Systems and methods are disclosed for a holographic streaming management system. In one implementation, a first media content item is received. Metadata tag(s) are associated with the first media content item. Based on one or more metadata tag(s), the first media content item is selected for presentation at a first holographic presentation device. The selected first media content item and a content presentation file associated with the first holographic presentation device are transmitted to the first holographic presentation device. Input(s) corresponding to a presentation of the first media content item via the first holographic presentation device are received. Based on the received input(s), aspect(s) of a transmission of a second media content item to the first holographic presentation device are adjusted.

A mark corresponding to recording data is formed on an optical disk by: encoding the recording data in accordance with a modulation code and generating encoded data; classifying the encoded data by a combination of at least two of a mark length of a mark, a space length of a preceding space, the mark length of a preceding mark, and the space length of a succeeding space; setting a correction amount for adjusting the position of the start edge and the end edge of a recording pulse based on an evaluation index of a decoding result, which is a result of decoding a reproduction signal of the encoded data, for each of the classification; and generating the recording pulse corresponding to the encoded data by using the correction amount corresponding to the classification of the run length of the encoded data.

A method for cooperatively collecting video data from driving recorders includes steps of: by a driving recorder serving as a requesting device, broadcasting a video request; by another driving recorder serving as a cooperative device, generating a video file in response to receipt of the video request, encrypting the video file to result in an encrypted file, and transmitting the encrypted file to a video file server; by the video file server, decrypting the encrypted file to result in the video file, storing the video file, and sending a success notification of video data collection to a user device based on contact information contained in pre-stored registration data.

A method, apparatus and computer-readable storage medium are provided to define a storyline based on path probabilities for a plurality of paths through the frames of a video. Relative to a method and for a plurality of frames of a video, regions of a first frame and regions of a second, subsequent frame that have been viewed are identified. tified. For each of at least one first-frame region of one or more regions of the first frame, the method determines a transition probability of transitioning from a respective first-frame frame region of the first frame to each of at least one second-frame region of a plurality of regions of the second frame. Based on the transition probabilities, the method determines a path probability for each of at least one of a plurality of paths through the frames of the video. The method additionally defines a storyline based on the path probabilities.

An apparatus according to one approach includes a module having an array of transducers having at least two transducers. The apparatus also includes a persistent memory having stored therein data of a span of the array of transducers at a particular temperature. An apparatus according to another approach includes a module having fiducials at known positions relative to an array of transducers. The apparatus also includes a persistent memory having stored therein data of a span between the fiducials at a particular temperature. The fiducial span may be used in conjunction with the known locations of the fiducials relative to the array to characterize the span of the array.

A computer-implemented method overlays an alert over a pre-recorded video regarding an upcoming segment of the pre-recorded video. One or more processors receive a pre-recorded video that is directed to a main topic, and then partition the pre-recorded video into sub-topic segments, where each sub-topic segment is about a sub-topic of the main topic. The processor(s) identify previous entities' responses while previous entities viewed precursory sub-topic segments from the pre-recorded video, where the precursory sub-topic segments were presented before an upcoming sub-topic segment. The processor(s) receive a current entity's responses that occurred while a current entity viewed one or more of the precursory sub-topic segments from the pre-recorded video, then compare the current entity's responses to the previous entities' responses. In response to the responses matching, the processor(s) overlay an alert over the pre-recorded video advising the current entity that the upcoming sub-topic segment will be difficult to understand.
