CPC Class H04N

In a system and a method for locating a mobile noise source, a sound sensing device catches a sound wave of the mobile noise source, and generates and stores a current sound characteristic information corresponding to the sound wave. An image pickup device catches an image of the mobile noise source, and generates and stores an entry of current image data corresponding to the mobile noise source. A spectrogram and image database stores entries of default spectrogram data and entries of default image data. An information processing unit compares the current sound characteristic information with the entries of default spectrogram data, and stores and associates the current sound characteristic information with the mobile noise source in the spectrogram and image database if no similarity between the current sound characteristic information and the entries of default spectrogram data reaches a preset value.

Provided are methods and systems for variable speed playback. In one aspect the disclosure provides for receiving content having a first playback speed, determining a second playback speed for at least a portion of the content based on a playback factor, associating the second playback speed with the portion of the content, and providing at least the portion of the content at the second playback speed to a display device.

Systems and methods provide for advanced video editing techniques using sampling patterns. In one example, a computing device can receive a selection of a clip of a video and a sampling pattern. The computing device can determine a respective number of frames to sample from the clip for each interval of time over a length of time for a new clip. For example, the computing device can determine a function corresponding the pattern that relates time and the number of frames to sample, a histogram corresponding to the pattern, or a definite integral corresponding to the pattern, among other approaches. The computing device can extract these numbers of frames from the clip and generate the new clip from the extracted frames. The computing device can present the new clip as a preview and send the new clip to other computing devices.

Disclosed herein are computer-implemented method, system, and computer-readable storage-medium embodiments for implementing template-based excerpting and rendering of multimedia performances technologies. An embodiment includes at least one computer processor configured to retrieve a first content instance and corresponding first metadata. The first content instance may include a first plurality of structural elements, with at least one structural element corresponding to at least part of the first metadata. An embodiment may further include selecting a first template comprising a first set of parameters. A parameter of the first set of parameters may be applicable to the at least one structural element. Applicable parameter(s) of the first template may be actively associated with the at least part of the first metadata corresponding to the at least one structural element. The first content instance may be transformed by a rendering engine running on the at least one computer processor.
