We all have at least one technologically challenged relative. We are able to e-mail pictures or put up them on a personal Net web page for some of our cherished ones, however there are others who want nothing to do with a pc, not to mention the Internet. The perfect gadget for sharing photographs with the computerless is the digital picture body. This is a device about the size and shape of an unusual picture frame. It incorporates an LCD display, which displays multiple images in a slideshow format, and Memory Wave it connects to the Internet via telephone line to obtain new footage and data to display on the display. The frames are pretty related in development, though they do provide some totally different features. In this edition of HowStuffWorks, Memory Wave Method we'll take a look at the Ceiva Digital Photograph Receiver. Earlier than we get into precisely how it works, let's see what it does. The concept is that a one who does have a pc, a digital camera and pc expertise buys the body, units up the account and passes it on.
Once the account is set up, you (the particular person with the computer) upload photographs to the Ceiva Internet site. Every night time, the digital picture frame (in the computerless particular person's home) makes use of the telephone line to connect with the Ceiva servers and obtain any new pictures. You can even management all of the frame's settings by way of the online site. It has most of the same parts as the computer on your desktop, however they're quite a bit less complicated within the frame as a result of they only must perform a single activity. The central processing unit (CPU) within the Ceiva digital picture body is much like the type used in small, digital handheld video games. The most processor-intensive process carried out by this CPU is downloading photos from the online site. The remainder of the time, it doesn't break a sweat. It also has some Flash Memory Wave Method, which is the place the images, settings and a few of the working software stay.

Both sorts of memory are persistent -- no knowledge is lost if the unit is unplugged. The body has a 33.6-Kbps modem, which it makes use of to connect to the Internet and download the new images you put up. The show is a 640x480-pixel, passive-matrix liquid crystal display (LCD) with a viewing area of about 5 by 7 inches (thirteen by 18 cm). Any such show is thin enough that the digital frame isn't a lot thicker than an abnormal picture frame. The images are displayed in 12-bit shade, which signifies that roughly 4,100 totally different colours might be offered on the display. The only consumer-operated controls on the body are a black button, which adjusts the brightness of the display, and a white button that turns the body on when the person first plugs it in and can also be used to manually dial in. The Ceiva body uses an embedded working system known as PSOS.
This operating system is designed for devices like PDAs, Memory Wave electrical-testing equipment and set-prime containers. Let's take a look at how the Ceiva frame works. If the consumer presses and holds the white button on the again of the frame, it dials up and connects to the Internet. The $50-per-12 months payment for the Ceiva service includes access to the Web by the use of an area telephone number. The connection to the Internet is used solely to download the brand new photographs and settings to the frame. There is no such thing as a interactivity, no Internet access and no e-mail. The system is designed to behave like an image body, not a pc. Once logged on, the body compares the pictures already on the frame to the ones waiting to be sent, downloading any new ones. It additionally downloads any new settings. When it is finished downloading, the frame hangs up the phone line and begins displaying the brand new pictures one after another.
