摘要： An image processing method and system that performs color space transformation on an image to be compressed and obtaining pixel values, performing intra-row differential pulse code modulation coding on the image pixel values to obtain numerical values, and determining whether each of the numerical values is within a preset range. Variable length coding is performed on the numerical value obtained by using a fixed code table if the numerical value is within the range, variable length and by using a dynamic code table if it is not. Low algorithm complexity and fast processing meets the requirement of real-time video transmission. The pixel components of the image can be processed in parallel and adjacent processing steps can be performed in the same clock frequency, thereby remarkably reducing difficulty and cost in FPGA or chip implementation.

摘要： In accordance with certain described implementation(s), a coordinating device performs bandwidth allocation procedures based on information from previously-unfulfilled bandwidth allocation requests and responsive to current bandwidth allocation requests. The current bandwidth allocation requests stipulate current requested bandwidth amounts for multiple streams, and the current bandwidth allocation requests may be received from multiple entities having the multiple streams. The information from previously-unfulfilled bandwidth allocation requests is taken into account when allocating available bandwidth between/among the multiple streams of the multiple entities for the current requested bandwidth amounts.

摘要： A hardware-independent proxy layer for synchronous processing of commands in a mobile telephone is disclosed. Such synchronous processing may include receiving a function call of an application program interface (API) that is associated with a function to be performed by a mobile telephone, waiting to receive from a driver layer a result notify event indicating that the function has been performed, and, after receiving the result notify event from the driver layer, passing to the client first result data associated with the first result notify event. The API may be translated into an input/output control (IOCTL) code, which may be sent to the driver layer.

摘要： A UMTS extension to the GSM/GPRS RIL is disclosed. The UTMS RIL provides an API set interface for the support of UMTS features such as 3G QoS, secondary PDP contexts call, priority service, voice group call and voice broadcast services, etc. The API set is based on the UMTS AT command interface as defined in 3GPP specification TS 27.007. The architecture of the UMTS RIL is designed as a standard interface with APIs and callback mechanisms that can be used across different platforms and multi-radio hardware such as GSM, GPRS, WCDMA, and HSDPA. The UTMS RIL may enable various applications running on mobile platforms in 2G, 2.5G, and 3G cellular radio stacks to issue commands without knowledge of underlying radio hardware structure.

摘要： A method provides differentiated quality of service (QoS) by providing adaptive updates to media access control (MAC) layer parameters on a distributed basis. The method includes calculating a failure probability for a transmission over the network, determining a target value for determining a contention window according to a mapped function of the failure probability, and altering the contention window according to a scaling function of the target value. The mapped function and the scaling can provide QoS differentiation. A wireless device ensures fairness in a wireless time slotted network and includes a network interface card (NIC), a network driver interface, a network monitor, a statistics engine, and an adaptive parameter engine for determining a target value for determining a contention window according to a mapped function of the one or more probabilities to enable an alteration of the contention window and provide new parameters for the MAC layer.
