We all have at least one technologically challenged relative. We will e-mail photographs or submit them on a private Web web page for Memory Wave some of our beloved ones, but there are others who need nothing to do with a pc, not to mention the Internet. The perfect gadget for sharing images with the computerless is the digital picture frame. This can be a gadget about the dimensions and shape of an strange image frame. It incorporates an LCD display screen, which displays multiple photos in a slideshow format, and it connects to the Web via telephone line to download new pictures and data to display on the display screen. The frames are fairly similar in development, although they do provide some totally different features. On this edition of HowStuffWorks, we’ll take a look at the Ceiva Digital Picture Receiver. Earlier than we get into exactly how it really works, let’s see what it does. The concept is that a person who does have a pc, a digital digicam and pc expertise buys the frame, units up the account and passes it on.

As soon as the account is arrange, you (the particular person with the computer) add pictures to the Ceiva Internet site. Each night time, the digital image body (in the computerless particular person’s home) uses the telephone line to hook up with the Ceiva servers and download any new photos. It’s also possible to management all of the body’s settings via the online site. It has most of the same elements as the computer in your desktop, however they’re so much simpler in the frame because they solely should perform a single process. The central processing unit (CPU) within the Ceiva digital picture frame is much like the type utilized in small, electronic handheld games. Essentially the most processor-intensive task performed by this CPU is downloading photos from the net site. The rest of the time, it does not break a sweat. It also has some Flash memory, which is where the photographs, settings and some of the working software program reside.

Both varieties of Memory Wave Routine are persistent -- no data is misplaced if the unit is unplugged. The frame has a 33.6-Kbps modem, which it uses to connect with the Web and download the brand new images you post. The display is a 640x480-pixel, passive-matrix liquid crystal show (LCD) with a viewing area of about 5 by 7 inches (13 by 18 cm). This sort of display is skinny enough that the digital frame is not a lot thicker than an peculiar picture frame. The pictures are displayed in 12-bit color, which implies that approximately 4,a hundred completely different colours may be offered on the display. The only user-operated controls on the frame are a black button, which adjusts the brightness of the show, and Memory Wave Routine a white button that turns the frame on when the user first plugs it in and can also be used to manually dial in. The Ceiva body uses an embedded operating system called PSOS.

This working system is designed for gadgets like PDAs, electrical-testing gear and set-prime packing containers. Let’s take a look at how the Ceiva body works. If the consumer presses and Memory Wave holds the white button on the back of the body, it dials up and connects to the Internet. The $50-per-12 months fee for the Ceiva service contains access to the Web by the use of a neighborhood telephone number. The connection to the Internet is used only to obtain the new photos and settings to the body. There isn’t any interactivity, no Net access and no e-mail. The device is designed to behave like a picture body, not a pc. As soon as logged on, the frame compares the photographs already on the frame to the ones ready to be sent, downloading any new ones. It additionally downloads any new settings. When it is completed downloading, the frame hangs up the cellphone line and begins displaying the brand new photos one after another.
