Chapter 2. iTV Scenarios > Interactive News

2.9. Interactive News

2.9.1. Enhanced Video

During a news video, additional headline text scrolls from right to left (for roman languages) on the bottom of the screen. The selectable headlines scroll until the viewer starts browsing them using the remote control. When browsing is active the browsing of the viewer controls scrolling. During the browsing the main video and related data continues to display uninterrupted. If the viewer does not browse within several seconds, browsing is deactivated and autoscrolling resumes. On a selection of a headline, the display switches immediately to view the selected story, as if it was a channel selection (see Figure 2.19).
