An electronic device is disclosed. The device includes a memory, a communication interface, and a processor configured to change, based on an event for turning off the electronic apparatus, first information indicating support for a fixed rate link (FRL) in EEID information stored in the memory into second information indicating no support for the FRL, and provide the second information to a source device connected through the communication interface.

Provided are a device and a method which are capable of realizing an efficient search of metadata such as access information corresponding to acquisition-scheduled data in a reception device. A reception device receives a token which is auxiliary search information for efficiently searching for metadata such as access information related to acquisition-scheduled data of the reception device and performs a search process using the token. The token includes a service worker (SW) search scope token capable of limiting a search scope of access information corresponding to data serving as a management target of a specific service worker (SW) which is a data management program and a service worker (SW) cache scope token indicating that access information corresponding to data serving as a management target of a service worker (SW) is collectively recorded.

This application provides a method for method for television (TV) remote keypress response based on Android operating system (OS) and a TV thereof, and includes: creating a first process when the Android OS is being initialized; executing the first process to obtain a key value of a remote key event; and performing a remote keypress operation according to the key value. The method creates and executes the first process during the initialization of the Android OS, thereby realizing responding to remote keypress during TV start-up, greatly enhancing user experience.

A method for selecting an audio track from an audio and video file. The method includes: selecting one or more audio tracks that support decoding from one or more audio tracks of the audio and video file; selecting an audio track matching a language from the audio tracks that support decoding; selecting an audio track whose supported audio format is an audio format with a first specification from a plurality of audio tracks; selecting an audio track having a first bit rate from the audio track whose supported audio format is the audio format with the first specification; and playing the audio and video file. The first specification of the supported audio format is higher than a second specification of the supported audio format.

A display apparatus, including a communicator; a display; an interface configured to connect to a dongle storing a first application based on a first OS; and a processor configured to: based on receiving a user command to execute the first application while the dongle is connected to the interface, transmit, to the dongle, a signal requesting execution of the first application through the interface, based on transmission of the signal, receive, from the dongle through the interface, an image received by the dongle from a first server by executing the first application, and additional information related to the image, execute a second application based on a second OS and receive, from a second server through the communicator, an additional image based on the additional information, and display the image on a first area of the display and display the additional image in a second area of the display.

A display apparatus, including a display; an interface configured to couple with a dongle, wherein the dongle and the display apparatus are configured to use different operating systems; a user input device; and at least one processor configured to, based on receiving a first execution image of an application from the dongle, display the first execution image on an area of the display, based on receiving a user operation at a point within the area, convert first coordinate information representing a location of the point relative to the display into second coordinate information representing the location of the point relative to the area, and transmit the second coordinate information to the dongle, and based on receiving a second execution image of the application from the dongle, display the second execution image, wherein the second execution image is generated by the dongle based on the second coordinate information.

Techniques for improving media applications are described. In an example, a system presents content based on an execution of a media application that includes a first streaming protocol library. This execution includes streaming the content based on the first streaming protocol library. The system receives a user interaction with the media application indicating a request for a media player to present the content. The system receives, from the media application, content information about the content and selects a second streaming protocol library from a plurality of streaming protocol libraries of the media player. The second streaming protocol library corresponds to the first streaming protocol library. The system presents the content based on an execution of the media player and on the content information. This execution includes streaming the content based on the second streaming protocol library.

A computer-implemented method for controlling a virtual reality equipment comprises following steps. At first, a first application sends a request for image related data. Then, a camera framework layer sends an instruction for camera control in respond to the request from the first application. Then, a camera hardware abstraction layer responds to the instruction from the camera framework layer. Then, a control layer controls the camera hardware abstraction layer to send a control command to the second application for image related data. Then, the second application provides a virtual reality data captured by a virtual camera in a virtual reality world as the image related data.

An electronic device includes a processor and a non-transitory recording medium; an electronic device application to communicate with a companion device; and a WebSocket server to connect the electronic device application with a companion device application of the companion device.

A reproducing device includes a reproducer that reproduces a content, a communicator that establishes a direct wireless connection to an information terminal, and a controller. The controller determines whether the information terminal is a previously permitted information terminal or not when the communicator receives a content reproduction request from the information terminal through wireless connection. The controller performs first control to power on the reproducer, and issues an instruction to perform the content reproduction to the reproducer, when it is determined that the information terminal is the previously permitted information terminal, and when the reproducer is powered off. The controller does not perform the first control when it is determined that the information terminal is not the previously permitted information terminal.
