Image Distribution

Now that our images are generated, we have to transfer them from the location where they are generated to the location where they can be displayed, processed , and analyzed . In the section Frame Grabbing we talk about "the other end of the camera cable"; that means principles regarding capturing camera signals, digital as well as analog. To cover the digital part, we discuss some important details about bus systems and protocols . Naturally, it is not possible to cover all of them, so we focus on the more important ones.

The second part of this chapter deals with compression techniques in general first, and then with some image and video standards , which usually make use of compression. Finally, we learn about a medical standard covering this field, DICOM (Digital Imaging and Communications in Medicine) .
