The present invention relates to a media transmission system wherein a server selects an image frame having an image number nearest to play position information and a high compression ratio, and transmits the image frame to a user terminal when the user terminal transmits desired play position information to the server while media data streaming is being performed from the server to the user terminal, thereby moving to the scene desired by a user and playing the scene in a simple manner. The present invention also relates to a method for same. The media transmission system according to the present invention includes: a user terminal for receiving, from a user, desired position information for the media data being streamed and played, transmitting the position information, and receiving the image stream matched to the position information and playing the image stream; and a media server for searching the image stream having a high compression ratio among the image streams nearest to the position information, and streaming the searched image stream to the user terminal when the position information is received from the user terminal after streaming media data to the user terminal. The present invention provides a user with more random access points so that the user may select and view the desired scene while viewing a motion picture, prevents the degradation of the compression ratio by providing more random access points, and enables a user to easily change and view the desired scene while viewing media content. |
