Environment
The eX3 System is an electronic control data and audio/video distribution system providing digital video and
audio on demand to the passenger seat. The system architecture is modular in design, allowing for additional
components to be integrated without aircraft-side wiring changes. eX3 System employs MPEG encoding
techniques for audio/video data compression providing high-resolution digital video and quality audio to the
seats without using excessive system bandwidth. eX3 system also provides broadband Ethernet network
connectivity between the passenger-computing device at the seat and the head-end network equipment. The
system is used for internet data application and streaming digital audio/video content distribution.
