Subtitles (graphics) can be superimposed and displayed on a video satisfactorily. A container in a predetermined format including a video stream having video data with UHD resolution and a subtitle stream having subtitle data is received. The video data is obtained by decoding the video stream. Bitmap data of the subtitles is obtained by decoding the subtitle stream. In a case where a resolution of the subtitles does not match the UHD resolution, processing of converting a position of the subtitles is performed on the bitmap data of the subtitles. Video data for display is obtained by superimposing, on the video data, the bitmap data of the subtitles on which the processing of converting the position has been performed.

The present document relates to transcoding of metadata, and in particular to a method and system for transcoding metadata with reduced computational complexity. A transcoder configured to transcode an inbound bitstream comprising an inbound content frame and an associated inbound metadata frame into an outbound bitstream comprising an outbound content frame and an associated outbound metadata frame is described. The inbound content frame is indicative of a signal encoded according to a first codec system and the outbound content frame is indicative of the signal encoded according to a second codec system. The transcoder is configured to identify an inbound block of metadata from the inbound metadata frame, the inbound block of metadata associated with an inbound descriptor indicative of one or more properties of metadata comprised within the inbound block of metadata, and to generate the outbound metadata frame from the inbound metadata frame based on the inbound descriptor.

The disclosure provides a method for interactive control of live television broadcast streams. The method includes receiving a streaming live media feed (103) from a television broadcaster (102) and displaying an overlay (212) on media content (M) of the streaming live media feed (103). The overlay (212) includes a play control option unassociated with an intermediary feed source of the live media feed between the television broadcaster and the media device (115). The method further includes receiving a first selection input of the play control option and determining that the selection input corresponds to a play mode at a first location within the media content (M) of the streaming live media feed by determining that a first fingerprint (128, 208, 306) fails to match a second fingerprint (128, 208, 306). Furthermore, the method includes overlaying targeted overlay content on the streaming live media feed.

Aspects described herein include a user display unit that determines a portion of a presentation currently being viewed by a user through a transparent display. For example, if the display area is a theater screen, only a portion of the screen may be viewable to the user through the transparent display. The display unit may display metadata on the transparent display with a spatial relationship to one or more objects in the presentation. For example, the display unit may output a text bubble near an actor in the presentation that provides an interesting fact about the actor which may overlay or occlude the presentation. In one aspect, if the object in the presentation moves or the display unit is reoriented, the display unit may move the metadata to maintain the spatial relationship between the object and the metadata in the transparent display.

Systems, methods, and non-transitory computer readable media are configured to receive metadata for audio content associated with an audio content item for presentation in a news feed to be displayed on a screen of a computing device associated with a user. The metadata is transformed for display in the audio content item. The transformed metadata is displayed in the audio content item. In addition, systems, methods, and non-transitory computer readable media are configured to present an audio content item in a news feed to be displayed on a screen of a computing device associated with a user. An input by the user for scrolling the news feed and the audio content item on the screen is received. A pop out player is presented in response to disappearance of the audio content item from the screen based on the scrolling.

An object is to make it possible to perform caption display satisfactorily in a case where the caption display position is designated as a relative position. The video stream is decoded to obtain video data, and the subtitle stream including the caption information is decoded to obtain bitmap data of the caption. The caption display position in the caption display position information included in the caption information is designated as a relative position with respect to the caption display range. In a case where the aspect ratio of the video area is different from the aspect ratio of the display video area, the caption display position is determined with the display video area defined as the caption display range, further resize processing is performed, and the display position control is performed onto the bitmap data of the caption on the basis of the caption display position that has undergone the resize processing. Bitmap data of the caption that has undergone display position control is superimposed on the video data to obtain display video data.

A video coding for machines (VCM) encoder includes a first video encoder, the first video encoder configured to encode an input video into a bitstream. The VCM encoder includes a feature extractor, the feature extractor configured to detect at least a feature in the input video. The VCM encoder includes a second encoder, the second encoder configured to encode a feature bitstream as a function of the input video and at least a feature.

Systems and methods for optimizing videos are disclosed. A method of the present disclosure includes analyzing a video using a plurality of rules to determine one or more optimizations for the video, the one or more optimizations reflecting a subset of properties to improve viewership statistics of the video by automatically modifying characteristics of the video based on the subset of properties that is indicative of improved viewership statistics pertaining to a plurality of users of a media hosting service, wherein the characteristics comprise at least one characteristic, which when automatically modified, results in a change to the video that correlates to improved viewership statistics pertaining to the plurality of users. The method further includes causing the characteristics of the video to be modified to implement the one or more optimizations, and causing the video with the modified characteristics to be presented to at least a subset of the plurality of users.

Methods and systems for generating segmented media asset identifiers are described herein. The method includes retrieving a first media guidance data segment of a plurality of media guidance data segments. Each segment of the plurality of media guidance data segments includes a plurality of media asset identifiers and is navigationally linked to at least one other media guidance data segment. The method further involves generating for display the media asset identifiers of the first media guidance data segment. While generating for display the media asset identifiers of the first media guidance data segment, a first user input corresponding to navigating to the media asset identifiers of a linked media guidance data segment is received. In response to receiving the first user input, the linked media guidance data segment is retrieved, and the media asset identifiers of the linked media guidance data segment are generated for display.

A method for optimizing an animation file by reducing its size without substantially modifying the quality of the animation as viewed by a user is disclosed. The solution includes assigning a metadata tag to each frame in the animation file and creating a metadata playback file to store a sequence of frames that should be played during playback of the optimized animation file. Each animation frame in the original animation file is then compared to all other previous non-repetitive frames to determine if the current frame is substantially similar to a previous one. When a frame is determined to be substantially similar, it is deleted in the optimized animation file, while a reference to the previous similar frame is included in the sequence of frames stored in the metadata playback file.
