Abstract
Digital Visual Interface (DVI), or High Definition Multi-media Interface (HDMI), data is received from a source and sent to a transmitter chip that includes a transition minimized differential signaling (TMDS) receiver that outputs a 3-data and 1-clock physical signaling stream representing the DVI or HDMI data. This stream is rendered into I and Q data by an ASIC or FPGA and sent to a wireless transmitter for modulation, upconverting, and transmission to, e.g., a nearby display device without ever rendering the data into baseband video on the transmitter chip. The display device has a receiver chip that is essentially the inverse of the transmitter chip.

1-7. (canceled)
A method for wireless transmission of video data, comprising:
- receiving the video data at a physical signaling stream receiver;
- rendering the data into a physical signaling stream;
- rendering the physical signaling stream into data suitable for modulation by a radio transmitter, the rendering acts being undertaken without rendering the data into baseband video at any time;
- wirelessly transmitting the data;
- receiving the data;
- rendering demodulated data from the received data;
- rendering physical signaling stream data from the demodulated data, the rendering acts being undertaken without rendering the data into baseband video at any time;
- and
- outputting the data to a display device using a physical signaling stream transmitter.
A digital video transmitter, comprising:
- at least one transmitter processor configured to receive a physical signaling stream representing digital video data and based thereon, without rendering baseband information representing the digital video data, outputting a quadrature signal suitable for processing by a wireless transmitter.
14-18. (canceled)
A digital video receiver, comprising:
- at least one receiver processor configured to receive a demodulated quadrature signal and based thereon, without rendering baseband information representing the digital video data, outputting a physical signaling stream representing digital video data.
