If we take a look at the way the home video technology has progressed over the years, we will be amazed at the extent to which it has changed in such a short period. The VHS (Video Home System) technology brought motion pictures into our living rooms and bedrooms. It was followed by the CDs, VCDs, and SVCDs that were more expensive, but provided excellent quality and utility. This was followed by the DVDs and DVD players that took the market by storm and became the most preferred mode for recording and viewing of movies. Most recently however, the latest technology that has joined the race is HD DVD (High Definition Digital Video Disc), that has much higher storage capacity and enhanced quality attributes.Do you want to learn more?

Correspondingly, there has been a similar evolution in the digital data storage and handling industry. This journey started with the floppy, followed by the CDs, the laser discs, the DVDs, and then the HD DVDs. Data storage and handling are a field by itself and has grown at a phenomenal rate.
The first step towards home theater was the Video Home System (VHS), introduced in September 1976. It was developed by JVC along with some licensing agreements with Sony. The VHS is a recording and playing standard for the Video Cassette Recorders, well known all over the world as the VCRs. The VHS could record and play back all the analog television signals in existence at the time it was devised. By today’s standards, it is one of the poorest quality video formats. The video recording cassette being big, its recording camera was also big and cumbersome. This led to problems of handling and transportation.
The VHS-C is the Video Home System-Compact, which is the same in quality as compared to the standard VHS, that is, half inch size and 240 lines of resolution. But as the name suggests, it is more compact and allows for the video camera to be lighter, smaller, and more convenient. The VHS-C has to be placed in a regular VHS sized case to enable it to be played on the VHS player. The 8mm VHS tapes are smaller in size and are very convenient to use in recording cameras, but are not compatible with the regular VCRs and cannot be played directly on the VCRs.
CD and VCD
The Compact Disc (CD) is an optical disc that is read by a laser. It is a polycarbonate disc designed to store data, music and video formats. These were played on CD players and were of the CD-R and CD-RW type in particular. It was designed by Philips and Sony in 1988. In 1993, Matsushita, Philips, Sony, and JVC introduced a CD format that could hold a full- motion video. It was called the Video CD (VCD) or the compact disc digital video and had a standard digital format for storing video on a compact disc. These VCDs could be played on VCD players and computers. A video CD can hold VHS-quality video of 74 minutes and has a CD-quality sound using MPEG-1 compression. The VCDs were very popular in the Asian countries due to their affordability factor, but did not get much popularity in the U.S. or Europe.
