Abstract

Claims6
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.
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.
