"Back in December of 2003 we heard about a company called DigitalDeck that supposedly had a product in the works that not only could stream digital media files from a networked PC, but could also pause live TV and stream the show to another room and let you pick-up where they left off. It almost sounded too good to be true, plus there weren't any screen shots available so we dismissed it as possible vaporware. However, since then they have introduced and developed their DigitalDeck Entertainment Network product line which consists of the Advanced Media Manager software application, Send & Play Adapter, Play Adapter, and Management Unit (DVR unit for distributed content)."As far as I can tell the DigitalDeck Entertainment Network is a modular system that connects the different adapter units together to form your entertainment network. The Send & Play Adapter that connects up to four A/V source devices (cable/satellite TV set-top, DVD player, TiVo, etc.) appears to be the best of them all. Read
