October 5, 2013 - At the Screen in the Home conference held by the Santa Clara Valley IEEE Communication Society and Consumer Electronics Society, they had a keynote presentation by Qualcomm Atheros VP of Technology Bill McFarland on streaming technology in the home, This presentation was focused on wireless solutions and powerline solutions for bringing high bandwidth streaming, that is suitable for high frame rate video, inside a typical home. This technology address both the main large screens in the home as well as extra screens on mobile devices and computers/gaming platforms in the home.

The presentation covered the new IEEE 802.11ac wireless capabilities, Wi-Fi Miracast which is a wireless video transfer to a display, HPAV2 Powerline communications in the home, and the compbined specification of the IEEE P1905.1 which covered a unifying and interoperability details for wireless, powerline, ethernet and MOCA in a single hybrid network, One key in understanding the issues in the home is a single solution does not work. Only 11% of homes have CAT5 for connectivity, coax is in most homes but not in every room, mobile devices typically only have wireless support, and parts of a home may be be on other phases of the PLC or near a large capacitive / inductive load that reduce the data bandwidth. As a result, most modern homes need to use a multip-protocol solution to move video content around the house.

The presentation covered the key points of moving video content around which is the MIMO capabilities of these protocols which allow for multi-Mbps to Gbps data transfer rates. These are sufficient for compressed and encoded video that can be unpacked by the destination device at the nominal 24-30fps with 8 bit color video data. This data can originate on a broadcast stream, in a gaming console, on a mobile device or from a in-home network that has a video media server.

The presentation by Bill covered the whole range of options including a Q&A addressing the 60GHz wireless use model, in his presentation.
