Abstract:
A head related transfer function (HRTF), which can be considered as biometric data is used to authenticate a user from whom the HRTF is derived. The HRTF may be used for authentication in combination with other biometric data such as retina scan or fingerprint to render two-factor biometric authentication. The HRTF used for authentication is encrypted for security.
Abstract:
A personalized HRTF is generated from a generic HRTF by having a person don headphones, then select a generic HRTF model from a list. Test signals emulating sounds from a source at a specific virtual speaker location are played on the headphones, and the person indicates where he thinks the emulated sounds are coming from. Any difference between the virtual speaker location and the “heard” location is used to adjust the parameters (amplitude, phase, and frequency response) of the generic HRTF to render a HRTF personalized to the listening person.

Abstract:
A method of scanning television channels at initial setup. The method includes at a first power mode, automatically scanning for channels using a first scanning setup procedure during which the television is unusable by a user. The first power mode is when the television is at a full power mode. The detected channels are automatically provided for use by the television upon completion of the first scanning setup procedure. The method further includes automatically scanning for channels using a second scanning setup procedure at a second power mode following the first power mode. The second power mode is at a lower power mode than the first power mode, and the second scanning setup procedure is more time consuming in comparison to the first scanning setup procedure. Additional channels not detected during the initial setup by the first scanning setup procedure are automatically detected at the second power mode.
Abstract:
A cloud-based HRTF repository system that can be accessed via a public application program interface (API) on the remote repository server to permit individual users of audio-capable client devices to upload and store personalized HRTFs and basic device data in an open format. The cloud server repository includes a computer readable non-volatile memory which further includes a program memory portion comprising an application program interface (API) module configured for receiving HRTF data from a client device, or from a brand manufacturer, and for sending HRTF data to a client device. A brand manufacturer can upload HRTF data to the cloud-based HRTF repository system either directly from their branded companion app in a client device, or optionally via their own cloud server. One technique includes using a Media Service Provider (MSP) app in the client device with a provided server access library (SAL) thereby enabling retrieval of HRTF data for bath a personalized HRTF for any brand client device, or for retrieval of generalized HRTF data by brand manufacturers having a SAL in their brand server via the remote server repository public API.
Abstract:
Thus, in one embodiment an apparatus includes at least one processor, at least one display controlled by the processor, and at least one wireless transceiver communicating with the processor. The processor is configured to transmit a message accessible to at least one recipient that includes data representing at least one non-alphanumeric who icon representing a person, at least one non-alphanumeric what icon representing an event and/or activity, and at least one non-alphanumeric when icon representing a time associated with the event and/or activity. Furthermore, at least one of the following represented by data included in the message is modifiable based on input from at least one recipient: the at least one who icon, the at least one what icon, and the at least one when icon.
Abstract:
A personalized room related transfer function (RRTF) for sound bars and speakers within a specific room is generated without the need for photographs of the listener's head or microphones in a headphone apparatus. A smart device aids the listener in creating his own RRTF by enabling the listener to select a general RRTF model based on the specific sound bar setup (e.g., sound bar; sound bar+subwoofer; sound bar+rear speakers+height; etc.) from a set of general RRTFs downloaded locally or from the cloud. A test signal is played from a specific driver of the sound bar, and the listener identifies a location at which he would like the perceived sound to originate. If the driver location signal and desired location are not the same, the app adjusts parameters and replays the test signal until the driver signal and the desired location are the same.

Abstract:
An audio network box is provided as a master for a networked speaker system. The audio box can be configured with different combinations of modules to provide functionality as may be desired by an end user. The modules may include a power over Ethernet module, a wireless communication module/access point (AP) module, and an analog speaker module.
