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: PURPOSE: An apparatus for providing streaming contents and a method thereof are provided to efficiently divide media information in active HTTP streaming by using general media information and specific media information. CONSTITUTION: A terminal(110) receives meta data of a media or the meta data about a specific cycle of the media from a server(100)(610). The terminal processes the meta data about the specific cycle(620). The terminal extracts information provided through the meta data. The terminal requests a server of segments(630). The server extracts a data part suitable for the requested segments if there is a need to parse a media(640). The server transmits the segments suitable for each request from the terminal to the terminal(650). The terminal plays the media by decoding and rendering data in the media included within the segments(660).

Abstract: PURPOSE: A transcoding system and method for CELP(Code Excited Linear Prediction) CODECs having different bandwidths are provided to reduce sound quality deterioration and decrease delay and the quantity of calculations. CONSTITUTION: A transcoding system includes a Formant parameter converter(32), a Formant factor quantizer(34), an excited signal parameter converter(36), and an excited signal quantizer(38). The Formant parameter converter converts a Formant parameter coded in an input CELP format into an output CELP format to generate an output Formant parameter. The Formant coefficient quantizer receives a Formant filter factor in the output format from the Formant parameter converter to quantize the Formant filter factor in the format used by an output CELP CODEC. The excited signal parameter converter converts an excited signal parameter coded in the input CELP format into the output CELP format to generate an output excited signal parameter. The excited signal quantizer quantizes the excited signal parameter in the output CELP CODEC format.
