DEFINITION OF TERMS DVD This refers to a high-density optical disc on which high-quality pictures and sound have been obtained by means of digital signals. Incorporation a new video compression technology (MPEG II) and high-density recording tech-nology, DVD enables aesthetically pleasing full-motion video to be recorded over long periods of time (for instance, a whole movie can be recorded). DVD has a structure consisting of two 0.6 mm thin discs which are adhered to each other. Since the thinner the disc, the higher the density at which the information can be recorded, a DVD disc has a greater capacity than a single 1.2 mm thick disc. Since the two thin discs are adhered to each other, there is the potential to achieve double-sided play sometime in the future for even longer duration play. Video CD This contains recordings of pictures and sound whose quality is on a par with that of video tape. This player also supports Video CDs with playback control (version 2.0). Mp3 These contain recordings of music which are compressed, allowing a significantly larger amount of music to be stored on a CD. Angle Recorded onto some DVD discs are scenes which have been simultaneously shot from a number of different angles (the same scene is shot from the front, from the left side, from the right side, etc.). With such discs, the ANGLE button can be used to view the scene from different angles. Subtitles This is the appearance of the dialogue at the bottom of the screen which are prerecorded on some DVD discs. Title number These numbers are recorded on DVD discs. When a disc contains two or more movies, these movies are numbered as title 1, title 2, etc. Chapter number These numbers are recorded on DVD discs. A title is sub- divided into many sections, each of which is numbered, and specific parts of video presentations can be searched quickly using these numbers. Time number This indicates the play time which has elapsed from the start of a disc or a title. It can be used to find a specific scene quickly.(lt may not work with some discs.) Playback control (PBC) This is recorded on a Video CD (version 2.0). The scenes or information to be viewed (or listened to) can be selected interactively with the TV monitor by looking at the menu shown on the TV monitor. Track number These numbers are assigned to the tracks which are re- corded on Video CDs and CDs. They enable specific tracks to be located quickly. 31
