“…In this way, the approach to implement a third lambda configuration is to broadcast all traditional television channels using the additional down-link at 1550 nm, freeing the corresponding bandwidth in the 1310 nm and 1490 nm links. Because the RF signal sent in the third lambda allows only very simple (i.e., spectrum inversion) or even no encryption, it is not suitable to transmit premium contents subject to subscription, which are still sent by IP using the conventional up-and down-links at 1310 nm and 1490 nm [15]. Figure 2 shows a detailed scheme of the structure of a GPON to implement triple-play services using the third lambda.…”

This work presents a reconfigurable RF converter for DVB-T television applications using triple-play over GPON. The system takes the DVB-T input, a wavelength division multiplexing (WDM) signal with spectral inversion in the range from 47 M Hz –1000 M Hz , up-converts its frequency to the band-pass of a highly selective surface-acoustic wave (SAW) filter centered at 1 . 3 G Hz , and then down-converts it so that it is compatible with the antenna input of conventional television sets. The designed RF converter incorporates two pairs of frequency synthesizer and mixer, based, respectively, on an integer-N phase-locked loop (PLL) with two LC-tank VCOs with 128 coarse tuning bands in the range from 1.35 G Hz –2.7 G Hz , and a double-balanced Gilbert cell, modified for better impedance matching and improved linearity. It is fed with regulated supplies compensated in temperature and programmed by an I 2 C interface operating on five 16-bit registers. This work presents the experimental characterization of the whole system plus selected cells for stand-alone testing, which have been fabricated in a 0 . 18 m CMOS process.

“…Starting from the fact that in IPTV, the main influencing factor of QoE for users is TV channels availability, Wolfinger et al introduced a new model to measure the QoE in [69]. It is an analytical model that predicts the blocking probability of TV channels for channel-switching-induced and handover-induced blocking events in IPTV services in VANETs.…”

Survey on QoE/QoS Correlation Models for Video Streaming over Vehicular Ad-hoc Networks

Vehicular Ad-hoc Networks (VANETs) are a new emerging technology which has attracted enormous interest over the last few years. It enables vehicles to communicate with each other and with roadside infrastructures for many applications. One of the promising applications is multimedia services for traffic safety or infotainment. The video service requires a good quality to satisfy the end-user known as the Quality of Experience (QoE). Several models have been suggested in the literature to measure or predict this metric. In this paper, we present an overview of interesting researches, which propose QoE models for video streaming over VANETs. The limits and deficiencies of these models are identified, which shed light on the challenges and real problems to overcome in the future.

“…In IPTV, QoE is mainly determined by the availability of TV channels for the users. In [5], the author presents an efficient and rather generally applicable analytical model that allows one to predict the blocking probability of TV channels, both for channel-switching-induced, as well as for handover-induced blocking events. We present the successful validation of the model by means of simulation, and we introduce a new measure for QoE.…”

Communications between vehicles are seen as a solution for road transport problems, such as accidents, inefficiencies, traffic congestions, fuel consumption, and exhaust emissions. However, before implementing such a solution, some preliminary analysis is needed. First, the most convenient communications technologies should be selected for each application and specific communications architecture should be deployed to support such services. Standardization is essential for successful deployment.[...]
