摘要： A method for deinterlacing a picture is disclosed. The method generally includes the steps of (A) determining a protection condition by performing a static check on the picture in a region around a location interlaced with a first field of the picture, (B) calculating an interpolated sample at the location by temporal averaging the first field with a second field in response to the protection condition indicating significant vertical activity and (C) calculating the interpolated sample at the location by spatial filtering the first field in response to the protection condition indicating insignificant vertical activity.

摘要： A method and apparatus for simultaneously processing data in a wireless communication system comprises a wireless transmit/receive unit (WTRU) having a plurality of communication links. The WTRU determines desired characteristics for each communication link. Data traffic is mapped to at least one communication link based on the link characteristics, and a desired redundancy level. The processed data is then transmitted on the at least one communication link, along with the redundancy information.

摘要： A method of signaling additional chroma QP offset values that are specific to quantization groups is provided, in which each quantization group explicitly specifies its own set of chroma QP offset values. Alternatively, a table of possible sets of chroma QP offset values is specified in the header area of the picture, and each quantization group uses an index to select an entry from the table for determining its own set of chroma QP offset values. The quantization group specific chroma QP offset values are then used to determine the chroma QP values for blocks within the quantization group in addition to chroma QP offset values already specified for higher levels of the video coding hierarchy.
