A technique for transmitting a video stream between a first electronic device and a second electronic device is provided. The first device receives an encoded video stream and determines whether an encoding format of the encoded video stream is a format decodable by a second electronic device. If the format is decodable, the encoded video stream is transmitted without a re-encoding operation to the second device. The video stream is displayed at the first device delayed by a determined delay time enabling the video stream to be displayed at the second device substantially synchronized with the display at the first device.

Method for transmitting stream between electronic devices and electronic device for the method thereof

A network access method of Wireless Local Area Network (WLAN) terminals and a network system thereof which are designed to support network association between a terminal and an Access Point (AP) in an IEEE 802.11 WLAN environment includes: scanning at least one AP in the network and determining whether or not the AP uses a Wired Equivalent Privacy (WEP) Key; and converting to an Open System authentication mode or a Shared Key authentication mode according to the determination. Accordingly, the terminal can scan for the existence of a WEP Key from at least one AP and convert into a network-accessible Open System authentication mode and a Shared Key authentication mode so as to execute an association.

Network access method of wireless local area network (WLAN) terminals and network system thereof

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).

Method and system for sending video signal between different types of user agents

An IP based voice/video communication system and call pickup/forwarding method and a program storage device, readable by a machine, tangibly embodying a program of instructions executable by the machine to perform the call pickup/forwarding method enables a subscriber can have voice/video communication irrespective of time or place by forwarding voice/video calls between voice/video communication terminals such as a TV, PDA and home pad, or by picking up a incoming call at a nearby terminal if it is difficult for the subscriber to answer the call at the originally called terminal from his/her location.

IP-based voice/video communication system and call pickup/forwarding method

A packet processing terminal and method for compressing a header of a packet. When it is determined an IP header is to be compressed in order that a terminal removes overhead of a generated packet, an IP header compression option is added to a socket option of a socket generated in order to exchange the packet between an application module and an OS module. And, when the application module sets the IP header compression option, the IP header of the packet is compressed by the OS module using a compression method corresponding to option information of the set IP header compression option.
