    摘要： Systems and methods are provided for receiving and encoding 3D video. The receiving method comprises: accepting a bitstream with a current video frame encoded with two interlaced fields, in a MPEG2, MPEG4, or H.264 standard; decoding a current frame top field; decoding a current frame bottom field; and, presenting the decoded top and bottom fields as a 3D frame image. In some aspects, the method presents the decoded top and bottom fields as a stereo-view image. In other aspects, the method accepts 2D selection commands in response to a trigger such as receiving a supplemental enhancement information (SEI) message, an analysis of display capabilities, manual selection, or receiver system configuration. Then, only one of the current frame interlaced fields is decoded, and a 2D frame image is presented.

    摘要： Reduced complexity inverse discrete cosine transform (IDCT) masks and a method for reducing the number of IDCT calculations in video decoding are provided. The method comprises: accepting an n×m matrix of DCT coefficients; performing (n−y) horizontal IDCT operations, where y is greater than 0; performing y scaling operations; and, generating an n×m block of pixel information. Some aspects of the method further comprise: performing (m−z) vertical IDCT operations, where z is in the range between 0 and m/2. In some aspects, performing (n−y) horizontal ICDT operations includes performing IDCT operations for the first (n−y) horizontal rows. Then, performing y scaling operations includes: selecting the DC component from the first position of each horizontal row; scaling the selected DC component; and, copying the scaled DC component into the remaining positions of each of horizontal row.
