Patent ID: 8191090

Claim:
A communication apparatus comprising: a receiving means for receiving a signal comprised of a program signal and an additional signal; a separating means for separating the program signal and the additional signal from said received signal; a determining means for determining whether to output said additional signal; a log information generating means for generating log information comprising instructions corresponding to the additional signal; an output signal generating means for generating an output signal, wherein, when the determining means determines to output the additional signal, the output signal generating means generates the output signal by using said separated program signal and additional signal, and wherein, when the determining means determines not to output the additional signal, the output signal generating means generates the output signal by using said separated program signal only; and an outputting means for outputting information in accordance with said generated output signal; wherein determination of whether or not to output an image corresponding to the additional signal is made as a function of user preference after receiving said additional signal, wherein when a viewing fee is determined if a determination is made not to output the additional signal, wherein a viewing fee is reduced by a predetermined amount when the displayed additional signal is an advertisement and the viewing fee is increased by a predetermined amount when the displayed additional signal is an additional service, wherein a user of said communication apparatus is charged based on log information indicating whether or not the image corresponding to the additional signal was chosen to be output that is transmitted from said communication apparatus.
