An address management method and a video apparatus using the same are provided. The address management method includes determining whether an external device is connected or not; when determining the connection to the external device, generating an invalidation message for invalidating an address; and transmitting the generated invalidation message to the external device. Accordingly, when the port connection is changed, the physical address can be correctly updated by invalidating the former physical address.

Address management method and video apparatus using the same

A method for providing coordinate information to an external device and a video apparatus thereof. The coordinate information providing method includes receiving coordinate information input by a user from an input device; and transmitting a coordinate information delivery message containing the coordinate information input through the input device, to an external device connected according to a High Definition Multimedia Interface (HDMI) Consumer Electronics Control (CEC) specification. Accordingly, the video apparatus can control the external device by transferring the coordinate information to the external device.

Coordinate information providing method and video apparatus thereof

An address management method and a device thereof are provided. The address management method includes determining by a device whether all logical addresses corresponding to a type of the device are currently being used by external devices; setting by the device a non-use logical address as a logical address of the device, if it is determined that one of the logical addresses is currently not in use; and setting by the device a predetermined logical address as a logical address of the device, if it is determined that all the logical addresses are currently being used. Therefore, logical addresses may be allocated to a device even if all logical addresses corresponding the type of the device are currently being used.

Method for managing logical address and device thereof

A video signal processing system for a double deck VTR which can accomplish the simultaneous recording/playing function in both video decks and the dubbing function between two types of video tapes, wherein input/output select switches and input/output analog switches are located for appropriately processing the video signal between the respective devices of the double deck VTR.

Video signal processing system for double deck tape recorder

A method for selecting made by one key in the camera recorder is disclosed. The mode selecting method comprises a first step for changing the present mode into the temporary stop mode, the stop mode or the reproduce mode after reading the present mode when one key is pressed one time, a second step for changing the present mode into the fast forward mode or the forward picture search mode after reading the present mode when one key is pressed two times, a third step for changing the present mode into the rewind mode or reverse picture search mode after reading the present mode when one key is pressed three times, and a fourth step for changing the present mode into the standstill picture mode or the record check mode after reading whether one key is pressed the predetermined time or over.
