My kids watch a lot of a TV show called iCarly where they send video out live over the web. If you have always wanted to host your own live web show of video blog, or even broadcast a live sporting event like a kid's football game a new device has surfaced that will let you do just that. The device is called the miniCASTER and it promises to stream live video to the web from any camera.
The miniCASTER can broadcast HD resolution video and can send that video out via landlines, cellular networks, or satellites. The manufacturer says that sending one hour of video using the device on a cellular network will cost in the area of $10. The device encodes the audio/video signal using H.264 in realtime. The H.264 format will work for a bunch of devices like the iPhone, iPad, and works for YouTube, and more.
The big catch here is that the miniCASTER is far from cheap. The entry-level model with analog inputs is about $1300 and the SDI version will sell for $1999. The device has a LAN port for connecting to the web and will soon have WiFi.
