    Abstract: PURPOSE: A system for compressing a still image of a digital camcorder and a method for compressing a still image are provided to remove image drop and image flickering from a reproduced still image. CONSTITUTION: A charge coupled device(CCD)(204) receives an image inputted from a lens and has a lens shutter function. A frame memory(208) divides the data of the CCD into odd line data and even line data for storing the divided data, and stores an image synthesizing signal obtained by synthesizing the neighboring odd line data and the even line data. A frequency change module(214) changes frequency of the image synthesizing signal. A luma/chromer module(216) divides the image synthesizing signal into Y and CbCr signals to transmit the Y and CbCr signals to the frame memory. A joint photographic experts group(JPEG) codec(210) encodes and decodes the data stored in the frame memory.

    Abstract: PURPOSE: A method for transmitting and receiving data between a BSC(Base Station Controller) and base stations in a mobile communication system is provided to efficiently transmit and receive the data by connecting the BSC to the base stations, bidirectionally transmitting, and receiving the data. CONSTITUTION: A BSC(100) and a plurality of base stations(11,13,15,17) are connected by a ring structure. Data are transmitted and received between the BSC(100) and the base stations(11,13,15,17) in the first and second directions. The data transmitted and received in the first direction are processed as valid data in a normal state. If link fault is generated while the data are transmitted and received in the first direction, the data transmitted and received in the second direction are processed as valid data.

CONSTITUTION: A moving image compression system includes the first local memory(118) receiving video data from an external device and storing the video data, a motion estimation processor(112,114,116) for reading the video data from the first local memory to estimate a motion of the video data and carrying out motion compensation to generate a differential signal, the second local memory(122) for storing the differential signal, and a DCT(Discrete Cosine Transform)/IDCT(Inverse Discrete Cosine Transform) unit(126) for receiving the differential signal and discrete-cosine-transforming the differential signal to encode the video signal. The system further includes a quantization/inverse quantization unit(128) for quantizing the discrete-cosine-transformed data, the third local memory(130) for receiving the quantized data and storing the encoded video data, an adder(124) for adding up output signals of the second local memory and DCT/IDCT unit and outputting decoded video data to the first local memory, and a variable length decoder(134) for receiving the video data from the third local memory to statistically reducing the data.
