  • Patent number: 12231873
    Abstract: [Problem] To enable the desired number of channels to be listened to at a lower cost and without wasting resources. [Solution] Process multi-channel digital audio signals by coordinating between a plurality of AV amp devices 1. An operation terminal 5 assigns audio channels to be processed, to each AV amp device 1, and, on the basis of the signal processing time for each AV amp device 1, determines an output delay time for each AV amp device 1 so that the output timing for analog audio signals matches for all AV amp devices 1. Each AV amp device 1 decodes input digital audio signals into analog audio signals for audio channels assigned to that AV amp device 1 by the operation terminal 5 and delays the output of the decoded analog audio signal, by the output delay time for that AV amp device 1 determined by the operation terminal 5.

    Abstract: [Problem] To enable a sound bar and a wireless speaker to be grouped and ungrouped through a simple operation. [Solution] When a user moves a controller 3 closer to a sound bar 1. the sound bar 1 reads tag information from an RFID tag 30 of the controller 3 by using an RFID tag reader 10. detects that the user has performed an operation to move the controller 3 closer to the sound bar 1, and checks a host group state. When group formation is in progress, an ungroup notification is transmitted to a wireless speaker 2, which is a participating member of the group. to ungroup the group. and information relating to a slave of the ungrouped group is stored as immediately preceding slave information. However, when ungrouping is in progress. a group formation notification is transmitted to the wireless speaker 2 identified by the immediately preceding slave information to form a group with the wireless speaker 2.

  • Publication number: 20240098415
    Abstract: [Problem] To improve operator convenience in controlling the ON/OFF states of a plurality of wireless speakers. [Solution] A wireless speaker 1, when instructed through a power button or by a controller 2 to transition to an ON state, causes said wireless speaker 1 itself to transition to an ON state and also transmits a command for ON state transition to each of other wireless speakers 1 belonging to the same group as said wireless speaker 1. When instructed to transition to an OFF state, said wireless speaker 1 transmits a command for OFF state transition to each of the other wireless speakers 1 belonging to the same group as said wireless speaker 1, and also transitions to the OFF state. If an ON state transition command has been received from another wireless speaker 1, then the wireless speaker 1 transitions to the ON state, and if an OFF state transition command has been received, then the wireless speaker 1 transitions to the OFF state.

  • Publication number: 20240089655
    Abstract: [Problem] To provide technology for setting an audio playback environment compatible with adding speakers. [Solution] An audio device 1 corrects, for each connected speaker 2, an audio playback signal output from speakers 2-1 to 2-3, in accordance with filter information registered in association with that speaker 2. When a new speaker 2 is connected, identification information is acquired from that speaker 2, the identification information is used to query a management server 4, and acoustic properties of that speaker 2 are acquired from the management server 4. The acquired acoustic properties are then compared to target prescribed acoustic properties, filter information is generated for causing the audio playback signal output from the speaker 2 to approach the prescribed acoustic properties, and the generated filter information is registered in association with the speaker 2.

    Abstract: A second media rendering device in a network is synchronized with a first media rendering device in the network. At a first time s1, the second media rendering device sends a request for a current audio sample index from the first media rendering device. The first media rendering device receives the request for the current audio sample index from the second media rendering device. The first media rendering device sends a message including a first current audio sample index equal to a value for a first media rendering device internal sample index. At a second time s2 the second media rendering device receives the first current sample index value from the first media rendering device. The second media rendering device determines a transmission latency, and estimates an updated first media rendering device internal sample index value.
