An apparatus and method to transmit a packet to provide a multimedia streaming service to one or more terminals connected through a network includes a contents producing unit, a contents storing unit, and a packetizing unit. The contents producing unit encodes and compresses multimedia data into bit streams. The contents storing unit stores the bit streams compressed by the contents producing unit. The packetizing unit packetizes the bit streams stored in the contents storing unit in a predetermined coding format, and packetizes the bit streams in a different coding format when a state of the network changes.

1. Field of the Invention
The present invention relates to an apparatus and a method to transmit a packet for a multimedia streaming service, and more particularly, to an apparatus and a method for transmitting a packet for a multimedia streaming service which applies a modification of a coding format to a packetizing process according to a state of a network.
These and/or other aspects and advantages of the invention will become apparent and more readily appreciated from the following description of the embodiments, taken in conjunction with the accompanying drawings of which:
FIG. 1 is a structure view illustrating a network system using an apparatus to transmit a packet for a multimedia streaming service, in accordance with a first aspect of the present invention;
FIG. 2 is a flowchart showing a method to transmit the packet for the multimedia streaming service, in accordance with the first aspect of the present invention;
Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout. The embodiments are described below in order to explain the present invention by referring to the figures.
FIG. 1 is a structure view illustrating a network system using an apparatus to transmit a packet for a multimedia streaming service, in accordance with a first aspect of the present invention.
Referring to FIG. 1, a server 10 transmits data streams to terminals 20 through a network 30 by using a real time streaming protocol (RTSP). The server 10 includes a contents producing unit 11, a contents storing unit 12, a packetizing unit 13, and a network interface unit 14.
