A display apparatus and a controlling method thereof provides an optimal viewing environment to a user by differently applying image processing parameters related to image processing time according to content types of input images.

A display apparatus according to an embodiment includes an input interface receiving an input image; and a controller configured to determine an image processing parameter based on characteristics of the input image, and control an image processing time for the input image to be determined in response to the determined image processing parameter.

Disclosed is a display method, including: decoding an input signal comprising an audio signal and a video signal, and identifying a resolution of the decoded video signal; in response that the video signal has an 8K resolution, outputting the video signal to an back end for processing through a first interface, and outputting an on-screen display adjustment signal to the back end for processing through a second interface; in response that the video signal has a 4K or 2K resolution, preprocessing outputting the video signal to the back end for processing through the second interface, and outputting the OSD signal generated by the SoC to the back end for processing through the first interface; and mixing and coding the video signal and the OSD signal, and outputting the mixed and coded signals to a screen for display.

In some embodiments, a method receives playback information for a plurality of representations based on one or more videos being played at a media player. The plurality of representations have at least one different characteristic that affects playback of the video. A dropped-frame measurement is predicted for the plurality of representations based on the playback information. Then, the dropped-frame measurement is compared to a threshold for the plurality of representations. The method marks a first set of the plurality of representations as not being available based on the comparing. A second set of the plurality of representations are provided to the media player when the media player requests a video for playback and the first set of the plurality of representations for the video are blocked from being requested by the media player.

A technique for generating encoded video in a client-server system is provided. According to the technique, a server determines that reprojection analysis should occur. The server generates reprojection metadata based on suitability of video content to reprojection. The server generates encoded video based on the reprojection metadata, and transmits the encoded video to a client for display. The client reprojects video content as directed by the server.

Systems and methods are disclosed herein for presenting subtitle data during media asset fast-access playback operations. Specifically, the system may detect initiation of a fast-access playback operation during playback of a media asset and identify consecutive frames to be displayed during the fast-access playback operation that have associated subtitle data. The system may combine the subtitle data associated with the consecutive frames into a display arrangement and generate for display, with each consecutive frame, instead of the associated subtitle data, the display arrangement.

Multiple video segments may be obtained from a repository of video segments. A selection of a video segment from the multiple video segments may be received. The selected video segment may be presented at a first resolution via a display. A selection of a point in time during presentation of the video segment may be received to extract a frame set from the video segment at or near the selected point in time. The frame set may include multiple frames, including one frame corresponding to the selected point in time, and other frames that correspond to points in time adjacent to the selected point in time. A selection of a single frame within the frame set may be received. The single frame may be received having a second resolution. The second resolution may be higher than the first resolution. The single frame may be presented via the display.

A computing system identifies a media stream being received by a client, based on fingerprint matching conducted with query fingerprints generated by the client at a frame rate. The computing system then causes the client to increase the frame rate, in order to facilitate establishment by the computing system of synchronous lock between true time within the media stream and client time according to a clock of the client. The computing system then uses the established synchronous lock as a basis to map a true-time point at which a content revision should be performed in the media stream to a client-time point at which the client should perform the content revision. And the computing system causes the client to perform the content revision at the determined client-time point.

The present disclosure provides a method and apparatus for automatically synchronizing a first stream of media data with a second, and outputting a third by decoding the streams into channels, splitting the channels into a plurality of piecewise segments defined by control points that the control points with the same index are to be synchronized in time across all the channels, automatically and intelligently adjusting the length of the media data in each segment in an optimal and hybrid manner using a linear or non-linear digital signal processing algorithm, synchronizing and mixing all the processed segments, and outputting the final mixed and encoded data stream. Specifically, one of the media data is video and the other is audio or a translation voice in a different language. With a controlled minimized distortion, one can achieve faster post-processing speed and optimal synchronization quality, therefore save both time and cost for video language localization services.

Multiple video segments may be obtained from a repository of video segments. A selection of a video segment from the multiple video segments may be received. The selected video segment may be presented at a first resolution via a display. A selection of a point in time during presentation of the video segment may be received to extract a frame set from the video segment at or near the selected point in time. The frame set may include multiple frames, including one frame corresponding to the selected point in time, and other frames that correspond to points in time adjacent to the selected point in time. A selection of a single frame within the frame set may be received. The single frame may be received having a second resolution. The second resolution may be higher than the first resolution. The single frame may be presented via the display.

Disclosed are a method for displaying projection picture and a method for rotating projection picture, comprising following steps: A: using a main control chip of a display to receive a picture signal parameter of a handheld terminal; B: the main control chip determining the black edge and calculating the starting position of a display picture by detecting the intensity of display signal inputted from the handheld terminal; C: obtaining the width of the display picture by calculation, and at the same time, directly obtaining the height of the display signal by signal detection of the main control chip; and D: using the function calculation provided by a control unit to enlarge the picture to a proportional or full-screen output with the handheld terminal. After adopting the above method, the display provides a picture with full screen without having black edges or small black edges to enhance the visual experience.
