| 摘要 |
The present invention relates to a Cable Television (CATV) that includes a head end with a radio-frequency hub and an Ethernet hub to separately process data transmitted within the CATV. Specifically, the radio-frequency hub receives the data, extracts radio-frequency data therefrom, outputs the extracted radio-frequency data, and transmits the data to the Ethernet hub, which is external to the radio-frequency hub. The Ethernet hub receives the data from the radio-frequency hub, extracts Ethernet data from the data, outputs the extracted Ethernet data to an Ethernet data port, inputs additional Ethernet data from the Ethernet data port, incorporates the additional Ethernet data into the data, and transmits the data, with the additional Ethernet data incorporated therein, to a receiver.
