Voice coding section 101 generates voice data and image coding section 102 generates image data, an error decision bit is added to each of these data and these data are multiplexed and transmitted. A Device Facility Manager executing on the MFP represents the MFP by responding to discovery, metadata, and logging requests with device location, metadata and logging information. Prediction of a future or expected value corresponding to at least one parameter associated with the communication channel can drive operational mode selectionadaptation in accordance with video coding. Two n-type electrodes are arranged on the carrier control layer so as to dispose the p-type electrode between the two n-type electrodes in an in-plane direction of the substrate.
