Network apparatus and method to provide compressed digital video over mini-fiber nodes |
摘要 |
A communication network and method is provided to communicate between a central office/head end and a plurality of end-units (EUs). A first transmission medium is connected between the central office and an intermediate node. A plurality of second transmission mediums are connected between the central office and a plurality of mini-fiber nodes. The intermediate node is also associated with each of the mini-fiber nodes such that an analog broadcast service may be sent over the first transmission medium to each of the mini-fiber nodes. Further, switched digital services and digital broadcast services are also sent over the second transmission mediums to each of the mini-fiber nodes. The mini-fiber nodes combine the signals and send the combined signals to a corresponding subset of EUs.
