Abstract: In a DOCSIS-based communications system, different upstream channel descriptors (UCDs) all identify a single logical upsteam channel identifier (UCID) regardless of the type of cable modem (CM) to which the UCDs are sent. Different CMs having different capabilities (e.g., CMs configured according to the different DOCSIS standards 1.x, 2.0, and 3.0) receive their respective UCDs from an upstream headend. All the UCDs, however, refer to the same logical upstream channel. The different CMs therefore share this single logical upstream channel.

Abstract: Systems and methods are described that utilize audio spatialization to help at least one listener on one end of a communication session differentiate between multiple talkers on another end of the communication session. In accordance with one embodiment, an audio teleconferencing system obtains speech signals originating from different talkers on one end of the communication session, identifies a particular talker in association with each speech signal, and generates mapping information sufficient to assign each speech signal associated with each identified talker to a corresponding audio spatial region. A telephony system communicatively connected to the audio teleconferencing system receives the speech signals and the mapping information, assigns each speech signal to a corresponding audio spatial region based on the mapping information, and plays back each speech signal in its assigned audio spatial region.

Abstract: Systems and methods are described for applying noise suppression to one or more audio signals to generate a noise-suppressed audio signal therefrom. In a single-channel implementation, an input signal is received that comprises a desired audio signal and an additive noise signal. Noise suppression is then applied to the input signal to generate a noise-suppressed signal in a manner that is controlled by at least a parameter that specifies a degree of balance between distortion of the desired audio signal and unnaturalness of a residual noise signal included in the noise-suppressed signal. In an alternative single-channel implementation, a plurality of sub-band signals obtained by applying a frequency conversion process to a time domain representation of an input signal is received. Noise suppression is then applied to each of the sub-band signals by passing each of the sub-band signals through a time direction filter. Multi-channel noise suppression variants are also described.

Abstract: A method and system for content adaptive analog video noise detection are provided. A motion metric (MM) value, an edge detection value, and a content detection value may be determined for pixels in a video image. The MM values of pixels with edge detection values smaller than an edge threshold value and with content detection values smaller than a content threshold value may be collected and accumulated for a portion of the noise level intervals when the MM values fall in this interval. The MM values collected and accumulated may be utilized to determine an average noise level for each of the intervals. A noise level indicator (NLI) for the current video image may be determined based on the noise level of the current image or on the noise levels of the current and at least one previous video images.

In preferred embodiments, the rate control takes into account two or more of these four factors in an integrated manner to change the allocation of bits for encoding different portions of the video stream.

Abstract: A signal processing system which discriminates between voice signals and data signals modulated by a voiceband carrier.

The data exchange is performed by demodulating data signals from the switched circuit network for transmission on the packet based network, and modulating data signal packets from the packet based network for transmission on the switched circuit network. The call discriminator is used to selectively enable the voice exchange and data exchange.
