Abstract: In a video processing system, a method and system for dynamic selection of transform size in a video decoder based on signal content are provided. For high profile mode video decoding operations, inverse transform sizes may be selected from a 4×4 or an 8×8 inverse transform size based on a transform size syntax element generated by the encoding operation and transmitted as part of the encoded video information bit stream. A set of rules is defined for selecting the transform size based on a macroblock type and a size of the macroblock type of a received macroblock in a video decoder. Dynamic selection of transform size may be performed on intra-coded macroblocks, inter-coded macroblocks, and/or direct mode inter-coded macroblocks.

Abstract: Reading data from a magnetic storage media with an analog front end (AFE) coupled to an all digital read channel compensation architecture. A read head passes over magnetic storage media to produce an analog signal. The analog signal is amplified such that the range of the amplified analog signal substantial matches a range of the analog to digital converter (ADC) used to sample the analog signal. A baseline adjust is performed on the amplified analog signal to center the amplified analog signal to a midscale of the ADC. The amplified analog signal may be sampled where the sampling is data frequency locked by a data lock clock (DLC) tracking module. A digital signal may then be produced from the amplified analog signal where this signal is read channel compensated in the digital domain to produce a digital signal which is then processed with a sequence detector.

Abstract: According to the present invention, simultaneous call-handling and data transfer is achieved between a terminal and a multi-line gateway in a cordless telephony environment. Multiple logical channels are established and used as signaling resources for calls on the multiple lines, and also for data transfers between the gateway and terminal. As a result, terminals can handle multiple calls on different lines and at the same time access data stored at the gateway. According to a first aspect of the present invention, two or more logical channels are established over an asynchronous channel between a terminal and a gateway. These logical channels are assigned to calls that are set-up between the terminal and gateway. When used as a signaling resource, the logical channels allow the terminal to distinguish between signaling information for multiple simultaneous calls. The calls are associated with another speech or data channel that will bear the voice signal, referred to herein as a bearer channel.

The system and method automatically generates an output audio signal by applying beamforming to a plurality of audio signals produced by an array of microphones when it is determined that such beamforming is working effectively and generates the output audio signal based on an audio signal produced by a designated microphone within the array of microphones when it is determined that the beamforming is not working effectively. Depending upon the implementation, the determination of whether the beamforming is working effectively may be based upon a measure of distortion associated with the beamformer response, an estimated level of reverberation, and/or the rate at which a computed look direction used to control the beamformer changes.

For example, the mobile communication system may operate in a power-save mode (e.g., a mode in which the mobile communication system does not communicate messages). The mobile communication system may exit the power-save mode. After exiting from the power-save mode, the mobile communication system may determine to establish communication with a second system (e.g., a message server) over a second communication path instead of a first communication path. Communication with the second system may be established over the second communication path, and message-related information may be communicated between the mobile communication system and the second system. Such message-related information may, for example, comprise message information, information regarding message availability, or information regarding the communication of message information.

Abstract: A system and method for performing audio source localization that uses minimum variance distortionless response (MVDR) beams or other super-directive beams that are more suitable for reducing noise, interference and/or acoustic coupling than the delay-and-sum beams conventionally used in performing audio source localization based on a Steered Response Power (SRP) approach.

This metric involves identifying which beam provides the smallest measure of distortion with respect to a reference power or reference response.
