iconography of tv news starting sequences

The opening sequence sets the tone of the program and some typical iconography in starting sequences that you commonly see would be clocks or rushing graphics and camera movements these connote the urgency and importance of what is about to be shown.

Another common element would be transparent objects and eyes this shows us that it is unchanged and therefore unbiased and what is being said is not their opinions but fact.

When showing the world from space or landmarks from cities this tells us that they are going to be covering stories and activities from either the globe or the world.

Showing technology and satellites connotes that they are using everything they can to deliver the news to you.

The use of male voiceovers connote both power and authority which again can show the importance of what is being said.

Beat-driven, fast-paced music that often involve brass instruments are used to grab the attention of the viewer and to announce themselves the beat often gives time.

metallic blues and strong reds are used often and as the public world officials use these colors it grabs the attention of the viewer and shows it is official and important news. 

Newsreaders are supposed to deliver news in a 'transparent' manor to the viewer so should remain neutral and serious as well as delivering news with urgency and importance, this is done by limiting facial expressions and by being sat ready at their desk to deliver the news, they also show this by addressing you what seems directly as they look straight into the camera.
