The degree to which the coating adheres to the base film.
Anchorage may be checked by measuring the force required to separate the coating from the base film by means of a specially designed plough blade or, more simply, by determining whether the coating can be peeled from the base film by means of ordinary pressure-sensitive adhesive tape.
Industry:Entertainment
A television transmission channel immediately adjacent to an existing channel. For example, channel 3 is adjacent to channels 2 and 4. There are three exceptions to what might otherwise be considered adjacent channels: there is a small gap between channels 4 and 5, there is a large gap between channels 6 and 7, and there is an enormous gap between channels 13 and 14. Adjacent channels figure into ATV in two ways. a) First, it is currently illegal to broadcast on adjacent channels in a single location. Some ATV proponents feel that augmentation channels might someday be allowed to be placed in adjacent channels. If half-size (3 MHz) or smaller augmentation channels are used, all current broadcasters could then be allowed an augmentation channel. Some proponents feel the use of a low-power digital augmentation channel will allow adjacent channels to be used without interference. b) Second, some ATV proposals require that the augmentation channel be adjacent to the transmission channel or require a larger than normal transmission channel, thus occupying a channel and one of its adjacent channels.

Techniques for ATV transmission developed by the DSRC, with support initially from NBC and RCA/GE Consumer Electronics (now Thomson Consumer Electronics) and with later support from such organisations as ABC and HBO. There are two ACTVs. a) ACTV I is a channel-compatible, receiver-compatible system using many different techniques to add widescreen panels and increase horizontal and vertical resolution. Among the techniques are the filling of a Fukinuki hole, time compression, seam-elimination, spatio-temporal filtering, and quadrature modulation of the picture carrier. The last prevents direct compatibility with videotape recorders and with ordinary satellite transmission techniques. b) ACTV II is ACTV I plus an augmentation channel to improve resolution and sound.
