Low-cost wireless projector interface device using TI TMS320DM270

Personal computers today have 802.11 (b/a/g) -based wireless connectivity. By connecting laptops to a projector wirelessly, multiple persons could connect to the projector and present the content on their laptops. This typically requires another personal computer at the projector end that is wirelessly connected to the laptop and which receives, decodes, and renders a compressed version of what was rendered on the display of the laptop. On the laptop, the screen buffer is captured and the captured frames are compressed. The encoded stream is streamed over the WLAN to a streaming client. The article presents a low cost interface device for the projector system based on the TI TMS320DM270 image/video processor.
