Teradek has made a name for itself with its Cube line of wireless video transmitters. The Cube encodes video from HD-SDI sources and HDMI sources, then transmits it over Wi-Fi for viewing on a computer, iPad or other device. I've been very impressed with their progress over the years, and this NAB they announced several new products and features. Their updated Cube is the same size as previous versions, but features a side OLED screen, which shows the Cube's status and allows for quick adjustment of settings.
