How does news applications work other than RSS Feed based applications?

I know some of them take the RSS content from the source site.But sometimes I see, those applications show ->

Title Description Date Image video etc.

Even though when I see the original site's rss, image, video is not there in rss.

So how does one get that to show in there applications?

Some applications even shows feeds from magazine sites, newspaper sites. How do these applications work?

I am creating an application which will link to different news sites feeds categorized (like top news, technology, games, articles etc.)

On the front page it will show the website names, then on selection of any news site it will get the feed from that website and show it to user.

So I would like to know

All the fetching of data from should be done on user selection or data should be prefetched?
Detailed information I want to fetch from the original like provided in the rss data. How should I go about it?
