The invention relates to capturing, processing, and displaying panoramic content such as video content and image data with a panoramic camera system. In one embodiment, a method for processing panoramic video content may include capturing video content in a data storage medium of a panoramic camera; dividing the captured video content into multiple analysis portions; detecting sound associated with at least one of the analysis portions; identifying content of interest from which at least one sound has been detected; and, automatically panning a field of view for the captured video content in response to the identified content of interest.

The invention provides a method and system for dynamically estimating background noise. The system includes a portable communication device, a vocoder, and a voice activated detector. Based on information received by the portable communication device, the vocoder determines parameters related to incoming information including a voicing mode indicative of the periodicity of incoming information. The voice activated detector then compares the voicing mode to a threshold to determine whether a background noise estimate should be updated. The method includes the steps of: receiving a periodicity indicator and a current comfort noise level for an incoming voice frame; comparing the periodicity indicator with a predetermined threshold if the current comfort noise level is equal to a previous comfort noise level; and maintaining a background noise estimate if the periodicity indicator exceeds the predetermined threshold and revising a background noise estimate if the periodicity indicator does not exceed the predetermined threshold.

A telephone () and a method for providing outbound audio when the telephone is operating in a speakerphone mode. A first data unit () including a first unit type identifier () can be received by the telephone. The first unit type identifier can be an indicator of a type of audio data contained in the first data unit. For instance, the first unit type identifier can indicate whether the audio data is music or non-music audio data. If the first unit type identifier has a first value, for example a value indicating that the audio data is music data, unmuted outbound audio reproduced from the first data unit can be provided and voice activity detection can be disabled. Additionally, inbound audio can be muted.

The invention concerns a method () and system () for improving voice quality of a vocoder (). The method includes the steps of monitoring () a pitch of a voice signal () at a transmitting unit (); when the pitch of the voice signal reaches a predetermined threshold (), shifting () the pitch of the voice signal to at least a portion of a predetermined range (); transmitting () the pitch-shifted voice signal to a receiving unit (); and at the receiving unit, reshifting () the pitch-shifted voice signal to a level that compensates the step of shifting the pitch of the voice signal at the transmitting unit.

A mobile communication device ( ) determines a background noise level at a microphone ( ). If, after determining the noise floor, the input signal exceeds a threshold, the mobile communication device transmits the input signal. The threshold is established such that if it is exceeded, it is likely that voice energy is being received at the microphone, and the threshold, in a first embodiment, is increased as the background noise level increases. In a second embodiment the threshold is determined as the difference between the input signal and the background noise level. As background noise increases, the threshold actually decreases.

A speakerphone arbitration method is used to eliminate the effects of echo in imperfect telephone circuits. The method assumes that speech energy received at the speaker phone is an echo, unless the speech energy has characteristics that indicate it is not echo, such as the duration of the speech energy, and the time at which the speech energy is received relative to the time when the user of the speakerphone finishes speaking, or pauses while speaking. The method also may allow arbitration if the speech energy is more energetic than a typical echo, regardless of the duration or time when it is received.
