FeedBeat is a video aggregating tool that lets you become your own VJ, and broadcast your channel.
The core of the FeedBeat service is the tools used to compile and edit your actual playlist. Once you've found the videos you'd like to add (from sites like YouTube and the rest) they can be saved in your FeedBeat account and used for the creation of your channel. You can also add videos by their URL or search from the FeedBeat editor page. The tools provided to make your channel are pretty inclusive, and offer more than just editing tools, but tracking tools as well.
Sharing your channel is easy enough as well: you can embed your channel into your website or blog page, and viewers can subscribe to your content. This service is strikingly similar to CoolStreaming, right down to the format of the actual channel. Other companies that are providing a way to aggregate videos to create broadcast channels include Magnify, Mogulus, Operator11, Me.tv and Kyte, most of which have additional social features, including an associated community, show schedules and live chat.
