Among other things, videos and commercials are downloaded to a mobile device for storage on the mobile device and later playout on the mobile device. The downloading includes downloading of metadata associated with the commercials and based on which the mobile device can select commercials for insertion into videos being played back to the user of the mobile device. The commercials to be downloaded are selected based on one or a combination of any two or more of the location of the user, the type of mobile device, and personally-identifiable information about a user of the mobile device.

An apparatus comprises a processing unit configured to: obtain image data and metadata of digital image frames captured by a capturing device, the metadata comprising initial time of capture determined in accordance with an internal clock of the capturing device, the at least one digital image frame comprising a reference digital image frame captured of a scene comprising a machine-readable time marking indicating reference time; recognize a reference instant of time on the basis of the image data of the reference digital image frame; determine a time offset between the reference instant of time and the initial time of capture of the reference digital image frame; and adjust the metadata of a digital image frame so as to include corrected time of capture.

Systems and methods can support a data processing apparatus. The data processing apparatus can include a data processor that is associated with a data capturing device on a stationary object and/or a movable object. The data processor can receive data in a data flow from one or more data sources, wherein the data flow is configured based on a time sequence. Then, the data processor can receive a control signal, which is associated with a first timestamp, wherein the first timestamp indicates a first time. Furthermore, the data processor can determine a first data segment by applying the first timestamp on the data flow, wherein the first data segment is associated with a time period in the time sequence that includes the first time.

An omni-directional audio signal acquisition and playback system is disclosed. In some embodiments, the described system includes a set of microphones positioned substantially evenly with respect to a center of the audio signal acquisition environment, the set of microphones are configured to acquire multiple channels of omni-directional audio signals. The system further includes one or more processors configured to: determine current positions of both the left and the right ears of a viewer's head; identify a subset of microphones within the set of microphones which is closest to the current positions of the left and right ears of the viewer's head; and compute a left channel and a right channel of audio output signals using the omni-directional audio signals recorded by the identified subset of microphones. The system also includes a set of audio output devices configured to playback the left channel and the right channel of audio output signals for the left ear and the right ear of the viewer, respectively.

A driving information recording apparatus that records driving information of a vehicle, the apparatus includes: a processor that: (i) associates, as a data file, information related to a driving condition of the vehicle with a driving mode of the vehicle at a time at which the driving condition occurred, and (ii) records the data file in a recording medium having a recording area. Thus, it is possible to provide a preferred technology for recording the driving information of the vehicle that has a switching function of driving modes.

A system for audio object delivery based on audible frequency analysis comprises a network server comprising non-transitory memory storing an application that, in response to execution, the network server: ingests a plurality of audio clip messages that each comprise metadata and an audio clip file. For at least one audio clip message, the network server reduces the audio clip file to a predefined time length, creates a plurality of time bins, determines that a first time bin and a second time bin correspond with a trigger sound frequency, generates a spectral flatness value, determines a frequency band identifier, and appends the generated spectral flatness value and the frequency band identifier to the audio clip message. The network server assigns the appended audio clip message to a voice matrix, identifies user equipment based on the voice matrix, and initiates delivery of an audio object to the identified user equipment.

A method of enabling processing of a video stream is described. The method comprises establishing a slice width for frames of the video stream; receiving the video stream; dividing, for each frame of the video stream, the frame into vertical slices having the slice width; storing a frame of the video stream in a re-ordered slice based format. Computer-readable storage medium and a device for enabling processing of a video stream are also described.

Provided is an image processing device including at least one processor, in which the processor acquires a first performance evaluation value related to performance of a first imaging apparatus of a first user who is one of a plurality of users, acquires a second performance evaluation value related to performance of a second imaging apparatus of a second user different from the first user among the plurality of users, specifies an image of the second user corresponding to the second imaging apparatus having the second performance evaluation value, which is equal to or larger than the first performance evaluation value, from shared images which are limitedly shared by the plurality of users, and sets a presentation priority of a specific image, which is the specified image, to the first user to be higher than presentation priorities of other shared images.

The present invention discloses methods and system of recording and faithfully reproducing sensations in 3D. The parameters of the recording includes the target volume where the cause of all recorded sensation originate, the observation volume where all supported observers are situated and other positions, orientations, and other situations of the observer are specified. The method of recording and reproducing sensations faithfully in 3D with the additional capability of searching for positions and situations in which an observer may feel a specified sensation. The waxel means to support the recording, reproduction and searching.
