Abstract: A system and method for multimedia data transmission including pooling, by a computer, at least first and second multimedia data streams together in a single channel, wherein each stream defines a respective sequence of frames and each frame includes at least a base layer and at least one enhancement layer; dynamically establishing, by the computer, first and second bit rates respectively associated with the first and second streams; and transmitting, by a transmitter, the at least first and second streams on the channel.

Abstract: A mobile computing device with multiple modes, for example, wireless communication and personal computing, has an application processor and a communication processor. In the computing mode, the application processor is the master processor. In the communication mode, the application processor is deenergized to conserve battery power, with the communication processor functioning as the master processor by accessing the device's peripheral bus using the memory interface of the communication processor.

Abstract: A method, apparatus and computer program product for predicting received signal strength in a wireless mobile receiver. The invention bounds the range of allowed values for a next predicted signal. The bounded prediction compensates for erroneous values from multipath fading. The predicted signal strength is used to set the mobile receiver amplifier gain to the desired level.

Abstract: A method and apparatus that allows a telecommunications system using cdma2000 1× to easily migrate to using cdma2000 3×. In other embodiments, the invention provides for better spectrum management, allows concurrent usage of a standard cdma2000 1× reverse link with a cdma2000 1× time-division-duplexing (TDD) reverse link, and provides for hardware supplementation—as opposed to total replacement—when additional services are added to an existing code-division-multiple-access (CDMA) system.

Abstract: A method and apparatus are described for controlling the data rates for communications to and from a base station and a plurality of remote users. The usage of the communications resource whether the forward link resource (from base station to remote users) or reverse link resource (from remote users to base station) is measured. The measured usage value is compared against at least one predetermined threshold value and the data rates of communications or a subset of communications on said communications resource is modified in accordance with said comparisons.

Abstract: A broadcast multimedia data stream is partitioned into two or more parts based on importance, e.g., a first part might represent more significant bits in groups of bits representing pixel colors in a video frame, while a second part might represent the less significant bits in the groups. The more important part of the stream is error correction coded at a lower rate or using a more powerful coding technique (i.e., with more error correction coding) than is the less important part of the stream.

Abstract: A system for synchronizing a second receive chain relative to a first receive chain in a multi-mode communication system. The system includes a first circuit that measures a first frequency associated with the first receive chain. A second circuit adjusts a second frequency associated with the second receive chain based on the first frequency and provides a desired second frequency to the second receive chain in response thereto. In a specific embodiment, the first circuit includes a first counter that receives a signal associated with an output of a first oscillator and provides a measurement of the first frequency in response thereto. The second circuit includes a frequency synthesizer for providing the desired second frequency in response to a frequency control or reference signal. Another circuit generates the control or reference signal based on a difference between the second frequency and the first frequency.

Abstract: The present invention presents a calibrator for a mobile station of a TDMA wireless communications system such that the calibrator calibrates a low-frequency clock to a high frequency clock locked to system timing. When the mobile station is in idle mode (i.e., listening to a paging channel periodically, but otherwise taking no action), the control processor commands the mobile station to enter into sleep mode to minimize power consumption. During sleep mode, the high-frequency reference clock and all clocks derived from it are turned off. Only the calibrated low-frequency clock remains operating to clock the sleep logic.
