Abstract: PURPOSE: A jumping method in a video-on-demand system for transmitting stream data using a multicasting channel is provided to minimize utilization of the multicasting channel and effectively process jumping. CONSTITUTION: A client(201) sends a session ID and a jump position to a video server(205). The video server checks if the range of the jump the client wants is within a patching interval. When the jump range is within the patching interval, the video server checks if the jump is possible using data stored in a disc of the client. When the jump is possible, the video server controls a patching length. When the jump range is not included in the patching interval, the video server generates a new channel. The client selectively receives a normal channel(202), a patching channel(203), a patching length, and a standby time whenever the patching length controlling step and the new channel generating step are performed.
Abstract translation: 目的：提供使用多播信道发送流数据的视频点播系统中的跳转方法，以最小化多播信道的利用并有效地处理跳转。 构成：客户端（201）发送会话ID和跳转位置给视频服务器（205）。 视频服务器检查客户端需要的跳转范围是否在修补间隔内。 当跳转范围在修补间隔内时，视频服务器使用存储在客户端的光盘中的数据来检查跳转是否可能。 当跳转可能时，视频服务器控制修补长度。 如果跳转范围未包含在修补间隔中，则视频服务器将生成一个新通道。 每当执行修补长度控制步骤和新的信道生成步骤时，客户端选择性地接收正常信道（202），修补信道（203），修补长度和待机时间。

Abstract: PURPOSE: A method of fast mode decision of an enhanced layer using a rate-distortion cost in an SVC encoder, and an apparatus thereof are provided to remove an unnecessary motion mode for a current macro block of an upper layer by using motion detection information of a previous frame and the motion detection information of a lower layer. CONSTITUTION: Bit rate distortion values for a current macro block of an enhanced layer and a previous block are calculated(S100). A final bit rate distortion value for the previous macro block is calculated by compensating the bit rate distortion value for the previous macro block as the compensating value for reflecting the correlation with a previous video frames(S200). The bit rate distortion value for the current macro block is compared with the final bit rate distortion value to select a motion mode excluded from the current macro block(S300).

Abstract: An FGS(Fine Granular Scalability) coding/decoding method and a device thereof are provided to first compress a macro block having a high degree of importance, thereby remarkably improving FGS compression efficiency. Important factors and priorities of the important factors are set(S301). Information on important factors about macro blocks of a frame is extracted(S302). An important macro block map is generated by determining order of importance degrees for each macro block according to the extracted important factor information and the set priorities(S303). An FGS-based coding process is carried out in order of the importance degrees of the macro blocks of the frame by using the important macro block map(S304).

Abstract: 본 발명은 비디오 인코더에서의 인터 모드 결정 방법에 관한 것이다.
본 발명의 비디오 인코더는 인터 모드를 결정하기 위하여, 이전 프레임의 인터 모드 정보를 이용하여 초기 후보 모드들을 선택한다. 또한, 이전 프레임에서 현재 매크로블록과 최대 상관도를 보이는 매크로블록을 추정하고, 해당 매크로블록의 율-왜곡 비용과 초기 후보 모드들 중에서 선택된 모드의 율-왜곡 비용을 비교하여 인터 모드 결정 과정을 조기 종료할 것인지를 선택한다. 만약, 조기 종료 조건이 만족되면, 초기 후보 모드들 중에서 최소 율-왜곡 비용을 가지는 후보 모드를 현재 매크로블록의 인터 모드로 결정하고, 인터 모드 결정 과정을 조기 종료한다. 반면에, 조기 종료 조건을 만족하지 못하면, 추가 후보 모드들을 선택하여 인터 예측 과정을 추가로 수행하고 이에 따라 결정된 최소 율-왜곡 비용을 가지는 후보 모드를 현재 매크로블록의 인터 모드로 결정한다.
