SUBTITLE BORDER-CROSSING PROCESSING METHOD AND APPARATUS, AND ELECTRONIC DEVICE
20220248102 · 2022-08-04 ·

A method, an apparatus and an electronic device for processing a subtitle beyond scope are provided. In the method, size information of a display device of a terminal is acquired, where the size information indicates a size of the display device. A secure zone is established according to the size information, where the secure zone has a size less than or equal to the size of the display device. A video frame is selected from video images in response to playing the video images by the terminal. A composite frame is generated using parts of the video frame that are beyond the secure zone. It is judged whether the composite frame contains text. It is determined that a subtitle in the video images is beyond scope if the composite frame contains text.

This application provides a video message generation method and apparatus, an electronic device, and a storage medium. The video message generation method includes: receiving a comment instruction for a video; determining a target frame corresponding to the comment instruction in the video; obtaining input comment content of the target frame; and generating a video message based on the video, the target frame, and the comment content of the target frame.

REPRODUCTION CONTROL OF SCENE DESCRIPTION

A media rendering device and method for reproduction control of scene description is provided. The media rendering device retrieves media content that includes a set of filmed scenes and text information. The text information includes video description information and timing information. The video description information describes a filmed scene in the set of filmed scenes. The media rendering device further extracts the timing information to reproduce the video description information from the text information of the filmed scene. The media rendering device further controls the reproduction of the video description information in either a textual representation or in a textual and audio representation at a first-time interval indicated by the extracted timing information of the filmed scene.

EMBEDDED INDICATORS

An example system including a processor and a memory. The memory resource may store machine-readable instructions to cause the processor to assign a subject state indicator to a pixel to depict a subject in a video frame of a video signal, wherein the subject state indicator is based on a psychophysiological state of the subject to be depicted by the pixel, embed the subject state indicator for the pixel in the video signal, and broadcast the video signal with the embedded subject state indicator for the pixel to a display device.

Method and device for transmitting stereo media content

The invention relates to a method for generating one or more media files, the method comprising: obtaining encoded stereoscopic media data comprising first view frames and second view frames, each first view frame being associated with a second view frame, generating a track comprising the encoded stereoscopic media data, generating descriptive metadata based on which the view frame corresponding to a left view is identified, and generating the one or more media files based on the generated track and the generated descriptive metadata. The invention also relates to a method for processing one or more media files, the method comprising: obtaining the one or more media files, processing the obtained one or more media files to obtain a track comprising encoded stereoscopic media data comprising first view frames and second view frames, each first view frame being associated with a second view frame, and processing the obtained one or more media files to obtain descriptive metadata based on which the view frame corresponding to a left view is identified.

REPRODUCING DEVICE, REPRODUCING METHOD, PROGRAM, AND TRANSMITTING DEVICE
20230396831 · 2023-12-07 · ·

A transmitting apparatus including circuitry configured to generate caption data corresponding to content data and having elements defined in Extensible Markup Language (XML), and output the content data and the generated caption data to a reproducing device.

SYSTEMS AND METHODS FOR LINKING SEGMENTS OF MEDIA GUIDANCE DATA FOR EFFICIENT OPERATION OF MEMORY CONSTRAINED DEVICES

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.

Systems and methods to optimize music play in a scrolling news feed

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.

Adaptive content delivery

Methods and systems for providing and managing content are described. An example method can comprise receiving at least a portion of a content item and determining a timing attribute associated with at least a portion of the content item. An example method can also comprise determining a delivery information attribute based on the timing attribute. The delivery information attribute can comprise at least one of a time duration to process at least a portion of the content item and a time duration to receive or transmit at least a portion of the content item. An example method can also comprise receiving an update to the content item based on the delivery information attribute.

Metadata transcoding

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.
