20140369425 | ELEMENTARY STREAM MULTIPLEXING METHOD, MULTIPLEXING SYSTEM, ENCODING OR DECODING METHOD AND APPARATUS - At the time of an encoding process, a video elementary stream is generated and output by capturing and encoding a video image signal at a time interval of a video frame synchronous with a timing of a video synchronization signal, and an audio elementary stream is generated by capturing and encoding an audio signal at each audio interval. An audio packetized elementary stream where one packet has a stream length corresponding to the time interval of the video frame is multiplexed with the audio elementary stream, and the stream is output. | 12-18-2014 |
20150235668 | VIDEO/AUDIO SYNCHRONIZATION APPARATUS AND VIDEO/AUDIO SYNCHRONIZATION METHOD - A video/audio synchronization apparatus includes: a decoder configured to decode a frame contained in encoded video data and determine playback time of the frame based on a first clock signal, and decode encoded audio data and determine playback time of an associated audio signal contained in the decoded audio data and to be played back simultaneously with the frame, based on a second clock signal different from the first clock signal; a silent period detector configured to detect a silent period from within the associated audio signal; and an audio timing adjuster configured to reduce a difference between the playback time of the frame and the playback time of the associated audio signal by skipping or repeating a silent period contained within a period of the associated audio signal. | 08-20-2015 |
20150264346 | VIDEO ENCODING DEVICE AND VIDEO ENCODING METHOD - A video encoding device includes: a processor configured to execute a process including: when successively encoding a plurality of blocks obtained by dividing a frame image in a predetermined period, selecting an encoding mode by which each block is encoded, in accordance with a progress status of encoding of the blocks; and successively encoding each block of the frame image in the selected encoding mode. | 09-17-2015 |
20160127739 | MOTION SEARCH PROCESSING METHOD AND DEVICE - A motion search processing method includes: dividing, by a computer, first image data included in video data in accordance with a frequency band and generating a plurality of pieces of divided image data; performing compression processing on first divided image data among the plurality of pieces of divided image data and generating compressed divided image data, the first divided image data including a frequency component of which a frequency band is equal to or more than a value; performing first motion search processing on the video data by using second divided image data among the plurality of pieces of divided image data, the second divided image data including a frequency component of which a frequency band is less than the value; and generating second image data by using the plurality of pieces of divided image data and performing second motion search processing by using the second image data. | 05-05-2016 |
