Abstract: Provided is an apparatus and method for transmitting and receiving a streaming service. An inter-arrival jitter may correspond to a delay variation in arrival time between TCP packets arriving at an apparatus for receiving the streaming service. The apparatus for receiving the streaming service may determine a de-jitter buffering time to absorb a network jitter before TS packets in a TCP packet is input to a T-STD buffer model. Based on the de-jitter buffering time, an initial playout delay lime at the apparatus for receiving the streaming service may be determined.

Abstract: A method and a device for processing a boundary with peripheral block information in a scalable imaging encoder/decoder are provided to offer previously restored information of an upper layer as boundary information, which is needed for enlarging a block corresponding to a lower layer through down-sampling, when a small lower layer is encoded and decoded. A macroblock mode determiner(120) determines a macroblock mode of a lower layer when a scalable image is encoded/decoded. A boundary pixel information generator(130) generates boundary pixel information by performing down-sampling according to an up-sampling ratio with protected information of a block close to the macroblock of an upper layer when the macroblock mode of the lower layer is an internal mode. An up-sampler(140) performs up-sampling of the lower layer based on the boundary pixel information.
