<p>An apparatus and a method for converting control information are provided to perform a voice/video communication between terminals although types of capability information of the terminals are different. A converter(400) for converting control information or media information for video/voice communication is installed between the first and second terminals(301,302) which are connected to different networks. The converter(400) includes a control information converter(420), a transcoder(450) and a capability information converter(460), and when capability information extracted from decoded information received from the first terminal(301) is not identical to capability information extracted from control information received from the second terminal(302), the converter(400) checks whether screen sizes do not correspond to each other. If the screen sizes do not correspond to each other in one direction, the converter(400) converts a portion of the decoded information or the control information without operating the transcoder(450). When the screen sizes do not correspond to each other, the converter(400) operates the transcoder(450) to convert a beat stream.</p> |
