摘要:
A method for exchanging media description information between user agents using a session initiation protocol (SIP) comprises the steps of: providing information on an OS and sound module of a first user agent so that the first user agent generates, in a media description field of a session description protocol (SDP), an SIP message including the information on the OS and sound module of the first user agent, and sends it to a second user agent; and setting a processing format for voice data of the second user agent so that the second user agent determines the voice data format supportable by the first user agent from the information on the OS and sound module of the first user agent, compares it with the voice data format supportable by the second user agent, and sets a format commonly supportable by the first and second user agents as the voice data format of the second user agent.

In a method and system for providing selective media data in a multimedia conference service, a selective media data provision request of a participant who wants to be selectively provided with media data is transmitted to a media server using Session Initiation Protocol (SIP), and media data selected or converted according to the request to the user are provided, thereby improving user convenience.
摘要:
A method for scaling a display size between different types of user agents. The method includes exchanging session initiation protocol messages including media information when performing a call setup for setting up a media session between the user agents; determining any one of the user agents to scale the display size from the exchanged media information; and scaling, by the determined user agent, the display size on the basis of the media information, and sending video data subject to the scaling to the other user agent(s).

摘要:
Disclosed are an apparatus and method for communication using an icon. A first communication terminal of a first user stores a second user icon profile including an icon(s) representing at least one communication terminal used by a second user and a second communication terminal of the second user stores a first user icon profile including an icon(s) representing at least one communication terminal used by the first user. When the first user a first icon from the at least one icon forming the second user icon profile, the first user can communication with the second communication terminal of the second user represented by the first icon using the first communication terminal.

An image processing apparatus and method are adapted to form an image of an object photographed by a camera at a preset resolution; crop a preset portion from the image; and display the cropped image portion in response to a request from a user. Then, the specific image portion can be zoomed or magnified without degradation of image quality and the zooming power or magnification can be adjusted by cropping and size-adjustment of the specific image portion.

The method for controlling a hybrid air conditioning system of a direct coupled motor-driven hybrid electric vehicle includes detecting operating conditions of the air conditioning system; and controlling the hybrid air conditioning system. The hybrid air conditioning system includes a mechanical air conditioner driven by an engine and an electric air conditioner driven by electric power of a battery.
