The Reed Solomon Code(RS Code) has been widely employed in digital audiolvidio equipment such as CD, DAT, and Professional video recorders owing to its excellent capability for correcting burst errors and relatively easy implementationWe proposed an architecture of an error correction circuit suitable for high-rate data decoding of the Reed-Solomon W e .The circuit has encoder and decoder functions by 2 symbol random error correction as well as 4 symbol erasure correction And 23MByteis rate of data decodina i s sufficient for compressed vidio signals of high-definition as well as those Of stand-definition TVS

As we secure sufficient space to distribute power generation equipment of solar energy, there will be no shaded area, but for the limited space, we can find temporaryshaded area surely for a few moments or a few hours .For the fixed type which are used to most roof solar power plant, side beam is projected for certain period of time before and after sunset, it would be affected to electric generation efficiency, so we researched to solve this phenomena using concave and convex mirror. For basic principle, when module is positioned at shaded area and time, it can deliver to be spread toward module to be accumulatedsunshine with concave mirror and reflected with convex mirror. For net energy which is obtained from sunlight, it produced 223W/day and it produced 207W/dayusing reflect mirror, we can get result which we can get similar amount of power energy only with reflect mirror.It shows that the production by direct light has increase of 8% more than production by reflected light.
