Moving images present a unique set of scaling challenges. In NTSC TV, fields alternate every 16.6 ms. Any object that moves significantly between field-refresh times will appear distorted. If an image is scaled in the Y direction by assembling two fields into a single frame, the distortion is even more exaggerated. When the full frame is scaled down using decimation (line-dropping), a group of lines from one field can end up adjacent to a group of lines from another field, causing a jagged, stepped appearance in the scaled image. This distortion is often more noticeable than the distortion in the original TV image. Therefore, a general rule for scaling down is to use either the even or odd field from each frame. If the final image is to be less than one-half the size of the original, scale the single field down to the required size. If the final image is to be greater than one-half the size of the original, use one field, then increase image to the required number of lines with line replication.

In general switcher terms, a pattern is any geometric shape which grows, rotates, or pivots and in so doing removes the foreground video while simultaneously revealing the background video. Strictly speaking, a pattern is a fully enclosed shape on the screen. This definition is our internal view, but not consistent with the industry. Typical patterns are rectangles, diamonds, and circles.
Industry:Software
A series of macroblocks, all placed within the same row horizontally.
Slices are not allowed to overlap. The division of slices may vary from picture to picture. If “restricted slice structure” is applied, the slices must cover the whole picture. If “restricted slice structure” is not applied, the decoder will have to decide what to do with that part of the picture which is not covered by a slice. Motion vectors are not allowed to point at the part of the picture, which is not covered by a slice. Note that Main Profile uses “restricted slice structure,” that is, all the slices put together must cover the picture.

A television standard accepted in all parts of the world.
CCIR recommendation 601 is currently the closest there is to a world standard.
It is accepted throughout the world, but can be used with either 525- scanning line or 625-scanning line picture. HDTV 1125/60 Group is attempting to promote its system as a world HDEP standard, but Zenith suggests the same for 3XNTSC, and there are other candidates.
