HIGH LEVEL CONTROL
SIGNAL PROCESSING
REAL TIME APPLICATION
Introduction

10. Signal Processing
 Most signal processing application has real time
requirements.
 Examples are digital filtering, video and voice
compression/decompression , radar signal system
etc.

15. Real Time Application
 Real Time Databases
 Contain data objects called image objects which represent real
world object
 Attributes of an image objects are those that of the real world
objects they represent.
 The values of these attributes are updated regularly because
the real time data are perishable
 Multi media application
 It can process, store, transmit and display any number of
audio streams, video streams, images, graphics and text.
 Video stream encodes video and audio stream encodes voice,
sound or music
