Disclosed is a processing method which enables natural reproduction upon the occurrence of representation switching during the transmission of an HTTP stream. The method comprises the following steps: constructing, for a first representation and from base layers of scalable video coding, a plurality of segments; constructing, for a second representation which has a higher quality than the first representation and from enhanced layers of scalable video coding, a plurality of segments; and transmitting at least a portion of the plurality of segments for the first representation in the event of transmitting the first representation, and transmitting at least a portion of the plurality of segments for the second representation together with at least a portion of the plurality of segments for the first representation in the event of transmitting the second representation. According to the present invention, only base layers may be extracted from the second representation and used as a reference in decoding low bit-rate segments to be reproduced in the future, thus providing multimedia content that is seamlessly displayed upon the occurrence of representation-switching. |
