  • 1. TITLEDISTRIBUTED EMBEDDED SYSTEM AND ITS APLLICATIONS PAPER PRESENTED BY: VIVEK R. CHAMORSHIKAR
  • 2. POINTS TO PRESENT Introduction to embedded system Digital camera Image resolution Method of image Capature Format Mp3 Audio quality Bit rate Conclusion
  • 3. INTRODUCTION TO EMBEDDED SYSTEM1. PURPOSE OF EMBEDDED SYSTEM2. WHAT IS EMBEDDED SYSTEM?3. APPLICATION SPREAD IN VARIOUS FIELD4. CHARACTERISTICS OF EMBEDDED SYSTEM
  • 4. DIGITAL CAMERA1. WHAT IS DIGITAL CAMERA2. COMPACT DIGITAL CAMERA3. IMAGE RESOLUTION4. METHOD OF IMAGE CAPTURE5. FORMATS
  • 5. WHAT IS DIGITAL CAMERA? A digital camera (or digicam for short) is a camera that takes video or still photographs, or both, digitally by recording images via an electronic image sensor. Digital cameras can do things film cameras cannot: displaying images on a screen immediately after they are recorded, storing thousands of images on a single small memory device, recording video with sound, and deleting images to free storage space.
  • 6. IMAGE RESOLUTION AND CAPATURE ROLE OF PIXEL SENSORS CCD AND CMOS CHIPS METHOD OF IMAGE CAPATURE THREE METHODS FORMATS
  • 7. MP3  WHAT IS MP3? OPERATIONS IN MP3 BIT RATE AUDIO QUALITY 
  • 8. INTRODUCTION TO MP3 Digital audio player, more commonly referred to as an MP3player, is a consumer electronics device that stores, organizes andplays audio files. Some DAPs are also referred to as portable mediaplayers as they have image-viewing and/or video-playing support. MP3players are now regularly built into mobile phones, making them themost common form of digital audio player. The term MP3 is actually a reference shortened from theofficial Moving Picture Experts Group-1 Audio Layer 3nomenclature for this lossy digital audio encoding format.
  • 9.  OPERATIONS IN MP3 INCLUDE FOLLOWING FLASH MEMORY HARD DISK DRIVE EMBEDDED PROCESSOR
  • 10. AUDIO QUALITY AND BIT RATE BIT RATE FACTOR AFFECTING AUDIO QUALITY CBR AND VBR STANDARD BIT RATE
  • 11. CONCLUSION Thus embedded system contain programmed instructtion running via processor chips.they preform controll, protection and monitoring task. In board term embedded system are programmable device or system which are generaly used to controll or monitor things.
