Abstract
A point-to-multipoint data transmission method includes separately transmitting, by an electronic device, audio data to a first earbud and a second earbud through two connected isochronous streams (CISs) of a same connected isochronous group (CIG), where the two CISs share a CIG presentation point of the CIG, where the CIG presentation point is a time point at which the first earbud and the second earbud play the audio data, transmitting, by the electronic device, the audio data to the first earbud through the first CIS from an anchor point of the first CIS, and transmitting, by the electronic device, the audio data to the second earbud through the second CIS from an anchor point of the second CIS.
Claims20
A method, comprising:
- sending audio data to a first earbud of a true wireless stereo (TWS) headset through a first connected isochronous stream (CIS) in a first connected isochronous group (CIG) from a first anchor point of the first CIS;
- and
- sending the audio data to a second earbud of the TWS headset through a second CIS in the first CIG from a second anchor point of the second CIS,
- wherein the first CIS and the second CIS share a CIG presentation point of the first CIG, and
- wherein the CIG presentation point is a time point at which the first earbud and the second earbud play the audio data.
A method implemented by a true wireless stereo (TWS) headset, wherein the method comprises:
- receiving, using a first earbud of the TWS headset, audio data from an electronic device through a first connected isochronous stream (CIS) in a first connected isochronous group (CIG) from a first anchor point of the first CIS;
- receiving, using a second earbud, the audio data from the electronic device through a second CIS in the first CIG from a second anchor point of the second CIS, wherein the first CIS and the second CIS share a CIG presentation point of the first CIG;
- and
- playing, using the first earbud and the second earbud, the audio data at the CIG presentation point of the first CIG.
An apparatus, comprising:
- a memory configured to store a computer program code;
- and
- one or more processors coupled to the memory, wherein the computer program code causes the one or more processors to be configured to:
- send audio data to a first earbud of a true wireless stereo (TWS) headset through a first connected isochronous stream (CIS) in a first connected isochronous group (CIG) from a first anchor point of the first CIS;
- and
- send the audio data to a second earbud of the TWS headset through a second CIS in the first CIG from a second anchor point of the second CIS,
- wherein the first CIS and the second CIS share a CIG presentation point of the first CIG, and
- wherein the CIG presentation point is a time point at which the first earbud and the second earbud play the audio data.
