It is an EEPROM type memory (Electronically Erasable and Programmable Read Only Memory). It was created in 1984 by Fujio Masuoka. There are many versions of it: some have the shape of a pen, a bar, camera cards, etc. It is quick and silent, and it is easy to carry. It has a storing capability that is much higher than its predecessor, the floppy disc. |

|
DVD |
It stands for Digital Video Disc or Digital Versatile Disc. It replaced the Beta technology in recording and distributing video material. Its recording process is based on the use of laser instead of electromagnetism. This provides more quality in both audio and video. |
|
|
retinal persistence |
It is the effect in the eye’s retina that makes the images perceived by the eye be recorded for a very small fraction of time, like a tenth of a second. When the eye is exposed to a succession of fixed images, the illusion of movement gives life to the magic of cinema. It was discovered by the Belgian Joseph Plateau.

FPS |
It stands for Frames per second. It is the amount of frames that are shown on a video in a period of one second. |
|
|
PAL |
It stands for Phase Alternating Line which consists on the using of 25 frames per second. It is used in Europe, Asia, and some countries in America. |

|
NTSC |
It stands for National Television System Committee. It consists on using 30 frames per second to create video, including an aspect ratio of 4:3 and an optimum handling of sound. |
|
|
SECAM |
(Séquentiel Couleur à Mémoire): it is similar to PAL, but it is less known. It was created in France, so it is more used in Europe, and it has an optimum handling of color. |

|
|
HDTV |
(High Definition Television): it works with three resolutions: 720p, 1080i and 1080p; it has the ability to be converted as needed in order to commute among them. There are two possible values for the handling of the different resolutions: “p” or “i”. |
|
|
blu-ray |
It refers to the technology based on a blue beam that allows the recording of different layers of a DVD, especially designed for high density recording. It may contain from 1 to 4 layers, and each one has a capacity of 25GB. It handles HD information (1080p/60), differently from the DVD which only handles 480p or 576p. |
|
|
HD-DVD |
It stands for High Definition Digital Video Disk. It was supported by Toshiba as a better alternative to DVD since it allowed a storing of 15 GB in each one of its layers. |
|
|
codec |
It means coder-decoder. It is software that consists on an algorithm to compress and decompress video in real time. Its use doesn’t interfere with the playing speed. There are also codecs for audio files. |
|
|
AVI |
(Audio Video Interleave) It is one of the standard formats to store digital video in different platforms. |
|
|
DivX |
It is a codec that can be used in Windows and MacOs platforms to create MPEG-4 standards. |
|
|
XviD |
It is a compression algorithm, developed by free programmers. It does not represent any loss of information. A complete movie can weight only 700MB instead of several GB. |
|
|
MPEG |
(Moving Picture Experts Group) It is a format that is considered standard to compress digital video. The extensions of the files under this format are .MPG or .MPEG. As a characteristic, they can also integrate different kinds of codecs: MPEG-1 (CD quality), MPEG-2 (DVD quality), MPEG-3 (focused on taking more advantage of the MP3 audio), and MPEG-4 (to publish it on the web). |
|
|
MOV |
(Movie) It uses Apple’s own codec, which handles the color palette of this platform optimally. This type of files may also have the .QT extension, which is for the Quick Time app. |
|
|
WMV |
(Windows Media Video) This format was designed by Microsoft. It is based on the MPEG-4 codec to compress the video. It can be found with the extension .ASF. It is compatible with Windows 7 or beyond. Just like in MOV, it allows streaming and it is fairly good for being published on Internet. |
|
|
RM |
It is the format of Real Networks for video files. It is based on its own codec to compress the audio, and it has an extension .RM and .RAM. It is necessary to have the Real Player app to work. It has a good aspect ratio with weight, quality and size for a video to be publishable on Internet since it allows streaming. |
|
|
FLV |
(Flash video) This format is based on the Sorenson Spark and On2 VP6 codecs. Both allow a high visual quality no matter if the user has a high downloading speed in his devices. Their extension is .FLV which can be reproduced from different local programs such as MPlayer, VLC media player, Riva, Xine, etc. |
|
|
VOB |
(Video Object) It is the format that contains video, audio and subtitles. Its extension is .VOB and it is normally used in the distribution of DVD, being kept in order inside the folder of Video_Ts.

It often happens that we record a video with our phone at a family reunion, and we can’t share it because when we try to download it on our computer, it doesn’t support the format in which it was recorded. If we want to see it then we need to download a special program in order to recognize the format. |
