System and method for transmitting digital video stream using SVC scheme

A method for transmitting a digital video stream, which supports decoding of a scalable video coding (SVC) scheme, the method comprising the steps of:

• a) encoding a high-definition digital video stream to generate an encoded video stream including a plurality of consecutively arranged group of pictures (GOP) sets, each GOP set including at least one GOP, each GOP including an I (Intra) Frame and a plurality of P(predicted) frames;
• b) 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, even-numbered GOP sets and odd-numbered GOP sets to the first and the second divided high-definition video streams, respectively, 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
• c) transmitting the first and second divided high-definition video streams using different transmission frequencies, wherein said GOP sets in said first and second video streams are transmitted simultaneously by delaying one stream with respect to the other by a known time, the known time corresponding to a number of consecutive GOPs associated with the selection and assigning of said GOP sets to corresponding ones of the first and second video streams;
• 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.

A method for processing a high-definition digital video stream, which supports decoding of a scalable video coding (SVC) scheme, the method comprising the steps of:

• receiving first and second divided high-definition video streams transmitted using different transmission frequencies;
• determining if an error has occurred in at least one of the first and second divided high-definition video streams;
• if there is no error in the first and second divided high-definition video streams,
• generating a first reception high-definition digital video stream by coupling the first and second divided high-definition video streams, wherein the first reception high-definition digital video stream includes a plurality of consecutively arranged group of pictures (GOP) sets, each GOP set includes at least one GOP, each GOP includes an I (Intra) frame and a plurality of P (predicted) frames, the first divided high-definition video stream including only even-numbered group of pictures (GOP) sets of the first reception high-definition digital video stream, and the second divided high-definition video stream including only odd-numbered group of pictures (GOP) sets of the first reception high-definition digital video stream, and the even-numbered group of pictures (GOP) sets and the odd-numbered GOP sets are alternately disposed in the first reception high-definition digital video stream;
• if there is an error in one of the first and second divided high-definition video streams, generating a second reception high-definition digital video stream using only that one of the first and second divided high-definition video streams not having the error;
• decoding one of the first and second reception high-definition digital video stream;
• 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.
