Table Attributes (HTML)
BGColor:
Some browsers support background colors in a table. The color you select will be expressed as a hexadecimal red-green-blue value. You can enter this value directly or you can enter one of the standard Windows color names. (these color names are currently supported only by Microsoft Internet Explorer).
Width:
you can specify the table width as an absolute number of pixels or a percentage of the document width. The width corresponds to the WIDTH attribute of the TABLE element. You can set the width for table cells as well.
Height:
You can also specify the table (or cell) height as an absolute number of pixels or a percentage of the document height.
Border:
The lines that form the boundary of each table cell when the file is displayed in a browser. You can choose a numerical value for the border width, which specifies the border in pixels, or 'BORDER' (causing the browser to draw the default border). The table border corresponds to the BORDER attribute of the TABLE element. A setting of BORDER="0" will make the border disappear.
Some browsers do not draw borders around empty table cells. You may want to insert a   in each cell when you create the table so that each cell will display border and background color.
CellSpacing:
Cell Spacing represents the space between cells and is specified in pixels.
CellPadding:
Cell Padding is the space between the cell border and the cell contents and is specified in pixels.
Background:
Background Image, will be tiled in Internet Explorer 3.0 and above.
BorderColor:
The color of the border around the table. This is supported properly by Navigator 4.0, and Internet Explorer 3.0 and above.
BorderColorLight:
Light color used to outline two sides of a cell or the table, only supported in Internet Explorer 2.0 and above.
BorderColorDark:
Dark color used to outline two sides of a cell or the table, only supported in Internet Explorer 2.0 and above.

Tape guides.
Little posts inside a VCR to guide the tape from place to place as it plays or is threaded.
TBC (Time Base Corrector).
A device used to rectify any problems with a video signal's sync pulses by generating a new clean time base and synchronizing* any other incoming video to this reference.
Telecine.
Telecine is a term used to describe a device used to convert film to video. In advanced telecine machines, the movie film is digitally sampled and converted to video, frame by frame in real-time. Frame rate is the biggest problem encountered in film-to-video conversion. Movie film has a frame rate of 18, 24 or 30 fps (frames per second) contrasting with the 30 and 25 fps video frame rates of NTSC and PAL respectively.
Tempo.
The rate of speed at which a musical composition proceeds. Usually uses a quarter note as the timing reference.
Test Pattern.
A chart with special patterns, placed in front of a television camera to generate a known reference signal that can be used to adjust the camera and all the equipment downstream from the camera.
Test Signal.
A video (or other) signal containing certain properties (like colour bars) to show whether equipment is working as it should. Test signals meet certain technical specifications useful for calibrating other equipment.
Test Signal Generator.
Electrical device that makes test signals for calibrating and measuring performance of equipment.
Test Tone.
A constant pure sine wave tone or tones played over an audio system to allow critical measurement and adjustment of an audio system both when individual components are being developed and when a complete system is being installed.
Texture.
Data that creates a surface material, including bumps, that you wrap around a wireframe to make it solid. Grass, water ripples, and tree bark are textures.
Texture map.
The data describing the colour, roughness, surface design (i.e., woodgrain) and whether parts will be cut out and replaced by another surface. Several layered texture maps can be used together.
TFT
Thin film transistor. An LCD screen technology used in notebook PCs.
THD (Total Harmonic Distortion).
Distortion derived from the creation of harmonics (multiples of a base frequency signal) in an audio system adding additional frequency peaks to the output.
THD+N (Total Harmonic Distortion plus Noise).
Combination of total harmonic distortion (THD) with noise to achieve a complete figure representing distortions present in an electronic component with lower levels below one percent being preferable. THX Set of specifications and certifications designed by Lucasfilm to ensure optimum reproduction of movie sound and video in movie theaters and home theaters (Home THX program).
THX Reference Level.
Volume level designated to be used as the standard in THX certified theaters and home THX installations setting volume at 85 decibels when fed a continuous test tone and achieving 105 decibel peaks when the volume control is at the reference 0 decibel setting (0 decibels is reference on the volume control with negative numbers being the number of decibels below reference and positive number being the number of decibels above reference).
Three-chip camera.
A TV camera with three pickup chips inside, one sensitive to the red parts of the picture, another sensitive to green and the third sensitive to blue.
Three-tube video projector.
Video projector with three TV picture tubes for a brighter, sharper picture than one-tube models. Three-tube projectors are recognizable by their three lens snouts.
Three-two pulldown.
The motion taken as a movie projector plays a 24-picture-per-second movie into a 30-frame-per-second TV system. One movie picture is scanned three times by the TV system and pulled down, and the following picture is scanned twice; then the process repeats.
Threshold or Coring.
Control on an image enhancer selecting which high frequencies will be boosted (enhanced) and which will be left alone, to reduce graininess in the picture.
Tier.
A level of cable TV programming. Basic level, or tier 1 may be inexpensive.
TIFF.
Tagged Image File Format - general purpose file for bitmapped graphics; developed by Aldus Corporation; in general it can handle any type image. Usually the .TIF documents are 24-bit graphics images.
Timbre.
1.) Specific quality or unique aspect of sound that makes it distinguishable from other sounds of the same volume and frequency.
2.) The property of a sound that distinguishes it from all other. Tone color.
Time Code.
A digital code number recorded onto a videotape for editing purposes. When decoded, the time code identifies every frame of a videotape using digits reading hours:minutes:seconds and frames. Each individual video frame is assigned a unique address, a must for accurate editing. The three time code systems used for video are VITC, LTC and RC (consumer).
Time Code Generator.
Electronic device that makes the time code signal, which may then be recorded on the tape.
Time Code Reader.
Electronic device that decodes the time code from a tape on playback and converts it into recognizable numbers: hours, minutes, seconds, frames.
Timeline.
Like a ruler stretched across the computer screen, the non-linear editor's timeline lists every moment in the TV program; indicating which scenes go where, what graphics and titles appear, what audio will be heard and what transitions occur between scenes.
Tint.
Colour attribute describing a colour somewhat varied from a primary colour such as pink being a tint of red.
Tone.
A steady, audible frequency or steady sound. A test tone is a pure tone or a single, pure frequency sound wave.
Tone Generator.
Electronic circuit often built into mixers, which can create an even, standardized audio signal. Used for checking volume levels, it provides a handy reference tone.
Touch Screen.
A touch-sensitive TV screen whereby viewers can point to or press their fingers against the screen in response to computer questions rather than using a keypad or computer keyboard.
Tracking.
Ability of a CD player, phonograph, DVD player or other device that reads data in a continuous track around a disc to follow that information track and take information from it.
