  • Publication number: 20190297373
    Abstract: A communication apparatus is provided which acquires content held by an external apparatus based on information related to the content that is received from another communication apparatus and plays back the content. The communication apparatus further receives playback control information about the content from the other communication apparatus. Upon detecting a disconnection of a communication path between the communication apparatus and the other communication apparatus, the communication apparatus performs control in such a manner that a notification based on the disconnection of the communication path is issued to a user.

  • Patent number: 10390223
    Abstract: A communication apparatus acquires information about a communication-parameter setting process from a different communication apparatus and determines whether the acquired information includes identification information for identifying the different communication apparatus. If it is determined that the identification information is included, an authentication request is transmitted by unicast based on the identification information. If it is determined that the identification information is not included, the authentication request is transmitted by broadcast.

  • Publication number: 20170215069
    Abstract: A communication apparatus executes an authentication process with a first other communication apparatus based on information acquired from an image obtained by capturing code information of the communication apparatus and receives, from the first other communication apparatus, first information shared between the first other communication apparatus and a second other communication apparatus. The communication apparatus transmits a search signal including second information based on the received first information and has a smaller amount of information than the first information, and transmits the first information to the second other communication apparatus in a case where a response signal in response to the search signal is received from the second other communication apparatus, and then executes a setting process for setting a communication parameter for communicating with the second other communication apparatus.

  • Patent number: 9288677
    Abstract: A wireless terminal which newly joins a wireless communication system transmits a message containing its identification data to an access point in the wireless communication system at a communication parameter setting start. Upon receiving the message, the access point determines whether or not the wireless terminal has been registered. If it is determined that the wireless terminal has not been registered, the access point determines whether or not the wireless terminal is a setting target device of communication parameters based on the identification data contained in the message. If it is determined that the wireless terminal is a setting target device, the access point sets communication parameters for the wireless terminal.
