“…A can be A (1) or A (2) for TS (1) or TS (2) respectively. A (1) and A (2) are (2N +1)×N and (N +1)×N matrixes respectively: At each iteration point R (k) , the next better feasible point R (k+1) is found to improve the objective value along a feasible direction. If the current feasible point exists inside the feasible region, the feasible direction will be the minus gradient of the objective function.…”

Digital Terrestrial Video Broadcasting (DVB-T) provides an ideal means for providing services with both high data rate and high mobility, which exceeds the ability of current access technologies like UMTS, WLAN, and so forth. Combined with other media as a return channel for user requests and acknowledgement signaling, DVB-T can provide interactive data services. In this paper, the integrated Internet and DVB-T network is proposed to provide broadband Internet access services for users with high mobility. In order to make effective use of valuable DVB-T resources, we present a bandwidth allocation algorithm SOBAM(Satisfaction Oriented Bandwidth Allocation Method), which is based on a new concept: user satisfaction. The simulation results powerfully show that SOBAM gives good QoS differentiation and make plentiful utilization of DVB-T available bandwidth. With SOBAM, the integrated Internet and DVB-T network can provide a soft system capacity which is similar to the one in CDMA networks.Keyword: DVB-T, integrated network, satisfaction, resource management Abstract-Digital Terrestrial Video Broadcasting (DVB-T) provides an ideal means for providing services with both high data rate and high mobility, which exceeds the ability of current existing access technologies like UMTS, WLAN, and so forth.

“…Digital Terrestrial Video Broadcasting (DVB-T) system is an ideal carrier for this kind of services( [1]), and integration of DVB-T and Internet will make possible that users at high speed are able to access the Internet with high data rate. DVB-T works unidirectionally and can only be applied to wideband data services in the downlink.…”

“…In SOBAM, with the continuously differentiable design of the satisfying functions, it is easy to see that the target function is also continuously differentiable. Besides, the column vectors of any submatrix of A (1) or A (2) are independent with each other. Hence, we have the conclusion that without iteration limit, SOBAM either stops at a Kuhn-Tucker point or generate an infinite sequence whose cluster points are all Kuhn-Tucker points.…”

DVB's second generation system for cable transmission -DVB-C2 -has been standardized in the beginning of 2009. This also set the starting point for the development of DVB-C2 equipment. Nevertheless, in the early stage a complete transmission chain for demonstrating DVB-C2 was not available. Therefore, we developed a DVB-C2 receiver employing a Software Defined Radio (SDR) approach. The system utilizes a standard PC and is able to decode an 8 MHz channel with 4096-QAM modulation in real-time. The developed receiver was used for the world's very first DVB-C2 transmission and will be extended to DVB-T2 in the near future.
