  • Patent number: 10268648
    Abstract: [Problem] To reduce user's workload when preparing a playlist. [Solution] A playlist preparation terminal 2 carries out face recognition processes on the image data of listeners captured for each room from a room A to a room C, and generates listener information including the atmosphere, age group, and a male-to-female ratio of a listener group made up of the listeners captured in the image data. The playlist preparation terminal 2 then prepares a playlist by selecting music data from among music data belonging to the genre information preliminarily associated with the listener information, and multicasts the playlist together with the designation data for the wireless speakers 1-1 to 1-3 from which to output music. As a result, the playlist preparation terminal 2 allows the wireless speakers 1-1 to 1-3 from which to output the music to reproduce the music data according to the playlist and output the music.

  • Patent number: 10210876
    Abstract: [Problem] To provide an audio device with which it is possible to efficiently utilize the storage capacity of a storage device for storing audio data. [Solution] In this audio device 1, in accordance with user profile information stored in a profile information storage unit 102, audio data inputted to an audio data input unit 103 is subjected by a filter unit 104 to a process of cutting a frequency band higher than the highest frequency audible to the user) and/or a frequency band lower than the lowest frequency audible to the user, and the data is then encoded by a codec unit 105, and stored to an audio storage device 100. Audio data can thereby be stored in the audio storage device 100 in compressed form with no noticeable decline in sound quality to the user, making it possible to store more audio data, such as music, in the audio storage device 100.

  • Patent number: 10044733
    Abstract: A method is disclosed for generating a media playlist by a media rendering device having a proximity detector. The proximity detector detects a first identification device, receives a first identification associated with the first identification device, and selects a first preference list associated with the first identification. The proximity detector detects a second identification device, receives a second identification associated with the second identification device, and selects a second preference list associated with the second identification. The media player generates a combined preference list based upon the first preference list and the second preference list and generates a playlist of songs based on the combined preference list.

  • Patent number: 10034255
    Abstract: Described herein are systems and methods for synchronization in a networked environment. For example, some embodiments provide methods for synchronizing a client device having a client media time reference with a server device having a server media time reference. In some cases such methods are embodied in computer readable code that is executable on one or more processors. Furthermore, some embodiments provide hardware, such as networked media devices that are configured to perform such methods. In overview, in some embodiments a client obtains timing information from a server and, on the basis of this timing information, applies an adjustment to a client control time reference, thereby to synchronize the client media time reference with the server media time reference. Some embodiments are particularly directed to the situation where there is a desire to synchronize networked media devices across a combination of wired and wireless networks.

  • Publication number: 20170329570
    Abstract: [Problem] To improve the operability of a sound level operation performed with respect to a plurality of audio devices. [Solution] A control screen 25 is displayed, said control screen 25 comprising: channel faders 26-1 to 26-4 which individually accept sound volume level operations for wireless network compliant speakers 1-1 to 1-4; and a master fader 27 which accepts a sound volume level operation collectively for the wireless network compliant speakers 1-1 to 1-4. In the master fader 27, a minimum value end portion 271 is displayed in a position indicating a scale value that is the same as the minimum value from among the scale values indicated by each of the channel faders 26-1 to 26-4, and a maximum value end portion 272 is displayed in a position indicating the scale value that is the same as the maximum value from among said scale values. The master fader 27 thus has a width W corresponding to the minimum value and the maximum value of said scale values.

  • Patent number: 9785399
    Abstract: A Zone Control service is disclosed which provides for hierarchically managing a plurality of networked media subsystems. This can provide a layer of abstraction for the collection in the form of a single Renderer zone interface represented by a delegated zone controller. This hierarchy establishes a virtual super-system. Although a Zone Control services can be advertised on all networked media devices, the services will typically be unavailable while a device is subservient to, or equivalently under the control of, a zone controller. A single instance of the Zone Control service can reside in a Services Device, co-existing with a Group Control service.

  • Patent number: 9407017
    Abstract: [Problem] To achieve compatibility between push-type and screw-type terminals of mounted printed circuit substrates. [Solution] A speaker terminal attachment base (1) allows both push- and screw-type connectors (2, 3) to be attached thereto. A connector anchoring boss part (111), whereby a terminal part (121) with a through hole (1211) is anchored, is formed upon an attachment base (1), and a through hole (1112), which connects to the through hole (1211) of the terminal part (121), is formed upon the connector anchoring boss part (111). The through hole (1112) comprises a large diameter part (11121), and a small diameter part (11122). When the screw-type connector (3) is attached, a nut (5) which sends a male screw part (312) of the connector (3) in the axial direction is non-rotatably housed in the large diameter part (11121) before a terminal plate (12) is attached.
