摘要： A method (which can be computer implemented) for addressing errors during migration of software applications includes the step of obtaining access to a data repository, which includes a listing of migration decisions and a listing of dependencies associated with the migration decisions. The method further includes the steps of obtaining an indication of a migration error, tracing the migration error to at least a first one of the migration decisions in the data repository, and employing the listing of dependencies to identify at least a second one of the migration decisions, depending on the at least first one of the migration decisions identified in the tracing step, which is impacted by the migration error. Techniques for populating the data repository are also provided.

摘要： A system for the introduction of controlled correlation among multiple redundant representations of predictively encoded signals while avoiding predictive mismatch at a receiver when any given sub-set of the multiple representations is received. The system embodies a signal encoder and decoder. The decoder can comprise at least two signal adders for respectively receiving coefficient values and adding at least one predictive value transform to the coefficient value in order to generate and transmit a second set of coefficient values. The second set of coefficient values is subsequently received by a decoder means, wherein the decoder means transforms the received coefficient values and transmits the resultant coefficient values to a signal adder. Upon reception of the transformed coefficient values, the signal adder generates a third set of coefficient values; the third set of coefficients being used to reconstruct an approximate version of an encoded signal.

摘要： An encode control strategy is provided for variable bit rate encoding of a sequence of video frames in a single pass. The control strategy includes determining whether a video frame has a complexity level statistically outside a defined range from a complexity level of at least one preceding frame of the sequence of video frames, and if so, determining a new average bit rate target for the video frame. The new average bit rate for the video frame is determined employing at least one of spatial complexity and temporal complexity of the video frame. The new average bit rate target for the video frame is used to set frame level bit rate control parameter(s), and the video frame is encoded using the set frame level bit rate control parameter(s).

摘要： A method and apparatus, particularly suited to SIMD instruction sets, to filter streaming video information encoded under a predictive encoding algorithm specified under video encoding standards, such as MPEG 4 or H.264/AVC. The filtering operation de-blocks or removes unwanted borders in the perceived video. During the filtering process, a series of filtering mask is generated based on temporal and spatial statistics of predictive encoded video information, which is then recursively applied to the video in order to gate filtered or unfiltered video to an output channel according to coefficients of the masks. The filtering mask effectively yields a decision or rule-based map that transforms the video on a pixel-by-pixel basis thereby avoiding complex and processor-intensive decision tree logic customarily required to process individual pixels of successive macroblocks that may have different filtering requirements.
