Video over Atm Networks
There will be quality requirements posed on network transfers of video information. They stem from the timing of the temporal sampling, and from perceptual limits on delay and loss that are given by the use of the transfers. Loss and delay exceeding these limits impede the information exchange between users and may render a service useless. This paper is a review of video communication over ATM...
متن کاملVideo Transport in ATM Networks
Video applications are expected to generate a signiicant proportion of the traac in the future B-ISDN. We consider the diierent possibilities for the transport of video signals provided by the service classes deened by the ATM Forum and the ITU-T, focusing attention on preventive rather than reactive control. The options available for statistical resource sharing are discussed in terms of Rate ...
متن کاملDesign of a transport coding scheme for high-quality video over ATM networks
In this paper, we explore the design of FEC-based error concealment schemes for digital video transmission on ATM networks. In particular, we study the impact of code selection on the overall performance and provide a judicious code selection strategy. The use of FEC provides an active and powerful means of recovery from packet loss which is particularly useful when the encoded video material h...
متن کاملVideo Transmission over Atm Networks 1.1.1 Introduction
In this chapter we will introduce the current state of the art, potential ben-eets and main challenges in establishing transmission of video over Asynchronous Transfer Mode (ATM) networks. ATM is likely to become the preferred transport technology within future Broadband Integrated Services Data Networks (B-ISDN), where ATM switching and multiplexing will be used to transport end-user traac end...
متن کاملEfficient Video Multiplexing Over ATM Networks
Variable Bit Rate video (VBR) allows statistical multiplexing in Asynchronous Transfer Mode Networks (ATM) while offering constant visual quality. In this paper we tackle the problem of defining video multiplexing schemes convenient for delay-sensitive video sources. A good characterization of VBR sources allows the implementation of efficient Connection Admission Control (CAC) and Police funct...
