The invention provides for new polymer compounds and methods for the preparation of modular narrow band gap conjugated compounds and polymers that incorporate exocyclic cross-conjugated donors or substituents, as well as novel monomer components of such polymers and the resulting products which comprise materials and useful electronic devices with novel functionality.

Narrow band gap conjugated polymers employing cross-conjugated donors useful in electronic devices

A method for interpolating a pixel value of a pixel located at an OSD object during frame rate conversion includes determining current forward motion vectors between a first previous video frame and a current video frame, and at least one other set of forward motion vectors between two temporally consecutive previous video frames. The method also includes determining that a block adjoining a target block includes pixels depicting at least a portion of an OSD object. The method also includes determining that a position of the adjoining block relative to the target block coincides with a direction of a current forward motion vector associated with the target block, setting a magnitude of the current forward motion vector to zero (0), and calculating a pixel value of a pixel in the target block in the interpolated video frame based on the current forward motion vector associated with the target block.

A portion of the number of bits initially allocated for encoding some of the frames of a group of pictures (GOP) is accumulated in a bit bank and is subsequently used to encode other frames that may require a larger number of bits to encode than those initially allocated for these frames. Furthermore, when a scene change P frame is detected in a first GOP, a second GOP is formed. The second GOP includes the scene change P frame as well as the remaining unencoded frames of the original GOP. The P frame of the first GOP is changed to an I frame in the second GOP. Furthermore, the frame to be displayed after the I frame of the second GOP is also changed to a duplicate of the I frame of the second GOP.

Bit rate control for motion compensated video compression system

To detect color motion artifacts in a video frame, a motion-compensated color-distance value is compared against a threshold value. If the motion-compensated color-distance value is greater than or equal to the threshold value, color-motion artifacts are detected. The motion-compensated color-distance value is a sum of absolute values of the differences between corresponding pixel values of the video frame and a reference frame. To detect color motion artifacts in a video frame, in another embodiment, luminance and chrominance components of the intra-frame activity levels are compared against luminance and chrominance components of the inter-frame activity levels. If any of the components of the inter-frame activity levels is greater than the corresponding components of the intra-frame activity levels, color-motion artifacts are detected. To reduce color-motion artifacts, either a smaller quantization scale or intra-frame encoding is used to encode the data.
