摘要： A method of manufacturing a display device includes forming a buffer layer on a top surface of a substrate, forming an amorphous silicon layer on a top surface of the buffer layer, and forming a polysilicon layer by irradiating the amorphous silicon layer with a laser beam. A plurality of first protrusions are formed on the top surface of the polysilicon layer, and a plurality of second protrusions are formed on a surface of the buffer layer by transferring the shape of the polysilicon layer to the buffer layer. A gate insulator on the buffer layer is then formed in the shape of bumps of the second protrusions.

摘要： Provided is a method and apparatus for encoding and decoding an enhancement layer to reduce quantization error in a G.711 codec. Exponent indices of additional mantissa information of each sample are calculated based upon exponent information of each sample in a frame. A process of allocating 1 bit to each sample with a current exponent index is repeated, the exponent index starting from the maximum value while decreasing by 1 at every repetition until the total number of bits allocated to the samples is equal to the total number of available bits in the frame. And the most significant bits, as many as the number of bits allocated to each sample, are extracted from the additional mantissa information of each sample in the frame.

摘要： A direct memory access controller (DMAC) for improving data transmission efficiency in multi-media over internet protocol (MMoIP) and a method therefor are provided. The DMAC requests and obtains a bus control right by determining that a DMA request signal is generated not only when a DMA request signal of a module for processing data in MMoIP is received but also when an operation of a timer operating during a predetermined period set considering periodicity of data in MMoIP is completed. Thus, the time taken to request a bus control right in a conventional DMAC can be reduced, thereby improving data transmission efficiency in MMoIP.

摘要： A method for selecting a relay mode depending on channel status of relay links in a multihop relay broadband wireless communication system and a Relay Station (RS) apparatus for supporting the method. When signals are received from a Base Station (BS) and a Mobile Station (MS), channel status values (e.g., eigenvalue, mutual information, and probability error) of relay links (BS-RS link and RS-MS link) are estimated using the received signals. The estimated channel status values are compared with a preset reference value. According to a result of the comparison, the relay mode for relaying the received signals is selected. Accordingly, the reliability of the relayed signal can be enhanced and the capacity of the signal link can be increased.
