  • Patent number: 10412425
    Abstract: In one embodiment, a method includes receiving a series of a series of audio-and-video segment pairs in a live video feed. The series of audio-and-video segment pairs is traversed, comparing the end-time of a current audio-and-video segment with the start-time of the next audio-and-video segment pair, in the sequence, and identifying any time gap between consecutive audio-and-video segment pairs. When a time gap is identified, the end-time of a current segment pair is subtracted from the start time of the next segment-pair to define an offset time, and subsequent start times of segment pairs in the sequence are adjusted based on this offset time. If after adjusting a start time of the next segment-pair by the offset time, a gap in the audio segment remains, then the gap is filled with an encoded silence sequence.

  • Patent number: 8417094
    Abstract: A recording apparatus of this invention detects the state of management information, which pertains to a recording address of an image signal, and which is reproduced from a disk-like recording medium having a first area for the image signal and a second area for the management information. On the basis of the detection result, management data is reproduced from the first area of the disk-like recording medium. On the basis of the management data reproduced from the first area, the management information reproduced from the second area is modified. A modify unit records the modified management information in the second area.

  • Patent number: 8355029
    Abstract: According to one aspect, the invention provides an apparatus for converting data encoded in a graphics signal to at least one output signal. The apparatus includes an input, a plurality of outputs, signal processing circuitry and a controller. The input is adapted to receive the graphics signal where the graphics signal includes a plurality of frames generated at least in part from original data. The signal processing circuitry is adapted to locate, in the graphics signal, data corresponding to the original data, convert the data corresponding to the original data to output data and communicate the output data to the plurality of outputs. The controller is adapted to monitor a capacity of the signal processing circuitry and generate a signal that results in at least one disposable frame being added to the plurality of frames. The signal processing circuitry is adapted to discard the at least one disposable frame.

  • Patent number: 8320748
    Abstract: An audio/video information recording/reproducing device capable of easily implementing a post-recording function on an optical disk by using even a low-cost disk drive having a comparatively low-speed seek time. When recording a video file, it is recorded on an optical disk continuously for a duration equivalent to more than three times a seek time. When recording dubbing audio, it is recorded continuously only with constant data size at the same time with the reproducing of the recorded video file, thereby enabling concurrent real-time continuous reproducing and recording. Accordingly, concurrent reproductions of a video file and an audio file are ensured when reproducing dubbing audio.
