Desktop Video Broadcasting has evolved into a very easy tool to use. Where it was once a technology that required high-end equipment, video cameras, audio input devices and perhaps a small team of assistants, it is now a technology that is possible from many desktop and laptop computers.
Basic Video Broadcasting requires a Webcam, an internal microphone, a high-speed Internet connection and an online service hosting your broadcast.
Advanced broadcasting requires a higher-end Webcam (I suggest one that does at least 640X480 or VGA resolution, but the higher the better). You should also consider a stand-alone microphone (Blue makes some great ones...I have a Yeti and it's amazing!) A headset also works very well. Those by Logitec and Plantronics are very good. Stand-alone mics isolate your audio input so that there is less of a chance of incorporating excess noise into your broadcast.
High-speed Internet connectivity is a must. Keep in mind though that all "high-speed" is not the same. For a quality Video Broadcast I suggest a minimum of 1.5 megabites upload and 3-5 megabites download speed. Again, the faster the better. Wireless access will sometimes cause problems because wireless signals are prone to interference and dropped packets which result in loss of audio, stuttering video or stalling in your broadcast.
Finally, you will need a good broadcasting host service. All of the programs below are either free or have both a free and paid service. Services that I have tried and like are:
UStream.tv - Their site states: Ustream is the leading live interactive broadcast platform that enables anyone with an Internet connection and a camera to engage their audience in a meaningful, immediate way. Unlike previous webcasting technology, Ustream uses a one-to-many model, which means that the user can broadcast to an audience of unlimited size. Ustream's platform has been used to broadcast everything from high school sporting events to Hollywood movie premieres, and people are finding new and innovative uses for it every day.
Livestream.com - According to their Website, Livestream is the most powerful online video broadcast solution available. In just minutes you can create broadcasts as polished as any multi-million dollar traditional television network — with full capability to easily broadcast Live, 24/7 Linear, and On-Demand content — absolutely FREE.
Audio Broadcasting is also much easier now than it ever has been. Voice is a compelling medium to express our thoughts and in the Humanities, well, that's what we do, right?
Broadcasting from a handheld device while on the go or from your residence can be done using a number of tools. One that I plan to make use of is:
iPadio - According to their site, ipadio allows you to broadcast from any phone to the Internet live. Phone blog, collect audio data, record and update the world, or simply let your mates know what you're doing - ipadio is integrated with Social Media & Blogging platforms. Here is a link to my iPadio Broadcast Page
Bambuser - Broadcast what's happening around you and chat with your friends while doing so. Available for a variety of hand held devices...works great
SocialCam - Supposedly the easiest way to get your handheld videos online and shared with your friends.
Twitter - Twitter is a "micro-blogging" service where whatever you say must be written using 140 characters or less. It is a very popular platform for quick updates to whatever you are doing. Once you create a Twitter account, there are a variety of applications that use the Twitter API to enable Audio Tweets, Video Tweets and even one that allows "Live Tweeting". Anyone following you on Twitter will have access to your posts directly from their handheld device, email, or by logging in to the Twitter Website. Twitter, along with a number of associated applications will also optionally "Geo-tag" your location.
TwitCam - According to their Website, Twitcam posts your video description and link to Twitter for all your followers to see. While broadcasting, chat with your viewers via Twitter right from your broadcast page. Once you’re done going live, we archive your video and display it on the same page.
TwitVid - TwitVid allows you to upload and share a video through you Twitter account. Upload from your computer, handheld device or Webcam.
Audioboo - According to their Website, we are a mobile & web platform that effortlessly allows you to record and upload audio for your friends, family or the rest of the world to hear.
TwitCasting - Another "Live" Twitter service that enables video and audio broadcasting from your desktop or handheld device. The application is available in the App Store on iTunes. This app appears to be popular in Japan.
TwitSmart - According to their site, you can add Voice and Video to your Tweets. Using TwitSmart, it's easy to keep up with your Twitter activity. See your friends timeline, send and receive direct messages, reply to tweets, and more. And, you can attach your voice and an image to each tweet that you send!
Veetle - Watch and broadcast live video from your phone, iPhone and Android.
Using any of these tools will enable anyone with something to say, and even those who don't, to "Broadcast to the Masses"..Most of the sites above will also host archives of your broadcasts for "On Demand" viewing or listening for those who miss your "live" show. Have fun!
