I'm begining a study about application development for interactive digital TV, and I have found some papers and web sites about it, but I still didn't comprise the process of playing videos in a Xlet.
Supose an existing application (Xlet) that allows users to select and play a video.
How is transmited this video? Does it come from the broadcast stream or from something like a network connection?
If the video comes from the broadcast stream, does it mean the broadcast can be used to transmit different videos for different users?
