    The multilevel hierarchical network architecture has been shown to be a scalable and cost efficient solution for large video-on-demand (VOD) systems. The predominant operation cost of a hierarchical VOD system consists of network transmission cost and video storage cost. How to minimize the operation cost under several operating constraints is an important issue. Many operating constraints, such a... View full abstract»

    The operating Es/No of the European Digital Video Broadcasting over Satellite (DVB-S) system can be reduced by utilizing turbo codes, although this reduces the performance of both carrier and symbol synchronizers. While maximum likelihood decision directed (ML-DD) feedback algorithms for both carrier and symbol synchronization can be shown to approach the Cramer-Rao bound (CRB), at reasonable Es/N...

    Starting out with a strong justification for phase synchronization, we derive the symbol error probability for 8-vestigial sideband (VSB) in the presence of phase errors and compare it with the symbol error rates for 8-PAM and 64-QAM. Monte Carlo simulations support the theoretical expressions. Phase misadjustments lead to error floors, which are computed, and which further reveal the susceptibili... View full abstract»

    Wide scale power outages can cause serious disruptions to digital services over community antenna television (CATV) networks. This can result in long service recovery times for some or all of the cable modems (CMs). In this paper, the recovery mechanisms of the Data Over Cable Service Interface Specification (DOCSIS) protocol, due to service disruption, are studied. We propose a new scheme for the...

    This paper presents a new data broadcasting technique for transmitting data using the orthogonal frequency division multiplexing modulation scheme, within the NTSC television signal. The data signal is inserted in the vestigial sideband of the video signal. The advantages of this implementation are that the shape of the data spectrum minimizes the degradation of the picture quality and increases t... View full abstract»

    For a progressive scanning image source, a new scanning conversion system has been studied to attain a high picture-quality with higher vertical and horizontal resolution just as a high-definition image source. It has already been clarified by Kataoka et al. (1996) and by Furuhata et al. (1997) that in a cathode-ray tube (CRT) display the traditional progressive scanning system which employs a hig...
