| Abstract: | This paper introduces a Video on Demand system based on both CATV broadcasting channels and IP interactive network. CATV broadcasting channels are used for content transmission and IP network is used for control information transmission between Set Top Box and I-leadend Server, The control mechanism of whole system is designed and implemented according to DSM-CC protocol stacks. The paper narrates the end-to-end system diagram and VoD application software of Set Top Box. The system can be used in CATV network and provide VoD services for CATV subscribers. |
