An image processing device includes: a subtitle information acquisition unit configured to acquire subtitle information; a subtitle processing unit configured to perform rendering of subtitles with a resolution of an entire image of a display panel on the basis of the subtitle information acquired by the subtitle information acquisition unit to generate a subtitle image of a corresponding area among a plurality of display areas divided in the display panel; a corresponding image generation unit configured to generate an image signal of the corresponding area; and a combination unit configured to combine the subtitle image generated by the subtitle processing unit with the image signal generated by the corresponding image generation unit to generate an image signal with subtitles.

Illustrative embodiments include a method, an electronic device, and a computer program product for video processing. In the method, a first group of image frames in a first video having a first resolution is converted into a second group of image frames having a second resolution, the first resolution being higher than the second resolution; a second video having the second resolution is generated based on the second group of image frames; conversion parameters for the second video are determined based on the first group of image frames and the second group of image frames, the conversion parameters being used to convert an image frame in the second group of image frames into an image frame having a third resolution, and the third resolution being higher than the second resolution; and the conversion parameters and the second video are sent to a requester of the first video.

The present invention enables a receiving side to easily recognize a high-quality format corresponding to encoded image data included in an extended video stream. Two video streams including a basic video stream including encoded image data of basic format image data, and an extended video stream including encoded image data of high-quality format image data of one type selected from a plurality of types are generated. A container of a predetermined format including the basic video stream and the extended video stream is transmitted. Information indicating a high-quality format corresponding to the encoded image data included in the extended video stream is inserted into the extended video stream and/or the container.

A method and mobile terminal for processing data are disclosed. The method can include displaying a live streaming page, the live streaming page including a file sharing interface for guiding an anchor to select a file for sharing during live streaming; displaying a file list in the case that the file sharing interface is triggered; acquiring a target file selected from the file list; generating second live streaming data based on the target file, and displaying first live streaming data and the second live streaming data on the live streaming page; and synchronizing the first live streaming data and the second live streaming data to a second mobile terminal, wherein the first live streaming data is acquired by a camera of the first mobile terminal, and the second mobile terminal is an audience terminal.

In some embodiments, a method receives a manifest presentation description for a media presentation. The manifest presentation description includes an opportunity that requires resolution to determine supplemental content for the opportunity. A request to resolve the opportunity is sent where information for the supplemental content that is received from the request is inserted in an instance of the media presentation description. The method stores the information for the supplemental content in association with an identifier for the opportunity. An update to the manifest presentation description is received where the update includes the opportunity. The method retrieves the information for the supplemental content that was stored in association with the identifier for the opportunity and inserts the information for the supplemental content into the instance of the update to the manifest presentation description.

A stream playout and distribution system and method for disparate live media output stream playout and broadcast distribution are provided. The system generates a plurality of disparate live media output stream manifests, which comprises at least one of an index of a plurality of pre-encoded media assets or a plurality of live input streams, based on playout schedule and content viewing demographics. The system further generates a new version of at least one disparate live media output stream manifest based on insertion of a segment of at least one of a pre-encoded media asset or a live input stream into the disparate live media output stream manifest. Each segment corresponds to a different quality level and a different content encryption mode. The system further retrieves one or more broadcast content segments encoded in first encoding format of the new version, and converts retrieved broadcast content segments to second encoding format.

A stream playout and distribution system is provided for disparate live media output stream playout and broadcast distribution. The system generates a new version of a disparate live media output stream manifest based on insertion of a plurality of segments of at least one of a pre-encoded media asset or a live input stream into the disparate live media output stream manifest. Each segment of the plurality of segments corresponds to a different quality level and a different content encryption mode. The plurality of segments corresponds to broadcast content segments encoded in a first encoding format of the new version of the disparate live media output stream manifest. The system converts the broadcast content segments encoded in the first encoding format to a second encoding format in accordance with a broadcasting protocol.

A method and mobile terminal for processing data are disclosed. The method can include displaying a live streaming page, the live streaming page including a file sharing interface for guiding an anchor to select a file for sharing during live streaming; displaying a file list in the case that the file sharing interface is triggered; acquiring a target file selected from the file list; generating second live streaming data based on the target file, and displaying first live streaming data and the second live streaming data on the live streaming page; and synchronizing the first live streaming data and the second live streaming data to a second mobile terminal, wherein the first live streaming data is acquired by a camera of the first mobile terminal, and the second mobile terminal is an audience terminal.
