| 8 | 3 | AUGER, Anne sophie | The application foreseen aims at transmitting various contents (data and video on the downlink), so we choose to use the MPEG-4 coding standard. The associated frame format MP4 is particularly adapted for the encapsulation of multimedia data type (ie video). |

| 15 | 3 | AUGER, Anne sophie | The antenna placed on the aircraft must be compliant with the flight constraints listed in the introduction. Indeed, we should maintain the communication link while the aircraft is performing a turn ( +/- 15° attitude), landing or taking off ( +/- 45° inclination). Therefore, he position of the antenna must be carefully determined in order to be at LOS. |
