TV NEWS, LITTERED SCREEN AND IRRELEVANT INFORMATION

A viewer of a TV news broadcast expects certain elements. Video or moving images is a basic expectation. And so is sound or an audio component. Pictures, whether still or animated, are also acceptable. Alternative visual aids like maps and other graphic presentations help to illustrate stories. But the screen should not be littered with additions that don't add value to the viewing experience. 

In the example above, there are some graphical details that have nothing to do with the story on air.

Imagine visiting a website, only to encounter the back-end...with all the coding 'gibberish'?

That information could be mighty useful to the webmaster or coder, but to a user on the site, it's unsightly and on the extreme end of the useless scale.

The same applies to tuning in to a news channel, only to be met with irrelevant information like 'video converter'.

Again, it could be a technical error.

But yet again....there ought to be editorial mechanisms of minimising the impact of the resultant visual terror.
