I'm more of a visual learner, so I often have closed captioning turned on on my television. This helps me to better understand what people say. Problem is, the guide on my cable tuner is located on a bar at the bottom of the screen, in the same place the closed captions usually are. Since the tv is
doing the display of the captions, it of course displays them over the guide. What I propose is a simple set of programming that, whenever the cable box is displaying a guide, menu, or anything that is generated inside it, it will automatically stop sending the closed captioning data. Otherwise one has to go to the television's menu and turn off closed captioning, then turn them back on when you're done.

The guide on Manhattan Cable automatically turns off close captioning on our kitchen TV (the one we have close captioning turned on for). |

For a guide to strip out captioning would be trivial. All it would have to do would be to nuke line 21. As a slight improvement, it could replace line 21 with a repeated "clear screen" command to ensure that no previous captioning remained. |

What would be even cooler, though, would be if it could replace all prologue commands for rows 12-15 with prologue commands for rows 8-11, thus shifting the bottom four rows of captioning up four rows. Although the commands to use the middle seven rows are standardized and have been for years, they are still seldom used because some older (by now really old) decoders don't support them. |
