A Japanese company has released its new Grand HD Cinema, a converter device that will convert USB to HDMI. This will be great for those of you with no HDMI interface.
Just a note, when you buy a new laptop, make sure it has an HDMI output. My $600 Dell laptop does, I simply had to make sure it had one before I bought it.
Also read up on my DIY guide that shows you how to connect your PC to your HDTV.
The Grand HD Cinema does indeed take USB video (along with audio) and upconvert the stream to a 720p HDMI signal that can drive six different HDMI devices. As a means to get clips from PMPs to TVs it certainly makes a lot of sense.
