Abstract: A transmission apparatus, a reception apparatus, a transmission system which combines these, and a transmission and reception method thereof are provided. The transmission apparatus includes a first transmission unit which transmits data via a channel in a first band, a second transmission unit which transmits data via a channel in a second band, and a transmission control unit which controls the first transmission unit to stop transmitting the data via the channel in the first band if interference is sensed in the channel in the first band. Accordingly, data can be provided without data interruption in a wireless environment where there is interference.

Abstract: A neutral beam-assisted atomic layer chemical vapor deposition (ALCVD) apparatus is provided for uniformly depositing an oxide layer filling a planarization layer or a trench to increase uniformity and density of the oxide layer using neutral beams generated by a neutral beam generator without a seam or void occurring in an atomic layer deposition (ALD) or ALD-like chemical vapor deposition (CVD) process, thereby solving problems on the void or seam and low density occurring when a high-density planarization layer or a shallow trench having a width of 65 nm or less is formed, and improving a next generation oxide layer isolation process.

Abstract: Compression of blocks of digital data is optimized by optimally selecting between frame and field format compression on a block-by-block basis. Specifically, a set of pixel data presented in a field format is compressed to provide a field compressed image signal. The set of pixel data is also presented in a frame format to provide a frame compressed image signal. The field and the frame compressed image signals are quantified; and the compressed image signal having the lesser amount of bits is then selected. The selection effectively improves the quality of the transmitted signal and reduces the structural complexity and manufacturing cost of the image signal encoding apparatus.
