Abstract: A method of transmitting and receiving a data frame supporting a video MAC protocol and a system thereof are provided to use contents having error partially, thereby reducing waste of network resources due to contents retransmission. A video MAC(Media Access Control) support terminal determines whether a video MAC protocol is supported(S210). A video MAC data frame is received so that the video MAC support terminal determines whether error exists in a header. If the error does not exist in the header, the received video MAC data frame is provided to a user without respect to that error exists in a body(S240).

Abstract: 본 발명은 무선 LAN 시스템에 있어서, 무선 LAN 액세스 포인트(Access Point)를 통하여 이더넷(Ethernet)에 접속시키는 무선 이동 단말 장치의 매체접근제어 처리 장치(MAC Device)에 관한 것이다.
종래 매체접근제어 처리 장치 구조는 물리계층에서 만들어진 프레임(MSDU : MAC Layer Service Data Unit) 처리가 동기식 버스제어 방식으로 이루지기 때문에 원래 MAC(Media Access Control)이 비동기식 데이터 서비스와 동기서비스를 모두 지원하는 특성을 효율적으로 처리를 못하여 단말기 성능 효율을 저하시켰다.
따라서, 본 발명은 물리계층에서 만들어진 프레임(MSDU)을 비동기식 버스제어 방식으로 처리할 수 있는 비동기식 버스형태의 매체접근제어 처리 장치를 제공한다. 본 발명에 의한 비동기식 버스형태의 매체접근처리장치는 클럭스큐, 클럭동기화에 대한 문제가 없어 지연요소에 민감 하지를 않아 고속 처리에 유리하다.
