Abstract: The present principles relate to a hypothetical reference decoder (HRD) for a Scalable Video Coding extension for a compression algorithm. One such implementation proposes to modify the H.264/AVC HRD for use with the SVC of AVC. That implementation defines HRD constraints for each interoperability point of SVC. One implementation in particular is described, but other implementations are possible and are contemplated by the present principles. The changes for spatial, temporal, and SNR scalability are shown. There are also changes to the related HRD parameters followed that are shown. The several mentioned implementations provide rules for an HRD for SVC. At least one implementation proposes the SVC-HRD rules as modifications to the AVC-HRD rules. A user may use the proposed SVC-HRD rules to build an SVC-HRD and test a bitstream for SVC compliance.

Abstract: A 3D shutter glasses device, coupled via a wireless link to a 3D video display device, maintains a slave clock synchronized with a master clock in the display device. The clocks may comprise Bluetooth clocks. The shutter glasses receive 3D frame display information and time information referenced to the master clock that corresponds to when frames are displayed. The shutter glasses control opening and closing of left and right shutters utilizing slave clock time and the received information. The received display information comprises left, right and/or blank frame pattern information, a frame pattern time interval, a frame refresh rate and a time offset for delaying opening and/or closing of shutters. The time information indicates master clock time when frames are displayed. The shutter glasses and the display maintain synchronization when display and/or time information updates are skipped. The shutter glasses may transmit information to the display device.

Abstract: A video coder associates a first boundary strength value with an edge in response to determining that a first video block or a second video block is associated with an intra-predicted coding unit (CU), where the edge occurs at a boundary between the first video block and the second video block. The video coder may associate a second or a third boundary strength value with the edge when neither the first video block nor the second video block is associated with an intra-predicted CU. The video coder may apply one or more deblocking filters to samples associated with the edge when the edge is associated with the first boundary strength value or the second boundary strength value. The third boundary strength value indicates that the deblocking filters are turned off for the samples associated with the edge.

Abstract: In a machine vision system editing environment for a part program, a continuous stream of image acquisition operations are performed during a run mode. Previously, a continuous stream of image acquisition operations was achieved by utilizing different programming representations and syntax for programming and grouping image acquisition operations together in the part program. A new common syntax and representations are utilized wherein such continuous image acquisition operations are recorded in the same way as regular operations, with the running of the part program being performed in two stages. First, the portion of the part program that is to have the continuous stream of image acquisition is scanned for image acquisition operations, and the most efficient order for acquiring the images is determined. Second, while the image acquisition process is being performed, the portion of the part program is scanned again, with the image analysis operations then being performed.

Abstract: A system is provided for creating binary codewords for transform coefficients used for relating transform units (TUs) divided into coding units (CUs) in a High Efficiency Video Coding (HEVC) system. The system provides binarization of the codewords and removes unnecessary operations to reduce system complexity and increase compression performance. The system generates transform coefficients that relate the TUs and begins by providing a parameter variable (cRiceParam) set to an initial value of zero. Significant transform coefficients are converted into binary codewords based on the current value of the parameter variable, and the parameter variable is then updated with a new current value after each transform coefficient has been converted. Updating can be provided with reference to table values or the values can be provided from combination logic.

Abstract: Multi-mode error concealment, recovery and resilience coding. Adaptation of a number of coding units (CUs) employed in accordance with video coding may be made as a function of error. As a number of errors increases, the respective number of CUs may correspondingly increase (e.g., which may be made in accompaniment with a reduction of CU size). As a number of errors decreases, the respective number of CUs may correspondingly decrease (e.g., which may be made in accompaniment with an increase of CU size). Such errors may be associated with a type of source providing a video signal, a type of error resilience coding employed, communication link and/or channel conditions, a remote error characteristic (e.g., such as associated with a source device and/or destination device), a local error characteristic (e.g., such as associated with operations and/or processing within a given device), and/or any other type of consideration.
