SUMMARY This letter presents the design and implementation of a video streaming file server system, which has been implemented in the context of a distributed digital multimedia broadcasting environment that has been prototyped. To make a performance analysis of file systems and distributed object services for continuous media (CM) provisioning, we validate the performance of the system against...

The constellation rotation and cyclic quadrature component delay (RQD) technique has been adopted in the second generation terrestrial digital video broadcasting (DVB-T2) standard. It improves the system performance under severe propagation conditions, but introduces serious complexity problems in the hardware implementation of the detection process. In this paper, we present a simplified schem...

This paper presents a computationally efficient iterative Reed-Solomon (RS) decoder, which is suitable for software implementations on processors with instruction extensions for Galois field multiplication. Simulation models of proposed instructions were included into a processor simulator and performance of RS decoding was analyzed. The method has been validated for both Digital Video Broadcas...

Ki-Dong Lee et al. 211 This paper presents a dynamic resource allocation algorithm with multi-frequency time-division multiple access for the return link of interactive satellite multimedia networks such as digital video broadcasting return channel via satellite systems. The proposed timeslot assignment algorithm, called the very efficient dynamic timeslot assignment (VEDTA) algorithm, gives an...

The duals of finite impulse response filters constructed of binary matrix sequences are used to design an eight-channel transmultiplexer. The binary matrix sequences of analysis and synthesis filters are obtained from corresponding complementary sequences which satisfy the conditions for perfect reconstruction. The distortions of eight transmultiplexed images in the presence of channel noise ar...

A low-cost passive bistatic radar system using digital video broadcasting satellites (DVB-S) as illuminators of opportunity is presented. The system was developed using off-the-shelf components which a global cost of approximately 100 Euros. To increase the target detectability using DVB-S signals in a non-coherent environment a novel methodology, using a reference target and some basic signal ...

A novel design methodology for the implementation of control units for application specific instruction set processors (ASIPS) is described. This methodology uses automatic instruction encoding and semi-automatic generation of the hardware instruction decoder to speed up the ASIP design. Significant power savings due to optimized instruction encoding are achieved. Results for ICORE (ISS-Core), ...

To improve the quality of the mobile reception of DVB-T (Digital Video Broadcasting on Terrestrial networks) signal, the knowledge of the propagation channel characteristics is necessary. In this aim, this paper presents sounding methods and results for the estimation of Direction of Arrival (DoA) of DVB-T signals in mobile receiving configuration. The mobile passive sounder is presented, inclu...
