| TCP/IP |
Abbreviation for "Transmission Control Protocol over Internet Protocol". The Internet Protocol (IP) is used for the fragmentation and addressing of data and conveys these from the transmitter to the receiver - however does not protect the transmission. The Transmission Control Protocol (TCP) ensures that the sorting of packages reaches the receiver in the right sequence and provides the securing of the communication by confirming the receipt of the package. It corrects transmission errors automatically. |
| Telephoto lens (slide) |
To be used for zooming-in objects which results in a smaller image angle. |
| TFT technology |
The basis of this technology - like the Psi technology - is LCDs. However, only one display is being used. The surface of the display consists of pixels which again consist of three transistors (one for every primary colour). Therefore the name Thin-Film-Transistor- Active-Matrix. The TFT technology has stood the test on the market and is particularly suitable for projections without any moving images. It offers pin-sharp images and clear colour contrasts. One considerable disadvantage is the high loss of light with identical light source, in comparison to other technologies. |
| Throw ratio |
The ratio between the projection distance and image width in m. A throw ratio of 1,3 - 1,8:1 means, i.e., the lens of the projector achieves an image width of 1 m at a projection distance of 1,3 and 1,8 m. |
| Tint |
Tint, tinge; In the video area in particular for the correction of phase errors at NTSC-signals. |
| Triac (slide) |
Electrical control element in slide projectors to infinitely vary the brightness of the projection lamp via impulses while dissolving slides. |
