Abstract: A moving image reproducer includes a generation section, a calculation section, a determination section, a correction section and a control section. The generation section generates an interpolation frame image interpolating between two adjacent frame images among a plurality of frame images. The calculation section sequentially calculates a progress level of a predetermined musical piece between the two adjacent frame images reproduced in synchronization with the predetermined musical piece. The determination section determines whether the progress level has varied along with a change in a tempo of the predetermined musical piece defined in the tempo information. The correction section corrects the progress level so as to reduce the variation in the progress level along with the change in the tempo if the progress level is determined to have varied. The control section controls the generation section to generate an interpolation frame image corresponding to the corrected progress level.

Abstract: The present disclosure involves a method of managing media playback. The method includes displaying a media program on a touch screen of an electronic device. The method includes detecting, via the touch screen, an input from a user indicating that the user wishes to fast forward or rewind the media program. The method includes triggering, in response to the detected input from the user, an appearance of a scroll bar including an indicator on the touch screen. The indicator is configured to be moved along the scroll bar. A length of the scroll bar represents a predefined amount of time that is a fraction of a total duration of the media program. A position of the indicator relative to the scroll bar corresponds to a time location of the media program.

Abstract: A method for previewing and retrieving a video is disclosed. The method includes: (101) setting a variable-length buffer sequence; (102) acquiring and processing a video file to obtain images; (103) detecting scene shots in the obtained images and key frames of the scene shots, and storing the detected scene shots and key frames into the variable-length buffer sequence; and (104) acquiring the scene shots and key frames from the variable-length buffer sequence, matching and comparing the scene shots and key frames with a specified target image to perform image retrieval. A mobile terminal for previewing and retrieving a video is further disclosed. With the technical solution, content preview and fast retrieval of a video file are achieved in a mobile terminal with relatively limited processing capacity and memory resources.

One embodiment of a multimedia file in accordance with the present invention includes a series of encoded video frames and encoded menu information.

Abstract: Identification of starting and ending times of commercial breaks and commercials within those commercial breaks found in audiovisual content is disclosed. A solution to a “batch optimization” problem is used in which commercial locations within a set of audiovisual content are detected as a group by choosing a set of commercial locations which optimizes a cost function which can include considerations of, for example, 1) one or more cues, 2) relative locations of commercials within the audiovisual content, and/or 3) probability models based on statistics obtained regarding characteristics of typical commercial and commercial breaks. Optimization can be done over the total set of commercial location decisions, rather than on a per-commercial basis. Additionally, the cost function can be iteratively evaluated and many more types of cues and combinations of cues can be used in detection of commercials.

Abstract: Video content from a layer of multiple multimedia content layers may be moved to a lowest content layer. The region of the multimedia content layer that previously contained the video content may be replaced with a transparent region. Additional layers that exist between the layer from which the video content was removed and the lowest layer may likewise have corresponding regions replaced with transparent regions. The content layers may be composited together at a display time. Accordingly, the video content of the lowest content layer may be viewed through the transparent regions, which may allow the video to be seen as originally authored. The lowest content layer may be rendered independently of other layers. In some embodiments, the content layer containing video may be performed with dedicated hardware (e.g., a GPU).

Abstract: Hierarchically-encoded video image data and audio data associated with a predetermined encoded layer of the hierarchically-encoded video image data are received, and the audio-associated encoded layer with which the audio data is associated is specified from among a plurality of encoded layers of the hierarchically-encoded video image data. Then, the ratio of the field of view of a decoded video image of an encoded layer to be played back to the field of view of a decoded video image of the audio-associated encoded layer is calculated. A prestored audio correction amount is multiplied by the calculated ratio, and the resulting new audio correction amount is used to correct the audio data.
