Abstract

Systems and methods that facilitate wireless display via employing a frame buffer encoder and a wireless transmission as part of a graphics card of a computing device. The encoder can encode a scheme programmable in software to detect type of format the receiving monitor is capable of displaying. The wireless transmission can occur in a variety of formats; such as Ultra Wide Band (UWB), Internet Protocol (IP) data packets, and the like.

Claims

1. A system that facilitates wireless display comprising:

a graphics card with an encoder that reads data from a buffer and encodes the data to form a data stream forwarded to a transmitter; and

the transmitter that wirelessly transmits the data stream to a decoder operatively connected to a monitor.

2. The system of claim 1 further comprising a Graphical Processing Unit that generates pixel data that is stored in the frame buffer.

3. The system of claim 2 further comprising a Central Processing Unit that forwards an uncompressed stream of video data to the Graphical Processing Unit.

4. The system of claim 1 the transmitter transmits data in at least one of an Ultra Wide Band and an Internet Protocol.

5. The system of claim 1, the encoder encodes a scheme programmable in software to detect the type of format the monitor displays.

6. The system of claim 1, the decoder is part of the monitor.

7. The system of claim 1, the frame buffer is uploaded at regular intervals.

8. The system of claim 1, the encoder employs a Motion Picture Expert Group Standard.

9. The system of claim 1, the transmitter supplies a compressed wireless data stream to the monitor.

10. A method of wireless display comprising:

reading data from a frame buffer via an encoder at a computing side of a wireless display system; and

encoding data stored in the frame buffer to form a data stream for wireless transmittal to a monitor side of the wireless display system.

11. The method of claim 10 further comprising converting high level semantics to graphical data via a Graphical Processing Unit at the computing side of the wireless display system.

12. The method of claim 10 further comprising forwarding an uncompressed stream of video data to the Graphical Processing Unit via a Central Processing Unit.

13. The method of claim 12 further comprising controlling the Graphical Processing Unit by system level software running on the Central Processing Unit during a terminal services session.

14. The method of claim 10 further comprising transmitting data to the monitor side by employing at least one of an Ultra Wide Band and an Internet Protocol.

15. The method of claim 14 further comprising detecting a display format of the monitor side.

16. The method of claim 14, further comprising encoding a scheme programmable in software to detect the display format of the monitor side.

17. The method of claim 14, further comprising receiving the data stream via a dongle of the monitor side.

18. The method of claim 17 further comprising decoding the data stream via an encoder associated with the dongle.

19. The method of claim 17 further comprising uploading the frame buffer at regular intervals.

20. A system for wireless display comprising:

means for generating pixel data to be stored in a buffer means;

means for encoding the pixel data in to a data stream; and

means for transmitting the data stream to a monitor side.
