Claim of US Patent No. 10,368,376

1. A data relay device, comprising:a first chip configured to wirelessly connect to multiple physical sink devices;
a second chip configured to:
create one or more virtual sink devices configured to be wirelessly detectable by one or more physical source devices, in response to the one or more physical source devices wirelessly connecting to the second chip, obtain data from the one or more physical source devices, the wireless connection between the first chip and the multiple physical sink devices comprises one or more Bluetooth connections, to wirelessly connect to the multiple physical sink devices, the first chip is configured to register the multiple physical sink devices in the profile, the wireless connection between the second chip and the one or more physical source devices comprises one or more Bluetooth connections, the created the one or more virtual sink devices correspond to the registered multiple physical sink devices, the physical source devices comprise a first physical source device paired with a plurality of first physical sink devices of the physical sink devices and a second physical source device paired with one or more second physical sink devices of the physical sink devices; and
transmit the data to the first chip, causing the first chip to relay the data to the first physical sink devices, the first chip is configured to stream the first data to the first physical sink devices each via a Bluetooth connection, to relay the data to the second physical sink devices, the first chip is configured to stream the second data to the second physical sink devices each via the Bluetooth connection; and
the first and second data is played simultaneously and respectively at the first and second physical sink devices.
