Proposed descriptor developed by SMPTE Working Group P18.41. This proposed SMPTE recommended practise is intended to provide a method of coding video index information in which various picture and program-related source data can be carried in conjunction with the video signal. There are three classes of video index data based on type and use of the data. Class 1: Contains information that is required to know how to use the signal. Class 2: Contains heritage information for better usage of the signal. Class 3: Contains other information not required to know how to use the signal.
Industry:Software
A type of two-channel downmix for multichannel audio programs. Lo/Ro downmixes are intended for applications where surround playback is neither desired nor required.
Industry:Software
A) To take, or be capable of taking, several different signals and send them through one source. b) To combine multiple signals, usually in such a way that they can be separated again later. There are three major multiplexing techniques. Frequency division multiple (FDM) assigns each signal a different frequency. This is how radio and television stations in the same metropolitan area can all transmit through the same air space and be individually tuned in. Time division multiple (TDM) assigns different signals different time slots. Different programmes can be broadcast over the same channel using this technique. More technically, the MADs use TDM for luminance and chrominance. Space or path division multiplex allows different television stations in different cities to use the same channel at the same time or different people to talk on different telephones in the same building at the same time. c) A stream of all the digital data carrying one or more services within a single physical channel. d) To transmit two or more signals at the same time or on the same carrier frequency. e) To combine two or more electrical signals into a single, composite signal.
Industry:Software
A system or scale used for measuring temperature. Absolute zero is 0° Kelvin or –273°C. The “color” of white light is expressed in terms of degrees Kelvin, the colour of light emitted when an ideal object is heated to a particular temperature.
Industry:Software
One of the most recent developments of a magnetizable particle for magnetic tape, products from pure iron and having very high coercivity in the range of 850 to 1250 oersteds.
Industry:Software
The creation of an image in the photographic or electronic medium from an image-concept (painted or generated by computer graphics, for example).
Industry:Software
The impedance or resistance (load) that a cable places on a signal being transmitted through it. In the case of a highfrequency signal, signal-to-cable matching is essential to prevent signal deterioration. The cable should be terminated by a specific load resistance, usually 50 or 75 ohms. Improper cable loading results in signal distortion, ghost images, colour loss, and other adverse phenomena. Most video inputs have the proper termination built in.
Industry:Software
Minimum circuitry required to allow the microprocessor to function.
Usually consists of the microprocessor, clock circuit, interrupt and DMA control lines, and power supply.
Industry:Software
Given two databases with the same number of vertices, a metamorphosis causes the first to become the second. This is an animation tool.
Industry:Software
An optional package which adds additional flags and menus to ADO 100, including Mosaics, Posterization, Solarization and Mask submenu, Target Defocus flag and Background menu, Border flags and Sides submenu.
