Patent ID: 8269897

Claim:
An apparatus for converting video pixel data from a first component video format to a second component video format, the apparatus comprising: a mapping matrix having a plurality of inputs and a plurality of outputs, the number of said plurality of inputs being equal to the number of said plurality of outputs; the mapping matrix having a plurality of multiplexers, each of the plurality of multiplexers having a number of outputs equal to the number of outputs to the mapping matrix and a number of inputs equal to the number of inputs to the mapping matrix, each of the plurality of multiplexers being implemented using a plurality of smaller multiplexers connected hierarchically, each multiplexer decoding a selection signal provided to the each of the plurality of multiplexers to provide the selection signals for the plurality of smaller multiplexers; a plurality of selection signals coupled to the mapping matrix, each of said plurality of selection signals enabled to activate a path between an input of said mapping matrix to an output of said mapping matrix; and a control unit enabled to generate said plurality of selection signals to allow the mapping of each of said plurality of inputs to each of said plurality of outputs without simultaneously mapping any two of said plurality of inputs to any single output of the said plurality of outputs, wherein the plurality of inputs receive video pixel data in the first component video format and the plurality of outputs output video pixel data in the component second video format, the apparatus enabling the conversion of the first component video format to the second component video format, wherein the first component video format is different from the second component video format, said first and second component video formats being high definition multimedia formats connected through a high definition multimedia interface (HDMI), the control unit being preconfigured to perform any of a plurality of different component video format conversions; the apparatus consisting of at least a portion of an integrated circuit.
