC parameters are 1 024
rows, CR 3/4. These parameters will result approximately in a duration of 0,5 s time-slicing
bursts. The repetition rate of bursts can vary, and higher rates than typically used in real
networks can be used to speed up the measurement. As an example, a repetition rate with a
50 % on/off period can be used.
4.7.2 Interfering signal definitions
Figure 2 shows the PAL B/G/I1 interfering signals. Modulating signals are: 75 % colour bars
for the vision carrier, 1 kHz FM sound with ±50 kHz deviation and any modulation for NICAM.
The level of the FM sound carrier relative to the vision carrier is –13 dB. The level of the
NICAM signal relative to the vision carrier is –20 dB. Note that the filter roll-off factor for PAL
B/G NICAM is 40 % and PAL I1 NICAM is 100 %.

5.2.3 C/N performance in mobile channels
The performance in IEC 62002-1 is specified at 1/32 guard interval, but the conformance
measurement is carried out with the more practical guard interval of 1/4. The performance
expected at the 1/4 guard interval is 85 % of that with 1/32 guard interval and the calculated
figures are shown in Table 5.

5.3 Test purpose
The purpose of this test is to verify the C/N performance of the receiver in different channel
conditions specified in Table 3, 4 and 5.
The purpose of the C/N test performed in Gaussian channel conditions is to verify the
operation of the terminal under ideal channel conditions. The portable channel conditions are
used to test the performance of the terminal under conditions where the channel is stationary
multipath channel without direct path. The mobile channel model is used to verify the
operation of the terminal while moving in a car.
5.4 Method of test
5.4.1 Initial conditions
Frequencies to be tested: the measurements are performed at channel 45 (666 MHz).
Reception modes to be tested:
In Gaussian channels: all modes specified in IEC 62002-1, 10.7.1. The test can be carried out
with 2 k or 4 k or 8 k modes or any combination of these.

– 18 – 62002-2  IEC:2005(E)
In portable channels: all modes specified in IEC 62002-1, 10.7.2 are tested. The test can be
carried out with 2 k or 4 k or 8 k modes or any combination of these.
In mobile channels: the modes QPSK 1/2, 16QAM 1/2 and 16QAM 2/3, all using guard interval
1/4. The highest available FFT-size is selected.
For DVB-H receivers with MPE-FEC when measuring with mobile channels, the failure point
criterion is DVB-H error criterion (failure criterion d) using DVB-H performance target figure.
DVB-H receivers without MPE-FEC are measured using FER criterion and the performance
target figure of DVB-T. Other measurements are done with the same criteria as DVB-T.
5.4.2 Measurement setup
The measurement setup is shown in Figure 4.
DVB-T/H Channel

source simulator
Figure 4 – Example of a possible measurement setup in C/N performance tests
a) Connect the DVB-T/H signal source to the channel simulator and noise source. Feed the
signal into the terminal reference point shown in Figure 1. If the C/N of the DVB-T/H signal
source can be set, it can be used in measurements instead of noise source.
b) Set the correct channel model to the channel simulator.
c) Set correct modulation and signal parameters to the DVB-T/H signal source.
d) Set the DVB-T/H signal source to channel 45 (666 MHz).
e) Set the DVB-T/H signal source power level to –50 dB(mW), when measured from the
terminal reference point.
f) Tune the terminal to channel 45 (666 MHz).
g) Perform the measurement as described in 5.4.3.
