A data transmission and reception method for a sink device which is connected to a plurality of source devices by means of a high definition multimedia interface (HDMI), according to an embodiment of the present invention, comprises the steps of: receiving an allocation of an internet protocol (IP) address; transmitting device information about a sink device to a control point through a network; and transmitting service information about a supportable service by the sink device to the control point through the network.

A master device providing an image to a slave device providing a virtual reality service is provided. The master device includes: a content input configured to receive an input stereoscopic image; a communicator configured to perform communication with the slave device providing the virtual reality service; and a processor configured to determine a viewpoint region corresponding to a motion state of the corresponding slave device in the input stereoscopic image on the basis of motion information received from the slave device and control the communicator to transmit an image of the identified viewpoint region to the slave device.

Provided is an image that is comfortably viewed and operated by a user. An electronic device acquires user information related to a relative position between a user and a display unit. Then, the electronic device transmits the user information to an information processing device. The information processing device includes a communication unit and a control unit. The communication unit receives the user information related to the relative position of the user and a display unit which is acquired by the electronic device from the electronic device. Further, the control unit performs control to decide a display mode of an image transmitted from a source device on the display unit on the basis of the user information received from the electronic device.

A slave relay station is adapted to serve and/or host pages comprising a simplified graphic user interface (GUI) encoded in a widely recognized format such as, for example, HTML or WML. The GUI embodies activatable links corresponding to control functions for configured appliances. A wireless phone or other device with network access and the capability to process and present such pages, for example via a Web browser, may then be utilized to effect control of such appliances by simply navigating to the network address of the slave relay station, obtaining an appropriate GUI page, and interacting with the links.

The present disclosure discloses a method and apparatus for accessing a terminal device camera to a target device. The method includes: establishing a connection channel between the terminal device camera and the target device; starting the terminal device camera and obtaining image data captured by the terminal device camera; and transmitting the obtained image data to the target device through the connection channel established.

A media playback system is configured to automatically establish a connection, via a wireless network, to an internet-based media platform, delivering copyright-protected media assets and establishing access to some or all of those assets. No prior user configuration, set-up, sign-up or other user identification for that media delivery platform is needed because the system automatically and uniquely identifying itself to the media delivery platform to enable that platform, or an access control component associated with the platform, to determine if the system is licensed to receive streaming media, irrespective of the user of the system. The system can include a portable remote control device that enables a user to select copyright-protected media, such as streaming media, from the media delivery platform. The remote control is used to control a user interface displayed on a TV that has been re-purposed to serve as the streaming media output.

Disclosed is a system and method for reducing the total latency for transferring a frame from the low latency camera system mounted on an aerial vehicle to the display of the remote controller. The method includes reducing the latency through each of the modules of the system, i.e. through a camera module, an encoder module, a wireless interface transmission, wireless interface receiver module, a decoder module and a display module. To reduce the latency across the modules, methods such as overclocking the image processor, pipelining the frame, squashing the processed frame, using a fast hardware encoder that can perform slice based encoding, tuning the wireless medium using queue sizing, queue flushing, bitrate feedback, physical medium rate feedback, dynamic encoder parameter tuning and wireless radio parameter adjustment, using a fast hardware decoder that can perform slice based decoding and overclocking the display module are used.

Methods, systems, computer readable media, and apparatuses for providing synchronous supplemental experiences are presented. According to one or more aspects, a video signal may be transmitted to a display device, and a sync signal may be transmitted to at least one other device. The sync signal may include an identifier of a program currently being displayed and a time value indicating a current point in time of the program. In at least one arrangement, the sync signal may cause the at least one other device to access content synchronization data; determine, based on the content synchronization data, that at least one supplemental experience corresponds to the identifier of the program and the time value; and present the at least one supplemental experience to a user.
