Some TV stations rebroadcast their evening news later at night. You may have observed that the part of the late night news which is a rebroadcast of the evening news has virtually no errors. This happens because the captioner gets the opportunity to fix all the errors before the next air time. At the time of rebroadcast, the captioner simply presses only one key to send one line of captions at a time from the script prepared earlier for the evening news. Since one whole line goes out at a time, captions are painted on the screen very smoothly from left to right. You can easily identify these captions. You may sometimes even see the captions appear before they are spoken!
