摘要： An ad hoc network may be established between a handheld wireless communication device (HWCD) and one or more network resources utilizing biometric identity information. The biometric identity information may be associated with a user of the HWCD and utilized to select one or more network resources thus enabling secure communication between the HWCD and the one or more network resources. The HWCD may acquire the user's biometric identity information from the user and validate it utilizing stored biometric identity information. The one or more network resources may acquire the HWCD user's biometric identity information from the user and sign the biometric identity information with a private key. The HWCD may receive signed biometric identity information and associated public keys from each of the one or more network resources and validate the signed biometric identity information.

摘要： A system, method, and apparatus for guiding a deinterlacer are presented herein. The deinterlacer is provided a deinterlacing coefficient which the deinterlacer uses to select a deinterlacing scheme which best utilizes system resources. The deinterlacing coefficient is calculated based on the various attributes associated with a macroblock of an interlaced field, such as motion vectors. Because the attributes are calculated and encoded prior to transmission of the macroblock over a communication channel, generation of the deinterlacing coefficient does not require significant additional computation resources.

摘要： The present invention provides an apparatus and method for providing a programmable inverse discrete cosine transform, wherein the transform coefficients are loaded into a memory area of a core transform device and a variety of coding standards can thereby be handled by the same programmable core device. The core device is configured to process a certain sized data block, and the incoming source blocks are converted to conform to this size. After transformation, the proper sized result can be extracted from the transform device output. A switchable speed-up mode provides for 4-point transforms, rather than 8-point transforms. Alternatively, the invention also provides for dedicated transform hardware to be switchably used in conjunction with programmable transform hardware, depending upon the type of coding being used, and the speed of inverse transform desired.

摘要： The present invention provides an apparatus for performing inverse quantization for multiple decoding standards, where the functional operations that comprise the inverse quantizer are modularly implemented and can be selectably performed. Each operation can be represented via a table entry in an associated memory area, with the functional operation being performed via reference to that table entry. Functional operations can be bypassed as needed if inverse quantization does not need to be performed on a set of data. Certain other processing operations can be performed between steps as needed to accommodate different coding standards. Macroblock data can be read from and written back to a common storage area, or a direct path is provided for writing the data directly to a subsequent inverse transform device.

摘要： A system and method for preprocessing a bitstream of compressed video data is presented herein. The bitstream of compressed video data can include, for example, a bitstream in accordance with the MPEG AVC standard. The bitstream is received and modified by a preprocessor to facilitate multi-row decoding. The modifications to the bitstream can include identification of starting points of macroblock rows with row headers. Additionally, multi-row decoding is further facilitated by generation of decode descriptors which indicate the starting row positions in the modified bit stream. Additionally, the modified bit stream can be formatted in accordance with a simpler coding scheme to simplify decompression.
