So well the approach is that uh basically the idea is to send a message to the T_V_ set , as Mael has pointed , and it will be decoded by the T_V_ and usually we it is easier to have uh keys or buttons with which people can uh press and then um changing a button will basically uh change the message which is being sent to the T_V_ and uh  um
Mm-hmm.
a and basically it sends an internal signal and decoded by the receiver. So p as um Anna has said that this ki people are interested in things which are you don't need to k press the keys , people are can have a speech recognition but this is uh s a question which will we have to see later.
Mm-hmm.
