Abstract
High-Definition Multimedia Interface Specification, Version 1.2, supports multiple video formats. Currently the HDMI sources and sinks support multiple formats through reconfiguration of the system. The present invention describes the use of a configurable ‘n’בn’ data pixel mapping matrix for video format conversion. This mapping matrix allows the mapping of any existing video format to any other existing or future video format and allows flexibility of connectivity to any transmitter or receiver. Accordingly a more user friendly implementation that provides greater flexibility for development and use of new formats in video applications is shown.
Claims13
An apparatus for converting video pixel data from one video format to another video format 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;
- 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, thereby enabling the conversion of one video format to another video format.
A method for converting video signals in one video format to another video format using a mapping matrix, the method comprising:
- inputting video signals in a first video format to the mapping matrix;
- and
- applying a plurality of select signals to the mapping matrix, the select signals being operative to enable paths in the mapping matrix that cause video signals at the output of the mapping matrix to be in a second video format.
