| Abstract: | This paper presents an implementation of IP multicasting technology in a digital video monitoring system and discusses the key techniques involved. issues discussed include the construction of IP multicasting flow, IP multicasting based on winsock, options of protocols in transport layer, network runoff control strategy and the implementation of user access control. MPEG-1 compression coding is realized by means of software and with a digital chip 21230, and decoding is realized only by means of software. The software is developed with Visual C on a Windows g-c/NT platform. IP multicasting can make full use of the current bandwidth and therefore has a wide range of potential applications. |
