A first example playback device includes one or more processors and a non-transitory computer-readable medium storing instructions that, when executed by the one or more processors, cause the first playback device to perform functions. The functions include generating a mixed audio signal comprising one or more components of a first audio stream and one or more components of a second audio stream; and playing the mixed audio signal, where the one or more components of the second audio stream of the mixed audio signal played by the first playback device are played in synchrony with a second playback device configured to play the second audio stream. An example non-transitory computer-readable medium and an example method, both related to the first example playback device, are also disclosed herein.

Systems and methods for providing an authenticated groupcast stream of content to destination receivers are disclosed. A method may include receiving information indicating that a media capturing source(s) located at a premises and destination receivers are included in a group. Content captured from a media capturing source(s) may be received. The content may include an image(s)/video(s) and a destination network address associated with the destination receivers. The content may be copied. The number of copies of content may correspond to a number of the destination receivers. A respective copy of the content may be sent to the destination receivers.

Some aspects include a method for synchronizing at least two devices, including: connecting the at least two devices using an application executed on each of the at least two devices, wherein: a same media is executed in synchronization by the at least two devices using the application; and an input received by the application executed on a first device of the at least two devices actuates a same response on the at least two devices.

The method includes: A first electronic device displays a control center on a first interface, where the control center includes a device list including one or more electronic devices, and the one or more electronic devices and the first electronic device are in a same content continuation system. The first electronic device receives a first selection operation of selecting a second electronic device from the one or more electronic devices by a user. In response to the first selection operation, the first electronic device determines whether the first electronic device is a source device or a target device of a current content continuation task. If the first electronic device is the target device of the current content continuation task, the first electronic device switches content in the second electronic device to the first electronic device for continuous playing.

Example techniques related to polices for media playback systems. An example implementation involves a computing system receiving data representing a request to play back first audio tracks on one or more first playback devices of a first media playback system. The first media playback system is associated with a first subscriber to a streaming media service and the first media playback system is physically located in a first commercial establishment. The computing system determines that the first subscriber is associated with one or more first subscriber policies of the streaming media service and sends instructions to play back the first audio tracks on the one or more first playback devices according to the one or more first subscriber policies of the streaming media service.

An entry device for communicating external network signals between an in-home network and an external network, for communicating in-home network signals within the in-home network, and for preventing the in-home network signals from being communicated from the in-home network to the external network, the entry device includes a signal attenuation and communication device comprising one or more directional couplers, the signal attenuation and communication device being configured to permit upstream and downstream external network signals to communicate between an entry port and a first network work, and between the entry port and a second network port, and to block and permit communication of in-home network signals between the first network port, the second network port, and the entry port at least partially depending on a direction in which the in-home network signals are travelling.

A method and system for synchronizing an audio signal and a video signal includes a source device receiving an audio-video signal comprising the audio signal and the video signal. The video signal has a video time stamp. The source device communicates the audio signal from the source device to a first sink device through a wireless network with a second time stamp and communicates the video signal to the second sink device with the video time stamp. The second sink device generates a synchronization (synch) signal and communicates the synch signal to the first sink device. The first sink device compares the synch signal to the second time stamp, adjusts a relative timing of the playback of the audio signal in response to comparing and generates an audible signal from the audio signal.

An image display system includes: a display device; an image supply device coupled to the display device in such a way as to be able to bidirectionally communicate and supplying an image signal; and an operation terminal having a plurality of operation buttons. The operation terminal transmits an operation signal in response to an operation on the operation button. The display device displays a first image supplied from the image supply device and a second image generated by the display device. On receiving the operation signal, the display device decides a degree of priority of the first image and the second image. The display device transmits a signal to stop updating the first image to the image supply device and executes processing based on the second image when the degree of priority of the second image is higher than the degree of priority of the first image.

An electronic apparatus which registers a device to a server by using a voice, and a method therefor are provided. The electronic apparatus includes a communication circuit, a microphone, a memory for storing computer executable instructions, and at least one processor configured to execute the computer executable instructions to acquire, from a voice received through the microphone, information on an external device which a user wishes to register, based on an external device corresponding to the acquired information being searched through the communication circuit, control the communication circuit to transmit information on an access point to the external device to enable the external device to communicate with a server, and control the communication circuit to transmit a registration request with respect to the external device to the server.

The present disclosure relates to an image display apparatus and an operating method thereof. The image display apparatus according to an embodiment of the present disclosure includes a display configured to display an image; an interface unit configured to have at least one communication module, and to transmit and receive a signal including data; and a controller, wherein the controller, through the interface unit, transmits a request signal including data for a specific communication channel to the outside, checks whether a response signal to the request signal is received in the specific communication channel, and when the response signal is received in the specific communication channel, performs a communication connection of Wi-Fi Direct method with an external device that transmitted the response signal, based on the response signal. In addition, various embodiments are possible.
