An Internet content overview and implementation on an IP based set-top box

Today consumers can use their computer to access a lot of different content on the Internet. But the computer is only one unit, which makes it a constant source of conflict. This could easily be avoided by buying one computer for every member of the family. On the other hand, if you could provide support for Internet content on the IP based set-top box (IP-STB) a real value to the consumers will be added since it would be one less computer to buy and maintain.

This thesis covers the investigation of different content sources on the Internet and the analysis of the requirements they put on a set-top box. It also covers the adaptation of the set-top box to one of these sources. An IP based set-top box (IP-STB) is mainly constructed for access to TV and video distributed over a high speed network…
