The present invention is a method for the synchronized, real-time transmission of content data between two geographically separated computing devices. It involves synchronization of timing between devices, receipt of content data at the first device, and real-time transmission to the second device. The second device sends a cue indicating which content data should be included in a broadcast feed and when. Based on this cue, the first device selects the specified content for inclusion at the designated time, and then transmits the broadcast feed to one or more consumers. This method enhances efficiency and synchronization of content transmission between remote devices, allowing real-time adjustments to the broadcast feed.

To enable quick access to content by communication when reproducing content using both broadcasting and communication on a receiving side. [Solution] The receiving method includes a receiving step of receiving content transmitted using both broadcast waves and a communication channel, and a playback step of playing the content when control information is received, the control information including information indicating that there is content transmitted via the communication channel and information for playing the content via the broadcast waves and the content via the communication channel, which information relates to the content transmitted via the communication channel. In the receiving step, the base layer of the content is received via the broadcast waves, and the extension layer is received via the communication channel. In the receiving step, information indicating which base layer asset corresponds to which extension layer asset is received via the communication channel. In the receiving step, information indicating the type of control information for the content transmitted via the communication channel is received via the broadcast waves.

There is provided a method for providing audio content from a first LE Audio transmitter device (10) or a second LE Audio transmitter device (20) to an LE Audio receiver device (30-1, 30-2; 32-1, 32-2; 34-1, 34-2), comprising: synchronizing the LE Audio receiver device and the second LE Audio transmitter device with the first LE Audio transmitter device; broadcasting, by the first LE Audio transmitter device using a first transmitter configuration and a first Broadcast Isochronous Stream (BIS) (40), a first audio content for reception by the LE Audio receiver device; and providing a transmitter device handover (100) by interrupting broadcasting of the first audio content by the first LE Audio transmitter device and starting broadcasting a second audio content, for reception by the LE Audio receiver device, by the second LE Audio transmitter device using said first transmitter configuration and said first BIS.

A method implemented by a communication system, including at least a first electronic device and a second electronic device, includes that the first electronic device plays multimedia content. The first electronic device sends first synchronization information through broadcast, so that the second electronic device receives the first synchronization information, where the first synchronization information includes at least a first address, and the first address is an obtaining address of the multimedia content. In response to a preset operation, the first electronic device establishes a near field wireless communication connection to the second electronic device, and the second electronic device caches the multimedia content based on at least the first address. The first electronic device sends a control instruction to the second electronic device by using the near field wireless communication connection. The second electronic device plays the multimedia content based on the control instruction.
