In part two of this blog series, I am going to discuss the challenges of multiplexing PC Video and USB 2.0 wirelessly over 802.11n. The PC-on-TV architecture, shown below, illustrates the complete system.  The PC video and audio is presented to the user’s TV or monitor without disturbing any of the existing A/V sources (e.g. cable-TV source, DVD, etc.) connected to the TV.  The PC DVI or HDMI output and USB connection is connected to the PC Extender, which then transmits both video and USB 2.0 wirelessly over 802.11n.  The TV or Monitor Extender receives the transmission and decodes the video and USB 2.0 sending DVI or HDMI to a remote TV or monitor and enabling connection of any USB 2.0 device. 

PC-on-TV Architecture

Let’s examine the PC-on-TV architecture and the three challenges of combining high definition real time PC video with latency sensitive USB 2.0 and transmitting it wirelessly; these challenges are transmitting video, transmitting USB 2.0 and multiplexing video and USB together.

As part one of a three part blog series, I will talk about the increased demand for adding PC-like functionality to the TV and Icron’s innovated solutions to meet this demand. The series highlights the challenges 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 are all achieved with the solution. 

At Icron Technologies, we’ve developed ExtremeLink™ PC-on-TV technology to deliver high quality video and USB 2.0 wirelessly over 802.11n.  Many technology platforms offer video streaming and a subset of other PC functionality to a standard television.  What ExtremeLink™ technology offers is the transmission of high quality video and USB 2.0 to deliver all types of PC interaction including the ability to browse the Internet, access email, instant message, create documents, stream content off a flash drive, play games, and much more.

I will be covering all the challenges and the solution to create a complete “PC-on-TV” solution in this series.   Further, as the market continues to demand more and more wireless connectivity with full PC functionality, the attractiveness of the solution becomes increasingly popular and the technology hurtles have already been addressed.
