Just as it has sought to offset slower CD sales with its digital music store, Walmart--the nation's largest DVD retailer--is looking to insure against lower DVD sales by purchasing the online video company Vudu.
But Vudu isn't just another Internet video company with a loopy name offering a pure over-the-top video service. Like Sezmi, its delivery method is an interesting hybrid. While Sezmi leverages free over-the-air TV, leased spectrum, and broadband (with ample local storage as a force multiplier), Vudu uses a hybrid peer-to-peer model. Content is both delivered to a Vudu device through a standard client/server model, as well as peer-to-peer between different Vudu devices. Additionally, content is pre-positioned at the edge of the network to increase the number of peers.
