Abstract
Disclosed is a system for transmitting a digital video stream, which supports decoding of a scalable video coding (SVC) scheme, the system includes a transmission terminal and a reception terminal, wherein the transmission terminal includes an encoder for encoding a high-definition digital video stream and a division transmission unit for dividing the high-definition video stream having a predetermined time unit into a first divided high-definition video stream and a second divided high-definition video stream by reducing a frame rate and for transmitting the first and second divided high-definition video streams, and the reception terminal includes a transmission coupling unit for receiving the first and second divided high-definition video streams transmitted from the transmission terminal, coupling the received streams according to validity thereof, and transmitting the received streams as a reception high-definition digital video stream; and a decoder for decoding the reception high-definition digital video stream transmitted from the transmission coupling unit.
