Abstract: Provided are a method and apparatus for a user equipment, a core network, and a second device to enable bidirectional communication for second devices. The method of the second device may include receiving internet protocol (IP) configuration information for automatically configuring an IP version 6 (IPv6) address of the second device from a core network through a user equipment; generating the IPv6 address using information in the IP configuration information; and transmitting the generated IPv6 address to the core network through the UE.

Abstract: Provided are a method and apparatus for providing a network switching service to a user equipment.

Abstract: A display apparatus includes: a display for displaying an image; a detector for detecting an exposure speed of a portable image-forming device which exposes an instant film to light using light from a screen displayed on the display; and an image processor for adjusting brightness of the image displayed on the display depending on the detected exposure speed.

Abstract: A portable image-forming device includes a housing, an exposure member for exposing an instant film disposed inside of the housing by means of a light radiating from the screen of a portable display device, a shading member linked in movement with the exposure member so as to shade the instant film, a traction member connected to the exposure member so as to move the exposure member to a pre-exposure position, and a developing-agent-spreading member for spreading a developing agent, which is provided on the instant film, over the entire instant film. The traction member and the developing-agent-spreading member are manually operated by a user.

Abstract: A reel table driving device for use in a video cassette recorder comprises a pair of idlers disposed adjacent to a supply reel table and a take-up reel table in order to minimize the travelling distance thereof as a support plate for rotatably holding the idlers is rotated by the conversion of the operating mode, said idlers being constructed of a stepwise relationship with each other so that each reel table generates a sufficient torque during the switching of the operation mode, thereby preventing slackness of a loaded magnetic tape.
