Abstract: Implementations include methods and systems for a converting reference images or video to 3D images or video. A two-step conversion is described which accomplishes warping and hole filling on a pixel-by-pixel basis. In one implementation, of a plurality of pixel values of a reference image at a plurality of first collinear pixels locations are successively mapped to a respective plurality of second pixel locations of a destination image. Between two of the mappings, a location of a hole between two of the second pixel locations may be identified and filled.

Abstract: As part of a video encoding or decoding operation on video data, a video coder performs a coding operation for a current video unit of the video data. As part of performing the coding operation for the current video unit, the video coder determines the availabilities of one or more video units that neighbor the current video unit. In order to determine the availability of a video unit that neighbors the current video unit, the video coder identifies, based on availabilities of video units that neighbor a parent video unit of the current video unit, an entry in a lookup table. The identified entry indicates the availability of the video unit that neighbors the current video unit. The video coder then performs a coding operation on the current video unit based on whether the video unit that neighbors the current video unit is available.

Abstract: A set of even interpolated sub-pixels is formed based on a pixel window and a tap coefficient register having a tap coefficient set, the pixel window is shifted and, applying the tap coefficient register a set of odd interpolated pixels is formed. The set of even interpolated sub-pixels and the set of odd interpolated sub-pixels are accumulated, repeatedly, until a termination condition is let. In the accumulating, the tap coefficient register is updated with another tap coefficient set, the pixel window is shifted, and the even interpolated pixels are incremented, the pixel window is then shifted again and the odd interpolated pixels are incremented.

Abstract: A method for performing texture decoding in a multi-threaded processor includes substantially simultaneously decoding, in multiple hardware threads, at least two macro-blocks of a VP8 frame. Each hardware thread decodes one macro-block at a time. The method may also include assigning a macro-block from the at least two macro-blocks of the VP8 frame to a hardware thread of the multi-threaded processor.

Abstract: A method includes executing, at a processor, a dedicated arithmetic encoding instruction. The dedicated arithmetic encoding instruction accepts a plurality of inputs including a first range, a first offset, and a first state and produces one or more outputs based on the plurality of inputs. The method also includes storing a second state, realigning the first range to produce a second range, and realigning the first offset to produce a second offset based on the one or more outputs of the dedicated arithmetic encoding instruction.

Abstract: Techniques for reducing bus traffic during texture decoding of a video bitstream are provided. In one configuration, a wireless communication device (e.g., cellular phone, etc.) comprises a processor configured to execute instructions operative to decode and separate in a bitstream macroblock (MB) information and residual packet data. The residual packet data is used to generate codec-independent non-zero MB-packets having a universal order that is codec independent. The codec-independent non-zero MB-packets and MB information are then used for reconstructing pixels of a respective frame of the video bitstream.
