  • Publication number: 20240155151
    Abstract: Particular embodiments provide a variable, BitDepth, that may be set at a value based on a number of bits used to represent pixels in pictures of a video. The variable may be used in syntax elements in HEVC, such as the HEVC range extension, but other coding standards may be used. By using the variable, different resolutions for the video may be accommodated during the encoding and decoding process. For example, the number of pixels in the pictures may be represented by 8 bits, 10 bits, 12 bits, or another number of bits depending on the resolution. Using the BitDepth variable in the syntax provides flexibility in the motion estimation and motion compensation process. For example, syntax elements used in the weighted prediction process may take into account different numbers of bits used to represent the pictures.

  • Patent number: 11980042
    Abstract: A method for enhancing the performance of pentacene organic field-effect transistor (OFET): an n-type semiconductor thin film was set as a buffer layer between pentacene and polymer electret in the OFET with the structure of gate-electrode/insulating layer/polymer/pentacene/source (drain) electrode. The thickness of n-type organic buffer layer is 1˜100 nm. The induced electrons at the interface lead to the reduction of the height of the hole-barrier formed at the interface, thus effectively reducing the programming/erasing (P/E) gate voltages of pentacene OFET. The widened distribution region of positive space charges caused by ionized donors in n-type organic buffer layer effectively restricts the back-transfer of holes from polymer to pentacene, thus improving the performance of pentacene OFET, such as the P/E speeds, P/E endurance and retention characteristics.

  • Publication number: 20240146935
    Abstract: A system and method of defining a plane for planar coding in JVET in which first and second lines can be defined based upon pixels in left-adjacent and top-adjacent coding units. In some embodiments, the least squares method can be employed to define the relevant lines. One point along each of the lines can then be identified and the y-intercepts of the two lines can be averaged to obtain a third point. The three points can then be used to identify and define a plane for planar coding in JVET.

  • Publication number: 20240146937
    Abstract: A method for inter-coding video is provided in which transmission bandwidth requirements associated with second motion vectors for bi-directional temporal prediction is reduced. In the method motion vector information for only one of the two motion vectors for bi-directional temporal prediction can be transmitted together with information on how to derive or construct the second motion vector. Thus, rather than sending express information regarding two motion vectors, express information related to only one motion vector along with information related to reconstruction/derivation of the second motion vector is transmitted, thus reducing bandwidth requirements and increasing coding efficiency.

  • Publication number: 20240146904
    Abstract: Particular embodiments may remove a condition check in the semantics for checking a high-precision data flag. This simplifies the semantics used in the encoding and decoding process. In this case, even if the high-precision data flag is not set, the value of the weighted prediction syntax element is set by the BitDepth variable. However, even if the BitDepth is not considered high-precision data, such as 8 bits, the range for the weighted prediction syntax element is still the same as the fixed value. For example, the syntax elements luma_offset_l0[i], luma_offset_l1[i], delta_chroma_offset_l0[i][j], and delta_chroma_offset_l1[i][j] use the variable BitDepth as described above whether the flag extended_precision_processing_flag is enabled and not enabled to indicate whether the bit depth is above a threshold.

  • Publication number: 20240137550
    Abstract: A method of decoding JVET video includes receiving a bitstream and calculating a final planar prediction in planar mode to predict pixel values for a current coding block. The final planar prediction may rely on using unequal weights applied to each of a horizontal and vertical predictor, where such predictors may be generated by interpolating neighboring pixels for each predicted pixel within a coding block. The computation may be made more accurate by deriving a value for a bottom right neighboring pixel.

  • Publication number: 20240121425
    Abstract: A method for inter-coding video in which encoder and decoder memory requirements associated with storage of motion information related to collocated coding units is reduced. In the method motion information related to only a single or reduced set of collocated coding unit(s) may be stored at the encoder and decoder. In operation, if the encoder determines that motion information for a current coding unit should replace a currently stored motion information for currently stored motion information for the collocated coding unit, then the encoder can replace the motion information at the encoder and transmit an indicator with the current coding unit to signal to the decoder that currently stored motion information currently should be updated or replaced with the motion information associated with the current coding unit.
