The most interesting function for me is their capability of making movie recommendations.
This means every TV has to remember and capture user’s viewing history, and possibly combine with the server’s knowledge about other viewers’ view data. All the information will be sent and stored in TV maker's server. They will chunk the data, and build movie recommendation engine exactly like Netflix has done.
This is a big advance for data mining. This is possible only after TV is connect to the Internet and store data in the cloud. Traditional TV does not have the computing power nor enough memory to do data mining.
Now we are seeing data mining coming to our home.
