System and Method for Low Cost Mobile TV
A low profile low cost mobile in-motion antenna system for satellite TV reception using DVB with different either BPSK or CDMA like modulation schemes is described. In some embodiments, a low resolution version of a video transmission may be used as a backup for a higher resolution version of the video transmission.
1 . A communication apparatus, comprising:
an antenna; and
a communication terminal, which is connected to the antenna and is coupled to receive from a satellite a first signal carrying a given video transmission at a first image resolution and, responsively to an interruption in receiving the first signal, to switch to receiving from a terrestrial wireless network a second signal carrying the given video transmission at a second image resolution that is lower than the first resolution, so as to present the given video transmission to a user over a period of time containing the interruption.
2 . The apparatus according to claim 1 , wherein the terrestrial wireless network comprises a cellular network.
3 . The apparatus according to claim 1 , wherein the first signal is formatted in accordance with a Digital Video Broadcasting (DVB) format.
4 . The apparatus according to claim 1 , wherein the antenna comprises a flat antenna that is adjustable to track the satellite when the apparatus is in motion.
5 . The apparatus according to claim 1 , wherein the communication terminal is further coupled to conduct two-way communication via the satellite.
6 . A method for communication, comprising:
receiving from a satellite a first signal carrying a given video transmission at a first image resolution;
responsively to an interruption in receiving the first signal, switching to receive from a terrestrial wireless network a second signal carrying the given video transmission at a second image resolution that is lower than the first resolution; and
outputting the given video transmission to a user over a period of time containing the interruption.
