Abstract

Video graphics system which, by means of a graphics cursor, permits the identification of encoded surfaces of images represented on a screen. In order to do this, there are added to the parameters of the encoded surface, for each surface, an identifier which can be read by slices in the course of readings effected on a plurality of successive frames. An identification memory permits the accumulation of all the slices until the complete acquisition of the identifier. This situation is brought to the attention of the user.
