a) In modeling a 3D world, it is often necessary to create polygons and solids which literally have holes in them. PictureMaker can make 2D holes in individual surfaces and drill 3D holes through convex portions of closed solids. b) A volume in the three-dimensional NTSC spectrum into which an auxiliary sub-channel can be placed with minimal impairment. Holes are found where horizontal, vertical, and temporal detail are simultaneously high. The most famous hole is the Fukinuki hole, but the most common hole is the one carrying the NTSC color subcarrier.

Relatively broad horizontal bars, alternately black and white, which extend over the entire picture. They may be stationary, or may move up or down. Sometimes referred to as a “venetian blind” effect. Caused by approximate 60-cycle interfering frequency, or one of its harmonic frequencies.

a) The entire time between the end of the active picture time of one line and the beginning of the active picture time of the next line. It extends from the start of front porch to the end of the back porch. b) The video synchronizing signal before and after each active television line that defines the border or black area at the left and right side of the display. In a CRT, it hides (blanks out) the electron beam’s retrace path as it returns from the right to the left of the display to begin scanning a new line.

That portion of the scanning line not carrying a picture. In NTSC, the HBI carries a synchronizing pulse and a color reference signal. Some scrambling and other systems add sound and/or data signals to the HBI. Some ATV schemes fill it with widescreen panel or detail enhancement signals. See also Blanking and Blanking Stuffing.
Industry:Software
Describes a picture condition in which the scanning lines start at relatively different points during the horizontal scan. See Serrations and Jitter.
Industry:Software
A pulse at the horizontal sweep rate used in TV cameras. Its leading edge is coincident with the leading edge of the horizontal sync pulse and the trailing edge is coincident with the leading edge of the burst flag pulse.
