Various methods are provided for generating motion vectors in the context of 3D computer-generated images. An example method includes generating, based on a current frame to be rendered, a block-level motion vector with depth (MVD) texture comprising a set of block-level motion vectors each having an associated depth value, outputting the block-level MVD texture for image processing on a first channel, and outputting at least a portion of the current frame on a second channel.

Methods and systems for dual channel transfer of game

Various methods are provided for the generation of motion vectors in the context of 3D computer-generated images. In one example, a method includes generating, for each pixel of one or more objects to be rendered in a current frame, a 1-phase motion vector (MV1) and a 0-phase motion vector (MV0), each MV1 and MV0 having an associated depth value, to thereby form an MV1 texture and an MV0 texture, each MV0 determined based on a camera MV0 and an object MV0, and outputting MV1 texture and the MV0 texture for image processing.

Methods and systems for 0-phase motion vectors in 3D graphics

Various methods are provided for generating motion vectors in the context of 3D computer-generated images. An example method includes generating, for each pixel of one or more objects to be rendered in a current frame, a 1-phase motion vector (MV) and a 0-phase motion vector (MV), each MVand MVhaving an associated depth value, to thereby form an MVtexture and an MVtexture; converting the MVtexture to a set of MVblocks and converting the MVtexture to a set of MVblocks; and outputting the set of MVblocks and the set of MVblocks for image processing.

A method and system for detecting and processing a series of video frames includes receiving the series of video frames, determining whether the video frames are associated with a recognized non-video source, and depending on the determination, processing the video frames using a variety of techniques. A system may detect whether each video frame is a repeat frame or a new original frame, keep the new original frames, discard the repeat frames, and then adjust one or more timestamps associated with the new original frames so as to conform to an intermediate frame rate. The frame indexes and timestamps associated with the new original frames are stored in a FIFO or buffer. The system can interpolate video frames using the stored timestamps, and output a series of video frames. The output video stream is delivered at any frame rate and can include original video frames and interpolated video frames.

A system including a memory configured to store a plurality of initial frames of a video signal and a plurality of motion vectors; and a multi-frame interpolator coupled to the memory and including a first output port and a second output port, the frame interpolator configured to generate a first output frame and a second output frame from the initial frames and the motion vectors, to output the first output frame through the first output port and output the second output frame through the second output port.

Multi-channel video frame interpolation

We describe a device and an associated method that includes an EHT signal processing module to generate a compensated gain signal responsive to a first EHT signal. A field fly-back processing module generates a first correcting signal responsive to a first VFB signal. A horizontal scanning correction module generates a predistortion signal responsive to the compensated gain signal. A first digital to analog conversion module converts the predistortion signal into a corresponding analog predistortion signal. A field scanning correction module generates a correcting wave responsive to the compensated gain signal and the first correcting signal. A pulse width modulated module generates a modulated correcting wave by pulse width modulating the correcting wave. A power amplification module generates an amplified modulated correcting wave by amplifying the modulated correcting wave. And a cathode ray tube displays an image responsive to the analog predistortion signal and the amplified modulated correcting wave.
