The addition of text, symbols, and graphic elements to a video image. Titles may be added to a video scene during shooting or in postproduction.
Sophisticated titling devices allow the user to prepare text and graphics in various sizes, fonts, and colors to be triggered later, one-byone, at appropriate places within a production. Many video cameras include basic titlers or permit externally-generated titles to be mixed with the video image during shooting. The Video TitleMaker 2000 is a powerful tool for titling.

Data broadcast according to the DVB object carousel specification is transmitted according to the DSM-CC Object Carousel and DSM-CC Data Carousel specification which are defined in MPEG-2 DSM-CC.
Industry:Software
A processor function allowing the operator to select any incoming video source for viewing prior to actual use. Typically, each signal can be previewed on its own monitor. This is an effective method to check work before going “on the air.” The Digital Video Mixer includes a separate preview output which can be used to preview all four of its video input signals on-screen simultaneously.
