I have nothing against instructors using the name of a military unit to sell either their own hand-to-hand combat system or one that is used effectively by that unit. Not at all. For the most part, I see this as a marketing thing and each instructor/author has to make decisions on that front.
If you want to connect a USB device to an HDMI device then you must use a converter box. This is a set of electronics that change the protocols and signals. The only adaptor which works is the DVI-HDMI ones.
HDMI Cables. HDMI is becoming the standard way to connect your HD TV to other devices, such as a DVD or Blu-ray player or a Sky Box. The cable carries a high-quality digital signal, transferring audio and video. Easy to use, as both sides of the cable are identical and plug straight into the TV/device.
