  • Patent number: 9313497
    Abstract: Video compression encoding includes intra and inter prediction to reduce spatial and temporal redundancies in video. Prediction results or residuals represent differences between original video pixel values and predicted pixel values. The prediction residuals may be transformed into coefficients, referred to as transform coefficients, in the frequency domain. The transform coefficients may be quantized and entropy encoded. The transform coefficients can be sub-sampled prior to quantization to reduce their number. For example, sub-sampling may reduce more high frequency components than low frequency components represented in the transform coefficients. Therefore, sub-sampling reduces the number of transform coefficients that need to be quantized, reduces quantization complexity, and correspondingly increases throughput in the encoding.

  • Publication number: 20160073126
    Abstract: Techniques for inter-layer residual prediction are described. In one embodiment, for example, an apparatus may comprise an encoding component to determine whether a predicted motion for an enhancement layer block is consistent with a predicted motion for a collocated lower-layer block, determine whether to apply inter-layer residual prediction to the enhancement layer block based on whether the predicted motion for the enhancement layer block is consistent with the predicted motion for the collocated lower-layer block, and in response to a determination that inter-layer residual prediction is to be applied to the enhancement layer block, generate a predicted residual for the enhancement layer block based on a residual for the collocated lower-layer block and generate a second-order residual for the enhancement layer block by comparing a calculated residual to the predicted residual. Other embodiments are described and claimed.

  • Publication number: 20160029040
    Abstract: A three-dimensional (3D) video codec encodes multiple views of a 3D video, each including texture and depth components. The encoders of the codec encode video blocks of their respective views based on a set of prediction parameters, such as quad-tree split flags, prediction modes, partition sizes, motion fields, inter directions, reference indices, luma intra modes, and chroma intra modes. The prediction parameters may be inherited across different views and different ones of the texture and depth components.

  • Publication number: 20150304682
    Abstract: Methods and systems to apply motion estimation (ME) based on reconstructed reference pictures in a B frame or in a P frame at a video decoder. For a P frame, projective ME may be performed to obtain a motion vector (MV) for a current input block. In a B frame, both projective ME and mirror ME may be performed to obtain an MV for the current input block. The ME process can be performed on sub-partitions of the input block, which may reduce the prediction error without increasing the amount of MV information in the bitstream. Decoder-side ME can be applied for the prediction of existing inter frame coding modes, and traditional ME or the decoder-side ME can be adaptively selected to predict a coding mode based on a rate distribution optimization (RDO) criterion.

  • Publication number: 20150261367
    Abstract: The present invention discloses an in-cell touch panel, a manufacturing method thereof and a display device. A plurality of nanowire arrays are added between an array substrate and an opposite substrate, nanowires in each nanowire array extend in a direction perpendicular to the array substrate and the opposite substrate; the newly-added nanowire arrays and s pacers provided between the array substrate an d the opposite substrate form piezoelectric sensitive elements. Thus, when cell thickness between the array substrate and the opposite substrate is slightly changed due to pressure on the touch panel by any object, a nanowire array may be slightly deformed by squeeze of a spacer, the deformed nanowire array may release charges to change an electrical signal applied to an electrode wire connected thereto, and a touch point can be positioned by detecting a change in the electrical signal, thus achieving high touch sensitivity.
