Abstract: According to the present invention, there is provided a processing device (10) which includes a sound collection unit (11) that collects an environmental sound outside a vehicle, a filter unit (14) that performs filtering for emphasizing a sound characterizing a current position of the vehicle of which the environmental sound is collected, from the environmental sound collected by the sound collection unit (11), and a processing unit (12) that causes the environmental sound including the filtered sound to be output to the inside of the vehicle.

Abstract: According to the present invention, there is provided a processing device (10) which includes a sound collection unit (11) that collects an environmental sound outside a vehicle with plural microphones and a processing unit (12) that amplifies the environmental sound collected by the sound collection unit (11) and causes the amplified sound to be output to an inside of the vehicle. The processing unit (12) sets an amplification factor of the environmental sound collected by some microphones to be different from an amplification factor of the environmental sound collected by other microphones.

Abstract: A content delivery system includes a content management element for managing one or more of contents, a multicast delivery element for delivering a multicast stream of the content or contents, a unicast delivery element for delivering a unicast stream of the content or contents, and a terminal. In response to a delivery request, the content management element transmits to the terminal, first information identifying the multicast delivery element and second information identifying the unicast delivery element. The terminal receives and reproduces a multicast stream corresponding to desired content according to the first information. When special reproduction is requested, the terminal requests the unicast delivery element to perform the special reproduction according to the second information. In response to the request for special reproduction, the unicast delivery element delivers the unicast stream for the special reproduction to the terminal.
