    Abstract: A broadband internal antenna using double electromagnetic coupling is disclosed. The disclosed antenna may include: a first conducting member electrically connected to a feeding point; a second conducting member placed at a designated distance from at least a portion of the first conducting member so as to allow a first electromagnetic coupling with at least a portion of the first conducting member, and remaining in a floating state without being coupled to a ground and the feeding point; a third conducting member placed at a designated distance from the second conducting member so as to allow a second electromagnetic coupling with the second conducting member, and electrically connected to the ground; and a fourth conducting member extending from the third conducting member, for radiating RF signals. The disclosed antenna has the advantage of providing broadband characteristics within a limited size.

    Abstract: An MPEG-4 encoder utilizing an H.263 multimedia chip. The MPEG-4 encoder includes a DC (Direct Current) predictor for predicting a DC component of the image frame encoded by an H.263 standard upon receiving a prescribed MPEG-4 quantization value, and an MPEG-4 reconstruction image memory for converting the H.263 reconstruction image into an MPEG-4 reconstruction image, and storing the MPEG-4 reconstruction image. The MPEG-4 encoder removes spatial redundancy from source image data entered in frame units using a prescribed H.263 quantization value, predicts a DC component of an image frame having no spatial redundancy using a prescribed MPEG-4 quantization value, performs a VLC (Variable Length Coding) process on the image frame using the predicted DC component, and outputs the VLC-processed image frame in the form of an MPEG-4 bit stream. The MPEG-4 encoder reconstructs the image frame having no spatial redundancy, stores the reconstructed image frame, converts the reconstructed image frame into an MPEG-4 frame, stores the MPEG-4 frame, compares the stored image frame with a newly-entered next frame, and removes temporal redundancy according to a result of the comparison.

    Abstract: An apparatus and a method for transmitting and receiving moving picture data, which can stream the moving picture through the near narrowband communication network in real time by using a portable terminal having a near field communication module like a Bluetooth module. The apparatus transmits some of audio visual data stored in the form of a file which is prescribed by Moving Picture Experts Group to the portable terminal connected to the near field communication network to allow the portable terminal to replay the audio visual data. Then, the apparatus divides the residual data into files with a desired size and transmits the files to the portable terminal, so the portable terminal can simultaneously receive and replay the moving picture.

    Abstract: Disclosed herein is a method for forming an isolation film of a semiconductor memory device. According to the disclosure, in a pre-treatment cleaning process performed before a tunnel oxide film is formed, a SC-1 cleaning process is performed at a temperature ranging from 60° C. to 70° C. Therefore, oxide films in a cell region and a peripheral region are recessed even in the SC-1 cleaning process as well as a DHF cleaning process. A DHF cleaning time can be thus reduced. Accordingly, the method can minimize loss of a silicon substrate by DHF and can thus control the depth of a moat.

    Abstract: Disclosed is a method of manufacturing a flash memory device. In a flash memory device using a SA-STI scheme, a trench for isolation is buried with oxide. A field oxide film is then formed by means of a polishing process. Next, field oxide films of a cell region and a low-voltage transistor region are selectively etched by a given thickness. As EFH values of the cell region, the low-voltage transistor region and the high-voltage transistor region become same or similar, it is possible to secure stability of a subsequent process.
