ABTRACTS : Distributed coding enables higher compression rate of a video signal. Till date we used a complex encoder and simple decoder. The advantage of having a simpler encoder and a complex decoder is increase in the compression ratio. Here in this project an optimized distributed video coding scheme is proposed which is a combination of an intraframe encoder and an interframe decoder. The distributed video coding scheme is based on punctured turbo codes. Turbo codes are punctured to generate scalable compressed video bit streams. An improved turbo coding performance leads to an overall performance improvement. Zero motion skip encoding strategy is used so that the decoder is made aware of these zero motion blocks such that encoding of these blocks can be avoided. The decoder may use this to improve the performance.
KEYWORDS :Distributed video coding, turbo codes, zero motion skip encoder strategy.

ABSTRACT: wireless data acquisition, data logging and supervisory control are the basic building blocks of plant automation. In this paper plant consisting of multiple boilers where multiple process variables of the boilers need to be acquired from the field is considered and analysed. The data of the process variables needs to be logged in a database for further analysis and supervisory control. A Lab VIEW based wireless data logging and supervisory control program simulates the process and the generated data are logged in to the database with proper indication about the status of the process variable. This gives the overview of modern day data acquisition system, data loggers and supervisory control techniques. Wireless data acquisition and data logging program is used to log the measurements of different process variable data in a database. The database also shows the status of the process variable as normal or abnormal.
