If the network of city or county can be unified,we can distribute value-added services by the total front-end and front-end.We usually build up a datacasting system in center engine room to broadcast the overall,comprehensive and universal content.And a subsidiary of counties needn't to build their own sub-division.They can receive the contents of the total front-end through the network adapter,re-appliances,modulators and other equipment.Then they can transmit the contents to their users through their own HFC network.In this way,we can make full use of the datacasting network resources of the total front-end.At the same time,the city datacasting network remains the counties (cities) private page for their own contents.
