Abstract: A communication apparatus, a communication system, and a method of same enabling control of a mode of output of additional information such as advertisements on a user side. A program signal and an additional signal are separated from a broadcast signal received by a receiver by a filter. The program signal is stored in a program signal use memory, while the additional signal is stored in an additional signal use memory. When there is an instruction by the user for output of the additional information, a display signal is generated by using the program signal and the additional signal read from the memories, while only the program signal is read from the memory for generation of the display signal in other cases.

Abstract: An authentication apparatus avoiding illegitimate authentication procedures performed based on illegitimately acquired personal ID information of other parties is provided. An authentication apparatus 50 receives personal ID information ID1 of an orderer 31, personal ID information ID2 of a vendor 33, and transaction information by an authentication request from an orderer terminal 11, communicates with a vendor terminal 15, then transmits authentication information indicating a legitimacy of the vendor 33 to the orderer terminal 11.

Abstract: A portable communication apparatus comprising a communication means for making a call and receiving an audio signal distributed from a server by a digital wireless system, a recording means for recording the audio signal received by the communication means, a reproduction means for reproducing the audio signal read from the recording means, and an output means for output in accordance with the reproduced audio signal.

Abstract: There is provided a display apparatus capable of assuredly conveying communicative information to viewers, the display apparatus comprising the following: display means for displaying video picture; switching means for turning power-source ON and OFF; and controlling means for controlling the display means to display communicative information thereon in place of the video picture during a period after the switching means executes an operation to turn off the power source until the power source is actually turned off.

Abstract: An IC memory card comprising a case and a semiconductor memory device therein, able to be loaded into an electronic apparatus to exchange data with the apparatus, able to store data in the semiconductor memory device, and able to be carried outside the apparatus, wherein a through-hole for passing a card connection means for holding use is formed in the case, the function of the through-hole is diversified, the through-hole is utilized as a detection mark when identifying the type of card, a slide shutter having the function of a protection switch is provided, or an opening and closing device is provided at the through-hole itself for passing the closed card connection means, whereby carrying of a number of cards together is facilitated and. handling and storage are improved.

Abstract: A pattern data processing apparatus processes pattern data based on which a predetermined pattern is displayed in a display area. The pattern data has data corresponding to both said display area and a data calculating area outside of said display area, the display area being divided into a plurality of pixels.
