Of the many available video interfaces, Digital Visual Interface, or DVI, is a video display interface which was developed and maintained by the Digital Display Working Group (DDWG). Usually, DVI is related to, and talked about, in association with computers, but it is also used in other consumer electronics (T.V. sets, video game consoles, and DVD players). It is used to connect a source, whose output is the video that you want to see, to a display device such as a monitor or TV. DVI is designed to transmit uncompressed digital video signals and is configurable with three modes, namely DVI-A (analog only), DVI-D (digital only), and DVI-I (digital and analog). It is also compatible with the Video Graphics Array (VGA) interface, making it more widely accepted over rival digital display standards.
Video capturing, in simple terms, involves the conversion of an analog video signal to a digital video stream, which is present in the form of computer files and can be stored in memory. This concept originated with the hardware ‘keylogger’, which is an electronic device used to capture and record a computer user’s keystrokes, including passwords.
Naturally, since a variety of protocols and interfaces are available for transfer and display of video files, a capture device has to be particular to only one type of interface. Current video capture devices are available in the form of cards (Printed Circuit Boards) which when connected to any video source and a computer, will record the captured source to a disc/directory (through accompanying software). Several types are available, from companies such as Datapath Limited. Varieties include high-definition support, VGA compatibility, and HDMI compatibility.
Keelog’s new dvi capture technology does away with the tedious requirement of specialized software. It is hidden inside a standard-looking video cable, and is connected between the video output socket of a CPU and the TV or monitor. It also has a USB cable, which can be connected to any free USB socket in order to power the device. The VideoGhost has an in-built microprocessor and an FPGA chip, which enables it to easily convert captured video signals into JPEG images. These images are then stored onto its internal 2 gigabytes of flash memory, thus eliminating the need for an external disc drive.
To view the stored JPEG images, the device is connected to any computer via USB. They can then be viewed using a personalized USB key, which comes with every package, thus making the entire process secure. A built-in JPEG encoder is also present.
Some of the VideoGhost’s other prominent features include:
* Built-in time-stamping module
* Compactness and discretion
* Zero configuration requirement
* Undetectable to security scanners
* Enhanced versions available (VideoGhost Pro & VideoGhost Max)
The VideoGhost is available in multiple colors (white, grey, and black), at an appreciable starting price of £86.99. It finds applications in:
* Capturing crucial images from slide shows, presentations, etc.
* Protectively monitoring children’s online activities
* Monitoring the productivity of a company’s employees
* Monitoring activity from surveillance cameras

Vision Boards Examples – Inspire Yourself
If you have heard the phrase vision board before but never really knew what it was, it is a tool that is so beneficial in people’s lives. It is a simple and easy concept that has huge results. It literally is a poster board on which you paste images or quotes that you have collected from magazines or newspapers over the years. You want these images to be inspirational and of things you like. The idea behind this is that you become what you want to be through seeing those images daily. There are many vision boards examples because every person is different.
One of the best vision boards examples are for people who are planning a vacation. Even if you cannot go for years, it still is fun to plan it. Say for instance you want to travel Europe. All you would do is collect photos and the different places you want to visit and the different things you want to see over there and put them on your board. Anytime you are feeling down, all you have to do is look at your board an you will become happy. You just want to make your board full of images that will inspire you to go to a better place in your mind.
The great thing about vision boards examples is that there is no such thing as a wrong board. You do not even have to use poster board if you do not want to do so. You can use anything. You can take a blank diary booklet and turn that into your vision board. Each page can be a new theme that you can use for inspiration. You even can use vision boards to help advance your career. You just go through magazines and newspapers and find images or quotes of what you want out of your career. Put them all together and you have your vision board.
Another great thing about the many different vision board examples is that they can have themes to them or they can just be a collection of different things you want out of life. Whether this is your health or a family, just put the images all over the board. There does not have to be a rhyme or reason to it because life has no rhyme or reason. You just want to make sure the images really speak to you.
