摘要：
Provided are an apparatus and a method for multimedia data transmission in a cable network using a broadband and physical layer frame structure. The apparatus includes an external network matching module for transmitting data inputted/outputted from/to an external network to a Data Over Cable Service Interface Specification (DOCSIS) Media Access Control (MAC) layer, a DOCSIS MAC processor for transmitting the data from the external network matching module to a corresponding destination, a first downstream physical layer processor for handling an existing standard transmission in the data from the DOCSIS MAC processor, a second downstream physical layer processor for dealing with a new broadband transmission in the data from the DOCSIS MAC processor, and an upstream physical layer processor for providing received data to the DOCSIS MAC processor.
