CNN International Video App uses progressive download

I am a firm believer that the best uses of technology disappear. Good technology, like good design, gets out of your way and let's you do what you want to do. Only technology geeks care about how the developer did what the developer did. Considering we are all technology geeks here, I want to highlight apps you see in Ovi store that have some cool uses of web technology that you may not notice. 

The CNN International Video app supports progressive download to deliver the video content, a Flash innovation that was optimized by personnel within Nokia specifically for use in this application. Check it out.

Note that this app is not available in all countries.

Hi Kevin,

First, the video doesn't play: not only here, but on YouTube, either. :(

Second, is it progressive download or streaming? Read http://www.dncompute.com/blog/2006/05/04/flash-video-streaming-vs-progressive-download.html for a brief summary on the differences.

Finally, I recall when we were implementing this feature for the S60 Browser. It was a nice feature and btw we had a hard fight with the following dilemma: DRM-protected (DRM v1) content cannot be shown progressively until the whole stuff is downloaded, because the user pays for the content only *after* successfully downloading and storing it.

Hi Tote,

When I connected this morning the video worked, both here and directly on YouTube. If it still doesn't work for you please LMK and I'll look into the problem.

I'm tracking down the progressive/streaming question now.

BTW -- it's good to still see you in the community. I hope the new gig is working out well.

progressive vs. streaming

I just exchanged some emails with Robert Burdick, the Forum Nokia Chief consultant who worked with CNN on this app. He is currently out of the office with a poor Internet connection, so allow me to post on his behalf.

Robert clarifies that the CNN app does, indeed, use progressive playback of FLV files within the Flash Lite app. Robert worked with the Nokia Flash Lite R&D team in Bangalore to remove a number of memory limitations such that playback over progressive now works "almost as well" as streaming, without the disadvantages of trying to stream multiple files over mobile networks for a service like CNN.

The improvements developed in working on the CNN app are now built into Nokia touch-based devices.
