CLOSE CAPTIONING SYSTEM IN WINDOWS BASED GRAPHICS SYSTEM

摘要

A method and apparatus for correcting distortion of characters included in an auxiliary data signal received with a video signal. The distortion is corrected by generating a signal representing a background and foreground of both a first character and a second subsequent character. The background and foreground of the first and subsequent adjacent character are then rendered. It is then determined whether the first character is rendered in italics. If so, a foreground color of the first character is re-rendered. Additionally, where a replacement character is received for the first character, it is determined whether the first character is rendered in italics. If so, the foreground and background color of at least a portion of the second subsequent character is re-rendered. A signal representing a background and foreground of a replacement character is generated. The foreground color and the background color of a replacement character superimposing the first character is then rendered.
