Definition: | difference between the information content I(x) conveyed by the occurrence of an event x, and the conditional information content $I\left(x|y\right)$ conveyed by the occurrence of the same event, given the occurrence of another event y $T(x,y)=I(x)-I(x|y)$ Note 1 to entry: The two events are particularly a message at the message source of a channel and a message at the message sink of the channel. Note 2 to entry: The transinformation content can also be expressed as: $T(x,y)=I\left(x\right)+I\left(y\right)-I\left(x,y\right)$, where | ||

$T(x,y)=I(x)-I(x|y)$

Note 1 to entry: The two events are particularly a message at the message source of a channel and a message at the message sink of the channel.

Note 2 to entry: The transinformation content can also be expressed as: $T(x,y)=I\left(x\right)+I\left(y\right)-I\left(x,y\right)$, where *I*(*y*) is the information content of the event *y*. From this follows that it is symmetric in *x* and *y*: $T(x,y)=T(y,x)$.
