All conformance testing is performed at the same point. In the c
42、ase where the GSM rejection filter is included (terminal category c), the measurements will be carried out in the front of the GSM rejection filter. 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 afte
43、r Viterbi decoder, TS-PER, MPE FER (FER) (Frame Error Rate before MPE-FEC), MPE-FEC FER (MFER) (Frame Error rate after MPE-FEC). 4.5 Degradation criteria and resynchronization Four different degradation criteria are used. The criteria a and b are used in the non-mobile cases for DVB-T. Criterion c i
44、s for mobile reception in DVB-T and criterion d for DVB-H reception A receiver must be able to acquire a degraded signal and a resynchronization test must be done to ensure the C/N or C/I value is valid. Once the degradation criterion is achieved, all receiver input signals are removed for a period
45、of 5 seconds and then re-applied. The same degradation criterion must be achieved within a further 5 seconds. If that is not the case, then the only degradation criterion that can be used for receiver measurement has to be based upon successful signal acquisition. a) Reference BER, defined as BER =
46、2 104after Viterbi decoding. This corresponds to the quasi error free (QEF) criterion in the DVB-T standard, which states: ”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
47、). The picture failure point is defined as the C/N or C/I value when picture errors become visible. This is preferred if BER measurements are unstable or unavailable. A more objective definition can be made using the ESR5(5 % erroneous second ratio) criterion, which allows one erroneous second withi
48、n the 20 s observation period in the transport stream. Note that the reception quality is poor at picture failure point as one possible error BS EN 62002-2:2008 14 62002-2 IEC:2008(E) in each 20 s interval is too much for fixed TV-reception. The criterion is nevertheless suitable for measurements, a
49、nd a 1 dB to 2 dB carrier power increase will improve the reception quality to QEF level. A useful method to reduce the uncertainty of visual picture failure point is to use the two out of three method. Here 2 out of 3 consecutive 10 s periods must 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 in
