The process of converting a media file or object from one format to another. Transcoding is often used to convert video formats (i.e., Beta to VHS, VHS to QuickTime, QuickTime to MPEG). But it is also used to fit HTML files and graphics files to the unique constraints of mobile devices and other Web-enabled products. These devices usually have smaller screen sizes, lower memory, and slower bandwidth rates. In this scenario, transcoding is performed by a transcoding proxy server or device, which receives the requested document or file and uses a specified annotation to adapt it to the client.
A device that is actuated by energy from one system and supplies energy usually in another form to a second system. For example, a microphone is a transducer that transforms sound energy into electrical signals.
(adj.) A type of LCD screen in which the pixels are illuminated from both the front of the monitor��s screen and from behind the screen, combining the illumination characteristics of both transmissive and reflective technologies. Transflective LCDs work under any lighting condition, from complete darkness to bright sunlight.
A device composed of semiconductor material that amplifies a signal or opens or closes a circuit. Invented in 1947 at Bell Labs, transistors have become the key ingredient of all digital circuits, including computers. Today’s microprocessors contains tens of millions of microscopic transistors. Prior to the invention of transistors, digital circuits were composed of vacuum […]
- Transmission Media
Describes the type of physical system used to carry a communication signal from one system to another. Examples of transmission media include twisted-pair cable, coaxial cable, and fiber optic cable.
- transmission path
Also referred to as a transmission channel, the path between two nodes of a network that a data communication follows. The term can refer to the physical cabling that connects the nodes on a network, the signal that is communicated over the pathway or a subchannel in a carrier frequency.
