With the improving technology on multimedia data transmission and processing, Video-On-Demand (VOD) service over CATV networks has been probable nowadays. In this thesis, we discuss several design issues for this kind of service, including the multiplexing and de-multiplexing of MPEG-II programs, transport protocol on cable network, and Electronic-Programming-Guide(EPG) of this system. We may apply some related standards to achieve these goals. For example, we may employ the MPEG-II system layer standard that addresses the way to multiplex several MPEG-II programs into a single transport stream and the relative way to de-multiplex this transport stream at the remote site(STB). Moreover, associating the multiplexing skill with digitization technology over CATV would enable the system server to support more VOD channels simultaneously. On the other hand, MPEG-II conditional access functions and DVB data scrambling mechanisms both provide the secure access function. In addition to an effective transport protocol and system EPG, a highly interactive VOD service with friendly graphic interface will be represented to the system users.
