I found this really interesting. Martin over at Creative Weblogging's Digital TV has an article that mentions a product called Gotuit On Demand which he describes:

Gotuit Media Corp. has developed a product, called "Gotuit On Demand," that combines segment metadata with VOD content. This is a fancy way of saying that viewers can use their remote control to quickly access the specific parts of an on-demand show that interest them.

Martins points out why this technology is newsworthy:

DigitalTV included this little news bit because it shows yet another aspect of video-on-demand (VOD). That is, the television program can be indexed and skipped through just like a DVD (provided Dan succeeds on his mission). Does this mean we might be skipping whole segments of the content as well as skipping the ads? imaging having each segment on a news program indexed, we could probably get through the program in record time!

Read Ad-skipping? How about content-skipping!
