Patent number: 9060094Abstract: Individual adjustment of audio volume and video properties in a computer network conference environment is provided. For audio adjustment, a buffer collects incoming streams; a stream decoder decodes the buffered audio streams, a gain adjustment applies a gain increase or decrease to the individual audio stream, and a mixer combines each of the individual signals together. The gain adjustment module receives input from a user interface control associated with each participant, and adjusts the volume of that participant's stream accordingly. If a requested increase in gain would cause an overflow of the signal, only a gain increase that will avoid such overflow is applied. Video properties such as brightness, contrast and saturation are also adjustable. Properties of the user's transmitted audio and video streams are also adjustable.Type: GrantFiled: May 30, 2008Date of Patent: June 16, 2015Assignee: Optical Fusion, Inc.Inventor: Mukund Thapa

Patent number: 8311233Abstract: A multi-channel audio system having multiple loudspeakers is used to obtain information on the location of one or more independent noise sources within an area covered by the loudspeakers. Within the multi-channel audio system, an audio output device has an input for coupling to and receiving audio signals from one or more audio sources; an audio processing module for generating a audio drive signals and providing them on respective outputs to a number of loudspeakers. A sensing module has inputs connected to respective outputs of the audio processing module, for receiving signals corresponding to sound sensed by the loudspeakers. The sensing module includes a discriminator for discriminating between signals corresponding to the audio drive signals and sensed signals from an independent noise source within range of the loudspeakers. A position computation module determines a two or three dimensional position of each independent noise source sensed, relative to the loudspeakers.Type: GrantFiled: November 30, 2005Date of Patent: November 13, 2012Assignee: Koninklijke Philips Electronics N.V.Inventor: John Kinghorn

Patent number: 8265298Abstract: A hands-free loudspeaker system which is capable of achieving high-quality voice amplification without requiring a human speaker to move to a microphone or a microphone to be moved to a human speaker. A microphone whose input level has continued to be above a threshold value for not shorter than a predetermined time period is detected, based on input signals from dispersedly arranged microphones. An input signal from the microphone is selected and outputted to a loudspeaker at an output level or with a delay time, according to a location of the loudspeaker. A preset lowest threshold level is initially set to the threshold value, and an input level of the microphone higher than the threshold value is newly set to the same, while when the input level is lower than the threshold value, a lower value is set to the same in a step-by-step manner.Type: GrantFiled: February 12, 2010Date of Patent: September 11, 2012Assignee: Yamaha CorporationInventors: Atsuko Ito, Akira Miki, Shinichi Sawara

Patent number: 8243977Abstract: An exemplary media player system includes a media player and an earphone. The earphone includes a first earpiece, a second earpiece, a primary volume control unit, and a secondary volume control unit. The first earpiece and the second earpiece are configured for receiving first channel audio signals and second channel audio signals respectively, and converting the audio signals to yield audible sounds. The primary volume control unit adjusts the volume levels of the first earpiece and the second earpiece simultaneously. The secondary volume control unit adjusts the volume of sounds outputted from one of the first earpiece and the second earpiece.Type: GrantFiled: June 27, 2008Date of Patent: August 14, 2012Assignees: Hong Fu Jin Precision Industry (ShenZhen) Co., Ltd., Hon Hai Precision Industry Co., Ltd.Inventors: Lung Dai, Wang-Chang Duan, Bang-Sheng Zuo

Patent number: 8217251Abstract: An interactive assembly for displaying a sequence of words from a text comprising: a processor; at least one memory operatively connected to the processor; at least one speech recognizer operatively connected to the processor; at least one audio input operatively connected the speech recognizer; at least one display operatively connected to the speech recognizer for displaying words of a song based upon the words recognized by the speech recognizer; whereby based upon a word received by the audio input, the next words to be recited incrementally displayed onto the at least one display contemporaneously with the input received from the operator. A method for interactively display the words of a text sequentially on a display comprising: receiving an inputted vocal input in an audio input device; inputting the inputted vocal input into a speech recognizer; comparing the inputted vocal input with words stored in sequence in memory; outputting on a display screen only the next sequential words for display.Type: GrantFiled: September 28, 2009Date of Patent: July 10, 2012Inventor: Lawrence E Anderson

Patent number: 8208646Abstract: In one of many possible embodiments, a method includes providing an audio output signal to an output device for broadcast to a user, receiving audio input, the audio input including user voice input provided by the user and audio content broadcast by the output device in response to receiving the audio output signal, applying at least one predetermined calibration setting, and filtering the audio input based on the audio output signal and the predetermined calibration setting. In some examples, the calibration setting may be determined in advance by providing a calibration audio output signal to the output device for broadcast, receiving calibration audio input, the calibration audio input including calibration audio content broadcast by the output device in response to receiving the calibration audio output signal, and determining the calibration setting based on at least one difference between the calibration audio output signal and the calibration audio input.Type: GrantFiled: November 22, 2006Date of Patent: June 26, 2012Assignee: Verizon Patent and Licensing Inc.Inventors: Don Relyea, Heath Stallings, Brian Roberts
