S-Video Out
4 pin socket used to carry high quality video signals. Luminance and Chrominance signals are carried separately to optimise picture quality.

SD Memory Card
Next generation of MultiMedia card, standing for 'Secure Digital'. It is a solid state storage device for still images, video footage and music. Data can be encoded to protect copyright material. More than 520 companies worldwide support the SD standard. It is increasingly popular as a 'bridge media' that lets different types of devices share data.

SECAM
The French broadcast system. Sequential Coleur A Memoire uses 625 lines scanned at 50Hz.

SIS
This function makes it possible to snap off a still shot (VGA) while continuing to record a moving picture. There isn't even any need to change recording modes. The moving pictures are recorded onto tape, and the still is recorded onto the SD Memory Card. This two-in-one capability makes it possible to catch sudden photo opportunities without interrupting a moving picture scene.

Smart Accessory Shoe
Port on the top of the camcorder, which allows the user to attach peripheral equipment. The port has connections that allow the equipment to draw power and information from the camera.

sRGB
Abbreviation for Standard RGB. sRGB is the international color space standard created by the IEC (International Electrotechnical Commission). Performing all color adjustments in this color space minimizes color disparities from input and output data collected via PC peripheral devices, such as digital cameras, printers, and monitors.

Subwoofer
A speaker dedicated to producing powerful low frequency sounds - that's bass to you and me! DVDs with Dolby Digital 5.1 or DTS 5.1 soundtracks are encoded with a Low Frequency Effects channel especially for those trouser-flapping explosions, seismic spacecraft, rumbling thunderstorms, etc.

Super Image Stabilizer
In recording situations where shaking is likely to happen i.e. when using zoom mode, filming from a vehicle or whilst walking, this function will stabilize the recording. (Also see Optical Image Stabilizer).

Super Shadow Mask
Precision engineering increases the pitch aperture ratio of this shadow mask, ensuring the optimum amount of beam current passes through the mask and lands accurately on the faceplate. The result is a higher, more natural brightness as well as an overall improvement in picture performance.

SVGA
Abbreviation for Super Video Graphics Array. Resolution is 800 x 600 pixels. One of the standard PC display modes.

SXGA
Abbreviation for Super eXtended Graphics Array. Resolution is 1280 x 1024 pixels. This resolution is a vertical and horizontal expansion of XGA (1024 x 768 pixels).

THX
Apparently, when the original Star Wars movie was shown in cinemas during the late seventies, filmmaker George Lucas was unhappy with its sound and picture quality. He set-up THX which specialises in high quality post-production work so that a film's sound and picture standard is of the highest calibre. It's not just films that can be 'THX certified' - the company also specifies exacting standards for cinema construction, professional equipment and home AV components, too. Incidentally, the name THX is derived from THX 1138, the first film Lucas made while he was a student in 1971. It starred Robert Duvall as a robot called THX 1138 and there have been many direct and subtle references to the title in other George Lucas films: it was the number plate of Harrison Ford's roadster in American Graffiti and the numbers are also mentioned in the Star Wars and Indiana Jones films. The initials stand for Tomlinson Holman's eXperiment - Tom Holman is now a professor at the University of Southern California and widely respected as a film audio pioneer and a lead developer of the THX system (for which he won an Academy Award in 2001).

Time Slip
Lets you watch one recorded programme while recording another at the same time. Chase Play is an associated feature which lets you watch a recording that has already started while continuing to record.

USB
Universal Serial Bus. A connection port for transfering digital data. Fast data transfer speed of up to 12 Megabits per second.

USB Terminal for PC
Video and stills stored on memory cards can be transferred to a PC at high speed via USB terminal. Attach your images to email or post on the Web. (all models)

USB2.0
High-speed 480-Mbps data transfer interface. Approximately 40 times faster than USB1.1 (12 Mbps).

UV Filter
A filter designed to cut UV (ultraviolet) light. Also used as a lens protection filter.

UXGA
Abbreviation for Ultra eXtended Graphics Array. Resolution is 1600 x 1200 pixels. This resolution is a vertical and horizontal expansion of XGA (1024 x 768 pixels).

Variable Bit Rate
A 'bit' is a single piece of digital data. This data is compressed so that you can record more on a single disc. The Variable Bit Rate continuously controls the amount of compression for a more efficient recording.

Velocity Modulation
Regulates the speed of the electron beam to keep the picture tightly focused at all times.

Vertical Aperture Control
Sense and adjusts brightness in the vertical plane.

VFZ
Abbreviation for Vector Format for Zooming. This next-generation digital image format uses lossless compression to save an image at 2/3 its original size. Unlike standard digital compression, which makes it difficult to reuse data, this format allows the easy enlarging and reducing of data, with no loss in quality.

VGA
Abbreviation for Video Graphics Array. A graphics system developed by IBM. Resolution is 640 x 480 pixels and uses 16 colors. Widely used as a standard for PC graphics systems.

WMA
This is a compression format developed by Microsoft* Corporation to be played in Windows Media Player. It achieves an even better sound quality than MP3s, with a smaller file size. *Microsoft and its logo as well as Windows and Windows NT, Windows Media are trademarks or registered trademarks of Microsoft Corporation of the U.S in both the United States and other countries.

XGA
Abbreviation for eXtended Graphics Array. Resolution is 1024 x 768 pixels. One of the standard PC data display modes.

YpbPr
Component Video signal the same as YUV where Y = luminance; Pb = blue minus luminance; and Pr = red minus luminance.

YUV
A modified form of the component RGB video signal. The black and white (luminance) part of the signal is removed from the red and blue and added to the green. This gives greater detail to the picture, as the human eye perceives detail in green better than red or blue

Zoom
Allows the user to get a close up image of far away subjects. In the optical range the image is magnified by the lens. In the digital range the image is enlarged electronically.

Zoom Microphone
This system incorporates four independent electret condenser microphones and is linked with the zoom operation of the lens, so the microphones' directionality and sensitivity are adjusted as the zoom is activated. The directionality adjusts in 256 steps from wide to zoom, so voices and sounds are recorded naturally and correspond with the images. Wide mode emphasises the stereophonic ambience, while zoom mode narrows the recording direction to capture monaural-like sound from a distant subject.
