A video processing method and an apparatus are provided in embodiments of the present disclosure. The method includes: detecting an operation instruction of a first user; in response to the operation instruction, displaying an image collected by a camera of the first terminal on a chat page of the first user with a second user in real time, superposing and displaying remaining information except the image within a preset area on the image; and sending the image collected by the camera of the first terminal to a second terminal in real time as a video frame, so that the second terminal displays the image on a chat page of the second user with the first user in real time, and superposes and displays remaining information except the image within a preset area on the image; where the first terminal is a terminal corresponding to the first user.

The present disclosure relates to a broadcast receiving apparatus and an operating method thereof. The broadcast receiving apparatus according to an embodiment of the present disclosure includes a network interface unit configured to communicate with an external server through a network; a broadcast receiving unit configured to receive a broadcast signal; a storage unit configured to store a database containing information on at least one broadcasting service provider; and a controller, wherein the controller checks whether access to the network is possible through the network interface unit, checks, when the access to the network is possible, a status of an application, which is registered in an application server, that contains information on a broadcasting service provider, through the network interface unit, determines whether it is required to update at least some of information contained in the database, based on a result of checking the status of the application, receives, when the update is required, an application containing information required for the update from the application server, updates at least some of the information contained in the database, based on the received application, and receives the broadcast signal based on the information contained in the database through the broadcast receiving unit. Various other embodiments are possible.

A screen casting method is applied to a source device having a display and a speaker. The screen casting method includes receiving first data and decoding the first data, displaying the decoded first data through the display and/or outputting the decoded first data through the speaker, receiving text information from the server and parsing the text information, and displaying the parsed text information through the display, where the text information is associated with the first data. A first operation of performing screen casting to a target device is detected, and in response to the first operation, sending a download address of the first data and a download address of the text information to the target device.

A method, a system, and a computer-readable recording medium implement a fast-switching mode between channels in a multi-live transmission environment. A composite image in which images of multiple channels are synthesized into one image in a live transmission environment is received as one stream to configure a multi-view composed of the images of the multi-channels and, as an image of a specific channel is selected in the multi-view, the original image of the specific channel is received and the multi-view may be switched to a full-view of the image of the specific channel.

Embodiments included herein generally relate to measuring a latency of a playback device. For example, a method includes: determining a first latency of a playback device; determining a second latency of the playback device; comparing the second latency to the first latency to determine whether an event occurred at the playback device; and in response to detecting a latency change between the second latency and the first latency indicating the occurrence of the event, adjusting a timing of a data stream provided to the playback device based on the latency change.

A system for facilitating configuration of an audio system tests the existing audio system configuration by playing reference audio clips of various different genres of programming, the audio of which is received by a microphone of a remote control device or other handheld mobile device at various different listening points in the room. The system then compares the audio signal representing audio of the reference audio clip received at the microphone to a reference audio signal representing the reference audio clip and determines other audio characteristics. The system then determines, based on the comparison and other characteristics of the room (e.g., furniture layout, room construction materials, wall treatments and current speaker positioning) suggested changes to a configuration of the audio system to increase audio quality of the audio system for playing audio associated with the various different genres of programming.

The virtual ambient illuminance sensor system disclosed herein provides a method including detecting presence of an external device in vicinity of the device, wherein the external device is communicatively connected to the device, communicating with the external device to determine that the external device has an illuminance sensor, based at least in part on determining that the external device has an illuminance sensor; receiving an ambient illuminance snapshot from the external device, storing the ambient illuminance snapshot from the external device in the memory, and generating an ambient illuminance report for an operating system of the device.

Embodiments are provided for satellite volume control. An example method includes receiving an input at a playback device to adjust a volume for a plurality of playback devices that are grouped for synchronous playback of audio content, wherein the plurality of playback devices includes the playback device. The method also includes sending a first message over a network from the playback device to a device associated with the plurality of playback devices, the first message including information based on the input, wherein the information is used to adjust the volume of the plurality of playback devices. The method also includes receiving a second message at the playback device over the network, the second message including information for the volume of the playback device, wherein the volume is based on the adjusted volume of the plurality of playback devices.

Systems and methods for summarizing captions, configuring playback speed, and rewriting the caption file for a media asset are disclosed. The system determines whether to display the original captions or a summarized version of the captions, which are based on user's language proficiency level, reading pace, and historical data, and can be generated either on-demand or automatically when rewinds and pauses are detected. The caption file which includes the original captions can be rewritten. The system determines whether to stream a caption or a rewritten file to a media device based on user or system selections. In the absence of a caption file, or when the caption file cannot be summarized, the playback speed of the media asset is slowed down to provide additional reading time to the user.
