Abstract: In a video application, a method and system provide different sizes of data-fetch where the data transfer rate between a decoder and an external memory (e.g., DDR memory) is extremely high, as for example in HDTV systems. The invention in one form divides a reference frame into different tiles where each tile is hierarchically divided into smaller tiles to a level where the minimum tile size is the same as the fixed burst size of the DDR memory. The method also provides for arranging the biggest tiles into different banks and pages so that even if the block to be fetched falls across tile boundaries, the latency penalty in the tile transition will be minimized. The invention provides advantages also for progressive and interlaced data fetch.

Abstract: A technique for continuously recognizing a character entry into a computer. In one example embodiment, this is achieved by drawing a character in a continuous stroke order using a stylus [210] on touch screen [220]. As associated data of the drawn continuous stroke order is then inputted into a continuous character recognizer [930] via the touch screen [220]. One or more hypothesis candidate characters including the continuous stroke order are then produced by the continuous character recognizer [930] upon a partial recognition. The produced one or more hypothesis candidate characters are then displayed substantially over the drawn continuous stroke order on a display device [230].

Abstract: An improved decoding process as applied to MPEG AAC decoders of the type that use codebooks, reduces redundant traversing steps while finding the location of a specific binary stream codeword in the codebook. To this end, the codebooks are divided into a plurality of node-tables, each table corresponding to a node. From the number of bits “k” in a given node-table, the decimal value of the first “k” bits in a binary stream to be decoded is ascertained and compared with the decimal value of the maximum code word in the given node-table. The comparison is used for the identification of the location of the codeword in the node-tables to assist in decoding without unnecessary traversing of all the nodes in the codebook.

Abstract: A method (and algorithm) for detection of 802.11a and 802.11b frames in an 802.11 transmission, calculates DCC (delayed copy correlation) and LCC (local copy correlation) magnitudes and compares their normalized values with threshold values. When a signal is detected, (i.e., AGC locks) the algorithm checks for a valid 802.11a frame, and it exploits the DCC properties of the received symbols. Because of the repetitions of short preambles in received symbols, the DCC is high when the short preamble symbols are present. Further, 802.11b detection may be based on Barker correlation properties simultaneously. A counter array is maintained for each position in a Barker window, and is incremented if the normalized LCC of the incoming sequence with the Barker code exceeds a threshold. An 802.11b packet is declared if the maximum value of the counter array exceeds a predetermined number in a specified number of Barker windows.

Abstract: A non-iterative and computationally efficient bit allocation technique for perceptual audio coders employing uniform quantization schemes. This is achieved by computing a target MNR for all critical bands in a frame using a target bit rate and associated SMRs. Associated SNRs are then computed for the critical bands using the computed target MNR and the associated SMRs. Bits are then allocated to the critical bands based on the computed associated SNRs.

Abstract: A method for achieving bit rate controlled encoding, e.g., constant bit rate, uses a bit rate control model based on bits allocated per macroblock and based on error in estimating bits consumed in an encoding process in a macroblock. The method computes bits consumed per macroblock as a function of the formed bit rate control model, and allocates bits for the macroblock. To this end, a quadratic (second order) equation is used for the model, which equation might default into a first order equation requiring fewer computations, in the event that no second order solutions exist. In one form, the bit rate control model computes the bit rate to satisfy video buffer verifier (VBV) compliance in accordance with MPEG requirements. The bit rate control model makes allowances for the type of macroblock, i.e., inter, intra or bidirectional, and provides for any frame-skips.

Abstract: A method of enhancing security in network management for SNMPv2c packet traffic over internet between a (sending) manager location and an (receiving) agent location uses a pluggable security application function. The manager location has a manager side security application (MSA) and may include one or more managers. The agent location has an agent side security application (ASA) and may include one or more agents. Upon a SNMP request from a manager to the MSA, the request is encrypted, appended with authentication digest and sent to a registered agent in ASA. The MSA receives a secured response packet back from the ASA, which after authentication decrypts and forwards it to the intended manager. Thus, an existing protocol implementation is maintained, while reducing additional network overhead. The method obviates the use of IPSec tunnels and migration to SNMPv3.

Abstract: A technique and method provide virtual N-way video conferencing to participants having IP stations/videophones, which have limited processing capacity, by auto-selecting a limited subset of the participants for video display and restricting the rest of the participants to voice-only mode which requires reduced processing capability. The method uses a virtual n-way conferencing module (VNCM) to provide the video conferencing, and an auto caller select module (ACSM) for causing selective video display. Some of the participants might have VoIP terminals instead of IP videophones. The invention includes a technique, e.g., by using a video transmission control module (VTCM) for reducing the bandwidth requirement of IP videophones by signaling the participants in voice-only mode not to transmit the video information in bandwidth-constrained situations.

At another step a configuration code is received selectively into the application sector of the first memory and into the second memory. At a further step the interrupt/s that is/are being received via the communication link are disabled. At a further step the common sector of the first memory is updated from the second memory.

Abstract: A method of designing a IEEE 802.11n modem starting from a IEEE 802.11a/g modem using a programmable FFT (Fast Fourier Transform) based on a half length FFT core, modifies data in a reception chain implemented in a IEEE 802.11n standard application. The method uses a N/2 FFT which is validated, along with a wrapper; and, extends and applies the validated N/2 FFT, (e.g., 64 FFT) to a N FFT (e.g., 128 FFT) by splitting the N FFT into two smaller first and second FFTs. The first FFT is applied to selected data samples (e.g., even samples) from the N FFT and the second FFT is applied to remaining data samples (e.g., odd samples) from the N FFT to complete data-handling, wherein the extending step is based on Danielson-Lanczos formula using a reduced number of Cordics. The method is also suitable for IFFT computations in IEEE 802.11n MIMO OFDM modem designs.
