With the deployment of two ways HFC network and the development of digital TV, more and more interactive applications are being developed based on bi-directional HFC network. And the implementation of interactive cable set-top-box of digital TV is one of key component, which offers various interactive services based on TV display. In this paper, we(More)
Computer algebra systems such as Maple [2] and Mathematica [12] are good at symbolic computation, while theorem proving systems such as Coq [11] and pvs [9] are well-developed for creating formal proofs. However, people are searching for a mechanized mathematics system which can provide highly integrated symbolic computation and formal deduction(More)
With the popularity of broadband networks and development of digital home equipments, high-quality services in home network demand higher performance. However, the heterogeneous network and lack of effective end-to-end QoS mechanism in home network are major problems to develop high-quality services. In this paper, driven by high-quality services(More)
The paper proposes a converged architecture of home network and IMS based on home IMS gateway, gaping their heterogeneity and implementing convergence on data plane, control plane and management plane. Aiming at issues of interoperation, QoS and mobility, the architecture provides solution schemes, respectively. Through its implementation of modularized(More)
In this paper, we investigated the influence of asymmetric on TCP over HFC-based networks and related methods to improve the TCP performance. Then, a scheme called Modified Adaptive SACK Filtering is proposed to improve the TCP performance by adjusting the size of the block information in SACK option according to the real-time characteristics of network.(More)
Bandwidth smoothing can increase the utility of network bandwidth by reducing the burstiness of a VBR (variable bit rate) video stream. To guarantee the quality of service of video-on-command service in home network, data transmission rate should not exceed the maximum data handling capacity of embedded terminals. This paper designs a streaming media system(More)
