“…PSNR compares the maximum possible signal energy, i.e, the maximum value of the luminance component of the frame, to the noise energy, that is the mean square error (MSE) computed pixel by pixel between the source frame and the received frame [5]. The PSNR in dB can express as : (6) x denote as source frame and y as received frame. MSE(x,y) denotes the mean square error between x and y. Vpeak = 2 k -1, where k is the number of bits per pixel.…”

This paper presents about the transmission of Digital Video Broadcasting system with streaming video resolution 640x480 on different IQ rate and modulation. In the video transmission, distortion often occurs, so the received video has bad quality. Key frames selection algorithm is flexibel on a change of video, but on these methods, the temporal information of a video sequence is omitted. To minimize distortion between the original video and received video, we aimed at adding methodology using sequential distortion minimization algorithm. Its aim was to create a new video, better than original video without significant loss of content between the original video and received video, fixed sequentially. The reliability of video transmission was observed based on a constellation diagram, with the best result on IQ rate 2 Mhz and modulation 8 QAM. The best video transmission was also investigated using SEDIM (Sequential Distortion Minimization Method) and without SEDIM. The experimental result showed that the PSNR (Peak Signal to Noise Ratio) average of video transmission using SEDIM was an increase from 19,855 dB to 48,386 dB and SSIM (Structural Similarity) average increase 10,49%. The experimental results and comparison of proposed method obtained a good performance. USRP board was used as RF front-end on 2,2 GHz.

“…In this case, the FFT size is the one which provides a trade-off between capacity and performance in mobility. The selected guard interval and pilot pattern are also a trade-off between overhead and performance in indoor scenarios [17]. On the whole, the signal was defined so as to maintain a similar capacity (1.1 Mbps) in all the configuration modes dedicated to mobility services in the DVB-T2 Lite component.…”

This paper presents the field trials carried out in Bilbao (Spain) for testing and analyzing the performance of the DVB-T2 indoor (fixed and pedestrian) reception. Test services with different DVB-T2 and T2-Lite configuration modes have been broadcasted and indoor measurements have been carried out. As a result, signal to noise ratio threshold values for DVB-T2 indoor reception have been obtained. These values update those provided by previous studies and are also valid for planning tools to be used by broadcasters in the development of DVB-T2 networks.

“…As with DVB-T, the performance of DVB-T2 in mobile scenarios has brought attention in the literature [39]. In particular, the robustness of the signalling data in mobile channels has been studied in several works [40,41].…”

The combined use of diversity in the time, frequency, and space domains constitutes a powerful instrument to improve the reception of mobile broadcasting services. The improvement brought by the utilization of diversity techniques can be translated into an extended coverage of mobile services, or into a reduction of the network infrastructure. This dissertation addresses the use of diversity for the provision of mobile services in the European family of terrestrial broadcasting systems standardized by the DVB (Digital Video Broadcasting) consortium. This includes the first and second generation systems DVB-T (Terrestrial), DVB-H (Handheld) and DVB-T2 (Terrestrial 2nd Generation), as well as the next generation system DVB-NGH. Nevertheless, the work carried out in this dissertation is of generic nature and can be applied to future evolutions of standards such as the Japanese ISDB-T or the American ATSC. Our investigations employ an information-theoretic approach to obtain the performance limits of diversity techniques, as well as physical layer simulations to evaluate the performance in real systems.The investigations carried out in the context of DVB-T, DVB-H, and DVB-T2 are aimed at the simultaneous delivery of fixed and mobile services in terrestrial broadcasting networks. The convergence of the fixed and mobile paradigms can facilitate the introduction of mobile TV services by allowing the reuse of spectrum, content and infrastructure. The results show that the incorporation of time interleaving (TI) at the physical layer for time diversity, and single-input multiple-output (SIMO) for space diversity are critical for the performance of mobile broadcasting systems. Upper layer FEC (UL-FEC) techniques can be used to achieve time diversity in first generation systems like DVB-T and DVB-H; however, they require the transmission of additional parity data and are not useful for stationary reception. The analysis in terms of link budget reveals that the combined use of time and space diversity is not sufficient to enable the provision of mobile services with acceptable coverage levels in DVB-T and DVB-T2 networks planned for fixed reception. In contrast, diversity techniques can be used in networks planned for portable indoor iii ABSTRACT reception to increase the capacity of vehicular services and extend the coverage of handheld indoor reception.The utilization of combined diversity in the time, frequency, and space domains has been investigated in the context of DVB-NGH, the first broadcasting system to exploit the diversity in the three domains by incorporating at the physical layer long TI, time-frequency slicing (TFS) and multiple-input multiple-output (MIMO). In addition, the adoption of rotated constellations provides better robustness against fading by means of signal-space diversity (SSD).DVB-NGH features an optional satellite component, and has adopted long TI in order to cope with the signal outages that are characteristic of land mobile satellite (LMS) channels. However, the solution adopted in t...
