“…Another concept called the Correct Reception Rate (CRR) has been used in [17,18], but it also is used as a threshold (good/bad reception) and does not enable making any analysis of the perceived video quality as a function of this parameter. Other works have partially analyzed the effect of the signal fading in the video quality [19].…”

This paper presents a model to predict video quality perceived by the broadcast digital television (DTV) viewer. We present how noise on DTV can introduce individual transport stream (TS) packet losses at the receiver. The type of these errors is different than the produced on IP networks. Different scenarios of TS packet loss are analyzed, including uniform and burst distributions. The results show that there is a high variability on the perceived quality for a given percentage of packet loss and type of error. This implies that there is practically no correlation between the type of error or the percentage of packets loss and the perceived degradation. A new metric is introduced, theweighted percentageof slice loss, which takes into account the affected slice type in each lost TS packet. We show that this metric is correlated with the video quality degradation. A novel parametric model for video quality estimation is proposed, designed, and verified based on the results of subjective tests in SD and HD. The results were compared to a standard model used in IP transmission scenarios. The proposed model improves Pearson Correlation and root mean square error between the subjective and the predicted MOS.

This paper presents preliminary results of field measurements carried out for evaluating the operation of the ISDB-TB standard digital TV in the VHF-high band. Measurements were performed in urban, suburban and rural areas in a medium-sized Brazilian city. The analysis includes results of static reception measurements for evaluating the received field strength and the signal to noise ratio thresholds for correct signal decoding. A comparison with theoretical values of field strength is also presented.

“…The performance of integrated receiver/decoders (IRD) for ISDB-T B digital TV standard has been analyzed most frequently in the UHF band in the literature [2] [3] [4], and few works focused the VHF-high band [5] [6]. These two works comprised laboratory tests and field tests respectively.…”

This paper presents an evaluation of the performance of digital TV receivers focusing the parameter signal-to-noise ratio achieved from measurements in laboratory tests and from field tests, and also the multipath data achieved from field tests. The mentioned field tests are a field measurement campaign performed in Brazil aiming the evaluation of ISDB-TB standard digital TV operation in the VHF-high band. From the static measurements of field tests, the parameter signal-to-noise ratio was achieved employing two methodologies, one from direct measurements and the second from noise injection. These results were compared to laboratory tests and to the technical norm of operation in the VHF band. An assessment of the influence of multipath in the digital signal reception and some correlation to the measured signal-to-noise ratio values is also presented.
