    • According to one embodiment, video data from a video transmitter (110) is received (420) at a network buffer (130). Information that pertains to a network buffer drain rate (14) of the network buffer (1q3) is monitored (430). The network buffer drain rate (140) is a rate that the video data is removed from the network buffer (130). The network buffer drain rate (140) is estimated (440) based on the monitored information. A transmission rate (120) that the video transmitter (110) transmits future video data is adjusted (450) to not exceed an allowed transmission rate (ATR) that is calculated based on the estimation of the network buffer drain rate (140).

    • The present invention is a two-step, contour-sensitive deinterlacing technique. The first step of the technique determines for each missing pixel of an interlaced frame of image pixels whether the absolute difference between the pixels above and below the missing pixel is greater than a preselected threshold value. If it is decided that the missing pixel lies at a low-vertical frequency location, its value is estimated via vertical interpolation. Otherwise, the second step is carried out. The goal of the second step is to determine whether or not there is a well-defined contour passing through the missing pixel, and to determine its direction if there is one. In the presence of a well-defined contour, the missing pixel is obtained by averaging the intensity values along the direction of the contour in the field lines immediately above and below the missing field line. Otherwise the process effectively falls back to vertical interpolation. The presence of a well-defined contour is detected by comparing the summed absolute differences (SAD) of blocks of pixels along a predetermined set of candidate directions, including the vertical direction, and selecting the direction associated with the least SAD. The fall-back to vertical interpolation in the absence of a well-defined contour is implicit due to the weighting of the SAD corresponding to the vertical direction.
    • 本发明是两步轮廓敏感的去隔行技术。 该技术的第一步确定图像像素的隔行帧的每个丢失像素,无论丢失像素之上和之下的像素之间的绝对差是否大于预先选择的阈值。 如果确定丢失的像素位于低垂直频率位置,则通过垂直插值估计其值。 否则,执行第二步。 第二步的目标是确定是否存在通过缺失像素的明确定义的轮廓,并确定其方向是否存在。 在存在明确定义的轮廓的情况下,通过在紧邻失踪场线上方和下方的场线中对沿着轮廓方向的强度值进行平均来获得缺失像素。 否则,该过程有效地回到垂直内插。 通过比较沿着包括垂直方向的预定候选方向集合的像素块的总和绝对差(SAD)以及选择与最小SAD相关联的方向来检测明确定义的轮廓的存在。 由于对应于垂直方向的SAD的加权,在没有明确定义的轮廓的情况下,回退到垂直内插是隐含的。

    • A hybrid deinterlace mechanism employs motion detection as a precursor to select the value for each missing pixel of a deinterlaced frame, which is generated by using four consecutive fields to produce a motion detection map that is subsequently coupled to a deinterlacer, together with a selected two of the four consecutive fields. These two selected fields and the motion map are sufficient for the deinterlacer to completely characterize the resulting deinterlaced frame. The deinterlacer switches between vertical interpolation and merging based upon motion. Motion is detected by applying a logic OR operation to respective even and odd field binary motion detection signals. In the absence of motion, the pixel values of an odd field and its immediately succeeding even field are merged. On the other hand, if motion is detected, vertical interpolation is carried out for the even field, by a linear combination of immediately adjacent pixels, respectively above and below the pixel of interest.
