An apparatus generates an image file including a first region storing a plurality of instances of image data and a second region storing metadata. The metadata includes group information that groups image data shot synchronously with respect to time, the group information indicating image data belonging to a group, and indicator information that indicates an indicator of grouping for the group. The apparatus sets a reference indicating whether the image data has been shot synchronously with respect to time, determines whether the image data has been shot synchronously with respect to time, configures the group information grouping the image data to have been shot synchronously with respect to time, configures the indicator information including at least information of the reference, and generates the file storing the plurality of instances of image data, the group information, and the indicator information.

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium that provides an enhanced synchronization framework. One of the methods includes a primary and a second device that receive configuration information which identifies one or more actions to be performed by the secondary device when it receives specified pulses of a sequence of pulses from the primary device. The primary device transmits a sequence of pulses. The primary and the secondary device receive a particular pulse from the sequence of pulses. The secondary device determines whether the particular pulse satisfies one or more predetermined criteria and generates an instruction based on the determination.

A method includes: via a user interface of a hub device, receiving a first set of user credentials associated with a first operator, the hub device connected to a set of mobile devices; accessing a first operator schedule defining a first scheduled manufacturing operation and a first observer of the first scheduled manufacturing operation, the first observer characterized by a first set of observer credentials; detecting disconnection of a first mobile device in the set of mobile devices from the hub device, the first mobile device associated with a first device ID; in response to detecting disconnection of the first mobile device from the hub device, associating the first device ID with the first operator; and routing a first video feed from the first mobile device to the first observer based on the first device ID and the first set of observer credentials.

A method is disclosed including setting, at a server, a server VSYNC signal to a server VSYNC frequency. The server VSYNC signal corresponding to generation of video frames during frame periods for the server VSYNC frequency. The method including setting, at a client, a client VSYNC signal to a client VSYNC frequency. The method including sending compressed video frames from the server to the client over a network using the server VSYNC signal, wherein the compressed video frames are based on the generated video frames. The method including decoding and displaying, at the client, the compressed video frames. The method including analyzing the timing of one or more client operations to adjust the relative timing between the server VSYNC signal and the client VSYNC signal, as the client receives the compressed video frames.

Methods and devices are provided for adding lyrics to a short video. The device obtains a music material required by the short video and obtains a first playback duration of the short video. The device obtains a target music material having a playback duration matching the first playback duration. The device obtains a lyric sticker corresponding to the target music material based on the lyrics extracted from the target music material and displays a processed short video after adding with the lyric sticker.

A communication apparatus includes a requester unit configured to issue a request for transmission of a packet, a transfer unit configured to transfer the packet based on the request, a transmission unit configured to transmit the packet transferred by the transfer unit and to output a timestamp based on the transmission of the packet, and a control unit configured to control output of a tag associating the packet with the timestamp based on predetermined information that is read from an interface between the transfer unit and the transmission unit.

This system includes an olfactory display in which a plurality of aroma source cartridges can be loaded, a terminal device that controls the olfactory display, and a server connected to the terminal device via a network. The terminal device includes a content reproducer that reproduces an aroma-added content downloaded from the server. Aroma reproduction information includes aroma numbers standardized to specify types of aromas. The content reproducer determines which one of the plurality of aroma source cartridges loaded in the olfactory display is to be used to reproduce an aroma based on the aroma number, and allows the aroma to be emitted from the olfactory display based on the aroma reproduction information in synchronization with video and/or sound.
