A digital-imaging based code symbol reading system which automatically detects hand-induced vibration when the user attempts to read one or more 1D and / or 2D code symbols on an object, and controls system operation in order to reduce motion blur in digital images captured by the hand-supportable system, whether operated in a snap-shot or video image capture mode. An accelerometer sensor is used to automatically detect hand / system acceleration in a vector space during system operation. In a first embodiment, digital image capture is initiated when the user manually depresses a trigger switch, and decode processed only when the measured acceleration of the hand-supportable housing is below predetermined acceleration threshold levels. In another embodiment, digital image capture is initiated when an object is automatically detected in the field of view of the system, and decode processed only when the measured acceleration of the hand-supportable housing is below predetermined acceleration threshold levels.

Coding techniques for a (e.g., OFDM) communication system capable of transmitting data on a number of "transmission channels" at different information bit rates based on the channels' achieved SNR. A base code is used in combination with common or variable puncturing to achieve different coding rates required by the transmission channels. The data (i.e., information bits) for a data transmission is encoded with the base code, and the coded bits for each channel (or group of channels with the similar transmission capabilities) are punctured to achieve the required coding rate. The coded bits may be interleaved (e.g., to combat fading and remove correlation between coded bits in each modulation symbol) prior to puncturing. The unpunctured coded bits are grouped into non-binary symbols and mapped to modulation symbols (e.g., using Gray mapping). The modulation symbol may be "pre-conditioned" and prior to transmission.

A system and method for creating a graphical program, wherein the graphical program is operable to invoke execution of textual code. The user selects a code node for inclusion in the graphical program, wherein the code node is displayed on the screen. The user then selects or enters textual code that is comprised in or displayed in the code node. The textual code may be code from a text-based language, such as Perl, Mathematica, or Java, etc., or may be a script from a scripting language. The user may manually enter the textual code into the code node, or import the textual code from a file. The textual code comprised in the code node is user viewable and editable. During execution of the graphical program, the code node is operable to invoke execution of the textual code comprised in the code node. The textual code is preferably executed by an instance of a server program. During execution of the graphical program, the graphical programming system provides the textual code to the server program, as well as any input data received by the code node. The server program then executes the textual code, using any input data received by the code node, and produces an output which is provided back to the graphical program. The present invention thus enables a user of a graphical programming system to more easily incorporate, view, edit and debug textual based code from within the graphical programming system.

An encoder uses output symbol subsymbols to effect or control a tradeoff of computational effort and overhead efficiency to, for example, greatly reduce computational effort for the cost of a small amount of overhead efficiency. An encoder reads an ordered plurality of input symbols, comprising an input file or input stream, and produces output subsymbol. The ordered plurality of input symbols are each selected from an input alphabet, and the generated output subsymbols comprise selections among an output subsymbol alphabet. An output subsymbol is generated using a function evaluator applied to subsymbols of the input symbols. The encoder may be called one or more times, each time producing an output subsymbol. Output subsymbols can then be assembled into output symbols and transmitted to their destination. The functions used to generate the output subsymbols from the input subsymbols can be XOR's of some of the input subsymbols and these functions are obtained from a linear code defined over an extension field of GF(2) by transforming each entry in a generator or parity-check matrix of this code into an appropriate binary matrix using a regular representation of the extension field over GF(2). In a decoder, output subsymbols received by the recipient are obtained from output symbols transmitted from one sender that generated those output symbols based on an encoding of an input sequence (file, stream, etc.).

Systems, apparatuses and methods whereby a base coded video signal is provided to a decoder having a set of post-processing stages. The base coded video signal can be decoded to produce a base decoded video signal. Post-processing of the base decoded video signal can be used to produce an enhanced quality video output signal. Application of a post-processing stage can be implemented according to the capabilities of the decoder and / or the instantaneous operating parameters of the decoder and / or characteristics of a display. A control signal, communicated over a dedicated channel separate from the base coded video signal, can be used initiate and / or aid implementation of a post-processing stage. The control signal can also provide information to assist / manage the decoding of the base coded video signal. The use of additional post-processing stages increases the complexity of an overall decoding process while improving the quality of a resulting reproduced video sequence.

A communication system provides for data collection and route discovery for a network of distributed nodes. A base code having a data collection function occasionally sends agent packets to selected nodes of the network (620), and these nodes in turn route the agent packets to other nodes. A route suitability level is maintained for each node that reflects the suitability of that node for routing packets to the base node (5 10). At least some data packets contain reporting criteria for particular nodes (620). When a condition exists at a node that meets the reporting criteria, a selected packet is updated with reporting data, and routed toward the based node via a neighbor node based on the route suitability level of the neighbor node (550,552,555).

A system and method for encoding and decoding an input video signal representative of an original moving or still image. The system includes a subsystem for low-bit rate encoding, transmission, and decoding of the moving or still image, and a server / client based buffering subsystem for receiving and decoding the encoded transmission. The client / server based buffering subsystem uses pre-cached and pre-determined content to counteract channel data overflow and create seamless viewing of the moving or still image. The encoding-decoding subsystem processes the input video signal into a format suitable for transmission and subsequent decoding be deconstructing and quantizing the signal into a waveform representing its component elementary parts according to a pre-determined luminance / chrominance gradient field or matrix of defined amplitude. The waveform is generated according to an optimally structured base code within the luminance / chrominance gradient matrix field as defined by minimum sampling rates. The waveform accurately describes the original moving or still image, within an acceptable visible variation as compared to an acceptable bit-rate for the capacity of a given transmission channel. The base code is compressed by a lossless data compression method that is dependent on transmission channel capacity limitations and / or resultant code size. The compressed command code can be transmitted to either a storage facility or to a client. If transmitted to a client, the code is decompressed into the original base code and then decoded by client-side software or hardware to reconstruct the original image within the pre-determined luminance / chrominance gradient field matrix and a pre-defined or sent coding table. The reconstructed original moving or still image can then be displayed on a video display device. Systematic use of the system and method offers a seamless viewing experience on the client side even if the size of the transmitted code exceeds the transmission channel capacity.

A method compresses a set of correlated signals by first converting each signal to a sequence of integers, which are further organized as a set of bit-planes. An inverse accumulator is applied to each bit-plane to produce a bit-plane of shifted bits, which are permuted according to a predetermined permutation to produce bit-planes of permuted bits. Each bit-plane of permuted bits is partitioned into a set of blocks of bits. Syndrome bits are generated for each block of bits according to a rate-adaptive base code. Subsequently, the syndrome bits are decompressed in a decoder to recover the original correlated signals.

Provided is a method for performing hierarchical B picture-based coding on a video sequence using the structure of adaptively divided group of pictures (GOP). The method includes the steps of, for each predefined 2N frame-sized group of pictures (GOP) of the video sequence, (a) encoding the 2N frame-sized GOP of the video sequence based on each of the different GOP sizes from the maximum size, 2N, to the minimum size, 2M (M is an integer between 1 and N) and obtaining different values between frames reconstructed after the encoding is performed and frames after the hierarchical B-picture prediction is performed, based on each of the different GOP sizes; (b) selecting at least one sub-GOP based on the difference values obtained by encoding the 2N frame-sized GOP of the video sequence based on each of the different GOP sizes; and (c) generating a bitstream by encoding the 2N-frame-sized GOP based on the at least one selected sub-GOP. Thereby, the hierarchical B picture-based video coding is performed by adaptively dividing the GOP size based on performance and thereby obtains high coding efficiency.

Methods and units are shown for supporting a switching from a first coding scheme to a Modified Discrete Cosine Transform (MDCT) based coding scheme calculating a forward or inverse MDCT with a window (h(n)) of a first type for a respective coding frame, which satisfies constraints of perfect reconstruction. To avoid discontinuities during the switching, it is proposed that for a transient frame immediately after a switching, a sequence of windows (h0(n),h1(n),h2(n)) is provided for the forward and the inverse MDCTs. The windows of the window sequence are shorter than windows of the first type. The window sequence splits the spectrum of a respective first coding frame into nearly uncorrelated spectral components when used as basis for forward MDCTs, and the second half of the last window (h2(n)) of the sequence of windows is identical to the second half of a window of the first type.

The present invention demonstrates how network-coding can be applied to a deterministic broadcast approach, resulting in significant reductions in the number of transmissions in the network. We propose two algorithms, that rely only on local two-hop topology information and make extensive use of opportunistic listening to reduce the number of transmissions: 1) a simple XOR-based coding algorithm and 2) a Reed-Solomon based coding algorithm that determines the optimal coding gain achievable for a coding algorithm that relies only on local information.
