Abstract: Methods and systems are disclosed for generating video by applying a template to various content items. The methods and systems select, by an interaction application, a video generation template comprising instructions for combining a set of content items into a video using one or more augmented reality (AR) elements. The methods and systems identify a subset of content items from a plurality of previously captured content items and modify one or more content items of the identified subset of content items based on the AR elements of the video generation template. The methods and systems generate a video comprising a collection of content items including the identified subset of content items and the modified one or more content items based on the instructions of the video generation template.

Abstract: Methods and systems are disclosed for applying augmented reality animations to an image. The methods and systems access an image and select an augmented reality (AR) experience to apply to the image, the AR experience comprising one or more AR element animations. The methods and systems repeatedly apply the AR experience to the image over a specified time interval to overlay the one or more AR element animations on the image. The methods and systems generate a video having a duration corresponding to the specified time interval in response to repeatedly applying the AR experience to the image, the video depicting the one or more AR element animations on the image.

Abstract: A method for data transmission, a receiving end, a data source and a computer-readable storage medium are provided. The method may include acquiring a first transmission moment for key data of a newly accessed data source, and a second transmission moment for the key data of a previously accessed data source; generating a new first transmission moment according to the second transmission moment and a preset interval, in response to an interval between the first transmission moment and the second transmission moment being less than the preset interval; where the interval between the new first transmission moment and the second transmission moment is greater than or equal to the preset interval; and sending the new first transmission moment to the newly accessed data source, such that the newly accessed data source transmits the key data to the receiving end according to the new first transmission moment.

Abstract: A method and a compact apparatus to read shift-multiplexed holograms on a storage medium without the need for any lenses, and without the need for moving the storage medium. The shift-multiplexed holograms have centers at different locations. The apparatus can generate an array of diverging spherical waves of reference beams, each for illuminating one of the holograms. Each hologram is read as an image on a detector array by illuminating that hologram with a corresponding diverging spherical wave of reference beam. Different holograms can be read by illuminating the medium with a different diverging spherical reference beam. The diverging beams can be from an array of sources, or can be from switching one source.
