A method, performed by a first terminal in a video call process between the first terminal and a second terminal, includes sending an image including a target device to a server, receiving device information corresponding to the target device sent by the server, virtualizing an operation interface based on the received device information, and displaying the operation interface on a current video call screen, where the operation interface is an operation interface of a control panel or a remote control of the target device, and displaying, on the current video call screen based on data from the second terminal, one or more operations performed on the operation interface by a user of the second terminal on the second terminal.

A first screen device establishes a pairing session between a first screen device and a second screen device. The first screen device presents, in a user interface on the first screen device, a video and one or more media features related to the video. The media features pertain to at least one of a presentation of the video or user feedback about the video. The video is cast from the first screen device onto the second screen device. The first screen device receives, via the user interface, user input indicating a user request to enable presentation of at least one of the media features on the second screen device in connection with the video. In response to the user input, the first screen device causes the at least one of the media features to be presented on the second screen device in connection with the video.

Methods, systems, and media for providing dynamic media sessions with audio stream expansion features are provided. In some embodiments, the methods include: receiving an indication that audio content associated with a video content item is to be presented by a follower device synchronously with the audio content presented by the leader device; identifying candidate follower devices by determining whether devices connected to a local area network are capable of being designated as a follower device; causing a user interface to be presented that indicates each candidate follower device; receiving, via the user interface, a selection of one of the candidate follower devices; and transmitting, from the leader to the selected follower device, control instructions that cause the audio content associated with the video content item to be presented synchronously by the selected follower device with the video content item presented by the leader device.

Techniques are described for expanding and/or improving the Advanced Television Systems Committee (ATSC) 3.0 television protocol in robustly delivering the next generation broadcast television services. Telepresence is provided through over-the-air (OTA) virtual reality (VR) broadcast streams.

Provided is an information processing device capable of operating in accessibility mode of guaranteeing browsing corresponding to disability or functional degeneration of a body of an operator. A source device checks whether each sink device is in accessibility mode at the time of connection, and determines whether or not metadata for supporting disability (for example, audios, videos, texts, vibration information, or the like) is added to the sink device in the accessibility mode at the time of transmission of original image/audio data. The source device changes a metadata transmission method in accordance with whether the accessibility mode of each sink device is turned on or off.

The present disclosure relates to a method, device and system for recording a television program, pertained to field of intelligent device. The method is applied in a router and includes: receiving an instruction for recording the television program, in which the instruction at least includes an appointment period and an identifier of a television channel; and downloading video data of being played by the television channel within the appointment period. By recording the video data via the router, a user may watch the video data recorded by the router within any period.

The present disclosure provides a device control method, which comprises capturing, by a portable device, a first image of a specific area containing a number of electronic devices connected to a communication network; transmitting a connection signal to a selected electronic device on a device list containing all the electronic devices connected to a communication network; determining whether the selected electronic device is in the first image captured based on whether a response has been received from the selected electronic device; identifying the selected electronic device on the device list and the relative position of the selected electronic device on the first image captured upon determined that the selected electronic device is in the first image; and continuing the device identification process until all the connected electronic devices on the device list has been verified, to identify the relative positions of all electronic devices contained in the first image.

A system and a method render internet multimedia content in a network using an application to render the internet multimedia content and/or locally stored multimedia content on one or more rendering devices in the network. The application may provide web browser functions, such as, for example, receiving, processing, decoding and/or rendering the internet multimedia content. The application may have an enhanced user interface which may enable a user to select the internet multimedia content and a rendering device in the network, send the internet multimedia content to the rendering device and/or control rendering of the internet multimedia content on the rendering device.

Embodiments are provided for replacing media items in a queue of a playback device. An example implementation involves receiving, at the playback device, first data indicating an addition of a first media item to a queue. The playback device determines that the first media item is no longer accessible to the playback device at a later second time. The playback device initiates a query for a media item similar to the first media item and receives second data indicating that a second media item has replaced the first media item in the queue, the second media item being similar to the first media item. In response, the playback device initiates playback of the second media item on the playback device.

A method is provided for synchronizing playback of audio an/or video by a plurality of separate devices in a computer network. Each separate device generates a virtual clock in response to a timing of the audio codec of a received audio stream. Either the virtual clock is generated directly in response to the tick counter of the audio codec, or by a periodic measurement of the timing of the audio codec interpolated by a monotonic clock. A sample rate converter may be used to slightly adjust the frequency of the virtual clock.
