A multi-band built-in antenna of a portable terminal is provided. The antenna includes a first antenna radiator on a front surface of a substrate (e.g., a main board), and a second antenna radiator on an opposite surface of the substrate. The substrate has ground surfaces on both sides separated from a non-ground area on which the radiators are disposed. The first radiator may be in the form of a Planar Inverted F Antenna (PIFA), with a first end branched off into two parts, one part used for power feeding and the other part electrically coupled to the ground surface. The first radiator has a portion that extends from the first end to an opposite end. The second radiator is continuous from the opposite end of the first radiator through a via (hole) in the main board.

An apparatus for transmitting compressed video data includes a data interfacing circuit, a data connecting circuit, a decompression unit, and a CPU. The data interfacing circuit receives and stores compressed video data, generates a first control signal in response to receipt of the compressed video data, identifies an address bus and a data bus used for transmitting the compressed video data and then generates a hold permission signal in response to receipt of a hold request signal. The data interfacing circuit also provides output of the compressed video data in response to receipt of an address control signal. The decompression unit generates a data request signal to request input of said compressed video data. The decompression unit receives the compressed video data from the data interfacing circuit and decompresses the compressed video data to generate a motion picture in response to receipt of a data permission signal. The data connecting circuit generates the hold request signal in response to receipt of a second control signal and the data request signal, generates the address control signal in response to receipt of said hold permission signal, and generates a transmission state signal indicating that transmission of the compressed video data to the decompression unit is complete. The CPU generates the second control signal in response to receipt of the first control signal, and generates a third control signal to clear the data connecting circuit in response to receipt of the transmission state signal.

An integrated data communication card installed in an ISA bus slot of a multimedia personal computer capable of performing communication and overlay functions and of reducing load for the computer. Such an integrated data communication card comprises a network connector connected to a network terminal for enabling transmission of data to and from a communication network; a system connector connected to a central processing unit of the computer for enabling data transmission to and from the computer; a data processor communicable with a storage device and the network connector, for processing data in an asynchronous transfer mode received from or transmitted to the network in response to a system control signal or a first control signal; a decoder for decoding the data determined not to be processed through the network in response to the system control signal, and for decoding data determined to represent compressed motion picture data in response to a second control signal; an overlay processor for generating image overlays from the decoded data for display on a video monitor; and a transmission controller for generating the first and second control signals under control of the system control signal.
