Getting to know more about Video Technology

Do you want to know something about video technology? As what we all know, video is the capturing, storing, transmitting, processing of moving images electronically. You have probably seen one, but have you ever think of how this technology was created? The first video technology was invented for a certain tube television system. After the great efforts by the experts, the video technology brought the television sets and computer monitors into our world. Few years later the computers were improved. At this time, it can flash and process video clips and streaming media. Because of the necessity experts tried to create an additional feature of the video technology. At this time high speed video was created and storage capacity was expanded up until memory cards were introduced.

The word video was derived from the Latin word “to see”, which can cater for different formats for moving pictures. These are the DVD, MPEG-4, and the analog video format which includes the VHS and the Betamax. The quality of the captured video may depend on the type of storage and how it is captured. Just like, for example, if you have hand tremors, and you are capturing a moving object through a video recorder. In this case, the outcome of your recorded video will have less quality. This may be observed from a blurring and scratchy effect on the screen. On the other hand, storage devices contribute a lot to the video quality because if you have a small storage capacity then, the total video information cannot fit in. Just like what you observed in the internet. If you are downloading a high definition video you can see that the memory load is higher than the low definition videos.

Because of our highly improved gadgets, we can now capture, store, transmit, and process videos through the use of different kinds of devices. In capturing video, we can use the camcorder, computer cameras, and mobile phone cameras. On the other hand, storing video can be molded into the different format so as it can be stored in memory cards, compact disk, and computer hard drives. There are different ways in transmitting videos. This is done by transferring data from one device to another. This is through the aid of Bluetooth, direct USB connection, infrared, and via the internet.

Now that we know about the history and how video technology works let's dig deeper into the different video formats which are commonly used today and few years ago. Let us start with the DVD format. The digital versatile disc or the digital videodisc is what we have commonly known as the DVD. This is a media format that uses an optical disc. This is mainly used not only for video storage but also for data storage. The DVD was invented around the year 1995. There are two types of DVD. These are the digital videodisc recordable (DVD-R) and the digital videodisc-rewritable (DVD-RW). The DVD-R is a storage format where video and data can only be stored once. While the DVD-RW, allow you to store and edit the saved video and data. DVDs can store a high loaded video. The storage capacity of the disc may depend on its number of sides, layers, and its diameter. There are different devices that can play DVD videos... These players are composed of lasers, which allow them to read through the disc.

Another type of video format is the MPEG-4... This format is better that the DVD because of its numerous capabilities... MPEG-4 is capable of storing and processing not only video but also audio data. Other feature of this audio format is that it can be used for distribution of CDs, voice, and video broadcast applications. What are the advantages of using an MPEG-4 format for video recording, processing and storing? It has a well developed coding effectiveness, can program a merged media data such as the video, audio, and even speech). The special feature of the MPEG-4 is that it has error resilience. It means if any error occurs the video can still function. This is important for videos, which require a good accuracy for viewing.

The next type of video format is the analog type which includes the VHS and the Betamax. Today these two formats are considered to be obsolete. What are the good things with regards to the use of analog video format? First is that it can record video and allows you to edit any scene. Next is that it can display video in an average standard. The disadvantage of using the analog format is that there is a higher tendency of altering the video quality. Another is that it is time consuming when operating with its player.
