| S-Video |
High quality video signal, where the light signals are separated from the colour signals. DIN A4 pin connector, i.e. used with S-VHS recorder. |
| SCART |
Also called EURO AV connector. The maximum 21 pin cable transmits all audio and video signals with only one connector. SCART is also suitable for S-Video. |
| Screensaver |
Means it saves the screen. |
| SD Memory Card |
Compact and solid memory medium in credit-card sized format Panasonic, at present with up to 512 Mbyte memory capacity. Currently the smallest design of electronic memory cards. Advantage: Large memory capacity, fast access time, erasure protection. The standard is supported by more than 230 suppliers. The cards are used among others in MP 3 players, digital projectors, digital cameras, PDAs. Can be used via a PCMCIA adapter in any PC with PCMCIA slot. |
| SECAM |
"Sequential Couleur A Memoire" (sequential memory recreation of colours). Television standard used among others in France, Czech Republic, Slowakia and Japan. Like PAL, the number of lines is 625, the frame rate is 25 frames. |
| Selective autofocus (slide) |
With the focusing key the automatic focusing can be adjusted at any time. The Autofocus is then automatically switched off and after pressing the slide changer it is switched on again. |
| Single slide holder |
This enables the quick presentation of a slide without having to sort it into the magazine. Wrongly sorted images are grabbed instantly. |
| Slide AV |
Umbrella term for any imaginable connection of slide and audio, a modern term for an audo image show. |
| Slide control unit |
External control unit for the programing between a slide projector and a tape recorder. |
| Slide gate |
Dual-plane presssure system slide gate for optimal slide positioning. Horizontally : the slide is pushed to the slide gate for plane positioning. Vertically the slide is simultaneously adjusted at the sides so that the slide is exactly aligned at the dissolve. Projectors which are used for professional Multimedia shows (slide shows with dissolves etc) require this feature. For example Kodak: all Ektrapro except E 320 have this feature. |
| Slide light box |
For slide preview some projectors feature a slide light box at the top side which is visible when opening a sliding cap. |
| SmartMedia Card |
Very small memory card, i.e., as used for digital cameras. They are even smaller and cheaper than PCMCIA memory cards. |
| Soft-slide-change (slide) |
Soft slide changer that prevents a hard light change during the slide transportation. |
| Softlift (slide) |
By pressing a key, the slide softlift automatically goes up and a slide can be inserted laterally into the duct. The softlift is pressed into the gadget again and the image is projected. Suitable for sorting slides into the magazine and replacing slides during the projection or for the correction of reversed slides. Single slide holder. |
| Specular (projection screen) |
Reflection feature of projection screens. Specular projection screens reflect the incident light along the projection axis twice as much as diffuse reflective projection screens. The viewing angle is approx. 20 to 35 degree. The luminance factor is approx. 2.4. |
| Spiral tube (slide) |
Old Kodak S-AV lenses are based on a spiral tube. However, they are not used in the Ektalite models but only in the Ektapro series. The lenses are screwed clockwise from ahead into the lens holder. The focusing is adjusted by turning the lens. |
| Split-Screen |
Some plasma displays have an in-built split screen function that allows the interconnection of several plasma displays to one large plasma screen. Each plasma display shows one part of the total image. |
| sRGB |
sRGB is a colour standard developed by Microsoft for identical colours at PC peripherals. Is increasingly used with digital projectors. The aim is the exact display of colours of the original artwork. |
| Standby (slide) |
(Pause). Presentations can be interrupted and continued at any time. |
| Subtractive colour mixture |
Complementary colour mixture deposited on white surface turns out black. This method is used with the four colour printing. The basic colours are yellow, cyan and magenta. Black is used for saturation. Opposite additive colour mixture. |
| SVGA |
"Super Video Graphics Array". Graphic standard for PCs with a maximum resolution of 800 x 600 pixels. |
| SXGA |
"Super Extended Graphics Array". Graphic cards with a resolution of 1.280 x 1.024 pixels. |
