Abstract: Methods, systems, and products are disclosed for enabling memory module slots in a computing system after a repair action, the computing system having a plurality of memory module slots and having at least one memory module installed in one of the memory module slots, that includes: determining, during a boot process for the computing system, whether any of the memory module slots are disabled; and if any of the memory module slots are disabled: retrieving, for each memory module installed in one of the memory module slots, a memory module identifier for that memory module, retrieving, from non-volatile memory of the computing system, previously stored memory module identifiers, determining whether the retrieved memory module identifiers match the previously stored memory module identifiers, and enabling the disabled memory module slots if the retrieved memory module identifiers do not match the previously stored memory module identifiers.

Abstract: Disclosed is a system and a method for compressing digitized color video data by generating codes into a pattern of tables for regions in frames of the video data exhibiting certain patterns. An image frame in a video data stream has a plurality of pixels assigned digitized color and luminance data. The image frame is divided into a plurality of non-overlapping elementary units, with each elementary unit comprising a plurality of pixels. For elementary units exhibiting change from the prior frame in time, elementary units having pixels with differing digitized color and luminance data are selected for pattern matching. Each pixel of an elementary unit selected for pattern matching is mapped to a pattern value. A pattern value is the same for all pixels sharing the same color and luminance data in an elementary unit. The pattern values are then grouped based on relative position in the elementary unit into offsets into associated sets of pattern match tables and error condition tables.

Abstract: A data communication system contains a dual-port/dual-access-mode storage subsystem, and a communication controller connecting between that subsystem and external data communication channels. The storage subsystem includes one or more dual-port/dual-access mode storage devices consisting of a pair of random access and sequential access memory arrays, with a parallel block transfer connection between the arrays. The sequential access array can store a large block of up to N bytes (N for example equal to 256), and the random access array can store multiple such blocks. The subsystem also has RAM and SAM access ports respectively controllable in random access and sequential access modes and respectively connecting to the random access and sequential access arrays.

Abstract: A system and method of compressing original video data expressed in a plurality of digitally coded frames which enable decompression and playback of resulting compressed video data at one of a plurality of frame rates while maintaining temporal fidelity of the frames displayed. Compression includes selecting a plurality of rate streams for the compressed video data, including a highest rate stream including all of the frames of the original video data and a lowest rate stream including a subset of regularly spaced frames of the original video data. Then the initial frame in the original video data is spatially compressed and the resulting compressed data placed in the compressed video data. The initial frame is also saved as a base frame for all rate streams for subsequent temporal compression of the original video data.

Abstract: Decompression of video segments from a sequence of differential frames is done by selected scaling of frame resolution and color depth. A frame header indicates the computational complexity of decompression of a frame, allowing selection of scales for output resolution and color depth. Decompression proceeds by retrieving a frame from the compressed video stream in elementary units. An elementary unit is characterized by types, including an unchanged type, a homogeneous type, a pattern type and a predetermined pattern type. For a retrieved elementary unit of the unchanged type, an output pointer to a display buffer is moved by an elementary unit scaled by the output resolution scale. For a retrieved elementary unit of the homogeneous type, a color retrieved from the compressed video stream is applied to an area in the display buffer corresponding to an elementary unit scaled by the output resolution scale.
