Zusammenfassung:	Provided are a device and method for multicast screen mirroring. The method for multicast screen mirroring includes the steps of: generating a compressed video frame by compressing a video frame; generating an encoding packet by encoding the compressed video frame with network coding; and transmitting the encoding packet with a multicasting method. Accordingly, the present invention can provide high expandability and high reliability in screen mirroring for multiple users. 멀티캐스트 스크린 미러링 장치 및 방법이 제공된다. 멀티캐스트 스크린 미러링 방법은 비디오 프레임을 압축하여 압축된 비디오 프레임을 생성하는 단계, 압축된 비디오 프레임을 네트워크 코딩 (Network Coding) 으로 인코딩하여 인코딩 패킷을 생성하는 단계 및 인코딩 패킷을 멀티캐스트로 전송하는 단계를 포함하는 것을 특징으로 한다.
