Use of computers for audio- video CDs

Use of computers for audio- video CDs  OVERVIEW

The 21st century has seen unprecedented developments in the field of electronics. This has had a lot of positive bearing for the media and enhancement of communication. The sound tracks were earlier recorded in audio cassettes and the videos were recorded in video cassettes. We had to use a audio player or a video player to play back these tracks. However, the use of computers has opened up a different possibility before us. The audio and video tracks can be stored in computers as files, copied on to CDs and played back in other computers. The storing capacity of the CDs is much larger compared to the cassettes. The quality of recording is also better in CDs. CDs are easy to carry, store and use. With the introuduction of digital cameras, we have the facility to create our own video programmes and use them in the district for teacher education purposes.
