A recognition data creation device includes an image acquirer and a data creator. The image acquirer acquires a plurality of image frames included in a frame sequence that composes video content. Based on an inter-frame change in an image in the plurality of image frames acquired by the image acquirer, the data creator creates recognition data representing the video content, the recognition data to be used as a fingerprint in recognition of the video content.

Methods and system deliver media to users of media presentation systems. In accordance with one embodiment of the invention, a media server communicates with a media presentation system, such as a media player for streaming video and audio, to present subscription and non-subscription media to the user of the media presentation system. Subscription media may include multi-tiered media packages and individual media offerings as selected by the user. The media may be presented in various formats, including video, a graphical display, an audio presentation, a graphical and audio presentation, URL links, and interactive windows. Information about the user, the user's subscription status, the user's media presentation system and information about the media providers and the media offered by the media providers are maintained by the media server. The media server updates the foregoing information in accordance with the interaction between the media server, the users of media presentation systems, and the media providers.

Disclosed herein is a reception apparatus including: a reception block configured to receive broadcast content broadcast via a broadcasting network; an acquisition block configured to acquire inserted content that is inserted in the broadcast content during the reception thereof; an output block configured to output at least one of the broadcast content and the inserted content; a switch block configured to switch between the broadcast content and the inserted content outputted from the output block; and a buffer configured to sequentially store data of the received broadcast content when the broadcast content is switched to the inserted content; wherein, if the inserted content is switched to the broadcast content, the output block outputs the broadcast content from the buffer while the inserted content is outputted.

A method of processing media data. The method includes determining, for a conversion between the media data and a media data file, whether a preselection element includes an indicator, wherein the indicator indicates that video data units representing a target picture-in-picture region of a main video are able to be replaced by corresponding video data units of a supplementary video; and performing the conversion between the media data and the media data file based on the indicator. A corresponding video coding apparatus and non-transitory computer-readable recording medium are also disclosed.

A system processed a representation of a media content item using a trained machine learning model to identify whether the media content item is a modified media content item. The trained machine learning model outputs an indication of one or more modifications of the media content item. Responsive to determining that the one or more modifications satisfy a criterion, one or more operations are performed on the media content item in view of the one or more modifications to generate an updated media content item. The updated media content item is compared to known media content items to identify known material contained therein.

Provided are a same-screen interaction control method, an electronic device and a storage medium. The same-screen interaction control method includes: determining a same-screen interaction receiver who responds to an initiation request; calling a virtual scene template corresponding to the initiation request, and establishing a target virtual scene corresponding to the virtual scene template; acquiring a first key image, and a second key image corresponding to the same-screen interaction receiver; performing splicing processing on the first key image and the second key image by means of the target virtual scene, so as to obtain a same-screen interaction scene, and generating a same-screen live broadcast video stream corresponding to the same-screen interaction scene; and sending the same-screen live broadcast video stream to a server, so as to synchronize the same-screen live broadcast video stream to a live broadcast client by means of the server.
