Abstract The present invention discloses a video encoding apparatus using a transmission control matrix and an operating method thereof. The video encoding apparatus transmits a source packet to M destinations using a transmission control matrix, classifies the packet into a state when the switching request information of an encoder is received from a destination where packet loss occurs and a state when the switching of the encoder is completed, and changes the component values of the transmission control matrix. So, the break of a video or interruption of a video flow is prevented during the conversion process of the encoder. One context switch and one copy are performed by a kernel space in a user space when the same source packet is sent to multiple destinations. So, load and power consumption are reduced. The video encoding apparatus includes an encoding part, first and second generation parts, and a communication part. 본 발명은 전송제어 매트릭스를 이용하여 M개의 목적지로 소스 패킷을 전송하고, 패킷 손실이 발생한 목적지로부터 인코더의 전환 요청 정보를 수신했을 때의 상태와 인코더의 전환 완료했을 때의 상태로 구분하여 전송제어 매트릭스의 성분값을 변경함으로써, 인코더의 전환 과정에서 영상이 깨지거나 영상 흐름의 끊김을 방지하고, 동일한 소스 패킷을 복수의 목적지로 전송할 때 사용자 스페이스에서 커널 스페이스로 한 번의 콘텍스트 스위칭과 한 번의 복사가 이루어지도록 함으로써, 부하와 소비전력을 감소시키는 영상 인코딩 장치 및 그 동작 방법을 개시한다.
