Broadcasting signal transmission device, broadcasting signal reception device, broadcasting signal transmission method, and broadcasting signal reception method

A method of processing information in a digital receiver connected to an external input source includes receiving uncompressed data of a broadcast service from the external input source, the broadcast service delivered based on either a Real-Time Object Delivery over Unidirectional Transport (ROUTE) protocol or an MPEG Media Transport (MMT) protocol; extracting an audio watermark from the uncompressed data; making a request to a specific server using domain type and server code of the audio watermark to form a first URL; receiving a recovery file including a second URL used to retrieve signaling files needed to access and present a supplementary content; retrieving the signaling files using the second URL in the recovery file; and presenting the supplementary content based on the signaling files. Further, timing information included in the recovery file is used to synchronize the supplementary content with the uncompressed data from the external input source.

Remote support system and method

A remote support communication system comprises a user terminal unit and an operator terminal unit. Said user terminal unit comprises a camera module configured to shoot video images of an object in order to acquire an ordered sequence of video frames forming a corresponding first video and a video transmission module configured to transmit the video frames to the operator terminal unit. Said operator terminal unit comprises a display and drawing module configured to display the video frames and allow an operator to generate digital graphic components to be superimposed on respective video frames; a graphic transmitter module configured to transmit said graphic components to the user terminal unit. The user terminal unit further comprises a graphic receiver module configured to receive, from the operator terminal unit, the digital graphic components; a display module configured to display a second video based on the video frames and the received digital graphic components; and a synchronization module configured to control the display module to display received digital graphic components superimposed on respective video frames.

An association with a system timing at the time of transmission is secured without changing a display timing in text information of a subtitle, and a reception side displays the subtitle at an appropriate timing. A packet in which a document of the text information of the subtitle having display timing information is included in a payload is generated and transmitted in synchronization with a sample period. A header of the packet includes a time stamp on a first time axis indicating a start time of the corresponding sample period. The payload of the packet further includes reference time information of a second time axis regarding the display timing associated with the start time of the corresponding sample period.

MEDIA ENVIRONMENT DRIVEN CONTENT DISTRIBUTION PLATFORM

A method for a media environment driven content distribution platform includes obtaining synchronization data derived from the content and ancillary data pegged to instants in the synchronization data derived from the content, and communicating the synchronization data derived from the content and the ancillary data pegged to the instants in the synchronization data derived from the content such that subsequent alignment of the synchronization data derived from the content to the content synchronizes the ancillary data pegged to the instants in the synchronization data derived from the content to the content.

Method and apparatus for signaling user interactions on overlay and grouping overlays to background for omnidirectional content

A method, apparatus and computer program product describing groups of overlays, such as semantically correlated overlays, to background media content. In the context of a method, a group of overlays to background media content is defined by metadata (60). The overlays include semantically correlated overlays having alternative overlays representing content with different levels of detail or overlays providing different choices of content. The method also includes receiving client selection of a respective overlay from a group of overlays (62). In response to the client selection, the method causes the respective overlay to be provided. The respective overlay is received (64) for presentation concurrent with background media content (68).

Audio and video processing method and apparatus, terminal and storage medium

An audio and video processing method, includes: displaying a video creation interface of a target audio, where the video creation interface includes n audio clips of the target audio and video recording entries corresponding to the n audio clips respectively, n≥2; receiving a trigger signal acting on a target video recording entry on the video creation interface, where the target video recording entry is a video recording entry corresponding to a target audio clip; acquiring a target video corresponding to the target audio clip based on the trigger signal, where the target video is a video clip of which the video duration is less than a duration threshold; and sending a video creation request carrying the target video to a server, where the video creation request is used to instruct to play picture information of the target video when the target audio is played.

Testing rendering of screen objects
11647249 · 2023-05-09 · ·

The present disclosure relates to methods and devices for testing video data being rendered at or using a media device. A plurality of video frames to be rendered is received, each frame comprising one or more primary screen objects and at least one further screen object. The received frames are rendered at or using the media device wherein the at least one further screen object is superimposed on the one or more primary screen objects of a given frame during rendering. The rendered frames are provided to a data model. Extracted metadata indicating the presence or absence of further screen objects in the rendered video frames is the output of the data model. The data model is also provided with original metadata associated with the video frames prior to rendering. The rendering of each further screen object is then tested based on the original metadata and extracted metadata relating to a given video frame. The disclosure also extends to associated methods and devices for generating training data for testing rendering of video frame and training a data model using the training data.

Method for Synchronizing Additional Signal to Primary Signal
20230137315 · 2023-05-04 · ·

The present invention relates to a method for synchronizing an additional signal to a primary signal. Synchronization information for a primary signal is generated by extracting at least one signal feature sequence of the primary signal and comparing it to DB feature sequences stored in a database. If the signal feature sequence matches one of the DB feature sequences to a predetermined degree, then synchronization information of the matching DB feature sequences is allocated to the primary signal at a position specified by the signal feature sequence. The synchronization information is transmitted to a playback device, which outputs an additional signal to the primary signal based on the synchronization information.
