a) A mask image is a black and white image, which defines how opaque each pixel is. A mask blocks out certain components of an image but lets other parts show through. b) Pattern used to selectively set certain bits of a word to 1 or 0. Usually ANDed or ORed with the data.

The Digital Information Exchange Task Force (SMPTE, IEEE, ATSC) on digital image architecture has as its goal the multidisciplinary agreement upon and the definition of fully flexible, interoperable, scalable, and extensible systems. The objective is agreement on the structure of digital image files that will facilitate the exchange of such files across the technology interfaces. The scope includes both the rapid, unambiguous but concise identification of the file and its utilization, as well as the organization of the image data itself.
Industry:Software
A screen for displaying text/graphics based on a technology called liquid crystal, where minute currents change the reflectiveness or transparency of selected parts of the screen. The advantages of LCD screens are: very small power consumption (can be easily battery driven) and low price of mass produced units. Its disadvantages presently include narrow viewing angle, somewhat slower response time, invisibility in the dark unless the display is back-lit, difficulties displaying true colors, and resolution limitations.
Industry:Software
A form of interference caused by signal reflections.
Signals that are reflected more take a longer path to reach the receiver than those that are reflected less. The receiver will synchronize to the strongest signal, with the weaker signals traveling via different paths causing ghostly images superimposed on the main image. Since many ATV schemes offer increased horizontal resolution, ghosts can have a more deleterious effect on them than on ordinary NTSC signals. There have been many demonstrations of ghost canceling/eliminating systems and robust transmission systems over the years. It is probable that these will have to be used for HDTV.
Industry:Software
The capability of providing useful and cost-effective interchange of electronic image, audio, and associated data among different signal formats, among different transmission media, among different applications, among different industries, among different performance levels.
Industry:Software
A key that is selectively limited in what portions of the key source will be allowed to cut the hole. Masks are usually square, however, on Ampex switchers mask keys are done by using the pattern system with any pattern shape on the switcher. See Preset Pattern.
Industry:Software
The descriptor is a block of data that enhances the utility of the main data for the user. It may contain, in standardized format, data concerning production, ownership, access, previous processing, etc., relevant to the basic interpretation of the data.
Industry:Software
Used to make a selection from a list of options. If the list is too long to fit inside the given area, a vertical scroll bar moves the list up and down.
Industry:Software
Multiplane animation refers to a type of cel animation where individual cels are superimposed using the painters algorithm, and their motion relative to each other is controlled. Here, the word “plane” and cel are interchangeable.
