A system comprises a receiver to receive a main content. The system further comprises a detector to detect a placeholder in the main content for placement of a media object. Further, the system comprises an obtainer to obtain a plurality of media objects having placement attributes corresponding to the placeholder in the main content, where a placement attribute is indicative of characteristics of a media object compatible with the placeholder. The system further comprises a selector to select one of the plurality of media objects for being placed in the placeholder of the main content, based on a user profile. Further, the system comprises a generator to generate a final content indicative of the selected media object embedded in the main content.

A method and an apparatus for adjusting a view for a target device, an electronic device, and a computer-readable medium are provided by the embodiments of the present disclosure. A specific implementation of the method includes: determining whether a currently playing video is a video of a first type in response to detecting a change of a posture of the target device; and adjusting a display direction of the video-stream-play view to match the posture of the target device and adjusting a display position and/or transparency of the at least one video-stream-play interactive control in response to determining that the currently playing video is the video of the first type. This implementation achieves matching of the view with the posture of the target device and enhances adaptability of the video-stream-play interactive control with the adjusted video-stream-play view.

In one aspect, a method includes receiving first content at a content-presentation device and presenting the first content, the first content comprising a first audio-content component. The content-presentation device may receive second content comprising a second audio-content component. The content-presentation device may determine a switch time at which to switch from presenting the first content to presenting the second content. During a first time interval prior to the switch time and ending at the switch time, the volume of the first audio-content component may be decreased to zero. At the switch time, the content-presentation device may switch from presenting the first content to presenting the second content. During a second time interval beginning at the switch time and ending at a second time after the switch time, the volume of the second audio-content component may be increased from zero to a non-zero volume level.

The disclosure provides an animation configuration method and a display device. The display device includes: a screen; a rotating component for driving the screen to rotate; and a controller. The controller is configured to receive a command for rotating the screen from a user, control the rotating component to drive the screen to rotate, monitor component rotation information of the rotating component, and configure a rotation animation based on the component rotation information.

The present disclosure relates to methods, devices, and systems for presentation of multimedia content. In an aspect of the present disclosure, a method includes receiving, at a processor of a mobile device, a plurality of images from a camera, at least one image of the plurality of images including an object. The method also includes displaying a camera video stream based on the plurality of images, displaying three dimensional (3D) augmented reality content in the camera video content, and displaying video content based on the 3D augmented reality content. The video content is associated with the object.

Systems and methods are described to selectively stream content based on parental control ratings. At a client device, a manifest identifying sequential segments of a media asset and versions of a particular segment of the sequential segments may be received, and a graphical user interface may be generated for display to simultaneously depict a respective portion of each respective version of the particular segment and respective selectable options associated with each respective version of the particular segment. A selection of a first option may be received that is associated with a first version of the particular segment, and during playing of the media asset, in response to determining that the particular segment is the next segment to be played, the first version of the particular segment may be requested from the server.

Display with an appropriate luminance dynamic range is realizable on a receiving side. A gamma curve is applied to input video data having a level range from 0% to 100%*N (N: a number larger than 1) to obtain transmission video data. This transmission video data is transmitted together with auxiliary information used for converting a high-luminance level on the receiving side. A high-level side level range of the transmission video data is converted on the receiving side such that a maximum level becomes a predetermined level based on the auxiliary information received together with the transmission video data.

An apparatus (101) for enabling reproduction of spatial audio signals. The apparatus comprises means for obtaining (401) audio signals (501) comprising one or more channels and obtaining (403) spatial metadata (503) relating to the audio signals (501). The spatial metadata (503) comprises information that indicates how to spatially reproduce the audio signals. The apparatus also comprises means for obtaining (405) information relating to a field of view of video (505) wherein the video is for display on a display (205) of a rendering device (201) and wherein the video is associated with the audio signals (501). The apparatus also comprises means for aligning (407) spatial reproduction of the audio signals based, at least in part, on the obtained spatial metadata (503), with objects (309A, 309B) in the video according to the obtained information relating to the field of view of video; and enabling (409) reproduction of the audio signals based on the aligning (407).

A display device and a control method therefor are disclosed. According to the disclosure, the display device comprises: a sensor for sensing the surrounding environmental state; an inputter for receiving a user command for content conversion; an outputter for outputting content corresponding to the user command; and a processor for controlling the outputter such that screen brightness and/or audio output strength of second content corresponding to the user command is changed and outputted, when the user command is inputted, on the basis of the sensed surrounding environmental state and/or output information of currently outputted first content. Therefore, the display device can variously output an output of content image and/or audio according to the surrounding environmental state.

Systems and methods are provided herein to dynamically update content restrictions for multiple users by detecting a first user in the proximity of a media device playing a first content item and detecting a second user entering the proximity of the media device. In response to detecting a second user entering the proximity of the media device and receiving a command from the first user that controls playing the first content, the system modifies a stored relationship between the first user and the second user to track the relationship between the first user and the second user. Thereafter, when the system detects the first user and the second user in the proximity of a media device playing a second content, in response, the system automatically performs an action that controls the playing of the second content (e.g., without user having to issue those commands).
