Abstract: A first index corresponding to a first conversation operation and a second index corresponding to a second conversation operation are selectably displayed on a screen of a video output device. When a communicator receives a conversation request from another device, a controller determines whether the first index or the second index is selected on the screen or whether an operating member is operated. If the first index is selected, the controller performs the first conversation operation. If the second index is selected, the controller performs the second conversation operation. If the operating member is operated, the controller performs the second conversation operation.

Abstract: The possibility that one who is not accustomed with manipulation may cause inadvertent alteration or deletion by using an easy-remote control is reduced. A data processing apparatus includes a reception section for distinguishably receiving a first remote control signal sent from a first remote control and a second remote control signal sent from a second remote control; a processor for generating image data representing a list of contents by using, from a storage medium on which content-related information is recorded, information being read from the storage medium, such that image data representing a different list of contents is generated depending on whether the first remote control signal is received or the second remote control signal is received; and an output section for outputting the image data representing the list of contents.

Abstract: A user can use a plurality of communication devices to sign in to a communication system. A recording message addressed to himself/herself may be recorded in a distributed manner in the plurality of communication devices. One of the communication devices is requested to display a list of incoming call information while signing in to the communication system using user information. The one communication device requests the other communication device to send incoming call information corresponding to the same user information. The incoming call information corresponding to the same user information is transmitted to the communication device in one terminal from the other communication device. In the one communication device, the incoming call information transmitted from the other communication device is received, and list data is generated based on the received incoming call information.

Abstract: Audio data transmitted from another communication device is received by a receiver, and the received audio data is output to a speaker of a television. Audio is generated based on the output audio data, and the audio is input to a microphone of a camera/microphone device. Audio data corresponding to the input audio is input to an echo cancellation processing unit. An amount of distortion of the input audio data with respect to the received audio data is detected by the echo cancellation processing unit. It is determined whether or not the amount of distortion of the audio data detected by a distortion detector exceeds an acceptable amount. When the amount of distortion of the audio data exceeds the acceptable amount, notification data for presenting to the user a request for change of an output condition of the audio in the television is produced by a notification signal producer.

Abstract: When a receiver in a control LSI receives a conversation request from another device, a controller in the control LSI determines whether a camera/microphone device is connected to a USB interface in a communication device. If it is determined that the camera/microphone device is not connected to the USB interface in the communication device, the controller in the control LSI performs a message recording operation.

If the first index is selected, the controller performs the first conversation operation. If the second index is selected, the controller performs the second conversation operation. If the operating member is operated, the controller performs the second conversation operation.
