“…Based on these two policies, different resource optimization algorithm should be applied. Currently, we found that most optimization algorithms are based on the assumption that all data to be sent already exists in the DVB radio station server( [3], [5], [6]), which means they all follow policy 1, and no algorithm considering the characteristics of the coming Internet data streams is found yet. Hence, the current existing algorithms may not be fit for more real-time demanding services which prefer policy 2 in BNCC and they won't be able to fully exploit the BNCC resources.…”

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. Combined with other media for the uplink as a return channel for user requests and acknowledgement signaling, DVB-T can supply interactive data services. In this paper, we show the architecture of integrated Internet and DVB-T network to provide interactive broadband Internet access services for users with high mobility. In order to fully exploit the valuable broadcast resources and provide services with effective QoS differentiation, we present a bandwidth allocation algorithm SOBAM(Satisfaction Oriented Bandwidth Allocation Method) based on a new concept: user satisfaction.

“…Digital Object Identifier 10.1109/TBC.2003.817084 rate control mechanisms have been designed separately for DTV and IP services [3], [4]. However, within a composite multiplex combining television and IP traffic, there is a need of a more generalized bandwidth management scheme which can be in real time applied to all services, regardless of their nature.…”

The combination of high capacity, signal robustness, and worldwide acceptance have made digital terrestrial broadcasting (DVB-T) one of today's more promising technologies, while newly adopted standards support the integration of digital television programs and data services within a single multiplex, offered to both stationary and mobile end users. This paper addresses the issue of optimal bit rate allocation among DTV and IP services within the DVB-T multiplex, and demonstrates a novel configuration providing real-time sharing of the available bandwidth via an algorithm based on service hierarchy and perceptual quality assessment. The architecture and performance of a fully functional DVB-T testbed developed on this concept is also presented.

“…A simple example of such applications is intemet/WWW access while watching TV. The advancements of the network infrastructure and the introduction of new services [7] require modifications of the software architecture of currently available STBs. Their software architecture and implementation shows a strong monolith structure [ll].…”

Currently available Set-Top-Boxes (STBs) are mainly used for digital TV reception. The User Interface (UI) and the U1 dialog of such a device usually focus on its technological aspects and to a large degree ignore the needs of the user. The impact is that the user quite often is unsatisfied when interacting with the device. Recent U1 design approaches [9] [10] are proving that the focus should be put on the tasks that the user can perform with a STB rather than its underlying technical capabilities.However, modem design approaches both for the STB U1 as well as its underlying system architecture can be incorporated into a complete system design with reasonable effort. This paper presents the architecture of the "d-box", a STB being used for broadcasting TV services as well as future interactive services like internet, home-shopping etc. in Germany. The layered software architecture employs a Java Virtual Machine offering a high degree of independency of its underlying hardware. Emphasis is put upon the user-friendliness of the device by providing a uniform U1 both for experts and novices, therefore allowing intuitive and easy access for different user groups.
