A lack of vertical synchronization which causes the picture as observed on the picture monitor to move upward or downward.
Industry:Software
A B/W video output available as an option on AVC series switchers that provides display of all switcher adjustments, pattern menus, and diagnostic tools.
Industry:Software
Term used for a type of camera movement where the camera actually moves left to right (or vice versa) across a scene.
Industry:Software
A method to adjust the average length of an audio frame in time to the duration of the corresponding PCM samples, by continuously adding a slot to the audio frame.
Industry:Software
A processing step which intentionally reduces the precision of DCT coefficients.
Industry:Software
Additional sections of picture that, when added to a television image, change a 1.33:1 aspect ratio into a wider one. Many ATV schemes transmit these panels separately from the main picture.
Industry:Software
An information service of 200-700 “pages” covering a wide range of topics including TV Schedules, News, Financial Market prices, Comment, Reviews, Concert and Theater information. Subtitles are typically transmitted on page 888 in the UK, on pages 199/299/399 in Belgium and Holland, on page 150 in Germany, and on page 777 in Italy. There are a number of variant character sets used, but the encoding is identical and all English alphabet characters plus numbers and most punctuation can be handled by any decoder. Includes support for eight colors, and limited block graphics, and selective revealing of underlying TV picture.
Transmitted on a variable number of lines (specified in header which contains basic information such as time, date, and channel), starting on line 12 and continuing for 7-8 lines typically. Found on broadcasts and some Laserdiscs; recording of TeleText signals is marginal on S-VHS, almost impossible on VHS, hence, the PAL/625 version of CC.
Industry:Software
In tape recording, the shortest distance between two peaks of the same magnetic polarity; also, the ratio of tape speed to recorded frequency.
Industry:Software
Refers to the polarity of the black portion of the picture signal with respect to the white portion of the picture signal.
For example, in a “black negative” picture, the potential corresponding to the black areas of the picture is negative with respect to the potential corresponding to the white areas of the picture; in a “black positive” picture, the potential corresponding to the black areas of the picture is positive.
The signal as observed at the broadcasters’ master control rooms and telephone company television operating centers is “black negative.”
Industry:Software
The effect that occurs when a piece of equipment can no longer process the frequency which is being fed into it (a reduction in amplitude with an increase of frequency).
