Abstract

Official abstract text for this publication.

A wireless display system and method decompresses a compressed video stream, such as obtained from suitable video sources such as a cable modem, DVD player or other suitable source, to produce a decompressed video stream locally. The decompressed video stream, such as frames, is stored in a local frame buffer, such as an on-chip frame buffer, system memory, or any other suitable memory. The system and method then recompresses the stored frames and wirelessly transmits the recompressed frames using a short range wireless transmitter, such as a radio frequency-based short range transmitter, an infrared short range wireless transmitter, or any other suitable short range transmitter that may provide, for example, local area networking. Accordingly, full image frames are decompressed and then recompressed, such as via a software data encoder as executed by a central processing unit, or via a hardware data encoder, such as an MPEGII or MPEG4 encoder, or any other suitable encoder, and then modulated by a short range wireless transceiver and sent to a short range wireless unit having a local display.

First claim

Opening claim text (preview).

What is claimed is: 1. A method for providing image data for a wireless monitor comprising: in a device: processing graphics drawing commands to render graphics data using a first processor to produce rendered graphics image data and storing the rendered graphics image data to a frame buffer; retrieving the rendered graphics image data from the frame buffer over a local bus using a second processor; determining whether a wireless display mode has been selected; in response…
