Asynchronous transfer mode communication method Real time video data processing device in network interface card

摘要

The present invention relates to an asynchronous transfer mode communication method network interface card (NIC), wherein a virtual path identification number (VPI) of header information of an ATM cell from a physical layer chip (22) of an asynchronous transfer mode communication network interface card a moving picture data detection means (18) for detecting real time video cell data by a virtual path identifier (VCI) and a virtual channel identifier (VCI); First and second storing means (14, 16) for storing moving picture cell data from the moving picture data detecting means (18); The header of the real-time video cell data stored in the first and second storage means 14 and 16 and the header of the protocol data unit (PDU) of the AAL layer common part convergence sublayer (CPCS) A decoder interface unit (12) for forming a transport packet (TS) after removing a header and a trailer; And a decoder 10 for decoding the transmission packet TS from the decoder interface unit 12 and outputting a video signal.
