Je viens de tomber sur http://www.tvblob.com/
ils sortent un appareil qui permet d'appeler quelqu'un en visioconférence via sa TV.
ça remplace la webcam sur PC. C'est en qualité TV ...
ça peut enregistrer aussi sur un disque dur interne.

Bon, il faut juste avoir une TV , un ligne ADSL haut-débit et ... une caméra !
Sinon c'est intéressant :

Stream corporate video.

• Transfer: Stream video both for one-off events and for routine, ongoing feeds, using low-cost, consumer-quality broadband, without the need for expensive dedicated lines or satellite connections.
• Multicast: Broadcast in real time to one or more users on a multicast-enabled network: from a live camera, a single video file, or a playlist
• Video On Demand: Make video archive files available on demand to other TVBLOB users on your network, with one simple on/off setting.
• Playlist Manager: Save video files for easy access and later replay.

Make corporate TV programs and channels.

• Live Recordings: Easily record video from live cameras or other local or remote sources.
• Private Channels: Create your own multicast channel with scheduled or looping video. Keep remote locations linked together 24-7 in video and/or make video training resources available to everyone.
• Archive Manager: Store files locally in a video archive using standard file management features. For more complex video libraries, leverage the TVBLOB Content Management System.
• Web Browser: Remotely manage and distribute video capture and delivery across multiple locations.
