Design and implementation of an end-to-end system importing DTV from broadcasting network to broadband IP network
This paper describes design and implementation of an end-to-end system which implements digital television (DTV) broadcasting to broadband IF' networks. We have developed a DTV-IF' gateway for introducing DTV program from broadcasting headend into IF' network with special considerations of the challenges, which consist of transmitting DTV in the IP network environment and different transmitting protocols between the traditional satellite, cable or terrestrial network and the broadband IP network. Moreover, we have proposed a method to auto-regenerate the standard transport stream (TS) packet for the standard set-top-box (STB) with consideration of timing synchronization. This end-to-end system has been verified to work well in the broadband IP network environment.
