Abstract:
Described herein are techniques related to motion and quality adaptive rolling intra (I) macro-block (MB) that is used to encode a particular image frame. In particular, the rolling I MB configuration may be based upon global motion direction, quantization parameter (QP) value, complexity based roll, and/or QP saturation based roll.
Abstract:
Methods, systems and computer program products that may improve the efficiency of the video encoding process. Mode decision processing and bit stream packing may be performed in parallel for various frames in a sequence. This reduces the amount of idle time for both the mode decision processing logic and the bit stream packing logic, improving the overall efficiency of the video encoder.

Abstract:
Systems, devices and methods are described including applying nonlinear scaling to a current image frame and a reference image frame to generate at least a corresponding current image layer and a corresponding reference image layer. Hierarchical motion estimation may then be performed using the nonlinearly scaled image layers. Further, source block size may be adaptively determined in a downsampled image layer and hierarchical motion estimation may be performed using the adaptively sized source blocks.

Abstract:
Systems, devices and methods are described for performing hierarchical motion estimation by downsampling a current frame to generate a downsampled current frame, specifying a downsampled block in the downsampled current frame, where the downsampled block corresponds to a block of the current frame, and specifying a source block associated with the downsampled block, where the source block is larger than the downsampled block. Motion estimation may then be performed in a downsampled reference frame using the source block.
Abstract:
Systems, devices and methods are described including determining an inter-view coding mode for at least a portion of an image frame, specifying a corresponding value of an inter-view coding mode indicator, and providing the mode indicator in a bitstream that includes an encoded motion vector associated with the image frame portion. A first value of the mode indicator corresponds to a first inter-view coding mode where the encoded motion vector includes components in multiple dimensions. A second value of the mode indicator corresponds to a second inter-view coding mode where the encoded motion vector components include components in only one dimension.

Abstract:
In one embodiment, an apparatus and method for an angular-directed spatial deinterlacer are disclosed. In one embodiment, the method comprises calculating a cost measure for each of multiple angle candidates for a target pixel block to be deinterlaced in a spatial-only domain, determining a horizontal angle measure for the target pixel block, establishing a global minimum angle from the multiple angle candidates by determining the lowest cost measure from the multiple angle candidates, establishing a local minimum angle from the multiple angle candidates by sifting through the angle candidates in a hierarchical manner, and filtering the global minimum angle and the local minimum angle to create a value for interpolating the target pixel block for deinterlacing. Other embodiments are also described.
