20120069916 | FREQUENCY OFFSET ESTIMATOR FOR UPSTREAM CABLE SIGNALS - In a DOCSIS transmission network, it is necessary for an upstream receiver to estimate and correct for errors in the carrier frequency of the transmission based upon observations of a preamble sequence. This task is complicated by the fact that microreflections in the upstream channels cause intersymbol interference, which tends to bias the frequency estimation circuit. An economical, ISI-immune algorithm is provided for estimating the carrier frequency of upstream transmissions. The arrangement improves the reliability of the frequency estimates in the presence of ISI, thereby reducing the overhead and increasing the throughput of the upstream channels. | 03-22-2012 |

20130128985 | MULTI-LEVEL SIGNIFICANCE MAP SCANNING - Methods of encoding and decoding for video data are described in which multi-level significance maps are used in the encoding and decoding processes. The significant-coefficient flags that form the significance map are grouped into contiguous groups, and a significant-coefficient-group flag signifies for each group whether that group contains no non-zero significant-coefficient flags. A multi-level scan order may be used in which significant-coefficient flags are scanned group-by-group. The group scan order specifies the order in which the groups are processed, and the scan order specifies the order in which individual significant-coefficient flags within the group are processed. The bitstream may interleave the significant-coefficient-group flags and their corresponding significant-coefficient flags, if any. | 05-23-2013 |
20130188724 | METHODS AND SYSTEMS FOR PIPELINING WITHIN BINARY ARITHMETIC CODING AND DECODING - Methods of encoding and decoding for video data are described for encoding or decoding multi-level significance maps whilst enabling pipelining of the BAC engine. In one example, coefficient groups are redefined to remove the significant-coefficient flags of the first and last position of a block and replace them with significant-coefficient flags of the last position in the previous block and the first position in the next block. A modified scan order is applied to each coefficient group. In another example, the coefficient groups remain block-based, but the scan order is modified to interleave the encoding and decoding sequential coefficient groups. | 07-25-2013 |
20130188726 | METHODS AND DEVICES FOR CONTEXT SET SELECTION - Methods of encoding and decoding for video data are described for encoding or decoding multi-level significance maps. Distinct context sets may be used for encoding the significant-coefficient flags in different regions of the transform unit. In a fixed case, the regions are defined by coefficient group borders. In one example, the upper-left coefficient group is a first region and the other coefficient groups are a second region. In a dynamic case, the regions are defined by coefficient group borders, but the encoder and decoder dynamically determine in which region each coefficient group belongs. Coefficient groups may be assigned to one region or another based on, for example, whether their respective significant-coefficient-group flags were inferred or not. | 07-25-2013 |
20130188735 | METHODS AND DEVICES FOR CONTEXT MODELING TO ENABLE MODULAR PROCESSING - Methods of encoding and decoding for video data are described for encoding or decoding coefficients for a transform unit. In particular, the significant-coefficient flags for a coefficient group are encoded and decoded based upon a context determination, and the context is determined based upon the values of neighboring flags. The neighborhood used to determine the context varies depending on whether the significant-coefficient flag to be encoded or decoded is in the right column or bottom row of the coefficient group or not. If it is in the right column or bottom row one of the alternative context neighborhoods is used to avoid relying on significant-coefficient flags in other coefficient groups except for the flags immediately adjacent the right border and bottom border of the coefficient group, and the flag diagonally to the lower-right. | 07-25-2013 |
20130195200 | METHODS AND DEVICES FOR CONTEXT MODELING TO ENABLE MODULAR PROCESSING - Methods of encoding and decoding for video data are described for encoding or decoding coefficients for a transform unit. In particular, the significant-coefficient flags for a coefficient group are encoded and decoded based upon a context determination, and the context is determined based upon the values of neighboring flags. The neighborhood used to determine the context varies depending on whether the significant-coefficient flag to be encoded or decoded is in the two right columns or two bottom rows of the coefficient group or not. The upper-left corner may also have a different neighborhood. If the flag is in one of the two right columns or two bottom rows one of the alternative context neighborhoods is used to avoid relying on significant-coefficient flags in other coefficient groups. | 08-01-2013 |
20130235925 | UNIFIED TRANSFORM COEFFICIENT ENCODING AND DECODING - Methods and devices for reconstructing coefficient levels from a bitstream of encoded video data for a coefficient group in a transform unit, using adaptive-threshold-based level coding. Threshold is set based upon level information from one or more previously-reconstructed coefficient groups in the transform unit. Threshold may be maximum number of level flags to decode for the coefficient group. Level information may include number of level flags decoded in previous coefficient groups. Previously-reconstructed coefficient groups may include coefficient group to the right and below the current coefficient group. | 09-12-2013 |
20130235940 | METHODS AND DEVICES FOR CONTEXT MODELING TO ENABLE MODULAR PROCESSING - Methods of encoding and decoding for video data are described for encoding or decoding coefficients for a transform unit.

The neighborhood used to determine the context varies depending on whether the significant-coefficient flag to be encoded or decoded is in the right column or bottom row of the coefficient group or not.

20130336410 | METHODS AND DEVICES FOR CODING BINARY SYMBOLS AS N-TUPLES - Methods and devices for reconstructing coefficient levels from a bitstream of encoded video data for a coefficient group in a transform unit. Greater-than-one flags are encoded by grouping them into tuples and by encoding a tuple-based value that is a function of the greater-than-one flags within that tuple. The tuple-based value may permit the decoder to infer the greater-than-one flags in some cases, in which case they are not encoded in the bitstream. | 12-19-2013 |
20140355675 | LOSSY DATA COMPRESSION WITH CONDITIONAL RECONSTRUCTION REFINEMENT - Methods of encoding and decoding media, for example video, using conditional reconstruction refinement are described. The encoding and decoding relies upon predictions that are based on previously encoded and decoded samples. Prediction information identifies the previously reconstructed samples upon which a prediction is to be based and is available to both the encoder and decoder. On the basis that a previously-reconstructed sample is going to be used as source data for a prediction, the encoder refines that reconstructed sample, uses the refined reconstructed sample for the prediction, and encodes refinement data to enable the decoder to also refine the previously-reconstructed sample during decoding. In some cases, a reconstructed sample may be refined more than once. Various flags or bits may be used to signal when refinement is enabled or disabled and may be signaled at various hierarchical points in the coding structure. | 12-04-2014 |
20140362905 | INTRA-CODING MODE-DEPENDENT QUANTIZATION TUNING - Methods of encoding and decoding video are described.

A host monitoring system receives calls from various clients and determines which calls to accept and which to reject by comparing the decoded client serial numbers with a predefined and updated list of numbers corresponding to reported stolen computers. The host also concurrently obtains the caller ID of the calling client to determine the physical location of the client computer. The caller ID and the serial number are subsequently transmitted to a notifying station in order to facilitate the recovery of the stolen device. The security system remains hidden from the user, and actively resists attempts to disable it. | 03-13-2014 |
