However you are using streaming video as a teaching tool, using a smartphone or an iPad and free and low-cost services today make it accessible and effective.
Ten years ago, streaming video was low-quality, hard to produce, and expensive to deliver. Today it’s easy to produce with inexpensive equipment and can be delivered to your online viewers by free or low-cost Web video distribution services. Or you can deliver broadcast-quality, high-definition live productions if you have a substantial budget. And even a “substantial” live production budget is a lot less today than it was in 2002.
Live streaming is real time, and needs one connection from the streaming server to the Internet for each viewer. Progressive delivery shoots data packets out over the Internet that are reassembled by the client — or viewing — computer back into a coherent video. Hardly anyone does true “live streaming” any more. If you have a webcam and two computers, you can set up a chat between your two computers using Skype, Yahoo Messenger or Google Hangout and see for yourself that there’s a noticeable lag between your “live” self and your “chat” self. The lag is caused by your image and voice getting broken down into data packets, sent through the various wires and fiber optic lines and routers and other equipment between the send and receiving ends, and getting assembled back into a viewable video. In real life, though, this lag is no problem because hardly anybody looks at the live event and watches the streaming video rendition of it at the same time.

Google Hangout isn’t only for Presidents. You can easily set up your own Google+ Brand Page and host your own Google Hangouts. In fact, here are five hangout ideas meant for retailers, that are also useful for everyone from kindergarten teachers to college instructors to choir leaders.
Skype in the Classroom is designed for distance learning, where the teacher is in one room and some (or all) of the students are in another room—and through Skype, the other room can be on the other side of the world.
Skype video isn’t limited to school use. It’s also great for training — it will even let you share a
