Using Navio Technologies to Create Hybrid Programming
Putting both broadcast television and Internet content on the TV screen is one thing; integrating them in a meaningful, dynamic way is another. Picture-in-picture technology does not solve the problem, for while it displays the two kinds of content at the same time, they remain separate and unrelated. How can Internet content be included with TV broadcast data, and how can broadcast TV be made to appear on the same page as Internet content?

Inserting the Internet Into TV Signals
Navio technology enables producers creating hybrid programming to insert Internet information in the space "between" television signals. In analog television, this space is known as the vertical blanking region or VBI (for Vertical Blanking Interval) - space currently used to carry closed caption data. In digital TV, MPEG2 data streams offer a similar capacity for inserting Internet data alongside the video information. Navio technology takes advantage of the available VBI or MPEG2 data stream bandwidth, which has very high capacity: up to 96 Kbps-twice as fast as the fastest modems now available for accessing the Internet over standard phone lines.
