Slingbox
The Slingbox is a TV streaming media device made by Sling Media that encodes local video for transmission over the Internet to a remote device (sometimes called placeshifting). It allows users to remotely view and control their cable, satellite, or digital video recorder (DVR) system, at home from a remote Internet-connected PC, smartphone, or tablet as if he or she were at home.
Customers have also connected their Slingboxes to other video sources, including Blu-ray players and security cameras.
