This paper implemented The LED illuminance control IP based on 8bit RISC Processor. 8bit RISC Processor designed hardware interrupts, an interface for serial communications, a timer system with compare-capture-reload resources and a watchdog timer. LED Array consists of Red, Green, Blue, White and Warm White. The illuminance control IP is used to LED Board control with 8bit data.

This paper presents compression rate improvement for SPIHT algorithm though redundancy bit removing. Proposed SPIHT algorithm uses a method to select of optimized threshold from feature of wavelet transform coefficients and removes sign bit if coefficient of LL area. Experimental results show that the proposed algorithm achieves more improvement bit rate and more fast progressive transmission with low bit rate.

We proposed a new bit-rate control algorithm to improve MPEG-2 video software encoder. Bit-rate Control plays an improtant role in picture quality of MPEG-2 encoder. To achieve better encoding performance such as controlling picture quality and using bity properly, we proposed a MPEG-2 bit-rate control algorithm using linear average Step-Size. Using a benchmark Program, we compared our algorithm with MPEG-2 Test Model 5. Our proposed algorithm showed better Bit-Rate Control with respect to used bits, picture quality.

The simplest bit error detection scheme is to append a parity bit to the end of a bit sequence. In this paper an error correction technique with the use of a parity bit is proposed, and the performance of the proposed system is analyzed. The error probability of the proposed system is compared with the output of computer simulation of the proposed system. It is also compared with the error probability of error at BPSK system, and the signal-to-noise ratio gain is showed.

In this paper, we analyses transmission performance of communication security(COMSEC) bit synchronization information over the single channel ground and airborne radion system in variable message format system. Experimental results demonstrate the robust characteristics of the COMSEC bit synchronization information in 10-1 $\~$ 10-5 of bit error channel and the relationship of time duration of bit synchronization and probability of synchronization detection.
