20110002389 | METHODS AND SYSTEMS TO ESTIMATE MOTION BASED ON RECONSTRUCTED REFERENCE FRAMES AT A VIDEO DECODER - 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.

20120294370 | SYSTEM AND METHOD FOR LOW COMPLEXITY MOTION VECTOR DERIVATION - A system and method for performing candidate-based decoder-side motion vector determination (DMVD).

Alternatively, a small range integer search may be performed around the chosen rounded candidate MV, and the best integer pixel in the search area may be identified and used to define the final MV. Alternatively, an intermediate MV may be chosen, where this MV is intermediate between the chosen rounded candidate MV and the MV corresponding to the best integer pixel in the search area. | 11-22-2012 |

In other implementations, reconstructed luma values of neighboring chroma pixel positions may be analyzed to adaptively predict a chroma value for a chroma pixel position. | 05-30-2013 |
20130188692 | SYSTEMS, METHODS, AND COMPUTER PROGRAM PRODUCTS FOR TRANSFORM COEFFICIENT SUB-SAMPLING - 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. | 07-25-2013 |

The choice of certain layer(s) may be dependent on the desired attributes of the resulting video. A certain level of video quality, frame rate, resolution, and/or bit depth may be desired, for example. The coefficients in the chosen layers may then be assembled to create a version of the residue to be used in video decoding. | 05-22-2014 |
20140146890 | SYSTEM AND METHOD FOR ENHANCED DMVD PROCESSING - To let decoder side motion vector derivation (DMVD) coded blocks be decoded in parallel, decoder side motion estimation (ME) dependency on spatially neighboring reconstructed pixels can be removed. Mirror ME and projective ME are only performed on two reference pictures, and the spatially neighboring reconstructed pixels will not be considered in the measurement metric of the decoder side ME. Also, at a video decoder, motion estimation for a target block in a current picture can be performed by calculating a motion vector for a spatially neighboring DMVD block, using the calculated motion vector to predict motion vectors of neighboring blocks of the DMVD block, and decoding the DMVD block and the target block in parallel. In addition, determining a best motion vector for a target block in a current picture can be performed by searching only candidate motion vectors in a search window, wherein candidate motion vectors are derived from a small range motion search around motion vectors of neighboring blocks. | 05-29-2014 |
