On Global Multimedia Network Based on a Hybrid Network Media

The Main Elements of the Multimedia Network Internet Short Introduction

Reflector and Multicast Let’s try Retranslator (Reflector) It’s unicast protocol Let’s try UDP multicast on the LAN Internet

Internet Satellite Receiving Without Back Channel Regular sat dish, regular PC, DVB adaptor ($50)

Satellite Reflector Satellite Reflector Internet A Solution for Global Media Network

Reflecting of Passive Satellite Receiving into the Internet Internet The example shows only receiving to simplify the diagram Regular PC

ISDN User Participating Receives via the satellite and sends via ISDN

Equipment for the Central Office Translators Ser- ver Speaker ViaSat ISDN Server- Gate Moderator ISDN Ser- ver Internet LAN It’s the minimal set of equipment for one way translations and multipoint conferences Moderator invites participants, controls discuss process, give to participants permissions to speak, controls content of video window Participants can choose the language of translation The speaker computer can be used to show presentations

Equipment for Reflector

Equipment for Active Participants Internet Receives and sends via the Internet Receives via the satellite and sends via the Internet Receives and sends via the satellite

Equipment for Passive Viewers Internet

The End of Part 1

Examples of the Communicator Case

Conference Participant Window in Control Mode Selection of translation Language Selection of bitrate Parameters of receiving data Window for the conference Activation of control menu Information about current data source

Moderator Control Window Participants’ buttons Windows sizes and positions control scheme control Active speakers’ windows Imaging Control

Conference Participant Screen (Regular Mode) The screen look very depends number of participants and kind of show selected by moderator

Engineering menu for Transmitter

Engineering Menu of Receiving Control

Engineering Menu for Network
