| 20080310823 | VIDEO PROCESSING APPARATUS AND CONTROL METHOD THEREOF - A video processing apparatus, includes: a signal input unit which receives a broadcasting signal; a signal processing unit which processes the broadcasting signal received by the signal input unit; and a control unit which determines whether a virtual channel table which comprises language information exists in additional information which is included in the received broadcasting signal, and, if it is determined that the virtual channel table exists, controls the signal processing unit to process the broadcasting signal based on the language information of a same packet identification in the virtual channel table as a packet identification of a packet which comprises audio information in a program map table which exists in the additional information. | 12-18-2008 |
| 20090103896 | METHOD AND SYSTEM FOR AUTOMATIC ANNOUNCER VOICE REMOVAL FROM A TELEVISED SPORTING EVENT - A method of automatic announcer voice removal from a televised sporting event. A sound processing circuit divides an audio input signal of a televised sporting event into multiple audio segments. The audio input signal includes crowd noise and announcer commentary. If an audio segment does not exceed a pre-defined amplitude threshold, a voice removal utility adds the audio segment to a recent crowd noise library and stores the segment in an output buffer. If the amplitude of a segment exceeds the threshold, the utility adds the segment to a recent announcer voice library. The sound processing circuit generates an attenuated version of the segment and blends the attenuated version with one or more mixed segments from the recent crowd noise library. The voice removal utility stores the attenuated and blended segment in the output buffer and outputs one or more audio segments from the buffer in a chronological order. | 04-23-2009 |
| 20090175596 | PLAYBACK APPARATUS AND METHOD - A playback apparatus for playing back video information, audio information, and subtitle information from a recording medium, the recording medium having recorded thereon video information, audio information associated with the video information, and subtitle information corresponding to utterance information included in the audio information, the utterance information and the subtitle information being given in a plurality of languages, includes a mode switching unit that switches between a normal playback mode and a language-learning playback mode, and a control unit that, when the language-learning playback mode is set, plays back video information and audio information associated with the video information and reads, from the recording medium, subtitle information given in the same language as a language of utterance information included in the audio information to be played back to perform playback in which subtitles based on the subtitle information are superimposed and displayed on video based on the video information. | 07-09-2009 |
| 20100183284 | OPTICAL DISK DEVICE - An optical disk device includes a reproduction component, an output component and a control component. The reproduction component directs a laser beam at an optical disk that is loaded in the optical disk device with the optical disk storing a plurality of audio data streams in a plurality of different acoustic qualities. The reproduction component reproduces one of the audio data streams. The output component outputs the one of the audio data streams to an amplifier. The control component acquires from the amplifier first audio format information indicating audio formats to which the amplifier corresponds, and acquires from the reproduction component second audio format information indicating audio formats of the audio data streams stored in the optical disk. The control component determines the one of the audio data streams with an audio format that belongs to both the first audio format information and the second audio format information. | 07-22-2010 |
| 20100260483 | SYSTEMS, METHODS, AND APPARATUS FOR RECORDING MULTI-DIMENSIONAL AUDIO - Certain embodiments of the invention may include systems, methods, and apparatus for recording three dimensional audio. According to an example embodiment of the invention, the method may include orienting a three-dimensional (3-D) microphone with respect to a predetermined spatial direction, selectively receiving sounds from one or more directions corresponding to directional receiving elements, recording the selectively received sounds in a 3-D recorder having a plurality of recording channels, recording time code in at least one channel of the 3-D recorder; and mapping the recorded channels to a plurality of output channels. | 10-14-2010 |
| 20100272417 | STEREOSCOPIC VIDEO AND AUDIO RECORDING METHOD, STEREOSCOPIC VIDEO AND AUDIO REPRODUCING METHOD, STEREOSCOPIC VIDEO AND AUDIO RECORDING APPARATUS, STEREOSCOPIC VIDEO AND AUDIO REPRODUCING APPARATUS, AND STEREOSCOPIC VIDEO AND AUDIO RECORDING MEDIUM - The object of the present invention is to provide a stereoscopic video and audio recording method, a stereoscopic video and audio recording medium, a stereoscopic video and audio reproducing method, a stereoscopic video and audio recording apparatus, and a stereoscopic video and audio reproducing apparatus. An audio information storage region for three-dimensional video is arranged in advance, separately from audio information for ordinary two-dimensional video, in a media recording format for recording stereoscopic video and audio. Therefore, when stereoscopic reproduction is selected, an audio can be reproduced with realistic sensation in a depth direction in sound-image processing or surround processing. | 10-28-2010 |
