TV Extender Architecture
The TV extender architecture is shown in figure 3.  The transmitted data signal is received by the wireless receiver.  The ExtremeUSB Extender de-multiplexes the USB and video data.  The USB Device Connector allows for multiple connections of a keyboard, mouse, game controller, web camera or any other USB device.  The video data sent to the video processor decodes the signals which are then converted by the DVI transmitter to send DVI or HDMI signals to the remote TV or Monitor.

This article has shown the challenge of combining high-quality video with a true PC experience including USB connectivity for devices with all transfer types (control, interrupt, bulk, and isochronous) to develop a high-performance and stable architecture.   Low latency, high-quality video, optimized bandwidth, and consistent resolution over typical distances within a home were all achieved.  Icron’s ExtremeLink “PC-on-TV” technology is now available as a complete reference design for companies who wish to partner with Icron to customize the feature set and productize the technology to meet their target market.
