Transportation media are becoming "Smart spaces", where sophisticated services are offered to the passengers. The authors concentrate on video streaming provided on buses that move in urban, suburban, or highway environments. A content provider utilizes a DVB-S2 satellite link for transmitting video streams to a bus, where they are relayed to passengers' devices. They say that a bus works in smart mode if it takes advantage of the knowledge of the exact points where fixed obstacles will prevent receiving the satellite signal for a certain time period. This information is sent to the hub via a return channel.
