For a weakly continuous stationary channel with operational sliding-block capacity , it is shown that every stationary, ergodic, aperiodic source with entropy less than is sliding-block transmissible over the channel. It had been shown earlier that a stationary and ergodic source is block transmissible over the channel if its entropy is less than the operational block capacity . If, in addition, the channel is ergodic, it is shown that . An example of a nonergodic weakly continuous channel is given for which .
