    Abstract: A method and apparatus for transcoding digital video data, for example, at the headend of a cable or satellite television network. A generic multi-functional transcoder architecture has a “post-pre-processing engine” that provides a number of processing functions for implementing desired format conversions according to a user selection signal or an automatically generated selection signal. The processing functions can change frame size, frame rate, color space sampling format, interlaced or progressive scan format, resolution, and provide noise/deblocking filtering, for example. The system also allows the control of several transcoders to convert several bit streams with different formats into corresponding bit streams with a common format. Furthermore, the transcoder avoids the need for motion estimation.

    Abstract: A pressure regulator apparatus and method for controlling the pressure in a pressure system is disclosed. The pressure regulator broadly includes a pressure transducer and a regulator control circuit. The pressure transducer measures the pressure of the pressure system, and the regulator control circuit controls the pressure in the pressure system in response to the pressure reading of the pressure transducer. The regulator control circuit compares the measured pressure to a predetermined set-point value for maintaining the pressure within a predetermined optimal pressure range.

    Abstract: The present disclosure generally discloses packet processing offload support capabilities for supporting packet processing offload. The packet processing offload support capabilities may be configured to support general and flexible packet processing offload at an end host by leveraging a processing device (e.g., a smart network interface card (sNIC) or other suitable processing device) added to the end host to support offloading of various packet processing functions from the hypervisor of the end host to the processing device added to the end host. The packet processing offload support capabilities may be configured to support packet processing offload by including, within the end host, a virtualization switch and a packet processing offload agent which may be configured to cooperate to transparently offload at least a portion of the packet processing functions of the end host from the hypervisor of the end host to an sNIC of the end host while keeping the existing management plane and control plane interfaces of the datacenter unmodified.

    Abstract: In one embodiment, a spatial merge mode for a block of video content may be used in merging motion parameters. Spatial merge parameters are considered and do not require utilization of bits or flags or indexing to signal at the encoder or decoder. If the spatial merge mode is determined, the method merges the block of video content with a spatially-located block, where merging shares motion parameters between the spatially-located block and the block of video content.

    Abstract: In various embodiments, a significance map of a matrix of video data coefficients is encoded or decoded using context-based adaptive binary arithmetic coding (CABAC). The significance map scanned line-by-line along a scanning pattern. Each line may be a vertical, horizontal, or diagonal section of the scanning pattern. Context models for each element processed in a particular line are chosen based on values of neighboring elements that are not in the line. Avoiding reliance on neighbors that are in the same line facilitates parallel processing.

    Abstract: Rate control is provided in a two-pass encoder. A first encoding pass is performed to encode an input video sequence. Coding statistics for the first encoding pass are collected. Target coding parameters for a second encoding pass are calculated based on the coding statistics for the first encoding pass. The second encoding pass is performed to encode the input video sequence at a constant bit rate (CBR) using the target coding parameters to form a second pass encoded stream.

    Abstract: A method and apparatus for selecting a coding mode are described. For example, the method receives at least one block of a signal to be encoded. The method determines a frame vertical pixel difference in the at least one block and determines a field vertical pixel difference in the at least one block. The method then compares the frame vertical pixel difference with the field vertical pixel difference to determine a first coding mode for the at least one block.
