摘要： A system and method are provided for calculating a target pixel for scaling an image comprising a plurality of source pixels. A contour is determined in the image using at least one of a first set of predetermined parameters. A filter tap configuration is adaptively selected from a predefined set of filter tap configurations in accordance with the determined contour. The predefined set of configurations includes a plurality of non-linear filter tap configurations. The target pixel is calculated by selectively convolving ones of the plurality of source pixels along a locus of the selected filter tap configuration with a weighting factor, and combining the convolved pixels.

摘要： A digital signal encoding, editing and transmitting method enabling seamless coupling of plural video bitstreams without causing disruption of a decoder buffer. In coupling a second bitstream from an encoding unit 20 to the trailing end of a first bitstream from an encoding unit 10, an encoding unit 12 imposes limitations in encoding for securing a data buffer volume required for startup of the second bitstream in the vicinity of the trailing end of the first bitstream responsive to the control signal from a terminal 14, while an encoding unit 22 imposes limitations in encoding for securing a data buffer volume required for startup of the second bitstream in the vicinity of the leading end of the second bitstream responsive to the control signal from a terminal 24.

摘要： When image reduction is effected at the writing of the image to a frame memory, a first image portion which is to be dropped by the reduction is subjected to weighted-averaging with a second image portion adjacent thereto to modify the second image portion. When an image read from the frame memory is enlarged, a first image portion which is to be added by the enlargement is generated by weighted-averaging two second image portions located before and after the first image portion. When an image is enlarged, it is enlarged by a first enlargement factor in the range of 1 to 2 and enlarged by a second enlargement factor that is an integer, thereby obtaining a result image enlarged by a third enlargement factor that is the product of the first and second enlargement factors.

摘要： A mix-effect bank architecture for a production video switcher has multiple programmable outputs, the outputs being determined by a selected operational mode including split, programmable clean feed and mix minus modes. Four keyers with video and key signal inputs produce four outputs. The outputs are selectively routed to four corresponding inputs of four mixers, which mixers also have two pairs of background/utility video inputs. The four mixers provide four outputs which are determined by the selected operating mode. A pair of background video signals may be provided to all of the mixers to provide programmable clean feed outputs, or the pair of background video signals and a mix minus pair of background video signals may be provided to the mixers to provide mix minus outputs, or a primary set of background video signals may be provided to two mixers and a secondary set of background video signals may be provided to the other two mixers for the split mode.
