Where Apple goes, Sony is soon to follow. Or vice-versa. So Apple has its wireless gadget for getting iTunes video to your TV. And so will Sony, maybe.
A chance encounter on the train from Makuhari station to Tokyo, I overheard talk about a possible video-streaming system for Sony Vaio PCs that uses ultrawideband to send uncompressed high-def video to TVs. On the PC end, it requires adding a wireless chip. On the TV end, there will probably be a wireless adapter that simply plugs into the HDMI audio/video port.
Watch for it in the next couple years.—Sean Captain
