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.
