In the present specification, a digital device and a method of processing data in said digital device are disclosed. Here, a digital device according to an embodiment of the present invention comprises: a memory; a user interface unit that receives a menu request signal through a remote application executed in an external device; a display unit that displays an executed application; and a control unit that determines the properties of the received menu request signal on the basis of the application being displayed and generates menu data, implements controlling to transmit the generated menu data to the external device and output the menu data through a screen of the external device, and when a menu item selection signal of the menu output from the external device is received, implements controlling to transmit or activate menu data corresponding to the menu item selection signal.

Systems and methods for providing augmented arrays for audio playback are disclosed. An example playback device includes a first transducer configured to output audio along a first acoustic axis and a second transducer configured to output audio along a second acoustic axis. The playback device is configured to receive a source stream of audio content including at least a first input channel and a second input channel. The device plays back first audio output via the first transducer based on the first input channel and directed along the first acoustic axis, and plays back second audio output via the second transducer based on the second input channel and directed along the second acoustic axis, wherein the second audio output at least partially cancels the first audio output along a first spatial region offset from the first acoustic axis.

In accordance with increasing communication demand, means for efficiently providing mass downstream communication at a low cost are desired. Accordingly, a communication system providing supplemental downlink as well as multicast communication comprising a display control device for causing a display unit to display a video, and a communication terminal having an image capturing unit for directly capturing the video displayed by the display unit or capturing a video projected or reflected on a wall surface or the like is provided, wherein the display control device includes a video acquiring unit, a region identification unit, a video generating unit, and a display control unit, and the communication terminal includes a region identification unit, a decoding unit, and a mechanism for communicating a control signal for supplemental downlink by the above-described optical communication using means other than optical communication (means such as WiFi, mobile data communication or the like).

An image-capturing device includes: an image sensor that captures an image of a subject to output an image-capturing signal; a development processing unit that generates development data based on the image-capturing signal; and an output control unit that outputs the development data to an external device in a predetermined transmission format via a connecting member that connects the image-capturing device to the external device. The output control unit outputs the image-capturing signal to the external device via the connecting member in the predetermined transmission format.

Methods, systems, and computer-readable media for secure offline transmission of a plurality of data segments from a sending device to one or more receiving devices. The sending device and the one or more receiving devices may communicate via an offline local network. A secure, encrypted container may be created at the receiving device to temporarily cache the received data segments one at a time and the encrypted storage container prevents access by one or more applications of the receiving device to data stored therein based on storage instructions from the sending device. The encrypted container may be configured to store the data segments such that less than all of the data segments are stored at the receiving device at any one time.

An Audio/Video (A/V) receiving device may include a display, a Radio Frequency (RF) receiving module configured to receive an RF packet from an A/V transmitting device, the RF receiving module including a plurality of antennas, and a microcomputer configured to obtain a distance between the A/V transmitting device and A/V receiving device and when the obtained distance is changed, display a first message indicating that a number of antennas to be turned among the plurality of antennas is changed according to the change of the distance.

A playback device includes programming for connecting to a first wireless local area network (WLAN) and storing a first set of network configuration parameters including an identifier of the first WLAN and a first security parameter for the first WLAN. The functions also include disconnecting from the first WLAN, receiving a second set of network configuration parameters including an identifier of a second WLAN and a second security parameter for the second WLAN, and storing the second set of network configuration parameters. The functions also include reconnecting to the first WLAN using the stored first set of network configuration parameters and, after reconnecting to the first WLAN, transmitting, absent user request, the second set of network configuration parameters to at least one other playback device that is connected to the first WLAN for storage on the at least one other playback device that is connected to the first WLAN.

The disclosure relates to a soundbar and a method for automatic surround pairing and calibration of a surround sound system. The soundbar includes two built-in microphones on the left and right respectively, which can be used for determining relative positions of left and right surround speakers. When the relative positions of the left and right speakers are not correct, configurations of left and right surround channels can be automatically swapped with each other without manually swapping physical positions of the surround speakers by a user. In addition, latencies including a latency of each channel of a main system may also be calibrated, and magnitude compensation may be achieved by calculating a filter compensation coefficient of each line and merging it into an original filter. The automatic surround pairing and calibration of the surround sound system may be one-click completed automatically by the user by pressing a start button.

A method for displaying media content on devices respectively linked to media players from a group of media players. The method includes the acts of: transmitting to the media players configuration data including data; transmitting data corresponding to the media content to at least one of the media players; transmitting to the media players data corresponding to a multicast address and to an entry port; selecting by the server a master media player among the at least one media player which received the data corresponding to the media content; sending by the master media player a multicast media stream using the multicast address and the entry port, the multicast media stream being obtained by the master media player from the data corresponding to the media content.
