What is the difference between showing captions on screen or on a caption board?
If you do not use a caption board, captions must be displayed over the picture on the monitor or screen. The smallest caption board costs at least $3,000 and therefore adds to the overall equipment and installation budget. HFC recommends the use of caption boards because they allow for captions to be continually displayed without covering any on-screen program material. The correct size and placement of the caption board is essential for proper readability.
