Abstract
Disclosed is a transcoding method and apparatus for a mobile communication system provided with a transcoder. The transcoding method includes receiving a request for media content and codec information required for the requested media content, receiving the requested media content from a media content server and determining whether the received codec information exists, transformatting a format of the received media content by a codec of the codec information if the received codec information exists, searching the codec list and installing the codec information and transformatting the format of the received media content using the installed codec, determining whether a transmission bandwidth through which the transformatted media content are transmitted is smaller than a bandwidth of the transformatting codec, transrating the format of the media content by a codec suitable for the transmission bandwidth if the transmission bandwidth is smaller than the bandwidth of the transformatting codec, and transmitting the transrated media content.
