Patent ID: 8526505

Claim:
A system for processing a digital video stream, which supports decoding of a scalable video coding (SVC) scheme, the system comprising: an encoder for encoding a high-definition digital video stream; and a division transmission unit for: dividing the encoded high-definition video stream having a predetermined time unit into two halves thereof comprising a first divided high-definition video stream and a second divided high-definition video stream by selecting and assigning, in an alternating manner, at least one group of pictures (GOP) to the first and second video streams, each GOP including an I frame and a plurality of P frames, wherein each of the first and second divided high-definition video streams has the same number of I frames and the same number of P frames, and each GOP of the first and second divided high-definition video streams has a single I frame and the same number of P frames, and wherein a frame rate of each of the first and second video streams is one-half a frame rate of the encoded high-definition video stream, and delaying the second video stream by a known time with respect to the first video stream, said known time corresponding to a number of consecutive at least one group of pictures being selected and assigned to corresponding ones of the first and second video streams, wherein the known time causes the GOPs in corresponding ones of the first and second high-definition video streams to be aligned so as to be transmitted at a same time; and transmitting the first and second divided high-definition video streams, wherein said GOPs are transmitted simultaneously using different transmission frequencies for the first and second video streams.
