Abstract
A system uses GPU accessible, high-speed memory to store compressed or raw video printer data. The system transmits this video data over one or more frames of an HDMI interface and a circuit reconstructs the video data for a page from one or more HDMI frames for communication to a printer.
Claims27
A printer interface, comprising:
- a high-definition media interface (HDMI) in which multiple frames represent a single page on a printer;
- said high-definition media interface (HDMI) further comprising:
- an HDMI transmitter;
- and
- an HDMI receiver;
- wherein said HDMI transmitter transmits a standard frame size multiple times a second to represent motion to mimic a standard HDMI video transmission such that the HDMI receiver operates as though it is receiving standard video frames;
- wherein a page which has more pixels than a typical video display is broken up into multiple frames;
- and
- wherein said frames are transmitted by said HDMI transmitter and said pages are reconstructed from an output of said HDMI receiver.
6 more elements
A method, comprising:
- transmitting printer data as video data over one or more frames of an HDMI interface;
- and
- reconstructing said video data for a physical page and/or page media which denotes a final pixel being drawn from said one or more HDMI frames for communication as print data to a printer.
A method, comprising:
- providing a high-definition media interface (HDMI) in which multiple frames represent a single page on a printer, wherein said high-definition media interface (HDMI) comprises an HDMI transmitter and an HDMI receiver;
- said HDMI transmitter transmitting a standard frame size multiple times a second to represent motion to mimic a standard HDMI video transmission such that the HDMI receiver operates as though it is receiving standard video frames;
- breaking up a page which has more pixels than a typical video display into multiple frames;
- transmitting said frames by said HDMI transmitter;
- and
- reconstructing said pages from an output of said HDMI receiver.
