摘要： The present application relates to a method for coding a moving picture in a moving picture coding system using multiple reference picture. According to the method for coding an interlaced moving picture into a frame picture having frame/field macroblock, a reference picture index of the frame macroblock is determined at a macroblock level by determining the reference picture index of frame unit at a picture (or slice) level and respectively allocating a lower index and a higher index to a top reference field and a bottom reference field while sequentially visiting the reference frames according to an order of reference picture index of frame unit, the top and bottom field indexes being giving by an equation: top reference field index = 2 × picture index of reference frame; and bottom reference field index = 2 × picture index of reference frame + 1.

摘要： Embodiments are described which exploit a finding, according to which a higher compression rate or better rate/distortion ratio may be achieved by adopting or predicting second coding parameters used for encoding a second view of the multi-view signal from first coding parameters used in encoding a first view of the multi-view signal. In other words, the inventors found out that the redundancies between views of a multi-view signal are not restricted to the views themselves, such as the video information thereof, but that the coding parameters in parallely encoding these views show similarities which may be exploited in order to further improve the coding rate.

摘要： In an example, system and method for coding encoded video data. A quantized residue differences block associated with a current block of a picture is generated and a reconstructed prediction residue for each quantized residue difference in the block of quantized residue differences is generated. Each reconstructed prediction residue is added to its corresponding original prediction value to produce a current block of a picture. Generating the reconstructed prediction residue includes performing inverse quantization on blocks of quantized residue differences, wherein the inverse quantization reconstructs data to which uniform quantization residue differential pulse code modulation (RDPCM) has been applied and wherein the quantization is of the form: &Dgr;Xq=floor((X+αQ)/Q) where Q is quantization step and α is quantization offset.

摘要： The present invention relates to a method of coding a current field macroblock in a B-frame, comprising: obtaining a reference frame picture list including multiple reference frame pictures; determining a reference frame picture index of the multiple reference frame pictures in the reference frame picture list based on display order information for the multiple reference frame pictures, reference frame picture index numbers being allocated in a display order to reference frame pictures whose display order is higher than a display order of a current frame picture and remaining reference frame picture index numbers being allocated in a reverse order to reference frame pictures whose display order is lower than the display order of the current frame picture, wherein the current frame picture includes the current field macroblock; reordering the reference frame picture index allocated to each reference frame picture in the reference frame picture list; obtaining motion vector information for the current field macroblock; alternately allocating reference field picture indexes that are increased by one to reference field pictures, starting from a reference field picture having a parity equal to a parity of the current field macroblock to a reference field picture having a parity different from the parity of the current field macroblock, while sequentially visiting the reference frame pictures according to the order of the reordered reference frame picture index; and performing motion compensation for the current field macroblock in the B-frame by using the reference field picture indicated by a reference field picture index and the motion vector information for the current field macroblock.

摘要： A video coding device may encode a video signal using intra-block copy prediction. A first picture prediction unit of a first picture may be identified. A second picture may be coded and identified. The second picture may be temporally related to the first picture, and the second picture may include second picture prediction units. A second picture prediction unit that is collocated with the first picture prediction unit may be identified. Prediction information for the first picture prediction unit may be generated. The prediction information may be based on a block vector of the second picture prediction unit that is collocated with the first picture prediction unit.
