Question

What is the difference between DVD, VCD, VCR, there is always a variety of definitions that confuse me.?

Answer 1

Hi,



These are three different formats for storing media, especially video.



1. VCR- Video Cassette Recorder: VCR is well on it's way to extinction. Although there is still a lot of vcr tapes in people's libraries, with the advent of high-definition dvd, they are a thing of the past. They could be used to record movies onto for repeated playback. The negative aspect was that just as an audio cassette tape would wear out from the rewinding so will the vcr tape.



2. VCD- video compact disc: This is basically a compact disc that is used to store audio/music or video. It has limited storage of around 700 megabytes or about 74 minutes of audio.



3. DVD- digital video disc or digital versatile disc: The dvd is currently the standard for storage of media. A basic dvd will hold about 4.7 gigabytes of media/ or about 7 times as much as a CD. There are also dual layered dvd's that are 8.4 gigabytes in size. High Definition is a technology that has been developed through the advent of the DVD.



To try and answer your question if I understand what you are asking...first came along VCR, second came VCD or CD, third came DVD, and currently there is the format of HD DVD as well as others.

Answer 2

VCR - VideoCassette Recorder - this device provides the ability to record and play back video that has been stored on a magnetic tape cartridge. Few of these are sold these days. In the beginning, there were two types of VCR's - VHS and Sony's Beta. Nearly all companies began selling VCRs that used the VHS cartridge format, so Beta's were phased out.



DVD - Digital Video Disk or Digital Versatile Disk - this device is more frequently a play only device, though DVD recorders are available, but at a higher price. The format is a disk that visually appears to be similar in to Compact Disk (CD). There are a variety of formats available here, including two incompatible formats for recording High Definition video.

VCD - Video Compact Disk - is a format different from those used for DVDs. The audio is stored differently, and the compression on the video is different.



Many DVDs can play VCDs. VCDs are nearly always created from PC software.
