Provided is a content reproduction device including: a controller configured to: acquire playlist information indicating a reproduction order position of plural pieces of content; acquire reproduction requirement information indicating a condition required for reproduction of each piece of content; acquire reproduction enabling condition information indicating a condition for enabling the reproduction on the content reproduction device; and determine based on the reproduction requirement information and the reproduction enabling condition information whether each of piece of content is reproducible on the content reproduction device; and a storage configured to store information that is based on a determination result obtained by the controller. The controller skip reproducing a piece of content that is irreproducible on the content reproduction device in accordance with the information that is based on the determination result and reproduce another one of the plural pieces of content that is reproducible on the content reproduction device.

Content reproduction device, content reproduction method, and content reproduction system

A connection method of a communication device in a communication system is provided. The communication system includes a plurality of communication devices each having a wireless LAN (Local Area Network) access point function and a wireless LAN child device function and is constructed by connecting a lower-level communication device to an access point of a higher-level communication device. A new communication device is to be added to the communication system executes: a first step of connecting to an access point of an arbitrary one of the plurality of communication devices of the communication system; and a second step of acquiring, from the connected communication device, system information of the communication system including a connection form of the plurality of communication devices.

Connection method of communication device and the communication device

A communication system includes a control terminal device and one or more communication devices. The control terminal device transmits a search message to entire network when the communication device is registered into the communication system. When the communication device is connected to the network, the communication device determines whether a connection position of the connected communication device on the network is the predetermined connection position. When the communication device is not positioned at the predetermined connection position, the communication device cancels the connection with the network and then connects to the predetermined connection position of the network and responds to the search message through the network after the communication device directly connects to the control terminal device and obtains information for connecting to the predetermined connection position of the network.

Communication system, communication device, and communication device management method

An audio system includes a first audio apparatus that receives a first audio signal with a first number of channels and a second audio apparatus connected to the first audio apparatus via a network. The first audio apparatus includes a signal processing unit configured to generate, on the basis of the first audio signal received from the outside of the first audio apparatus, a second audio signal with a second number of channels larger than the first number of channels, and a communication unit configured to transmit a third audio signal corresponding to a part of the channels in the second audio signal generated by the signal processing unit to the second audio apparatus.

Audio system, audio apparatus, and control method for audio apparatus

A communication system includes a plurality of communication devices constituting a network. Each of the communication devices includes a first wireless communication circuit and a second wireless communication circuit. The second wireless communication circuit of a lower-level communication device accesses the first wireless communication circuit of a higher-level communication device, whereby the higher-level communication device and the lower-level communication device are connected so as to constitute the network. Each of the plurality of communication devices stores system information. When any one of the communication devices is disconnected from the higher-level communication device, the disconnected communication device searches for another communication device using the system information and makes reconnection to the communication device detected by the search.
