| 摘 要： | INTRODUCTION With the development of the technology of A/D, DSP, optic fiber communication and broadband packet switching, integration of telephone, television and Internet will become a reality. Asynchronous transfer mode (Zhang and Qiu, 1997), different from common IP, is a connec-tion-oriented and fast packet switching technology using virtual connection technology and transfers data in cells of a fixed size. ATM integrates multiplexing and switching functions, is well suited for …

| Abstract: | This paper introduces a method to realize digital television transmission based on asynchronous transfer mode (ATM), a technology based on fast packet switching. Choosing the integral multiple length of an ATM cell payload to equal to the length of an MPEG transport stream packet, an MPEG transport stream packet can be inextenso loaded by several ATM cells and trans-formed into ATM cells. Using ATM virtual connection technology and B-ISDN, the interoperability between ATM and DTV may be realized, and DTV signal transmission may also be realized finally. |
